Python manage.py runserver in Docker container not working
Inside my Docker container, in the root folder of my Django application, I activate a virtual environment, and run python manage.py runserver. I have exposed the ports 80 and 443 for the container, and at first glance it appears to be running >>> docker run -it <container> >>> cd .virtualenv >>> source bin/activate >>> cd .. >>> python manage.py runserver System check identified no issues (0 silenced). February 20, 2018 - 20:32:08 Django version 1.11.6, using settings 'sesttings.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C. When I go to http://:8000 though the site can't be accessed, it just sits there and loads forever. I checked the logs using docker logs container_id, but there isn't anything in there. -
Upon stripe customer creation save Customer model on server
The stripe customer is being successfully created on stripes servers but I need a representation on my server so I created the Customer model all it has is the user_id and the stripe_id. Heres the code I have been trying but it does not work.. I think the problem is with retrieving the actual stripe id for that particular user.. # Create stripe customer stripe.Customer.create() new_customer = Customer( user=request.user, stripe_id=id, ) new_customer.save() This snippet of code is inside the user registration view, and it runs after the user is authenticated and logged in So what appears in the stripe_id field is: <built-in function id> -
Nginx serving Django in subdirectory - admin login is redirecting
I have to serve a Django app from a subdirectory (hostname/service/). So far I'm able to get to the Admin Login prompt (hostname/service/admin/login/), but after successfully logging in I'm redirected to (hostname/admin/login/) and get a 404. How can I keep the correct subdirectory and get inside the Admin panel? Here's the nginx.conf server block: server { listen 80; root /usr/share/nginx/html/; charset utf-8; location /service { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://djangoapp:8000/; proxy_set_header X-Real-IP $remote_addr; } location /static { alias /usr/src/app/static; } } -
Why do I lose connectivity to my SQL server when running through Apache?
I am trying to deploy my django project on my company LAN. I am able to get the site working, however, I lose connectivity to my Microsoft SQL Server when I run site through apache. Everything works fine in the development environment. I suspect it I am losing windows authentication when I work through the apache server. This is what my db settings are in my settings.py files: 'mosaiq': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'MOSAIQ', 'USER': '', 'PASSWORD': '', 'HOST': 'HHCMOSAIQ01T', 'PORT': '', 'OPTIONS': {'driver': 'ODBC Driver 11 for SQL Server', }, Any ideas how to connect to my sql server using windows authentication or does my problem lie elsewhere? -

multiple paginations in Django not working, getting redirected
I am struggling with this for a while now and I came close to something. I have four models bound to each other by foreign keys in this order: Faculty > Department > StudyProgramme > Courses. I created pagination with search for all of my courses. Now I wanted to create pagination for courses that belong to a specific faculty only. For example, I have a total of 3 courses, from which 2 belong to Informatics faculty and 1 belongs to Medicine faculty, and for each of those I need pagination by 1 course per page. After a lot of tries, I thought of using faculties id's as a way to make individual pagination, but no success.. All courses of a faculty get displayed, instead of just 1, and if I click next, I get redirected to the pagination of all courses. I don't know how to fix this: @login_required def index(request): query_list = Course.objects.all() query = request.GET.get('q') if query: query_list = query_list.filter(Q(name__icontains=query)) paginator = Paginator(query_list, 1) page = request.GET.get('page') faculty_id = request.GET.get('faculty_id') courses_to_display = None try: courses = paginator.page(page) except PageNotAnInteger: courses = paginator.page(1) except EmptyPage: courses = paginator.page(paginator.num_pages) if not faculty_id: courses_to_display = courses faculties = Faculty.objects.all() for … -

