Django "settings are not configured" error and cannot define environment variable DJANGO_SETTINGS_MODULE
This error is easy to reproduce. Read many StackOverflow posts and tried multiple methods but did not work. Created new directory named testproject pipenv install django Started new project named test with the django start project script pipenv shell django-admin runserver Error: "django.core.exceptions.ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings." Typed this in ubuntu as suggested in the official django docs: export DJANGO_SETTINGS_MODULE=test.settings django-admin runserver Got a giant line of error followed by ModuleNotFoundError: No module named 'test'. However, if i do django-admin runserver --pythonpath=. --settings="test.settings" the server successfully ran. I know I can just use python manage.py to start the server but my project uses Django cache framework and when I try to access the cache the same settings are not configured error is thrown. Trying to understand what is going on, any help would be greatly appreciated. -

Creating modelform to exclude a field loses "nice" handling of unique contraint
I have a model which includes a 'customer' (fk to User), that I have excluded from a custom form (because the logged in user is already known). The issue I'm having is that I lose the 'nice' form handling for unique constraints once I override the form_valid method to accomodate the excluded field. models.py: class RequestedData(models.Model): customer = models.ForeignKey(Customer, on_delete=models.CASCADE) station = models.ForeignKey(Station, on_delete=models.CASCADE, verbose_name = 'Measurement Station') measurement = models.ForeignKey(Measurement, on_delete=models.CASCADE) class Meta: verbose_name_plural = "Requested Data" constraints = [ models.UniqueConstraint( fields=["customer", "station", "measurement"], name="station-measurement-unique",)] The class view is: class RequestedDataCreate(LoginRequiredMixin, CreateView): model = RequestedData # use overriden form to remove customer from selection form_class = RequestedDataForm success_url = reverse_lazy("requesteddata_list") # overwrite form_valid function to add back in user. def form_valid(self, form): form.instance.customer = Customer.objects.get(user__username=self.request.user) return super().form_valid(form) where you can see I've created a RequestedDataForm to exclude the customer from the form. class RequestedDataForm(ModelForm): class Meta: model = RequestedData exclude = ("customer",) All works well, except when the user enters data in the form that violates the unique constraint. Before I created the custom form to exclude user (i.e. just using the CreateView form), upon violation of the unique constraint a message would appear as shown below, namely, a … -

Filter by distance from coordinates (Django over MariaDB)?
I have a collection of records with latitude & longitude coordinates in my database. Is there a straightforward way to filter for other objects within some specified radius of a given object? Use would be for a method place.get_nearby(rad_km=1.3) -> "QuerySet[Place]" or a function find_nearby(place: Place, rad_km: float) -> "QuerySet[Place]" is fine. If there is a heavily involved solution (lots of new libraries & refactoring necessary), I'll declare this to be out of scope. I currently have a method on my Places to calculate distances between them (both in radians and km), but no way to filter for nearby places. The final use case would be to generate informational tables such as the following: +-------------------------+-----------------------+-----------------------------+ | Northwest Plaza (1.1km) | | NE Corner (0.04km) | +-------------------------+-----------------------+-----------------------------+ | West Street (0.789km) | You are here™ | | +-------------------------+-----------------------+-----------------------------+ | | South Avenue (1.17km) | SW Sunset Building (0.43km) | +-------------------------+-----------------------+-----------------------------+ Additionally, would the best way to determine which square to put an object in be arctan((lat2-lat1)/(lon2-lon1)) (assuming they're reasonably close)? -
Pass JSON data from API to Template in Django

How to deal with Hyphen and Django rest ModelSerializer
I am trying to implement an endpoint to receive email from the mailgun.com API. Basically, when an email is sent to the mailing list, they call your endpoint https://host/messages/ with a POST request. The problem is that they do not use standard REST and some of the keys contain hyphens. This is an example of the request I receive: { 'Date': [ 'Fri, 26 Apr 2013 11:50:29 -0700' ], 'From': [ 'Bob <bob@sandbox9cbe4c2829ed44e98c8ebd0c26129004.mailgun.org>' ], 'Sender': [ 'bob@sandbox9cbe4c2829ed44e98c8ebd0c26129004.mailgun.org' ], 'Subject': [ 'Re: Sample POST request' ], 'To': [ 'Alice <alice@sandbox9cbe4c2829ed44e98c8ebd0c26129004.mailgun.org>' ], 'body-plain': [ 'Hi Alice,\n\nThis is Bob.\n\nI also attached a file.\n\nThanks,\nBob\n\nOn 04/26/2013 11:29 AM, Alice wrote:\n> Hi Bob,\n>\n> This is Alice. How are you doing?\n>\n> Thanks,\n> Alice\n\n' ], I write a serialize and manage to get all fields without hyphens such as From, To, etc. But after hours of trials I cannot manage to get the body-plain. I tried this: class MessageSerializer(serializers.ModelSerializer): Text = serializers.CharField(source='body-plain') class Meta: model = Message fields = ['From', 'To', 'Subject', 'Text'] but I get the error {"Text":["This field is required."]} It seems to me that Django rest is perhaps modifying the keys. Does someone know how to deal with this problem? -
Django TestCase Client Returns URL Without Language Prefix
I have the following unit-test for user password change in my Django app. class LoginRequiredPasswordChangeTests(TestCase): def test_redirection(self): url = reverse('user_accounts:password_change') login_url = reverse('user_accounts:login') print(url) print(login_url) response = self.client.get(url) print(response) self.assertRedirects(response, f'{login_url}?next={url}') Prior to enabling internationalization and switching to i18n patterns in the project's urls.py, the test succeeded. After that it started failing. At the same time, the actual reset functionality works. As you can see, I have inserted a few prints into the test. Here is what they produce. /en/user/password/ /en/user/login/ <HttpResponseRedirect status_code=302, "text/html; charset=utf-8", url="/user/login/?next=/en/user/password/"> The pertinent url patterns for these are # paths for password change path('password/', auth_views.PasswordChangeView.as_view(template_name='user_accounts/password_change.html', success_url = reverse_lazy('user_accounts:password_change_done')), name='password_change'), path('password/done/', auth_views.PasswordChangeDoneView.as_view(template_name='user_accounts/password_change_done.html'), name='password_change_done'), It appears to me that test.client returns a URL without the language prefix. Am I right to think so? Is that expected? How can I fix this? -

Django project-apps: What's your approach about implementing a real database scheme?
I've read articles and posts about what a project and an app is for Django, and basically end up using the typical example of Pool and Users, however a real program generally use a complex relational database, therefore its design gravitates around this RDB; and the eternal conflict raises once again about: which ones to consider an application and which one to consider components of that application? Let's take as an example this RDB (courtesy of Visual Paradigm): I could consider the whole set as an application or to consider every entity as an application, the outlook looks gray. The only thing I'm sure is about this: $ django-admin startproject movie_rental So I wish to learn from the expertise of all of you: What approach would you use to create applications based on this RDB for a Django project? Thanks in advance. -
Django admin automatic reload when foreign key is registered
Does anyone know how does Django notice when a registration tab is closed? For example, when you are creating a certain entry in the database, and it has a Foreign Key (or ManyToMayField and so on) and you click on the plus sing to add an object in another table, and it opens a tab to register this element, and when you save it, it has already been popped up on the options to select on the object you were creating on the first place. I want to know how to do something similar in a regular Django project, but in the template html files. Please, help me.
