These config values are relatively static but in some cases they can be called many times in the same request (like rendering a report or a large list of line_items in BOM). These values will now only get fetched from Redis/Postgres once at most per request/job.
For some reason eager-loaded data isn't passed to nested serializers when using associations. Defining the association as a method and passing in some optional paramaters resolves the issue.
This reduces queries run by the controller action by around 75%, as well as the response times.
We found that our database is quite busy querying the country all the
time. One source of these queries is the shop front which serializes
enterprises including their addresses. But addresses should be safe to
cache because:
- country records never change
- state records never change
- updating any other attribute changes the cache key
The caching was previously removed when the state_name attribute was
added. That is technically correct because it's possible to change a
state's name without updating the address. Then the cache would be out
of date. But we never update state names. And if we did, we would need
to invalidate the cache now.
The customer endpoint now serves 2-letter ISO codes for countries and
accepts these for updates. It also serves and accepts region codes
(abbreviations) like VIC for Victoria.
Updates treat these fields as case-insensitive and either code or name
have to be present.
This commit also updates the Swagger documentation.
Strips '+' and ' ' characters from the phone number for the generated
link, but doesn't guarantee the link is valid because the number
registered isn't validated for now.
Australian production had one JPG image which was not recognised as
such. The `content_type` was missing and trying to generate a URL for a
variant raised an error and crashed the page.
Testing for `variable?` includes testing for `attached?` and is more
defensive.
We configured Paperclip to convert images to JPG in some cases but I
omitted that here because we don't need it. If an image is better
represented as PNG or another format then the user should be able to
choose that.
Some specs were also testing the generated URL but the Active Storage
URL doesn't contain a style name anymore and it's not helpful to test
the URL.
