Mimesis: Choice returns UnsupportedField when used with Field

[cryocaustik]

Bug report

What's wrong

I was attempting to use choice within Schema generation to pick from a list of options but ran into an UnsupportedField error.

It would appear that AbsrtractField returns UnsupportedField when used with on Choice provider.

Example:

>>> from mimesis.schema import Field, Schema
>>> _ = Field('en')
>>> _('choice', items=[1,2,3])
Traceback (most recent call last):
  File "C:\dev\fakemimesis\.pyenv\lib\site-packages\mimesis\schema.py", line 100, in __call__
    result = self._table[name](**kwargs)
KeyError: 'choice'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#24>", line 1, in <module>
    _('choice', items=[1,2,3])
  File "C:\dev\fakemimesis\.pyenv\lib\site-packages\mimesis\schema.py", line 105, in __call__
    raise UnsupportedField(name)
mimesis.exceptions.UnsupportedField: Field «choice» is not supported.

Seems like a bug. Field and Schema use Generic which has an attribute choice, so it must work.

[lk-geimfari]

It happens because of implementation of Choice provider. We need to think about how to fix it.

@cryocaustik Here is a workaround if you really need to use it:

from mimesis.schema import Field, Schema
from mimesis.providers import Choice

class Choice(Choice):
    def choice(self, *args, **kwargs):
        return self.__call__(*args, **kwargs)


_ = Field('en', providers=(Choice,))

_('choice', items=[1, 3, 4])

Thanks! I ended doing something similar but with a custom provider.

I would like to fix that bug and create a new release, but I'm really extremely busy, so I hope that I can fix it on weekends.

[lk-geimfari]

So, this issue has been fixed. We will publish a release as soon as possible.

It's done. 3.1.0 has been released. Thanks for the bug report!
