DeepDesk

DeepDesk is a framework designed for a common database across multiple applications.

It features the following submodules:

data: json file based database system with indexing, full text search, record templates, validation, navigation aliases and more!

from deepdesk import * root=data.Root('./root') template=root.Record( ... "template/user", ... { ... 'email':data.Index(data.Validate("", 'email'), "user/email"), ... 'profile':data.Key('profile/') ... }) template.hash = True template.version = 1 template.save()

By setting template.hash to True, we are telling deepdesk to include the hash and salt fields in records created from this template. These are automatically included if a password is set, but by doing this now we can use it later to display a password field for records that have a hash attribute.

As we might alter templates and need a history of changes for managing data updates, set version to 1 to enable versioning on the record.

We can now use this template to create a user. A trailing back slash ("/") on the key tells deepdesk that there is a template for this record and it will generate a uuid for the rest of the location.

user=root.Record("user/", {'email':"domino@@example.com"}) user['email'].isvalid False user['email'] = "[e-mail]" user['email'].isvalid True user.password = "example.password" user.save()

Now we haved saved the user, we can find it from the "user/email" index.

indexfile = root.IndexFile("user/email") indexfile.lookup("[e-mail]") 'user/ae4df406/f166/4a75/be34/c0742a029f24' test = root.Record('user/ae4df406/f166/4a75/be34/c0742a029f24') test.password == "another.password" False test.password == "example.password" True test.password <password._HashedPassword object at 0x7fa70467cb10> test.base 'template/user.0001' str(test) "{'email': Index(Validate('[e-mail]', 'email'), 'user/email'), 'profile': Key('profile/')}"

As well as Index, there are Alias, Collect, Group, Search and Include field wrappers which you can use to help navigate the database.

root.init()

This imports schema.org to the database, check the code for the field wrappers used :-)

root.search("about") {'schema.org/AboutPage', 'schema.org/about'} root.browse("menu/schema.org") ['Data Type', 'Thing', 'Data Type.json', 'Thing.json'] root.browse("menu/schema.org/Data Type") ['Time.json', 'Text.json', 'Date.json', 'Number.json', 'Number', 'Date Time.json', 'Boolean.json', 'Text'] t = root.Record("menu/schema.org/Data Type/Time.json") t.key Key('schema.org/Time') t.fields.keys() dict_keys(['supertypes', 'ancestors', 'specific_properties', 'id', 'url', 'subtypes', 'properties', 'comment', 'comment_plain', 'label']) t['url'] 'http://schema.org/Time'
