peewee field with choices

[art1415926535]

Peewee field with a choices argument is not passed to GraphQL.

For example we can modify model from tests:

GENRES = (
    (0, 'Science fiction'),
    (1, 'Guide'),
    (2, 'Horror'),
)

class Book(BaseModel):
    name = CharField()
    year = IntegerField()
    author = ForeignKeyField(Author)
    genre = IntegerField(choices=GENRES)

and modify test:

        book = self.loop.run_until_complete(
            self.manager.create(Book, name='bar', year=2000, author=author, genre=1)  # genre was added
        )

        result = self.loop.run_until_complete(self.query('''
            query {
                book (id: ''' + str(book.id) + ''') {
                    id
                    name
                    year
                    genre  # this
                    author {
                        id
                        name
                        rating
                    }
                }
            }
        '''))

unittest: AssertionError: [GraphQLError('Cannot query field "genre" on type "Book".',)] is not None

I tried to figure point of this error and found what function from graphene return None.

So. What's wrong with my code?

Thanks for reporting. That's definetely a bug in peewee=>graphl field conversion. I will fix it soon.

Well, it was intended to work through Enum but had a little bug in field creation. Having that fixed I realized that using of Enum adds some restrictions and non-obvious value conversions as a result. If you look at the graphene-django implementation there are uppercasing of strings and prefixing of integers. And there are some discussions on this theme: graphql-python/graphene-django#67 graphql-python/graphene-django#133 graphql-python/graphene-django#280 I'm not sure it should be this way so looking back at the issues feedback above I'd rather ignore choices at the moment and just fix the missing field.
