Can someone help me fix this? first time trying this. AttributeError: type object 'Post' has no attribute 'published'

Question

This is in view.py:

class PostListView(ListView):
    queryset = Post.published.all()
    context_object_name = 'posts'
    paginate_by = 4
    template_name = 'blog/post/list.html'

this is the model in models.py

class PublishedManager(models.Manager):
    def get_queryset(self):
        return super(PublishedManager, self).get_queryset().filter(status='published')

Answer 1

You have created the manager, but not assigned the manager to the model as an attribute called 'published':

class Post(models.Model):
    # other fields
    published = PublishedManager()

See the documentation for further details and caveats.

Answer 2

When you refer Post.published.all() it means you have custom model manager for some field.

Are you sure you have custom manager created? Maybe you meant something like.

Post.objects.filter(for_example_status="pusblished")

Please,provide more details on models structure
