Django Rest Framework - return authorizatuin token expiry time after registration
I want to return expiry time of auth token after registration. How can i do this? I am also using djano rest knox. serializers.py class Meta: model = User fields = ('id', 'username', 'first_name', 'last_name', 'email') # Register Serializer class RegisterSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('id', 'username', 'first_name', 'last_name', 'email', 'password') extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): user = User.objects.create_user( validated_data['username'], validated_data['email'], validated_data['password'], first_name=self.validated_data['first_name'], last_name=self.validated_data['last_name'],) return user views.py class RegisterAPI(generics.GenericAPIView): serializer_class = RegisterSerializer def post(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.save() return Response({ "user": UserSerializer(user, context=self.get_serializer_context()).data, "token": AuthToken.objects.create(user)[1] }) -
Invoke wrapper for tasks to run with prefixes
I am just starting to look at Invoke and I am having some trouble understanding how the context works and what the task decorator is really doing. My issue is that I am trying to create a wrapper for tasks that tells them prefixes needed. The specific example is I am using this to create a local web app deployment framework with stages. Each stage has its own virtual environment. I am attempting to create a process that allows you to select the stage (done), but then every process that uses that virtualenv and directory needs to be wrapped in context.prefix(f"workon {venv}"). this is where I am having trouble and like any good programmer I am lazy and don't want to be stuck typing this for every commmand.

Django: redirecting a view and using include()
I'm essentially trying to make my URLs more readable by incorporating a slug that is not used for lookup purposes in my views. Previously, I had this in my main URLconf: urls.py path('<int:team_pk>/', TeamDetails.as_view(), name='team_details'), path('<int:team_pk>/', include('tracker.urls', namespace='tracker')), So I had urls like mysite/1/stuff and mysite/1/more/stuff. Then I added a slug field to my Team model. The behavior I want is for any url that only includes a team_pk to be redirected to an expanded URL that incorporates the slug. For example, mysite/1/ should redirect to mysite/1/team_1_slug and mysite/1/stuff should redirect to mysite/1/team_1_slug/stuff. It's this latter behavior that I'm having trouble with. I modified my URLconf to this: path('<int:team_pk>/', TeamRedirectView.as_view(), name='team_details'), path('<int:team_pk>/<slug:team_slug>/', TeamDetails.as_view(), name='team_details_redirected'), path('<int:team_pk>/<slug:team_slug>/', include('tracker.urls', namespace='tracker')), Then I have a simple view to redirect: # views.py class TeamRedirectView(generic.RedirectView): def get_redirect_url(self, *args, **kwargs): team = get_object_or_404(models.Team, pk=self.kwargs['team_pk']) return reverse('team_details_redirected', kwargs={'team_pk': team.pk, 'team_slug': team.slug}) This works for redirecting mysite/1/ to mysite/1/team_1_slug, but any url tag that points to a url inside the tracker app throws a reverse error because I'm not supplying team_slug to the url tag. So I'm basically trying to get my RedirectView to be a little more universal and add this slug to any url without having to … -
Django: how to use helper function to get model object if exists?
I am having this model which is conversations related to ads in classified ads website: class Conversation(models.Model): ad = models.ForeignKey(Ad, on_delete=models.CASCADE) starter = models.ForeignKey(User, related_name='starter', on_delete=models.SET_NULL, null=True) participants = models.ManyToManyField(User) def get_absolute_url(self): return reverse('messages-conversation', kwargs={'pk':self.pk}) def get_if_exists(self, **kwargs): try: return self.objects.get(**kwargs) except self.DoesNotExist: return None in the view I want to check if conversation about that ad already exists with get_if_exists, but I get the errors: If use conversation = Conversation.get_if_exists(ad=ad, starter=request.user) I get Exception Value: name 'self' is not defined If use conversation = Conversation().get_if_exists(ad=ad, starter=request.user) gets: Exception Value: Manager isn't accessible via Conversation instances What I am doing wrong? How to make it so I can use one line in the view to get object if exist and None if doesnt exist? -
Problem in uploading content written using Tiny MCE in Django
I am using Tiny MCE as my Rich Text Editor in my blogging website. But my posts are not getting uploaded when I try to write articles using TinyMCE but getting uploaded while I use a normal text editor. I didn't get suitable answers from google.

Django DRF Post with files and data works in Postman, not Python. No TemporaryUploadedFile
Running a Django App locally, i can use Postman to upload a zip file along with some dict data. Breaking the application in 'def Post()' i can see that Postman's successful upload: request.data = <QueryDict: {'request_id': ['44'], 'status': [' Ready For Review'], 'is_analyzed': ['True'], 'project': ['test value'], 'plate': ['Plate_R0'], 'antigen': ['tuna'], 'experiment_type': ['test'], 'raw_file': [<TemporaryUploadedFile: testfile.zip (application/zip)>]}> Postman offers the following python code to replicate these results in my python script: import requests url = "http://127.0.0.1:8000/api/upload/" payload = {'request_id': '44', 'status': ' Ready For Review', 'is_analyzed': 'True', 'project': 'test value', 'plate': 'Plate_R0', 'antigen': 'tuna', 'experiment_type': 'test'} files = [ ('raw_file', open(r'C:/testfile.zip','rb')) ] headers = { 'Content-Type': 'application/x-www-form-urlencoded' } response = requests.request("POST", url, headers=headers, data = payload, files = files) print(response.text.encode('utf8')) running this code directly and retrieving the request.data (server side) i see the binary representation of the xlsx file is in the object and the payload data is not there (this is the error in the response). How do i get my python script to produce the same server-side object as postman? Specifically how do i upload my data such that the file is represented as: <TemporaryUploadedFile: testfile.zip (application/zip)> Thanks. -
Accessing folders present inside media folder in django
I am new to django. I have created application using it where user can see the videos of their undergoing subjects. I have uploaded multiple videos inside folder name uploadcbse and uploadncert which is present inside media directory. Now I want to display this video in html page but can't access it using {{Media_URL}}{{videofile}}. I am sure it's an error in mentioning path properly because other text fields have been displayed correctly. -
Dashboard using Django or DjangoRestFramework
I was looking at https://robinhood.com/ (they use Django) and noticed that most of their requests are going to https://api.robinhood.com/... I wanted to know the benefits of using an external endpoint like api.robinhood.com instead of just putting all of the methods in one Django project. Does this make sense? Thanks! -

