Hi Stackoverflow people,
I am working with class based views and for a test site, I followed the documentation to setup the class based views. For a project site (based on the project model below), I just want to create a quick CRUD application for the simple project model below.
models.py
class Project(models.Manager):
name = models.CharField(_('Name of the Project'), max_length = 100,)
slug = models.SlugField(max_length=100,)
...
views.py
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from django.core.urlresolvers import reverse_lazy
from project.models import Project
class ProjectCreate(CreateView):
model = Project
class ProjectUpdate(UpdateView):
model = Project
When I now load \project\add
, which should call the ProjectCreate
class, I get the following error:
type object 'Project' has no attribute '_meta'
I do not understand why. The model class normally does not require meta information. In other class based projects, I did not encounter this problem.
Thank you for your suggestions!

Change:
class Project(models.Manager)
to:
class Project(models.Model)
because models.Model
is actual class you must extend to create custom models, and managers are actually used to override database operations models are involved in.
