To register a component, you need to create a setting.py file in the root of your project.
This file will be used to register your classes and productions.
e.g.: setting.py
from iop import Utils
import bo
CLASSES = {
"Python.MyBusinessOperation": bo.MyBusinessOperation
}
Then you can use the iop command line to register your component.
iop --migrate /path/to/your/project/setting.py
You can find a demo in the src/python/demo folder.
Other demos are aviailable in those repositories:
zpm "install pex-embbeded-python"
pip3 install iris-pex-embedded-python
Import the ObjectScript classes, open an embedded python shell and run :
from iop import Utils
Utils.setup()
or use iop command line :
iop --init
If the module is not updated, make sure to remove the old version :
pip3 uninstall iris-pex-embedded-python
or manually remove the grongier folder in <iris_installation>/lib/python/
or force the installation with pip :
pip3 install --upgrade iris-pex-embedded-python --target <iris_installation>/lib/python/
In order to have access to the InterSystems images, we need to go to the following url: http://container.intersystems.com. After connecting with our InterSystems credentials, we will get our password to connect to the registry. In the docker VScode addon, in the image tab, by pressing connect registry and entering the same url as before (http://container.intersystems.com) as a generic registry, we will be asked to give our credentials. The login is the usual one but the password is the one we got from the website.
From there, we should be able to build and compose our containers (with the docker-compose.yml and Dockerfile files given).
This repository is ready for VS Code.
Open the locally-cloned interoperability-embedeed-python folder in VS Code.
If prompted (bottom right corner), install the recommended extensions.
IMPORTANT: When prompted, reopen the folder inside the container so you will be able to use the python components within it. The first time you do this it may take several minutes while the container is readied.
By opening the folder remote you enable VS Code and any terminals you open within it to use the python components within the container. Configure these to use /usr/irissys/bin/irispython
To open the production you can go to production.
You can also click on the bottom on the 127.0.0.1:52773[IRISAPP] button and select Open Management Portal then, click on [Interoperability] and [Configure] menus then click [productions] and [Go].
The production already has some code sample.
Here we can see the production and our pure python services and operations:
New json trace for python native messages :
A dockerfile which install some python dependancies (pip, venv) and sudo in the container for conviencies. Then it create the dev directory and copy in it this git repository.
It starts IRIS and activates %Service_CallIn for Python Shell. Use the related docker-compose.yml to easily setup additional parametes like port number and where you map keys and host folders.
This dockerfile ends with the installation of requirements for python modules.
Use .env/ file to adjust the dockerfile being used in docker-compose.
Settings file to let you immedietly code in VSCode with VSCode ObjectScript plugin
Config file if you want to debug with VSCode ObjectScript
Read about all the files in this article
Recommendation file to add extensions if you want to run with VSCode in the container.
This is very useful to work with embedded python.

__init__.pyfileThis file will allow us to create the classes to import in the code.
It gets from the multiple files seen earlier the classes and make them into callable classes.
That way, when you wish to create a business operation, for example, you can just do:
from iop import BusinessOperation
common classThe common class shouldn't be called by the user, it defines almost all the other classes.
This class defines:
on_init: The on_init() method is called when the component is started.
Use the on_init() method to initialize any structures needed by the component.
on_tear_down: Called before the component is terminated.
Use it to free any structures.
on_connected: The on_connected() method is called when the component is connected or reconnected after being disconnected.
Use the on_connected() method to initialize any structures needed by the component.
log_info: Write a log entry of type "info". :log entries can be viewed in the management portal.
log_alert: Write a log entry of type "alert". :log entries can be viewed in the management portal.
log_warning: Write a log entry of type "warning". :log entries can be viewed in the management portal.
log_error: Write a log entry of type "error". :log entries can be viewed in the management portal.
business_host classThe business host class shouldn't be called by the user, it is the base class for all the business classes.
This class defines:
send_request_sync: Send the specified message to the target business process or business operation synchronously.
Parameters:
Returns: the response object from target.
Raises: TypeError: if request is not of type Message or IRISObject.
send_request_async: Send the specified message to the target business process or business operation asynchronously.
Parameters:
Raises: TypeError: if request is not of type Message or IRISObject.
get_adapter_type: Name of the registred Adapter.
inbound_adapter classInbound Adapter in Python are subclass from iop.InboundAdapter in Python, that inherit from all the functions of the common class.
