Before, the delete decorator would delete the keys from Redis and then
we made the request to api to change the data. However, it is possible
that the cache could get re-populated in between these two things
happening, and so would cache outdated data.
This changes the order to send the api request first. We then always
delete the specified keys from Redis. Changing the order of the code in
the decorator changes the order in which the cache keys get deleted, so
the tests have been updated.
when clients are defined in app/__init__.py, it increases the chance of
cyclical imports. By moving module level client singletons out to a
separate extensions file, we stop cyclical imports, but keep the same
code flow - the clients are still initialised in `create_app` in
`__init__.py`.
The redis client in particular is no longer separate - previously redis
was set up on the `NotifyAdminAPIClient` base class, but now there's one
singleton in `app.extensions`. This was done so that we can access redis
from outside of the existing clients.
This commit adds logic to:
- take the list of selected folders and templates
- split it into two lists (of folders and templates)
- `POST` that data to the API, to effect the movement of said folders
and templates
I’ve tried to architect it in such a way that we can easily add more
template ‘operations’ in the future, as we add more forms to the choose
template page.
The add new templates page now has option to add template folders.
Tweaked wording of other options and h1 to clarify options since it's
not all about templates any more.
Added api client and stuff for it
