[mtreacy002]

Description

Refactor POST and PUT /user/additional_info to one api endpoint

Fixes #100

Type of Change:

• Code

Code/Quality Assurance Only

• New feature (non-breaking change which adds functionality pre-approved by mentors)

How Has This Been Tested?

• login as user who has no additional info record
• send GET /user/personal_details request to get user id
• send PUT /user/additional_info to create additional info data. See success response 201 Created if additional info instance is successfully created.

• Now update the details and resend PUT /user/additional_info. On success update, see response 200 OK.

Update @anitab-org/bridgeintech-maintainers . I've refactor POST and PUT /user/additional_info. Now backend only has one endpoint (PUT /user/additional_info) that will do either Create or Update user additional info. Please review when you have time. Thanks

Note @anitab-org/bridgeintech-maintainers. I've just pushed a typo fix for mocking test patch on test create, now using requests.put patch instead of post

[mtreacy002]

Update @anitab-org/bridgeintech-maintainers . I've just pushed the last change to this refactoring PRR (hopefully). Now Create personal background dao is removed as there's no need for this anymore.

Sorry I didn't know if userextension is synonymous to user_additional_info. If it is then this also seems fine 👍

[meenakshi-dhanani]

Just did a code review seems fine.
