The Model class does not declare an explicit app_label label and is not in the application at INSTALLED_APPS

I am using sphinx and trying to create documentation for my Django project. I decided to try to document the models first, so in my .rst file I did this

wdland\.models ============== .. automodule:: wdland.models :members: :undoc-members: :show-inheritance:

But get the following errors

 WARNING: /home/fabou/wdlandenvpy3/source/docs/wdland.rst:9: (WARNING/2) autodoc: failed to import module 'wdland.models'; the following exception was raised: Traceback (most recent call last): File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/sphinx/ext/autodoc.py", line 657, in import_object __import__(self.modname) File "/home/fabou/wdlandenvpy3/source/wdland/models.py", line 35, in <module> class Device(models.Model): File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/django/db/models/base.py", line 118, in __new__ "INSTALLED_APPS." % (module, name) RuntimeError: Model class wdland.models.Device doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

After some googling, I found a solution here Django 1.9 app_label resignation warnings see comment from Roman Arseniev on "Jan 11 '16 at 14:54"

I went to my models.py and added a “Meta: app_label class” according to the above message to each class that I had in models.py. This fixed the problem and I was able to create documentation for my models using the sphinx-build script.

Now I wanted to do the same for views.py and did it in my .rst file

 wdland\.views ============= .. automodule:: wdland.views :members: :undoc-members: :show-inheritance:

But when compiling, I get this new similar error, and I could not find a solution for it and did not understand the previous fix for the models.

 WARNING: /home/fabou/wdlandenvpy3/source/docs/wdland.rst:19: (WARNING/2) autodoc: failed to import module 'wdland.views'; the following exception was raised: Traceback (most recent call last): File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/sphinx/ext/autodoc.py", line 657, in import_object __import__(self.modname) File "/home/fabou/wdlandenvpy3/source/wdland/views.py", line 2, in <module> from . import views File "/home/fabou/wdlandenvpy3/source/wdland/views.py", line 19, in <module> from .forms import TicketForm, TicketAmendForm File "/home/fabou/wdlandenvpy3/source/wdland/forms.py", line 1, in <module> from django.contrib.auth.forms import AuthenticationForm File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/django/contrib/auth/forms.py", line 12, in <module> from django.contrib.auth.models import User File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/django/contrib/auth/models.py", line 6, in <module> from django.contrib.contenttypes.models import ContentType File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/django/contrib/contenttypes/models.py", line 139, in <module> class ContentType(models.Model): File "/home/fabou/wdlandenvpy3/lib/python3.5/site-packages/django/db/models/base.py", line 118, in __new__ "INSTALLED_APPS." % (module, name) RuntimeError: Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

Here is the corresponding sphinx configuration

 #!/usr/bin/env python3 # -*- coding: utf-8 -*- import django import os import sphinx_rtd_theme import sys from django.conf import settings sys.path.insert(0, os.path.abspath('../')) settings.configure() django.setup()

wdland is the Django application specified in my INSTALLED_APPS file in the settings file. The sphinx document folder is at the same level as the wdland folder.

Reading such threads in a topic seems to indicate modules that are not yet loaded on invocation. I don’t know how to fix it, how not to test either in the Sphinx or in Django. Any idea on how I can fix this?

Attempting to document urls.py will result in similar errors.

EDIT: Here is the beginning of my view.py

 import datetime from django.core.urlresolvers import reverse from django.db.models import Q from django.http import Http404, HttpResponse from django.template.loader import render_to_string from django.shortcuts import render, HttpResponseRedirect from django.views import generic from random import randint from script.serversnmp import get_ubuntu_snmp, get_esxi_snmp from script.wdlandtools import get_monthly_sess_hour_stats,\ get_monthly_sess_nb_stats,\ get_monthly_ticket_stats,\ get_ticket_category_stats,\ clean_usersession_tbl, update_usertotals_tbl,\ send_email_notification, get_adsl_usage from wdland.models import Device, UserSession, SupportTicket, News, UserTotals,\ SavedUsrSess from .forms import TicketForm, TicketAmendForm from jchart import Chart from jchart.config import Axes, DataSet, rgba

My solution was to create an abstract BaseModel class on your models.py in your application, in your error it could be:

 class BaseModel(models.Model): class Meta: abstract = True # specify this model as an Abstract Model app_label = 'wdland'

And he made all models inherited from this instead of ordinary models. Models.

To solve this problem, I turned to the basics of trying to figure out an error message that says:

The model class wdland.models.Device does not declare an explicit app_label and is not in the application in INSTALLED_APPS.

I also had a bug with another application. Adding the requested "app_label" solved the problem.

I think you do not have django.contrib.contenttypes this in the INSTALLED_APPS django settings. Add it to INSTALLED_APPS django settings