This class is responsible for receiving the data from the external system, validating the data, and sending it to the business service by calling the BusinessHost process_input method.
This class defines:
on_task: Called by the production framework at intervals determined by the business service CallInterval property.
The message can have any structure agreed upon by the inbound adapter and the business service.
Example of an inbound adapter ( situated in the src/python/demo/reddit/adapter.py file ):
from iop import InboundAdapter
import requests
import iris
import json
class RedditInboundAdapter(InboundAdapter):
"""
This adapter use requests to fetch self.limit posts as data from the reddit
API before calling process_input for each post.
"""
def on_init(self):
if not hasattr(self,'feed'):
self.feed = "/new/"
if self.limit is None:
raise TypeError('no Limit field')
self.last_post_name = ""
return 1
def on_task(self):
self.log_info(f"LIMIT:{self.limit}")
if self.feed == "" :
return 1
tSC = 1
# HTTP Request
try:
server = "https://www.reddit.com"
request_string = self.feed+".json?before="+self.last_post_name+"&limit="+self.limit
self.log_info(server+request_string)
response = requests.get(server+request_string)
response.raise_for_status()
data = response.json()
updateLast = 0
for key, value in enumerate(data['data']['children']):
if value['data']['selftext']=="":
continue
post = iris.cls('dc.Reddit.Post')._New()
post._JSONImport(json.dumps(value['data']))
post.OriginalJSON = json.dumps(value)
if not updateLast:
self.LastPostName = value['data']['name']
updateLast = 1
response = self.BusinessHost.ProcessInput(post)
except requests.exceptions.HTTPError as err:
if err.response.status_code == 429:
self.log_warning(err.__str__())
else:
raise err
except Exception as err:
self.log_error(err.__str__())
raise err
return tSC
outbound_adapter classOutbound Adapter in Python are subclass from iop.OutboundAdapter in Python, that inherit from all the functions of the common class.
This class is responsible for sending the data to the external system.
The Outbound Adapter gives the Operation the possibility to have a heartbeat notion. To activate this option, the CallInterval parameter of the adapter must be strictly greater than 0.
Example of an outbound adapter ( situated in the src/python/demo/reddit/adapter.py file ):
class TestHeartBeat(OutboundAdapter):
def on_keepalive(self):
self.log_info('beep')
def on_task(self):
self.log_info('on_task')
business_service classThis class is responsible for receiving the data from external system and sending it to business processes or business operations in the production.
The business service can use an adapter to access the external system, which is specified overriding the get_adapter_type method.
There are three ways of implementing a business service:
Polling business service with an adapter - The production framework at regular intervals calls the adapter’s OnTask() method, which sends the incoming data to the the business service ProcessInput() method, which, in turn calls the OnProcessInput method with your code.
Polling business service that uses the default adapter - In this case, the framework calls the default adapter's OnTask method with no data. The OnProcessInput() method then performs the role of the adapter and is responsible for accessing the external system and receiving the data.
Nonpolling business service - The production framework does not initiate the business service. Instead custom code in either a long-running process or one that is started at regular intervals initiates the business service by calling the Director.CreateBusinessService() method.
Business service in Python are subclass from iop.BusinessService in Python, that inherit from all the functions of the business host.
This class defines:
on_process_input: Receives the message from the inbond adapter via the PRocessInput method and is responsible for forwarding it to target business processes or operations.
If the business service does not specify an adapter, then the default adapter calls this method with no message and the business service is responsible for receiving the data from the external system and validating it.
Parameters:
Example of a business service ( situated in the src/python/demo/reddit/bs.py file ):
from iop import BusinessService
import iris
from message import PostMessage
from obj import PostClass
class RedditServiceWithPexAdapter(BusinessService):
"""
This service use our python Python.RedditInboundAdapter to receive post
from reddit and call the FilterPostRoutingRule process.
"""
def get_adapter_type():
"""
Name of the registred Adapter
"""
return "Python.RedditInboundAdapter"
def on_process_input(self, message_input):
msg = iris.cls("dc.Demo.PostMessage")._New()
msg.Post = message_input
return self.send_request_sync(self.target,msg)
def on_init(self):
if not hasattr(self,'target'):
self.target = "Python.FilterPostRoutingRule"
return
business_process classTypically contains most of the logic in a production.
A business process can receive messages from a business service, another business process, or a business operation.
It can modify the message, convert it to a different format, or route it based on the message contents.
