I am using Django 1.9.6. I have, for example, the following model in my models.py file:
class Question(BaseModel):
question_text = models.CharField(max_length=500, unique=True)
class Meta:
verbose_name = 'Question'
verbose_name_plural = 'Questions'
def __unicode__(self):
return (
u"Question id: {}".format(self.id)
)
and in tests.py I am running the following test on it:
class TestQuestionModel(TestCase):
def setUp(self):
Question.objects.create(question_text="What is the airspeed velocity of an unladen swallow?")
def test_simple_questions(self):
simpleQuestion = Question.objects.get(question_text="What is the airspeed velocity of an unladen swallow?")
self.assertEqual(simpleQuestion.question_text, "What is the airspeed velocity of an unladen swallow?")
And I'm using a postgres database. This all works hunky-dory locally.
I understand that I need to convert the output to JUnit XML to run the tests in Bamboo, but I am getting a little stuck. This answer got me 90% of the way there, but I am struggling to figure out the postgres part. The script I am running before the JUnit Parser is as follows:
#installing pip locally
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py --root=${bamboo.build.working.directory}/tmp --ignore-installed
export PATH=${bamboo.build.working.directory}/tmp/usr/local/bin:$PATH
export PYTHONPATH=${bamboo.build.working.directory}/tmp/usr/local/lib/python2.7/dist-packages:$PYTHONPATH
echo Pip is located `which pip`
# setting up virtualenv
pip install --root=${bamboo.build.working.directory}/tmp --ignore-installed virtualenv
virtualenv .
. bin/activate
# get pg_config
apt-get install libpq-dev python-dev
# from the backend/Dockerfile
pip install --no-cache-dir -r requirements.txt
# running tests into JUnit XML format
python ./manage.py test --junitxml=test-reports\results.xml
And I am getting several errors:
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ZV8Jz0/psycopg2/
Traceback (most recent call last):
File "./manage.py", line 6, in

ImportError: No module named django.core.management
Can someone help me overcome this?

Did you install Stripe? if not, try:
pip install stripe
Yet another reason may be that you are using venv but that you installed the module for the wrong version of Python. For example, compare these:
# install to default Python version, which might be, say, 3.10
# ...and then you'll get module not found if you expected to install it to, say, 3.9.
pip install -r requirements.txt
# install the module for 3.9 explicitly
python3.9 -m pip install -r requirements.txt

