After changing a variable in django need to restart the server to update the variable
I'm a beginner in python and django and learned how to send data to the template, but if I'm trying to change the data (variable) while the server is running and reload the page, the data remains old, and to fix that I need to restart the server.

Django User default permission
I want to add permissions (view, add, change, delete) to every user, so I add this meta class in each Model class Meta: default_permissions = ('add', 'change', 'delete', 'view') but when I log in (with new user) to the Django admin site, the user hasn't got the permission yet. Is my approach wrong? -
It's possible to have relationships between models stored in different databases in Django?
I'm currently working on a project where I handle both public and private information, both stored as different models in a common database. I would like to split this database in two, one with the private model objects and another one with the public ones. The thing is, both this models have a ForeignKey relationship with each other, and I've found conflicting answers over the internet about if this relationships can work even if the models are in two different databases. So, is this possible? Is there a better approach for doing this? Just to clarify why I want to do this, I want the project to be open source, therefore the public database should be public, but the sensitive information (users and passwords) should be kept private. -
How to pass a JSON data from React to Django using POST request?
I have a React frontend which has a state variable that contains an array. I want to pass this state variable onClick to my Django's views.py. What I have so far is something like this: App.js const [dataSource, setDataSource] = useState([]); // Where the data is stored in const requestOptions = { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify(dataSource), }; const handleSubmit = () => { fetch("http://localhost:8000/insert", requestOptions); }; <Popconfirm onConfirm={handleSubmit}> <Button>Submit</Button> </Popconfirm> views.py def insert(request): if request.method == 'POST': json_data = request.POST.get() # I'm not sure what should I be putting as a parameter for .get() method return render(request, 'frontend/index.html') urls.py ... urlpatterns = [ ... path('insert/', views.insert), ... ] Am I using the right approach? If it's right, what should I be passing as parameters to the get() method? *P.s. I'm not using DRF for this approach and I'm building the app where Django and React is in one app (not separate) where the frontend is an app of Django. -

Custom Auth Backend
I am looking to create a custom auth backend for my Django project using one field for private key. How to achieve that with removing the "django.contrib.auth.backends.ModelBackend" and replace it with the new auth? Simply, if private key match public key in the database, login that user, else raise error. Note, at the moment all users have public key (RSA) stored in the database, and the private key in stored in the sessions. -

request.get: Temporary failure in name resolution. Cannot use Session()
Inside of a Django web app, I synchronously call an external API using requests. request(url=api_url, method="GET") This gets called roughly 1 or 2 times per minute, and can scale up to 10 times per minute. It mostly works fine, though sometimes I get this error: HTTPSConnectionPool(host='example.com', port=443): Max retries exceeded with url: /api_url/endpoint.json (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f637a4e63a0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')) Now, I understand the correct solution would be to use Session() so that the underlying TCP connection is reused and requests doesn't have to perform a name resolution every time (which, as we've seen, could sometime fail for no avoidable reason). However, Session() would not persist once my Django app has responded to the user. The app works synchronously: I would need an external service that persists the TCP connection to external APIs, only for this purpose... that'd be madness. More simply, I'd like to cache the name resolution somewhere, potentially for days. Is this possible? I have the IP address the api_url resolves to. But I obviously can't query that directly. What's the solution here? -
Best way to declare additional data in Django project
I'm looking for the best practice in order to declare the additional data in a Django project. Imagine I need to store a huge list of choices to use in app1/models.py (I have seen a lot of best practices keep declaring those choices in the body of the models). In another scenario, Imagine I need to keep tens of config data in order to use them in my views.py. Is it common to declare them in the function/class? In my opinion, there would be two common methods in order to do that. (Not sure even recommended at all) Method #1 I can actually keep them all in my settings.py file and access them with importing (like from django.conf import settings). settings.py: ... NBA_TEAMS = ( ("red", "Bulls"), ("yellow", "Lakers"), ... ) Method #2 Keep them all in a file named data.py right next to the settings.py, and try importing it at the end of the settings file like this. settings.py ... try: from .data import NBA_TEAMS, .. except: pass Is there any best practice about this issue? Thank you. -

Force tests to fail if migrations aren't run
I'm blatantly oblivious sometimes, and it led me down a 30 minute blackhole trying to figure out why my constraints weren't being applied in my tests. Turns out I forgot to run makemigrations. Is there a way to configure pytest or django to fail without makemigrations? I know if very clearly warns me Your models have changes that are not yet reflected in a migration, and so won't be applied. Just looking for something a little more obvious/in your face? -