The business process can route a message to a business operation or another business process.
Business processes in Python are subclass from iop.BusinessProcess in Python, that inherit from all the functions of the business host.
This class defines:
on_request: Handles requests sent to the business process. A production calls this method whenever an initial request for a specific business process arrives on the appropriate queue and is assigned a job in which to execute.
Parameters:
Returns: An instance of IRISObject or subclass of Message that contains the response message that this business process can return to the production component that sent the initial message.
on_response: Handles responses sent to the business process in response to messages that it sent to the target.
A production calls this method whenever a response for a specific business process arrives on the appropriate queue and is assigned a job in which to execute.
Typically this is a response to an asynchronous request made by the business process where the responseRequired parameter has a true value.
Parameters:
Returns: An instance of IRISObject or subclass of Message that contains the response message that this business process can return to the production component that sent the initial message.
on_complete: Called after the business process has received and handled all responses to requests it has sent to targets.
Parameters:
Returns: An instance of IRISObject or subclass of Message that contains the response message that this business process can return to the production component that sent the initial message.
Example of a business process ( situated in the src/python/demo/reddit/bp.py file ):
from iop import BusinessProcess
from message import PostMessage
from obj import PostClass
class FilterPostRoutingRule(BusinessProcess):
"""
This process receive a PostMessage containing a reddit post.
It then understand if the post is about a dog or a cat or nothing and
fill the right infomation inside the PostMessage before sending it to
the FileOperation operation.
"""
def on_init(self):
if not hasattr(self,'target'):
self.target = "Python.FileOperation"
return
def on_request(self, request):
if 'dog'.upper() in request.post.selftext.upper():
request.to_email_address = 'dog@company.com'
request.found = 'Dog'
if 'cat'.upper() in request.post.selftext.upper():
request.to_email_address = 'cat@company.com'
request.found = 'Cat'
if request.found is not None:
return self.send_request_sync(self.target,request)
else:
return
business_operation classThis class is responsible for sending the data to an external system or a local system such as an iris database.
The business operation can optionally use an adapter to handle the outgoing message which is specified overriding the get_adapter_type method.
If the business operation has an adapter, it uses the adapter to send the message to the external system.
The adapter can either be a PEX adapter, an ObjectScript adapter or a python adapter.
Business operation in Python are subclass from iop.BusinessOperation in Python, that inherit from all the functions of the business host.
In a business operation it is possbile to create any number of function similar to the on_message method that will take as argument a typed request like this my_special_message_method(self,request: MySpecialMessage).
The dispatch system will automatically analyze any request arriving to the operation and dispacth the requests depending of their type. If the type of the request is not recognized or is not specified in any on_message like function, the dispatch system will send it to the on_message function.
This class defines:
on_message: Called when the business operation receives a message from another production component that can not be dispatched to another function.
Typically, the operation will either send the message to the external system or forward it to a business process or another business operation.
If the operation has an adapter, it uses the Adapter.invoke() method to call the method on the adapter that sends the message to the external system.
If the operation is forwarding the message to another production component, it uses the SendRequestAsync() or the SendRequestSync() method.
Parameters:
Returns: The response object
Example of a business operation ( situated in the src/python/demo/reddit/bo.py file ):
from iop import BusinessOperation
from message import MyRequest,MyMessage
import iris
import os
import datetime
import smtplib
from email.mime.text import MIMEText
class EmailOperation(BusinessOperation):
"""
This operation receive a PostMessage and send an email with all the
important information to the concerned company ( dog or cat company )
"""
def my_message(self,request:MyMessage):
sender = 'admin@example.com'
receivers = 'toto@example.com'
port = 1025
msg = MIMEText(request.toto)
msg['Subject'] = 'MyMessage'
msg['From'] = sender
msg['To'] = receivers
with smtplib.SMTP('localhost', port) as server:
server.sendmail(sender, receivers, msg.as_string())
print("Successfully sent email")
def on_message(self, request):
sender = 'admin@example.com'
receivers = [ request.to_email_address ]
port = 1025
msg = MIMEText('This is test mail')
msg['Subject'] = request.found+" found"
msg['From'] = 'admin@example.com'
msg['To'] = request.to_email_address
with smtplib.SMTP('localhost', port) as server:
# server.login('username', 'password')
server.sendmail(sender, receivers, msg.as_string())
print("Successfully sent email")
If this operation is called using a MyRequest message, the my_message function will be called thanks to the dispatcher, otherwise the on_message function will be called.
director classThe Director class is used for nonpolling business services, that is, business services which are not automatically called by the production framework (through the inbound adapter) at the call interval.
