I am writing custom template tag, and the error occurs that "Unresolved reference 'models'" the following is my blog_tags.py.
from django import template
from .models import Post
register = template.Library()
@register.simple_tag
def total_posts():
return Post.published.count()
And my directory tree is as followed
blog/
__init__.py
models.py
...
templatetags/
__init__.py
blog_tags.py
And i do have a Post class in my Models.
And when i click the prompt by pycharm "install package Post", after finishing installed it, the error disappear. I wonder do i have to do the same, which is install the package by the IDE, every time when i want to write a custom tag evolved with class in my Models?
If I'm interpreting your project structure correctly, your models module is located in a parent package relative to blog_tags. Accessing .models would try to find the module inside your templatetags package.
Try to change your import to this instead:
from ..models import Post
As this is Django and as in Django circular imports can be an issue, consider dynamically loading the model:
for django 1.7+ use the application registry:
from django.apps import apps
Post = apps.get_model('blog', 'Post')
for earlier versions:
from django.db.models.loading import get_model
Post = get_model('blog', 'Post')
Note: This only works if 'blog' is an installed app.
import your models with app namespace instead of relative import, so that the standard structure is maintained.
from django import template
# blog is your app name
from blog.models import Post
register = template.Library()
@register.simple_tag
def total_posts():
return Post.published.count()
