passing session in forms.py in django
I'm working on django project, in which I'm using model as form to generate an image upload page. The problem is there's a foreign key referring to user's profile table which fetches a list of users in a drop down menu. I figured i need to use the session value from logged in user but so far I haven't been able to pass the session through forms. Of course, I've tried couple of solutions found on similar questions but those options didn't work for me here's the code: forms : class ImageForm(forms.ModelForm): class Meta: model = ImageMedia fields = ['id', 'Image', 'ImageTitle', 'ImageContext', 'Uploader'] labels = {'Image' : 'Select Image', 'Image Context' : 'Image Context'} Models : class ImageMedia(models.Model): id = models.AutoField(primary_key = True) Image = models.ImageField(verbose_name="Image Name", upload_to = "ImageSet") UploadDate = models.DateTimeField(verbose_name="Date and time uploaded", auto_now_add=True) Uploader = models.ForeignKey(UserProfile, on_delete=models.CASCADE, null=False) ImageTitle = models.CharField(verbose_name="Image Title", null=False, max_length=100) ImageContext = models.CharField(verbose_name="Image Context", max_length=500, null=True) def __str__(self): return self.ImageTitle upload template <body> <div class="container"> <center><div class="card" style="width: 28rem;"> <div class="py-5 text-center bg-secondary text-white"> <div class="card-header"> <h1 class="mb-3">Upload Image</h1> </div> <form name="UploadForm" method="POST" enctype="multipart/form-data"> {% csrf_token %} {% comment %} {{form.Image}} {{form.ImageTitle}} {{form.Uploader.as_hidden}} {{form.ImageContext}} {% endcomment %} {{form.as_p}} <input type="submit" id="submit" … -
Best way to convert Django ORM query to GraphQL
So I have this webapp, that the frontend side allows the user to build dashboards which in-turn create a GraphQL query. This query is sent the the Backend (Django) and all the backend does is route this request to some external DB that handles the GraphQL and returns a response. The issue: I have a complex logic in the backend, that knows how to create a Django ORM query (Q) per each request, which I would like to combine with the GraphQL query. Basically im trying to convert a Django Q (django.db.models.query_utils.Q) into a GraphQL filter section. Is there a way to do it? Maybe with a different generic lang than GraphQL? or Do I have to resort to write something myself -
Submitting Bulk Forms In Django
I have 5 different forms in forms.py; the forms are all based off of 1 model. The 5 forms are all displayed on the same html page, so as to allow the user to create or register 5 objects into the DB with 1 single button click. In the future, I might need to submit 50 forms in a single click. If I were to do this based on the existing code, I would probably need 50 forms in forms.py and repeat the registration logic in views.py for 50 times. Is there a more efficient way to do this? views.py def register(request): form1 = DetailsForm1() form2 = DetailsForm2() form3 = DetailsForm3() form4 = DetailsForm4() form5 = DetailsForm5() if request.method == "POST": form1 = DetailsForm1(request.POST) if form1.is_valid(): form1.save() form2 = DetailsForm2(request.POST) if form2.is_valid(): form2.save() form3 = DetailsForm3(request.POST) if form3.is_valid(): form3.save() form4 = DetailsForm3(request.POST) if form3.is_valid(): form3.save() form5 = DetailsForm5(request.POST) if form5.is_valid(): form5.save() return render(request, "app/registration_completed.html") context = { "form1": form1, "form2": form2, "form3": form3, "form4": form4, "form5": form5 } return render(request, "app/register.html", context) forms.py class DetailsForm1(forms.ModelForm): class Meta: model = Property fields = ( 'owner', 'address', 'postcode', ) class DetailsForm2(forms.ModelForm): class Meta: model = Property fields = ( 'owner', 'address', 'postcode', … -
Web API that itself sends data to client on availability
I am currently working with Django but I am stuck as I don't know if I am pursuing the right model given the nature of my application. Problem Statement: I have to make a REST API for a client such that whenever I get a trigger for a new entry/entries in my Database I have to send those to the client which is supposed to listen to a URL and has asked for data only once and now is open to receive data whenever available to him. It is not sending a GET request now and then. There will be different endpoints of the APIs. One is where I provide him all the new data available to me and in other where it asks for specific data (ex: '/myAPI/givemethis') I can easily implement the second requirement as it is a simple request-response case. I am not sure how to send him data that too on availability without him making a repeated request as client. It appears a Publisher-Subscriber model is better suited for my use case but I don't know how to implement it on Django. I bumped into several concepts like StreamingServices and MQTT but I am not sure … -
Django statics returns 404 error in cPanel Passenger
I used cPanel and deployed a Django application on my server using passenger_wsgi.py. The problem is when I'm trying to access static files (like admin CSS file: static/admin/css/base.css) I'm facing with 404 error.

