When creating or updating an organisation an itegrity error is raise if the name is already used.
This change adds a new error handler for the organisation to catch the named unique index and return a 400 with a sensible message.
We have an other error handler for unique service names which was caught in the error handler for all blueprints. A new error handler for the service_blueprint has been created for catch those specific unique constraints.
This is a nice way to encapulate the specific errors for a specific blueprint.
If the organisation name that is being inserted or updated is not unique we just want to return a 400 to the admin app.
Updated the code so that we are not logging.exception, this is because a cloud watch alert is set to the support team. This type of error is not something we need to investigate.
- Changed the organisation DAO update method to only make 1 query
- Updated the update rest endpoint to not return an organisation when
the update is successful
notable things that have been kept until migration is complete:
* passing in `organisation` to update_service will update email branding
* both `/email-branding` and `/organisation` hit the same code
* service endpoints still return organisation as well as email branding
