Problem Statement

...

Solution approach to overcome the problem has below componentsapproaches

APPROACH 1
  1. Sunbird Platform will expose an API for end user to initiate update content
  2. Sunbird Platform will log the request in DB and pass the user a generated process Id
  3. Sunbird Platform will send the request with processId to kafka message queue
  4. Request will be picked up by Learning platform and would start the processing of update content based on the request
  5. Sunbird Platform will use a listener to get the status update and store in DB from the kafka based on processId
Approach 2
  1. Sunbird Platform will expose an API for end user to initiate update content
  2. Sunbird Platform will internally call Content Service with the request provided by User.
  3. Content Service will validate the requestWith valid request, Content Service will initiate the update process through kafka pipeline and will return unique process ID identifying the process.
  4. With Invalid request, Content Service will return error message which Sunbird platform will return to User
  5. For valid response from Content Service, processId with other details will be saved in Sunbird platform DB
  6. On user call to get status, Sunbird Platform will call Content Service. 


pros and cons of both approaches

approaches proscons

1.without content service

loosely coupled
2.with content service 

dependent on content service,

duplicate storage of statuses and processes

by Content Service and Sunbird platform

Problem Statement

What is the API for update content?

Solution approach

URL:

POST /v1/contentjob/updatestart

Headers:

Authorization

X-authenticated-user-token

Request Params:

nametype description
script
scriptNameStringname of the script to be run by Content Service
versionStringthe version of the script
content
attributes
Mapadditional parameters which would
Arrayattributes to be updated, will work as arguments
for
to the
scripts
script

Response Params:

nametypedescription
processIdStringunique identifier of the process started for the request, needed to get the status of the process

Errors:

status codeerror codeerror message
400MANDATORY_PARAMETER_MISSINGMandatory parameter {script,version} is missing.
400UPDATE_FAILED
Data updation failed due to invalid Request

Sample Request and Response:


No Format
nopaneltrue
Request

{
	request : {
		"scriptscriptName" : "course_rename",
		"version" : "1.2",
		"attributes" : [{
			"field" : "name"
			"oldValue" : "AB",
			"newValue" : "ab"
		},{
			"contentfield" : "orgDetails"
			"oldValue" : {
				"oldNamecourseName" : "AB"
			},
			"newNamenewValue" : {
				"courseName" : "ab"
			}
		}]	
	}
}

Response

{
  "id": "api.content.updatejob",
  "result": {
		"processId" : "01262366359399628812"
	}
}
