使用 django-taggit 时导入错误 add_lazy_relation

Question

I'm trying to add tags functionality to my django application. I want to use taggit app, but when I try to makemigrations I am getting an error:

from django.db.models.fields.related import (add_lazy_relation, ManyToManyRel,
ImportError: cannot import name 'add_lazy_relation'

from taggit.managers import TaggableManager

class Post(models.Model):

    tags = TaggableManager()

I'm using: Django==2.2.8, django-taggit==0.17.1

Answer 1

The error message mentions add_lazy_relation , which was removed in Django 2.0

You are using django-taggit 0.17.1 , which was released in 2015. You can't expect it to support Django 2.2 (released April 2019). Try upgrading to the latest version, currently 1.2.0.