Django rest framework URL pattern of CRUD operation in single GenericAPIView class
I have been creating a class view with GenericAPIView in the Django rest framework. and define their URLs but on Django swagger, every URL shows all methods. #views.py class AmenitiesView(ListModelMixin, RetrieveModelMixin, CreateModelMixin, DestroyModelMixin, UpdateModelMixin, GenericAPIView): serializer_class = AmenitiesSerializer queryset = Amenities.objects.all() def get(self, request, *args, **kwargs): many, queryset = True, self.filter_queryset(self.get_queryset()) if 'pk' in kwargs and kwargs['pk']: many, queryset = False, self.get_object() serializer = self.get_serializer(queryset, many=many) return Response({"data": serializer.data, "message": "Successfully Get Amenities", "isSuccess": True, "status": 200}, status=200) def post(self, request, *args, **kwargs): return self.create(request, *args, **kwargs) def put(self, request, *args, **kwargs): return self.update(request, *args, **kwargs) def delete(self, request, *args, **kwargs): return self.destroy(request, *args, **kwargs) #urls.py urlpatterns = [ path('amenities/get/', AmenitiesView.as_view()), path('amenities/get/<int:pk>/', AmenitiesView.as_view()), path('amenities/create/', AmenitiesView.as_view()), path('amenities/edit/<int:pk>/', AmenitiesView.as_view()), path('amenities/delete/<int:pk>/', AmenitiesView.as_view()), ] how to define URL with the method, like if 'amenities/get/' is URL so on swagger will show only get method and if URL is 'amenities/create/' so only post method shown on this url. -
subprocess.call() doesn't throw and error when file is not found
I'm trying to run a python script from a Django web service and I'm using the subprocess.call() method and I've put it in a try except block because I need to get the error when something is wrong. I discovered that when the path to the script is not valid is not raising an error it's only displaying it on the console, but I need it to be thrown so I can catch it in the except block. Here is my code. try: row = exec_SQL(f"SELECT [ID], [ProjectPath], [MainFileName] FROM [dbo].[WebserviceInfo] WHERE ProjectName='{project}'") command = f'python {row[1]}\{row[2]} {model} {scenario}' subprocess.call(command, shell=True) except Exception as e: error_message = str(e) This is the path to the file + some arguments that I need. f'python {row[1]}\{row[2]} {model} {scenario} Thanks in advance for your help. -

When to use Django instead of Streamlit
We are devloping various web applications for design and optimization of energy infrastructure. We have been working in Django for some time now. I just became aware of Streamlit.

Combining javascript search with dropdown filter
I have a working code with a live javascript search where I can search in a table for a user by either their first and last name or one of them. I also have a working dropdown filter, where you can choose a rank, which will only show the users with that specific rank. The problem is, they don't combine --> If I do a search and then select the rank, it shows all users with that rank, and it doesn't use the search. It also doesn't work the other way. Does anyone have an idea how I can combine the two filters? I work in Django, so my java and HTML are on the same page. I left out the sort function because it's not relevant for my question.

limiting __in lookup in django
i have are question about "__in" lookup in Django ORM.

All i need to understand is how to limit "__in" expression in Django to get only last value as in example above. Is it possible? -

AnonymousUser automatically created for TestCase
I'm encountering a situation where an anonymous user is automatically created upon constructing a TestCase which is not expected nor desired. The example test case that is posted below is not the sole test case experiencing this behavior. A custom User model has been created for my project, but I'm not sure if that has inadvertently done something to cause this. In python manage.py shell, I queried all users with get_user_model().objects.all(); within the queryset there was an instance of <User: AnonymousUser>. That was deleted as I closed/re-opened the shell and checked the admin as well. To specify what database I'm using for testing I'm using the built in test database Django provides with SQLite What would be causing the testcase to automatically populating with an AnonymousUser? from django.test import TestCase class TestViewUserQuestionsPostedPage(TestCase): @classmethod def setUpTestData(cls): cls.viewed_user = get_user_model().objects.create_user("ItsYou") testcase_users = get_user_model().objects.all() request = RequestFactory().get(reverse("authors:profile", kwargs={'id': 1})) cls.view = UserProfilePage() cls.view.setup(request, id=2) cls.view_context = cls.view.get_context_data() def test_viewed_profile_of_user(self): self.assertIsInstance(self.view, Page) self.assertIn('user', self.view_context) self.assertEqual(self.view_context['object'], self.viewed_user) (Pdb) testcase_users = get_user_model().objects.all() (Pdb) testcase_users <QuerySet [<User: AnonymousUser>, <User: ItsYou>]> from django.contrib.auth.models import AbstractUser class User(AbstractUser): username = CharField( unique=True, max_length=16, error_messages={ "unique": "Username not available" } )