Why does Django add a dollar sign in my URL pattern? (
I spent my entire day trying to fix this bug and I have no idea how to do it. I am trying to create a new markdown file and redirect the user to the new page after submitting the form. I tried to change the URL name, tried to change variable names but nothing works. The problem may be the fact that Django adds a dollar sign in my URL pattern but I am not sure about it because I have tried to give the URL the value of an existing page. I would appreciate a detailed explanation for this problem. my views.py: def entry(request, entry): entryPage = util.get_entry(entry) if entryPage is None: message = messages.warning(request, 'There is not a page with this name.') return render(request, 'encyclopedia/error.html', { 'entryTitle': entry, 'message': message }) else: return render(request, 'encyclopedia/entry.html',{ 'entry': markdowner.convert(entryPage), 'title': entry }) def new(request): if request.method == 'POST': # Get the form form = Post(request.POST) if form.is_valid(): # Clean the form title = form.cleaned_data['title'] lower_title = form.cleaned_data['title'].lower() text = form.cleaned_data['textarea'] entries = util.list_entries() # Check for existing entry for entry in entries: if lower_title == entry.lower(): message = messages.warning(request, "There is already a page with this name.") context = { … -
List & tuple aren't working despite addressing `django.core.excptions.ImproperlyConfigured: The TEMPLATE_DIRS setting must be a list or a tuple` error
I've been hitting a snag with my Django app. Running Python manage.py runserver in my development environment, I get this error: django.core.excptions.ImproperlyConfigured. The TEMPLATE_DIRS setting must be a list or a tuple. After changing TEMPLATE_DIRS to a tuple in settings.py as this TEMPLATE_DIRS = (os.path.join(BASE_DIR, 'templates'),) I got : TypeError('Invalid path type: %s' % type(value).__name__)TypeError: Invalid path type: tuple. I got a similar response when I changed it to a list. Meanwhile, running Python manage.py runserver outside the development environment I got: expected str, bytes or os.PathLike object, not tuple on both times I changed TEMPLATE_DIRS to a list and tuple. I should also add that my template files aren't loading. I get: Using the URLconf defined in myProject.urls, Django tried these URL patterns, in this order: accounts/ admin/ The current path, index/, didn't match any of these Here is the project tree: |_______myApp |______ |______pycache__ | |______migrations | |________init__ | |______admin | |______apps | |______models | |______tests | |______urls | |______views |______myProject | |________init__ | |______asgi | |______settings | |______urls | |______wsgi |______env |______static |______templates |______myApp |______index.html |______signup.html manage.py myProject/urls.py from django.contrib import admin from django.urls import include, path urlpatterns = [ path('accounts/', include('accounts.urls')), path('admin/', admin.site.urls), ] myApp/urls.py from … -
I am having problems with crispy_forms and formsets
I am using django_crispy_forms and have 2 formsets within the main form. The formsets are generating & saving data correctly, except for the first row, the data is never saved. In the source of the page, the first row does not have an instance number and the second row has an instance number of 0. for example, the id of vegetationType for the first row is id_vegetation-prefix-VegetationType, for the second row it is id_vegetation-0-VegetationType. If I remove the formhelper from the html page ({% crispy formset_vegetation%} instead of {% crispy formset_vegetation formset_vegetation.form.helper%}, the formset renders correctly without the extra row at the top, but the rows are not formatted as an inline formset. Does anyone see what I am doing incorrectly? models.py class Landcover(models.Model): Site = models.ForeignKey(Site, on_delete=models.RESTRICT, default=None, blank=True, editable=True, verbose_name='1. Site Name') Recorders = models.ManyToManyField(ProjectStaff, default=None, verbose_name = '2. Recorders(s)', help_text='select all that apply') Date = models.DateField(default=None, verbose_name='3.

How to route to specific viewset methods Django
I've been studying the viewset and router docs for Django and I can't figure out how to set up a route to access the method on a viewset. For example, here is my urls.py: from rest_framework.routers import DefaultRouter from users.views import (UserViewSet, testing) router = DefaultRouter() router.register(r"users", UserViewSet, basename="users") urlpatterns = [ path('testing', testing) ] And then this is my views file in my user directory @csrf_exempt class UserViewSet: def create(self): return JsonResponse({ 'the create endpoint' }) @csrf_exempt def testing(request): return JsonResponse({ "title": "My json res" }) Using postman, I can hit the endpoint example.com/testing and have the json response logged out. However, I try to hit example.com/users/create and I get a 404. I thought the basename propery when registering the viewset with the router would group all of the methods inside that class under that route path and then the methods would all be their own endpoint. Am I thinking about this incorrectly? Any help would be lovely as I am new to Django. I've mostly done Express and Laravel. Thanks!
