I decided to use factory_boy in my simple django application for test purposes.
But I had a problem with simple example. Here is the code of my simple test.
from django.utils import unittest
from ..models import Server, ServerAddress, L2TPServer, serialize_open_vpn_server_json
from factory import django as django_factory
class SshOpenVpnServerFactory(django_factory.DjangoModelFactory):
class Meta:
model = L2TPServer
django_get_or_create = ('name', 'address')
name = 'Hello'
address = 'Nono'
class ServersTestCase(unittest.TestCase):
def test_serialize_server_info(self):
print Server.objects.all()
SshOpenVpnServerFactory.build()
When test-runner executes this test, I get an error:
Traceback (most recent call last):

return target_class.objects
AttributeError: 'NoneType' object has no attribute 'objects'
Where am I wrong? Does factory_boy support django 1.6.5?
The proposed syntax using the Meta class will only be released as part of the (unreleased) Factory Boy 2.4. Use SshOpenVpnServerFactory.FACTORY_FOR instead. Related issue: https://github.com/rbarrois/factory_boy/issues/143

I'm currently trying to have a object oriented schema in Django 2.0 (Python 3.6.3) with a parent class Program and some children classes Snippet and Software. I saw that the model_utils module contains some tools to handle the polymorphism, and tried to replicate the tutorial (http://django-model-utils.readthedocs.io/en/latest/managers.html), here is what it gives in my case:
models.py
from django.db import models
from model_utils.managers import InheritanceManager
class Program(models.Model):
name = models.CharField(max_length=100)
objects = InheritanceManager()
class Snippet(Program):
code = models.TextField()
class Software(Program):
repoLink = models.URLField()
Django shell
>>> from coding.models import Program
>>> programs = Program.objects.select_subclasses()
>>> programs
Traceback (most recent call last):

I don't understand this error and how to fix it, and even don't know if it is a fail in my design or a bad use of the InheritanceManager. So what can be the origin of this error message?
According to the docs, django-model-utils only supports Django 1.8 to 1.10.
I could not load a doc2vec model on my computer and I got the following error. But, when I load that model on other computers, I can use that model.Therefore, I know the model was built correctly.
what should I do.
This is the code:
# coding: utf-8
from gensim.models.doc2vec import Doc2Vec
import gensim.models.doc2vec
from gensim.models.doc2vec import LabeledSentence
import os
import pickle
pth='/home/fatemeh/Step2/input-output/model/iterator'
model= Doc2Vec.load(pth+'/my_model.doc2vec')
This is the error:
Traceback (most recent call last):

I think your model causes the problem. Are you check with same model? I mean build in a same way. please see this page
Whenever I try to construct a string based on self.live_server_url, I get python TypeError messages. For example, I've tried the following string constructions (form 1 & 2 below), but I experience the same TypeError. My desired string is the Live Server URL with "/lists" appended. NOTE: the actual test does succeed to create a server and I can manually access the server, and more specifically, I can manually access the exact URL that I'm trying to build programmatically (e.g. 'http://localhost:8081/lists').
TypeErrors occur with these string constructions.
# FORM 1
lists_live_server_url = '%s%s' % (self.live_server_url, '/lists')
# FORM 2
lists_live_server_url = '{0}{1}'.format(self.live_server_url, '/lists')
self.browser.get(lists_live_server_url)
There is no python error with this form (nothing appended to string), albeit my test fails (as I would expect since it isn't accessing /lists).
self.browser.get(self.live_server_url)
Here is the python error that I'm getting.

