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?

Thanks in advance

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.

Example:

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)

I made one version of the Deepak Sood answer what works for me

from graphene import String, List
from taggit.managers import TaggableManager
from graphene_django.converter import convert_django_field

@convert_django_field.register(TaggableManager)
def convert_field_to_string(field, registry=None):
    return List(String, source='get_tags')

And in the tagger model, i create a property names get_tags:

    .
    .
    .
    tags = TaggableManager()

    @property
    def get_tags(self):
        return self.tags.all()

    By the way this should most likely be placed in the class that inherits **graphene_django.DjangoObjectType** . – ImportError Jan 09 '22 at 11:00
  • Another approach to avoid having to add a `get_tags` property ``` return graphene.List( graphene.String, description=field.help_text, required=not field.null, resolver=lambda obj, info: obj.tags.all() ) ``` – pfcodes Nov 22 '22 at 04:17
