* add test for optional code highlight ('pygments' and 'markdown' packages must be installed)
Closes#5237
Generics/ModelViewset performs filtering on: list, retrieve, put, patch and destroy (plus method equivalents).
i.e. on list plus anything that calls `get_object`.
This PR makes schema generation follow that.
It adds `AutoSchema._allows_filters()` which can be overridden in subclasses.
I’ve made this initially “private” so we can make quick changes if needs be in a 3.7.1 etc.
## Description
The `choices` field for the `ChoiceField` class should be able to be edited after `ChoiceField.__init__` is called.
```
field = ChoiceField(choices=[1,2])
field.choices = [1] # Should no longer allow `2` as a choice
```
Currently, you must update `choices`, `grouped_choices`, and `choice_strings_to_values` to achieve this. This P/R keeps `grouped_choices` and `choice_strings_to_values` in sync whenever the `choices` are edited.
