Provide an API end-point for querying postcode by place name

[digitalWestie]

A new endpoint at api/v4/postcodes. Should take form of a view living in aliss/api/v4_views.py.

Relevant docs:

• API views: https://www.django-rest-framework.org/api-guide/generic-views/
• Serializing json responses: https://www.django-rest-framework.org/api-guide/serializers/

Any requests should provide a q param, which are used to to filter results (istartswith is prob best for this).

The Postcode table has been updated to add a column with place names.

• Need to add an endpoint for querying place names.
• Update the autocomplete code to use the endpoint rather than the hard-coded locations.
• Need to create a view which takes a query with a minimum of three letters and returns a json collection of matching names.
• Something like /api/places/?q=Abe

Basic view returning a dictionary of place_names and postcode.

Filtering the data set but not with proper url format?

[Mike-Heneghan]

Updated the API view for post-code locations to take a query q and filter results which start with that.

[Mike-Heneghan]

Need to now query the api for the place_name and postcode rather than using the hard coated data.

The api is now successfully returning the place_name and postcode data for the Easy-Autocomplete feature.

To do list:

• [ ] Ensure the API isn't exposed (disable CORS)?
• [ ] Write tests for the new API endpoint.
• [ ] Send PR.

Don't worry about API exposure for now, we can deal with it later, as team are making noises about this.

I've also been trying to write a test although currently, I'm not getting responses as I would expect. When manually testing the locations are returned as per the google drive link above.

As this is a priority I'll send the PR and we can discuss tests and API exposure when it's convenient.

Merged into master.