Trouble rendering Images through Django templates using static tags and view.py request
I am trying to dynamically add images to my web page using Django templates. If is add the image name directly, the image is on the web page as expected: {% block content %} {% load staticfiles %} <img id='productImage' src="{% static 'buylist/img/images/image name.jpg' %}"> {% endblock %} instead of passing the name of the file directly, I want to pass the file name using my the name of the product in my database like: <img id='productImage' src="{% static 'buylist/img/images/{{product.name}}.jpg' %}"> But I guess I can't use template tags inside of static tags? When I do it this way and inspect the element on the webpage, I see that it rendered{{product.name}} as pure text, so of course it didn't find the image. I also tried including the file name in my database directly as an attribute of my product like: <img id='productImage' src="{% static 'buylist/img/images/{{product.image}}' %}"> There was still no image where I would expect one, but when I inspected the element on the page it had the correct filename image name.jpg. I don't know too much about html, but this led me to believe there was some sort of problem with my directory settings. I tried including in my … -

Django nested dictionary to display in templates
I have a dictionary that looks like this dict = { 'https://i.redd.it/4d87ifm2mch01.jpg': 'https://reddit.com/7yv1d8', 'https://i.redd.it/ru0bq0jpr9h01.jpg': 'https://reddit.com/7ys0l3', 'videos': {'https://gfycat.com/ifr/selfassuredinfinitehochstettersfrog'},.. } 'videos' stores values as a set so i wont have duplicate urls and it's convenient. But i faced a problem, how can I display the nested dictionary in templates? I have it like that for now {% for keys,values in data.items%} {% for i,j in keys.items %} <iframe src='{{j}}' frameborder='0' scrolling='no' allowfullscreen width='300' height='300'></iframe> <a class="thumbnail" href="{{values}}"><img src="{{keys}}" width="100px" height="66px" border="1" /><span><img src="{{keys}}" /><br />whatever.</span></a> <br /> I want the 'videos' values to be stored in the <iframe> and others as an image. -
Testing and mocking a threaded function within a view
I'm trying to unit test a function that I run threaded within a view. Whenever I try to mock it, it always goes to the original function, no the mocked function. The code I'm testing, from the view module: def restart_process(request): batch_name = request.POST.get("batch_name", "") if batch_name: try: batch = models.Batch.objects.get(num=batch_name) except models.Batch.DoesNotExist: logger.warning("Trying to restart a batch that does not exist: " + batch_name) return HttpResponse(404) else: logger.info(batch_name + " restarted") try: t = threading.Thread(target=restart_from_last_completed_state, args=(batch,)) t.daemon = True t.start() except RuntimeError: return HttpResponse(500, "Threading error") return HttpResponse(200) else: return HttpResponse(400) The test function: class ThreadTestCases(TransactionTestCase): def test_restart_process(self): client = Client() mock_restart_from_last_completed_state = mock.Mock() with mock.patch("processapp.views.restart_from_last_completed_state", mock_restart_from_last_completed_state): response = client.post('/batch/restart/', {"batch_name": "BATCH555"}) self.assertEqual(response.status_code, 200) mock_restart_from_last_completed_state.assert_called_once() The URL: url(r'^batch/restart/$', views.restart_from_last_completed_state, name="restart_batch"), I always get this error: ValueError: The view processapp.processing.process_runner.restart_from_last_completed_state didn't return an HttpResponse object. It returned None instead. I put a print command in the original function (restart_from_last_completed_state) and it always runs so the mocking does not take place. The error seems to take the function as a view although it is not. I'm not sure where the error is, the threading, testing, something else? -