Instead these business services are created by a custom application by calling the Director.create_business_service() method.
This class defines:
create_business_service: The create_business_service() method initiates the specified business service.
Parameters:
Returns: an object that contains an instance of IRISBusinessService
start_production: The start_production() method starts the production.
Parameters:
stop_production: The stop_production() method stops the production.
Parameters:
restart_production: The restart_production() method restarts the production.
Parameters:
list_productions: The list_productions() method returns a dictionary of the names of the productions that are currently running.
objectsWe will use dataclass to hold information in our messages in a obj.py file.
Example of an object ( situated in the src/python/demo/reddit/obj.py file ):
from dataclasses import dataclass
@dataclass
class PostClass:
title: str
selftext : str
author: str
url: str
created_utc: float = None
original_json: str = None
messagesThe messages will contain one or more objects, located in the obj.py file.
Messages, requests and responses all inherit from the iop.Message class.
These messages will allow us to transfer information between any business service/process/operation.
Example of a message ( situated in the src/python/demo/reddit/message.py file ):
from iop import Message
from dataclasses import dataclass
from obj import PostClass
@dataclass
class PostMessage(Message):
post:PostClass = None
to_email_address:str = None
found:str = None
WIP It is to be noted that it is needed to use types when you define an object or a message.
You can register a component to iris in many way :
register_componentregister_fileregister_folderStart an embedded python shell :
/usr/irissys/bin/irispython
Then use this class method to add a new py file to the component list for interoperability.
from iop import Utils
Utils.register_component(<ModuleName>,<ClassName>,<PathToPyFile>,<OverWrite>,<NameOfTheComponent>)
e.g :
from iop import Utils
Utils.register_component("MyCombinedBusinessOperation","MyCombinedBusinessOperation","/irisdev/app/src/python/demo/",1,"PEX.MyCombinedBusinessOperation")
Start an embedded python shell :
/usr/irissys/bin/irispython
Then use this class method to add a new py file to the component list for interoperability.
from iop import Utils
Utils.register_file(<File>,<OverWrite>,<PackageName>)
e.g :
from iop import Utils
Utils.register_file("/irisdev/app/src/python/demo/bo.py",1,"PEX")
Start an embedded python shell :
/usr/irissys/bin/irispython
Then use this class method to add a new py file to the component list for interoperability.
from iop import Utils
Utils.register_folder(<Path>,<OverWrite>,<PackageName>)
e.g :
from iop import Utils
Utils.register_folder("/irisdev/app/src/python/demo/",1,"PEX")
Start an embedded python shell :
/usr/irissys/bin/irispython
Then use this static method to migrate the settings file to the iris framework.
from iop import Utils
Utils.migrate()
This file is used to store the settings of the interoperability components.
It has two sections :
CLASSES : This section is used to store the classes of the interoperability components.PRODUCTIONS : This section is used to store the productions of the interoperability components.e.g :
import bp
from bo import *
from bs import *
CLASSES = {
'Python.RedditService': RedditService,
'Python.FilterPostRoutingRule': bp.FilterPostRoutingRule,
'Python.FileOperation': FileOperation,
'Python.FileOperationWithIrisAdapter': FileOperationWithIrisAdapter,
}
PRODUCTIONS = [
{

}
]
}
}
]
This section is used to store the classes of the interoperability components.
It aims to help to register the components.
This dictionary has the following structure :
module : Name of the module of the component (optional)class : Name of the class of the component (optional)path : The path of the component (mandatory)e.g :
When Value is a class or a module:
import bo
import bp
from bs import RedditService
CLASSES = {
'Python.RedditService': RedditService,
'Python.FilterPostRoutingRule': bp.FilterPostRoutingRule,
'Python.FileOperation': bo,
}
When Value is a dictionary :
CLASSES = {
'Python.RedditService': {
'module': 'bs',
'class': 'RedditService',
'path': '/irisdev/app/src/python/demo/'
},
'Python.Module': {
'module': 'bp',
'path': '/irisdev/app/src/python/demo/'
},
'Python.Package': {
'path': '/irisdev/app/src/python/demo/'
},
}
This section is used to store the productions of the interoperability components.
