I am trying to change my rest end points to graphql and I had a library called TaggableManager as one of the model fields. Anyone know how this can work with graphql?

推荐答案

您必须明确告诉graphene如何转换 TaggableManger 字段以在查询中使用.在将模型与查询或中的 TaggableManger 字段一起使用之前，从 graphene_django.converter 注册 @convert_django_field .突变.

You have to explicitly tell graphene how to convert the TaggableManger field to be used in Queries. Register @convert_django_field from graphene_django.converter before using your model with the TaggableManger field either in Queries or Mutations.

示例:

from graphene_django.converter import convert_django_field
from taggit.managers import TaggableManager

# convert TaggableManager to string representation
@convert_django_field.register(TaggableManager)
def convert_field_to_string(field, registry=None):
    return String(description=field.help_text, required=not field.null)
