Opal

Exclude many to one relationships from the advanced search

Many to one fields are no longer visible in the advanced search screen.

Advanced search changes
Date and datetime fields now support `Equals` along with `Before` and `After`

Application.modify_extract

A list of functions attached to the application object that
enable the application to add, remove or alter files in an
advanced search extract.

Include ID in the extract

The model ID will no longer be excluded from its csv extract. If present, id will appear first, then patient id, then episode id.

Celery upgrade and Django Celery library change.
`django-celery` only officially supports Python 3.5 which Opal no longer supports. It is also no longer the recommended solution for results by Celery. So we have removed this dependency and added the `django-celery-results` module that has a similar functionality.

Drops support for Python 3.5
Opal now supports Python 3.6 - Python 3.8.

Python 3 version changes.

Opal now supports Python 3.5 - Python 3.8.
Please note that the 0.21.0 release will drop support for Python 3.5.

Scaffold application episode category

The scaffolded application created by `startproject` now creates a custom
episode category class.

Removes Django Axes

Axes has been removed from the Opal core application. The package creates a database
log of all login attempts and was installed by default. It is now considered that this
should be an application level choice rather than a framework choice. Installing it on a
per application basis is simple, and requires only settings and requirements changes.

Removes Letter

The dependency on the letter python package has been removed from the Opal core application. If you wish to send emails, Django ships with email wrappers to make this easy.

Some models have translations
Episodes/Patients/Demographics now use use gettext_lazy on all their fields

PatientListCtrl.refresh and PatientDetailCtrl.refresh return promises
PatientListCtrl.refresh and PatientDetailCtrl.refresh now return a promise which resolves after the refresh is complete.

Removes scroll to top
Removes the directory `scrolllto-top` as this is not commonly used. `go-to-top` is directive that is a a drop in replacement that will take the user up to the top of the page but without scrolling.

Remove shortDate and shortDateTime
The angular filters shortDate and shortDateTime have been deprecated for some time.

Stop an index being passed to recordEditor.editItem
recordEditor.editItem used to take either a number or an item (subrecord) as its second argument.
Now it will only take an item.

Removes the account page
Removes the user account detail page as this is not tested/used and can be easily created within an app.

Complex objects are now serialized in the extract as json
If you have a dictionary, or a list of dictionaries returned by Subrecord.to_dict, these will now be serialized into
the dictionary as json, rather than str(dict)