Blueimp Jquery FileUpload - Django-jQuery-File-Uploader-Integration Demo in Django version 3.0.8
As part of a learning process, I'm trying to implement https://github.com/miki725/Django-jQuery-File-Uploader-Integration-demo. I fully expect bugs as this was written in a much earlier version of django. I am running django version 3.0.8. When I attempt to upload a file, I get the following error. I am unable to figure out from research how to fix this bug.

Django unique_for_date with DateField(editable=False)
Django documentation says: If any unique_for_date constraint involves fields that are not part of a ModelForm (for example, if one of the fields is listed in exclude or has editable=False), Model.validate_unique() will skip validation for that particular constraint. The model below sets unique_for_date for a DateField with editable=False, as mentioned above. Based on the excerpt from the documentation above, I would expect the unique_for_date constraint to be skipped during validation. However, the test below passes, showing that validate_unique() does raise a ValidationError due to unique_for_date (using Django 3.0). What am I missing? from django.db import models from django.utils import timezone from django.core.exceptions import ValidationError from django.test import TransactionTestCase class MyModel(models.Model): name = models.CharField(max_length=10, unique_for_date='date') date = models.DateField(editable=False) class MyModelTests(TransactionTestCase): def test_unique_for_date(self): name = 'bird' today = timezone.now().date() MyModel.objects.create(name=name, date=today) my_model_with_duplicate_name_date = MyModel.objects.create( name=name, date=today) with self.assertRaises(ValidationError) as a: my_model_with_duplicate_name_date.validate_unique() self.assertIn('Name must be unique for Date date.', a.exception.messages) -

How to include in django template a reverse url in translation

Displaying image urls during iteration without using the url method
I'm trying to deploy a Django Blog I built to Heroku, but I'm having some issues displaying the thumbnail images of blog posts when rendering my templates. When I first developed the app I was using {{ post.thumbnail.url }} to render the images, and everything was working fine. Now that I've deployed to Heroku I'm swimming in broken links. From [this post][1] I've learned that The "image.url" format in the html does not work on staticfiles/Heroku. That means I would need to use {% static "image url" %} to display the images. The problem is: I'm rendering these posts and their images by iterating over a queryset of posts I'm passing to my templates. Eg: {% for post in most_recent %} <a href="{{ post.get_absolute_url }}"> <div class="item d-flex align-items-center"> <div class="image"><img src="{{ post.thumbnail.url }}" alt="..." class="img-fluid"></div> <div class="title"><strong>{{ post.title }}</strong> <div class="d-flex align-items-center"> <div class="views"><i class="icon-eye"></i>{{ post.view_count }} </div> <div class="comments"><i class="icon-comment"></i>{{ post.comment_count }}</div> </div> </div> </div></a> {% endfor %} How can I get the url of the post's thumbnail image without using the url method? This is what the model looks like: class Post(models.Model): title = models.CharField(max_length=100) overview = models.TextField() timestamp = models.DateTimeField(auto_now_add=True) #comment_count = models.IntegerField(default=0) #view_count = models.IntegerField(default=0) … -

Is there a way to unitary test the arguments passed to Model or Q object?
In my unit tests, I understand how I can mock objects per context, to avoid interacting with any kind of persistent datastore. I can even mock the Q object to test how many times it has been called, which is really useful. But I'm still uncomfortable with the fact that while I'm mocking my interaction with the datastores, I'm still assuming that my code works©, that the datastore (or the ORM in this case) is receiving the data correctly, through the "proper channels" so to speak. Case in point: # code to test def related_stuff(): return Stuff.objects.filter( parent__user__city_name="Las Vegas" ) # more code... # testing above @mock.patch(f"{path_to}.Stuff.objects") def test_related_stuff(stuff_mock): stuff_mock.filter.return_value = stuff_mock stuff_mock.filter.assert_called_once_with(parent__user__city_name="Las Vegas") How can I actually test that the parent__user__city_name lookup pattern is actually correct and wont result in an error? I'm assuming there's no way to test this without touching the datastore, but any opinions are appreciated. -
How do I create three checkouts for subscriptions using Stripe in Python?
I am having a really hard time figuring out Stripe. I created a checkout session using a subscription that I created in the dashboard and have been able to direct towards the checkout. However, I want to have three different buttons that lead to different checkout session, but they all lead to the same checkout (because I don't know how to edit my views.py).