Django==1.7.1
I am using Django 1.7.1 and I pip installed django-filters to my virtual env at /.virtualenvs/auction2/lib/python2.7/site-packages$
It said it was installed successfully.
So I placed django-filters in installed apps like so:
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'crispy_forms',
'django_filters',
'donations',
)
I ran python manage.py runserver and got this error:
Traceback (most recent call last):
File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
File "/Users/Dani/.virtualenvs/auction2/lib/python2.7/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module
__import__(name)
ImportError: No module named django_filters
It said it installed, but why can't it import it? I have another package, crispy-forms, installed and working. I looked at my site packages on the virtual environment and I saw:
crispy_forms
django
django_braces-1.4.0.dist-info
django_crispy_forms-1.4.0-py2.7.egg-info
django_filters-0.1.0-py2.7.egg-info
easy_install.py
easy_install.pyc
filters
pip
Seeing that it goes in as 'filters' instead of what the documentation says to import it as (django_filters), I thought I'd try changing it to just 'filters' in installed_apps.
I stoped and started the runserver, no problem, so I began building my filter in filter.py:
import django_filters
from donations.models import Donor, Item, Issue
class DonorFilter(django_filters.FilterSet):
class Meta:
model = Donor
fields = {'type':['exact'],'donor':['icontains'],}
def __init__(self, *args, **kwargs):
super(DonorFilter, self).__init__(*args, **kwargs)
self.filters['type'].extra.update(
{'empty_label': 'All Types'})
I stop and start the runserver, no problem. Then I start adding a view and just the import statement at views.py:
from donations.filters import DonorFilter
gives me the same ImportError: No module named django_filters. error.
I tried changing the import in my filters.py to filters rather than django_filters and the errors didn't change. I changed everything back to django_filters (in installed_apps and my filters.py) as the documentation says to do, I get the error global name 'DonorFilter' is not defined when I add the view. Here is the view.py:
def donor_list(request):
f = DonorFilter(request.GET, queryset=Donor.objects.all())
return render_to_response('donations/donor_list', {'filter': f})
That means I need to import the function I created in filters.py? So I add
from donations.filters import DonorFilter to the top of my view.
Then the error is 'module' object has no attribute 'FilterSet'
I can see the FilterSet class in the filters.py file installed in my virtualenv
I noticed there is more development on django-filter, the https://github.com/alex/django-filter page goes up to v0.9.2, but pip installs 0.1.0. Should I be installing it another way (other than pip)?
I'm very new at this and appreciate any help!
My pip version was old, really old. 1.5.6 When I installed my virtual environment it just worked, so I didn't question. Lesson learned! Here is what I did in case it helps someone else...
In the virtual environment, I installed pip as described in the docs:
https://pip.pypa.io/en/stable/installing.html
python get-pip.py This upgraded me to pip 6.1.1
pip install django-filter
pip freeze > requirements.txt
Reading requirements.txt showed I had
django-filter==0.9.2
django-filters==0.1.0
So I uninstalled the older version with pip uninstall django-filters
notice the s on the older version but not on the new one
Really basic stuff but it really tripped me up. Thanks to anyone who took time to look into this!
I also had the same issue. Even after installing django-filters I couldn't import it
ImportError: No module named django_filters
The Django version I'm using is 1.8 and python version is 2.7.x
Solution is to install djangorestframework-filters
pip install djangorestframework-filters
The names are very confusing.
However django-rest-framework-filters is an extension to Django REST framework and Django filter that makes it easy to filter across relationships while Django-filter is a reusable Django application allowing users to declaratively add dynamic QuerySet filtering from URL parameters.
I also encountered this issue installing django-filter==2.2.0
This was my Django version:
Django [required: >=1.11, installed: 2.2]
settings.py:
INSTALLED_APPS = [
# ...
'django_filter',
]
This is the correct installation:
pipenv install django-filter
Hope it helps.
I had a similar issue using django 1.7, djangorestframework==3.2.0 and latest django-filter==0.13.0:
Using DjangoFilterBackend, but django-filter is not installed
cannot import name Expression
I finally fixed it by downgrading django-filter to 0.11.
Now pip freeze looks like this and its working:
Django==1.7
django-filter==0.11.0
djangorestframework==3.2.0
I changed from django_filter to django_filters in installed apps and it was okay.
We install it using: pip install django-filter or in case you are using a virtual environment like pipenv, use pipenv install django-filter .
the above install, adds the latest version of django-filter. Add "==version" to specify the version ( say 0.11.0) you need
In the settings.py under app, ensure it's 'django_filters',
INSTALLED_APPS = [
# ...
'django_filters',
]
I tried all of the above answers and none of them worked for me. I later learnt that the pip script is not installing modules for the interpreter that the python command is using.
SOLUTION:
python -m pip install django-filter
Ensure its django_filters and not django-filters in settings.py. Also keep in find its not django-filter, its django-filters.
But to install it:
pip install django-filter
I removed django_filters in the settings INSTALLED_APPS. this is worked for me
I also experienced the same problem but i realized its because i had installed django-filter when am in the virtual environment.
I tried installing django-filter at the same directory without activating the virtual environment and it worked
I used pip install django-filter
I want to use SASS/SCSS with Django application.
I followed the link https://bitbucket.org/synic/django-sass.
I installed SASS using sudo pip install sass.
When i run Python manage.py runserver,iam getting error as
'sass' is not a valid tag library: Template library sass not found, tried django.templatetags.sass
Can Anyone help me?!
python sass (pip install sass) https://pypi.python.org/pypi/sass is different
from django-sass (https://bitbucket.org/synic/django-sass)
Download django sass from https://bitbucket.org/synic/django-sass after that install and setup as documented .
Have you first installed sass, the ruby app?
$ apt-get install ruby-sass
You'll know if it's done properlly; as type sass on the command line, does sassy things.
Next, I cloned django-sass (from the other answer):
git clone git#bitbucket.org:synic/django-sass.git
Then navigated to the puled folder and installed it.
$ python setup.py install
Initially the installation crashed out:
IOError: [Errno 2] No such file or directory: 'CHANGES.rst'
So I quickly created the file:
touch CHANGES.rst
and ran the install command again.
no problems.
The django-sass-processor package is a great package that lets you easily integrate SASS/SCSS with Django.
Here's a tutorial on how to set up SASS/SCSS with Django.
I've used the package a few times and have been happy with it.
Here is my DIY out of the box solution

I've installed following packages https://github.com/zacharyvoase/django-postgres via pip and virtualenv.:
pip install git+https://github.com/zacharyvoase/django-postgres.git
It was installed succesfully. I used it in my model(As described in its documentaion)
from django.db import models
import django_postgres as pg
USStates = pg.Enum('states_of_the_usa', ['AL', 'WY'])
class Address(pg.CompositeType):
line1 = models.CharField(max_length=100)
line2 = models.CharField(max_length=100, blank=True)
city = models.CharField(max_length=100)
zip_code = models.CharField(max_length=10)
state = USStates()
country = models.CharField(max_length=100)
when I try to sync it via shell, it throws an error:
(virtualenv) user$ python manage.py sync_pgviews
Unknown command: 'sync_pgviews'
Type 'manage.py help' for usage.
Have I left something after installing an app? And is it the correct way to install django new app?
In order for management commands to work, the app has to be added to INSTALLED_APPS. However, a basic problem that you have is that the module doesn't support ENUM yet. Its still a work in progress.
After adding new app:
add app to INSTALLED_APPS in settings.py
run python manage.py syncdb
add urls to urls.py