Am I unknowingly attempting to modify the live_server_url, which is leading to these TypeErrors? How could I programmatically build a string of live_server_url + "/lists"?
Here is the test that I am attempting...
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from django.test import LiveServerTestCase
class LiveNewVisitorTest(LiveServerTestCase):
def setUp(self):
self.browser = webdriver.Chrome()
self.browser.implicitly_wait(3)
def tearDown(self):
self.browser.close()
def test_can_start_a_list_and_retrieve_it_later(self):
#self.browser.get('http://localhost:8000/lists')
#self.browser.get('http://www.google.com')
#lists_live_server_url = '%s%s' % (self.live_server_url, '/lists')
#lists_live_server_url = '{0}{1}'.format(self.live_server_url, '/lists')
lists_live_server_url = self.live_server_url
self.browser.get(lists_live_server_url)
self.assertIn('To-Do', self.browser.title)
header_text = self.browser.find_element_by_tag_name('h1').text
self.assertIn('To-Do', header_text)
See this discussion on Reddit featuring the same error Traceback.
Basically, this is not a problem with anything within the Selenium tests but rather with your project's static file configuration.
From your question, I believe the key line within the Traceback is:
File "/usr/local/lib/python3.4/site-packages/django/views/static.py", line 54, in serve
fullpath = os.path.join(document_root, newpath)
This line indicates that an unsuccessful os.path.join is being attempted within django.views.static.
Set STATIC_ROOT in your project's settings.pyfile and you should be good.
Use StaticLiveServerTestCase instead may help
INSTALLED_APPS in django is obviously a tuple and therefore immutable.
Why does django-userena try to append a module to it at runtime?
Reference userena/tests/profiles/test.py
from django import test
class ProfileTestCase(test.TestCase):
""" A custom TestCase that loads the profile application for testing purposes """
def _pre_setup(self):
# Add the models to the db.
self._original_installed_apps = list(settings.INSTALLED_APPS)
settings.INSTALLED_APPS.append('userena.tests.profiles')
loading.cache.loaded = False
call_command('syncdb', interactive=False, verbosity=0)
# Call the original method that does the fixtures etc.
super(ProfileTestCase, self)._pre_setup()
def _post_teardown(self):
# Call the original method.
super(ProfileTestCase, self)._post_teardown()
# Restore the settings.
settings.INSTALLED_APPS = self._original_installed_apps
loading.cache.loaded = False
And obviously, when I run the unit tests with userena, I get errors such as:-
======================================================================
ERROR: test_can_view_profile (userena.tests.models.BaseProfileModelTest)
Test if the user can see the profile with three type of users.

settings.INSTALLED_APPS.append('userena.tests.profiles')
AttributeError: 'tuple' object has no attribute 'append'
======================================================================

File "./_thirdparty/django-userena/userena/tests/profiles/test.py", line 11, in _pre_setup
settings.INSTALLED_APPS.append('userena.tests.profiles')
AttributeError: 'tuple' object has no attribute 'append'
How do I solve this problem?
I think this:
self._original_installed_apps = list(settings.INSTALLED_APPS)
settings.INSTALLED_APPS.append('userena.tests.profiles')
Should be
self._original_installed_apps = list(settings.INSTALLED_APPS)
settings.INSTALLED_APPS += ('userena.tests.profiles',)
Looks like a bug to me.
INSTALLED_APPS is a tuple by default but can be changed to a list. The author of that app probably did change that for themselves, wrote the tests and didn't realize that it won't work for people who have INSTALLED_APPS as a tuple. You can most likely fix the problem by changing your settings.INSTALLED_APPS to a list.
Btw, there are better ways how to override settings.
I come across several problems while trying django unittests library. Something strange happens:
I defined the test like this:
from django.core import management
from django.test import TestCase
from django.test.client import Client
from django.core import mail
from django.test.utils import setup_test_environment
from django.contrib.auth.models import User
from django.db import connection
from goserver.models import ActiveList
class GoserverTestCase(TestCase):
#fixtures = ['dat.json']
def setUp(self):
pass
def test_active_list_works(self):
c = Client()
response = c.post('/')
#print response.status_code
self.assertEquals(True, True)
But after the execution of the code it returns following error:
---------------------------------------------------------------------- Unit Test Code Coverage Results

Admin file looks like this:
from goserver.models import ActiveList, Game
from django.contrib import admin
class ActiveListAdmin(admin.ModelAdmin):
list_display = ('user', "is_Bot", "isActive")
admin.site.register(ActiveList, ActiveListAdmin)
admin.site.register(Game)
I run it all this way:
python manage.py test goserver
Also noticed that if I remove lines
c = Client()
response = c.post('/')
from a test case definition, then no error appears
Looking at the traceback, it looks like you have an app called django_test_coverage-0.1 which is importing your app's admin.py.
It is probably importing it from a different location, such as yourproject.yourapp.admin as opposed to yourapp.admin. Since it's technically seen as a different module, it is re-imported and the admin.site.register calls are made again. This causes the AlreadyRegistered error.
My suggestion would be to remove django_test_coverage app (or fix it).
My questions,
I don't see what is base type/class for TestCase - is it Django Test one, or from Unittest?
it is better to use from Django
How are you runnig test? using Django internal test command, by nose, by unittest? By Traceback I thing test command, but I am not quite sure.
What is you definitions for ActiveAdminList and ActiveList? Have you got maybe class Admin in Meta?
I solve this commenting the admin.autodiscover() line in the proye
