fh-wfm-workflow-angular

Raincatcher Workflow Angular User Interface

This module is an Angular JS implementation of Workflows for the Raincatcher project.

Setup

This module is packaged in a CommonJS format, exporting the name of the Angular namespace. The module can be included in an angular.js as follows:

var config = {
  mode: 'admin',
  listColumnViewId: 'listColumnView',
  mainColumnViewId: 'detailColumnView'
};

angular.module('app', [
...
, require('fh-wfm-workflow-angular')(config)
...
])

Configuration Options

The following configuration options are available for this module:

mode (Required)

Allows to switch between user based views and admin views. Possible values 'admin' or 'user'

mainColumnViewId (Required)

This is the identifier for the Angular view where the main Workflow views will be rendered.

listColumnViewId (Optional)

This is the identifier for the Angular view where the list of Workflows will be rendered into. This is useful for organising where the lists will be rendered on-screen. If not specified, the lists will be rendered into the mainColumnViewId. This is only used for the admin mode of the module.

toolbarViewId (User Required)

This is the identifier of the Angular view where the progress of a workflow is displayed to the user. This is only required for scenarios where a workflow is being progressed (e.g. in a mobile application)

Workflow Directives

Name	Description
workflow-detail	Displays the workflow to the user and allows re-ordering of the steps.
workflow-form	Allows editing of the workflow name
workflow-list	Displays a list of workflows
workflow-progress	Displays the current progress of a workflow
workflow-result	Displays the result of a single workflow
workflow-step-detail	Displays the detail for a single step of a workflow
workflow-step-form	Allows the user to edit a single step of the workflow

Workflow Step Process

The following directives are used to guide a user through the steps necessary to complete a workflow. The workflow module itself does not contain the logic required for each step, but uses the template directives to render each of the steps to the user.

The workflow-process-parent route is an Angular JS abstract route that is used for all steps in a workflow.

The workflow-process-begin route and controller are used to display the summary of the workflow and any results that there may be.

The workflow-process-steps route publishes topics to get the current state of the workflow for a workorder. Based on the state, the workflow-step directive renders the template defined in the workflow step. At this point, control is passed to the module that implements the individual step.

Topics

As part of rendering Workflows, this module publishes and subscribes to several topics. These topics can be implemented in your application or you can use the fh-wfm-workflow module that already has implementations for these topics.

Published Topics

Each of the following topics subscribes to the error and done topics. If the parameter includes a topicUid, the error topic should have the topicUid appended to the done or error topic.

Topic	Parameters
wfm:workflows:list	NONE
wfm:workflows:read	{id: "IDOFWORKFLOW", topicUID: "IDOFWORKFLOW"}
wfm:workflows:create	{ workflowToCreate: workflowToCreate, topicUid: topicUid}
wfm:workflows:update	{ workflowToUpdate: workflowToCreate, topicUid: topicUid}
wfm:workflows:remove	{ id: "IDOFWORKFLOW, topicUid: "IDOFWORKFLOW"}
wfm:workorders:list	NONE

Step Topics

The following topics allow the updating of the workflow state to progress through a workflow.

Each of the done topics for the following topics contin the following parameters

{
    workflow: {
      //The details of the current workflow being progressed
    },
    workorder: {
      //The details of the current workorder being progressed
    },
    result: {
      //The current result object for this workorder being progressed
    },
    nextStepIndex: 0 //The index of the next step to display
    step: {
        //The details of the step to display
    }
}

Topic	Parameters
wfm:workflows:step:begin	{workorderId: "WORKORDERID", topicUid: "WORKORDERID"}
wfm:workflows:step:summary	{workorderId: "WORKORDERID", topicUid: "WORKORDERID"}
wfm:workflows:step:previous	{workorderId: "WORKORDERID", topicUid: "WORKORDERID"}
wfm:workflows:step:complete	{workorderId: "WORKORDERID", topicUid: "WORKORDERID", submission: {...}, stepCode: "CODEOFCOMPLETEDSTEP"}
