* use `to_represenation` in favor of `get_attribute`
* fix datetime type does get converted to a string
to_representation will convert the datetime field into a string representation. However the to_representation on the method field will only call its underlying method.
* fix add missing import
* apply black formatter
* add test for serializer method field
* apply black format
* improve backward compatibility
by using date's class contructor instead of fromisostring
* apply black format
* fix black format issue
* Include setup.py in black formatting
* Add new flake8 plugins and update errors to look for
* Fix duplicate test name
* Don't use mutable data structure
* Install all dev dependencies for flake8 and black tox envs
Upon success the result was correct but also included:
"errors": [
{
"message": "User Error: expected iterable, but did not find one
for field <SerializerMutation_Subclass>Payload.errors."
}
]
This seemed to be due to Payload.errors defaulting to graphene.List
rather than unset or None. Unsure what exactly changed with 2.x to break
this, so I welcome a better fix, but explicitly setting errors to None
also seems easy enough.