It aims to help to register a production.
This list has the following structure :
dc.Python.Production : The name of the production
@Name : The name of the production@TestingEnabled : The testing enabled of the production@LogGeneralTraceEvents : The log general trace events of the productionDescription : The description of the productionActorPoolSize : The actor pool size of the productionItem : The list of the items of the production
@Name : The name of the item@Category : The category of the item@ClassName : The class name of the item@PoolSize : The pool size of the item@Enabled : The enabled of the item@Foreground : The foreground of the item@Comment : The comment of the item@LogTraceEvents : The log trace events of the item@Schedule : The schedule of the itemSetting : The list of the settings of the item
@Target : The target of the setting@Name : The name of the setting#text : The value of the settingThe minimum structure of a production is :
PRODUCTIONS = [
{
'UnitTest.Production': {
"Item": [
{
"@Name": "Python.FileOperation",
"@ClassName": "Python.FileOperation",
},
{
"@Name": "Python.EmailOperation",
"@ClassName": "UnitTest.Package.EmailOperation"
}
]
}
}
]
You can also set in @ClassName an item from the CLASSES section.
e.g :
from bo import FileOperation
PRODUCTIONS = [
{
'UnitTest.Production': {
"Item": [
{
"@Name": "Python.FileOperation",
"@ClassName": FileOperation,
}
]
}
}
]
As the production is a dictionary, you can add in value of the production dictionary an environment variable.
e.g :
import os
PRODUCTIONS = [
{
'UnitTest.Production': {
"Item": [
{
"@Name": "Python.FileOperation",
"@ClassName": "Python.FileOperation",
"Setting": {
"@Target": "Host",
"@Name": "%settings",
"#text": os.environ['SETTINGS']
}
}
]
}
}
]
If you don't want to use the register_component util. You can add a IOP.BusinessService component directly into the management portal and configure the properties :
e.g :
Since version 2.3.1, you can use the command line to register your components and productions.
To use it, you have to use the following command :
iop
output :
usage: python3 -m iop [-h] [-d DEFAULT] [-l] [-s START] [-k] [-S] [-r] [-M MIGRATE] [-e EXPORT] [-x] [-v] [-L]
optional arguments:
-h, --help display help and default production name
-d DEFAULT, --default DEFAULT
set the default production
-l, --lists list productions
-s START, --start START
start a production
-k, --kill kill a production (force stop)
-S, --stop stop a production
-r, --restart restart a production
-M MIGRATE, --migrate MIGRATE
migrate production and classes with settings file
-e EXPORT, --export EXPORT
export a production
-x, --status status a production
-v, --version display version
-L, --log display log
default production: PEX.Production
The help command display the help and the default production name.
iop -h
output :
usage: python3 -m iop [-h] [-d DEFAULT] [-l] [-s START] [-k] [-S] [-r] [-M MIGRATE] [-e EXPORT] [-x] [-v] [-L]
...
default production: PEX.Production
The default command set the default production.
With no argument, it display the default production.
iop -d
output :
default production: PEX.Production
With an argument, it set the default production.
iop -d PEX.Production
The lists command list productions.
iop -l
output :
{
"PEX.Production": {
"Status": "Stopped",
"LastStartTime": "2023-05-31 11:13:51.000",
"LastStopTime": "2023-05-31 11:13:54.153",
"AutoStart": 0
}
}
The start command start a production.
To exit the command, you have to press CTRL+C.
iop -s PEX.Production
output :
2021-08-30 15:13:51.000 [PEX.Production] INFO: Starting production
2021-08-30 15:13:51.000 [PEX.Production] INFO: Starting item Python.FileOperation
2021-08-30 15:13:51.000 [PEX.Production] INFO: Starting item Python.EmailOperation
...
The kill command kill a production (force stop).
Kill command is the same as stop command but with a force stop.
Kill command doesn't take an argument because only one production can be running.
iop -k
The stop command stop a production.
Stop command doesn't take an argument because only one production can be running.
iop -S
The restart command restart a production.
Restart command doesn't take an argument because only one production can be running.
iop -r
The migrate command migrate a production and classes with settings file.
Migrate command must take the absolute path of the settings file.
Settings file must be in the same folder as the python code.
iop -M /tmp/settings.py
The export command export a production.
If no argument is given, the export command export the default production.
iop -e
If an argument is given, the export command export the production given in argument.
iop -e PEX.Production
output :
