Fix doc and test on ES6 python client compat
This commit changes the statement that version < 6.3.1 of the
elasticsearch python client should be used to instead state
that 6.4.0 is fine.
It also update the tests to reflect the statement.
Initially the `update_all_types` argument has been used to work
around an issue described in:
https://github.com/wagtail/wagtail/issues/2968
This argument was removed in elasticsearch-py 6.3.1 and making
use of it was raising an error.
With 6.4.0 nothing is raising anymore.
Resolves "DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working" - see #5484
The USERNAME_FIELD exists to allow customisation. Therefore we should make an assumption that `.username` exists on the model. Instead, we need to pull the required value from the USERNAME_FIELD and add in a fallback default.
revisions_for_moderation() was iterating over Page instances only
to use their path attribute. The optimization uses values_list()
over the GroupPagePermission queryset to retrieve only the page
paths without having to create the model instances in memory. This
saves roughly 50% of the runtime.
The string of self.form is the same as form.as_table - which is too verbose.
This updates the __repr__ of EditHandler/FieldPanel to show the class name of the form being used instead (or NoneType if it's None).
This generated block of code needs to stay or else there will be an error while running ./manage.py migrate. It is misleading that it is not included in this tutorial.
* Fetch new translations from Transifex, update contributors, add new languages with >90% coverage to WAGTAILADMIN_PROVIDED_LANGUAGES
* Update transifex config to download Chinese (Simplified) and Chinese (Traditional) translations as zh_Hans and zh_Hant respectively
* Fix get-translator-credits.py to recognise 'tet' as the locale string for Tetum (which Babel doesn't)
There was a small bug in the page chooser, where it would display
`page.title` instead of `get_admin_display_title` when loaded on with a
specified parent. This was because the page chooser was falling back to
Page.get_admin_display_title instead of the specific kind