How to create a dynamic model-form?
I'm new to Django and I'm trying to write a project where employers can post job vacancies. I want to be able to save the job description as a model using a model-form but I also want to allow the user to specify how many requirements there are for a job. So one job might specify 4 job requirements while another might specify 6. So saved models will vary depending on how much requirements were specified. Is there anyway to create a dynamic model-form where the user can specify how many fields there are in the form and model? I've been researching this for a while but yet to find a simple explanation. -

django checkbox unchecked despite initial=True
I have a Django form containing a boolean field, "reduction." The field has an initial value of True (i.e. I want the corresponding checkbox to render as checked). My problem is that this doesn't happen. When the form first renders, the checkbox is unchecked. Searching for this topic yields a ton of issues related to the value of the checkbox on submit, and how it doesn't send anything if unchecked, etc. But I can't figure out why Django isn't initially checking this box. I've verified that the value of the field in the form is indeed true when the form is passed to the template from the view. Any ideas? The Form: class RunParamsForm(Form): fluid_present = BooleanField(widget=HiddenInput, required=False) solid_init_present = BooleanField(widget=HiddenInput, required=False) solid_sim_present = BooleanField(widget=HiddenInput, required=False) solid_present = BooleanField(widget=HiddenInput, required=False) load_map_present = BooleanField(widget=HiddenInput, required=False) scallop_map_present = BooleanField(widget=HiddenInput, required=False) fluid_endtim_units = CharField(widget=TextInput(attrs={'class': 'units', 'readonly': 'readonly'})) solid_init_drterm_units = CharField(widget=TextInput(attrs={'class': 'units', 'readonly': 'readonly'})) solid_sim_endtim_units = CharField(widget=TextInput(attrs={'class': 'units', 'readonly': 'readonly'})) steps = CharField(widget=HiddenInput) reduction = BooleanField(initial=True, required=False) The relevant html: <!-- REDUCTION BLOCK --> <div class="block1"> <div class="queueRunHeading"> Other </div> <div class="fieldWrapper"> <label for="{{ form.reduction.id_for_label }}"> 1-Dimensional Reduction </label> {{ form.reduction }} <span class="errorlist"> {{ form.reduction.errors.as_text }} </span> </div> </div> -

Optimise Django query with large subquery
I have a database containing Profile and Relationship models. I haven't explicitly linked them in the models (because they are third party IDs and they may not yet exist in both tables), but the source and target fields map to one or more Profile objects via the id field: class Profile(models.Model): id = models.BigIntegerField(primary_key=True) handle = models.CharField(max_length=100) class Relationship(models.Model): id = models.AutoField(primary_key=True) source = models.BigIntegerField(db_index=True) target = models.BigIntegerField(db_index=True) My query needs to get a list of 100 values from the Relationship.source column which don't yet exist as a Profile.id. This list will then be used to collect the necessary data from the third party. The query below works, but as the table grows (10m+), the SubQuery is getting very large and slow. Any recommendations for how to optimise this? Backend is PostgreSQL but I'd like to use native Django ORM if possible. user = Profile.objects.get(handle="philsheard") qs_existing_profiles = Profiles.objects.all() rels = TwitterRelationship.objects.filter( target=user.id, ).exclude( source__in=Subquery(qs_existing_profiles.values("id")) ).values_list( "source", flat=True ) Thanks in advance for any advice! -

Django Deploy to Heroku "Six" / "django-appconf" issue
I am a complete beginner, but I have created a small website using Python / Django with the help of django-cookiecutter, including the deploy to Heroku instructions. I am in the process of deploying it for the first time to Heroku, however, the build is failing at the point in which it is running setup.py install for django-appconf, suggesting that it is due to the fact that Heroku already has the "Six" package. The error message I am receiving is as follows: Running setup.py install for django-appconf: finished with status 'error' Complete output from command /app/.heroku/python/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-tzjhtkga/django-appconf/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-y2i8uuc4-record/install-record.txt --single-version-externally-managed --compile --without-c-extensions: usage: -c [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: -c --help [cmd1 cmd2 ...] or: -c --help-commands or: -c cmd --help error: option --without-c-extensions not recognized ---------------------------------------- Command "/app/.heroku/python/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-tzjhtkga/django-appconf/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-y2i8uuc4-record/install-record.txt --single-version-externally-managed --compile --without-c-extensions" failed with error code 1 in /tmp/pip-build-tzjhtkga/django-appconf/ !
