Graphene-django - 使用枚举改变类型

Question

So, I have the following model:

class Semester(models.Model):
    course = models.ManyToManyField(Course, through='CourseSemester')

    class SemesterType(models.TextChoices):
        A = 'A', 'Winter'
        B = 'B', 'Spring'
        SUMMER = 'SU', 'Summer'

    name = models.CharField(
        max_length=200,
        choices=SemesterType.choices,
        default=SemesterType.A,
    )
    year = models.IntegerField()

I try to add a mutation to add a new semester. Graphene-django seems to automatically generate an Enum field for me, but how can I get it inside the arguments?

According to the github issues, something like SemesterType._meta.fields['name'] should work, but I can't get it right, even with wrapping it inside graphene.Argument .

It is possible to tell Graphene not to convert it to Enum, however I'd rather avoid that if possible.

Any clue how to get that right?

Answer 1

You should add convert_choices_to_enum = False to your DjangoObjectType

More information is in documentation in Choices to Enum conversion section
