how to properly do aggregate functions in django ORM for a case where a reference in a table is more than once
I have a table in django. Everytime a user leaves a tip a entry in that table is created. I am trying to create a query that does the following. gets the user reference to the FK user of a user. but only once. So even if there are more than 1 rows with that user FK (because they left more than one tip) I still only want it once. then the total number of tips a user has left. This is why I only want the user FK object once, regardless of how many times it shows in the table. As the total number of tips is to determine the number of tips a user has left. The total dollar amount of all the tips they have left. so if they left a tip of $5 $15 $ 25 the total amount in this field would be $45 Here is my query set and my serializer and my payload. the shochattotalminutes and totalmoney are unrelated to this question. userlist = ShoChatEntityShoChatTips.objects.annotate( numberofshochats=Count('user')).annotate(totaltips=Sum('tipamount')).filter(shochatentity= shochatentity).order_by('totaltips') serializeduserlist = ContentCreatorTopTippersSerializer(userlist, many=True) payload = { 'userList': serializeduserlist.data, 'shochattotalminutes': shochattotalminutes, 'totalmoney': totalmoney } return Response(payload) however please notice the output in the screen shot below. … -
How to access one to many field on django admin page

Which is a better way to enforce OneToOne Relationship in Django?
Were wondering which would be the effective way to enforce OneToOne relationship in Django. Here is what we have encountered and wanted opinion. class Address(models.Model): phone = models.OneToOneField(Phone, related_name='phoneNumber') class Phone (models.Model): phone = models.PositiveIntegerField(min_length=9) the other was using ForeignKey with unique_together - class Phone(models.Model): address = models.ForeignKey(Address, related_name='phoneAddress',on_delete=models.CASCADE) phone = models.PositiveIntegerField(min_length=9) class Meta: unique_together = ['phone','address',] or by creating a Subclass - class Address(models.Model): .... class Phone (Address): phone = models.PositiveIntegerField(min_length=9) your expertise and insights appreciated. Cheers! -

Have django embed url into either image or video tag in the admin list display
I currently have a admin.py file that looks like this from django.contrib import admin from remover.models import FileUrlVal class FileAdmin(admin.ModelAdmin): list_display = ( 'user', 'ip_address', 'value', 'total_credits', 'total_frames', 'preview' ) admin.site.register(FileUrlVal, FileAdmin) With the FileUrlVal model looking like this class FileUrlVal(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.SET_NULL, null=True) ip_address = models.GenericIPAddressField(null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) value = models.CharField(max_length=1000, db_index=True) job_name = models.ForeignKey(Dicty, db_index=True, on_delete=models.CASCADE) total_frames = models.IntegerField(default=0) total_credits = models.IntegerField(default=0) content_type = models.CharField(max_length=240, db_index=True, default='') preview = models.CharField(max_length=240, db_index=True, default='') This all works fine.

Fetching data from an api and adding to a database in Django
I'm working on a project where I need to update values based on whether a user adds/deletes them. But, the original data is from an api, and I want to store that in a Django database. How do I do that without repeatedly making calls to the api? In other words, I just want to include the data from the api in my database in the beginning, and then modify it accordingly based on what the user decides to add/delete in the future without having to fetch that api over and over to check if its data exists in the database or not as that is unnecessary. -

How can I fix KeyError: 'ariadne_jwt'?

Getting text of HTML element and passing it to django view using AJAX
I have the following paragraph: <p>{{donation.pk}}</p>. I want to pass the value of the paragraph into the view bellow as a pk def acceptdonation(request, pk): #the `pk` should be the `pk` of the `p` element deleteitem = Donation.objects.filter(id = pk) deleteitem.delete() return redirect('/dashboard/') I did research, and heard that you need to use AJAX.

Change response to JsonResponse in Class-based view
I'm using curl to submit form data to my website. curl -F some_file=@file.txt -F name=test_01 https://localhost:8000 It's not an API but I have a requirement for a single endpoint that behaves as an API. I'm a little out of my depth here, so I'm hoping someone can help me. I've got the model set up and working and the CreateView, as well: class CreateFile(CreateView): model = SomeFile fields = ['name', 'some_file', . . .] When I send a POST request with curl as above to the specified URL (/file/request), the object is created in the DB and I get a response (set to /thanks now which is a generic templated HTML rendered file). But since a non-browser will be sending this request, I was hoping to respond with some JSON. Maybe with the object's name, status, etc. I've tried a few things with mixed results... For example, if I use View instead of CreateView, I can return JSON but I really like the ease and convenience of the CreateView CBV, so I'm hoping I can do what I want this way. How can I do this? -
Using Django tests on model validation, how to test that a value does not raise a validation error
I know that I can check if a validation error will be raised like so: ` def test_validate_fee_range(self): test = Foo.objects.get(name="T1") test.full_clean() test.fee = 105 # raise Validation error for value less than 0 and greater than 100 self.assertRaises(ValidationError, test.full_clean)` For completeness I want to test that values between 0 and 100 do not raise a ValidationError. How do I do this? -
Django DRF, how to properly register custom URL patterns with DRF actions
Background I have a ModelViewSet that defines several custom actions. I am using the default router in my urls.py to register the URLs. Right now, my views use the default created routes like ^images/$, ^images/{pk}/$. In order for users to use the API using resource names with which they are familiar, I have adapted the viewset to accept multiple parameters from the URL, using the MultipleFieldLookupMixin strategy described in the docs to allow for the pattern images/{registry_host}/{repository_name}/{tag_name}. I've created the get_object method in my viewset like so: class ImageViewSet(viewsets.ModelViewSet): ... def get_object(self): special_lookup_kwargs = ['registry_host', 'repository_name', 'tag_name'] if all(arg in self.kwargs for arg in special_lookup_kwargs): # detected the custom URL pattern; return the specified object return Image.objects.from_special_lookup(**self.kwargs) else: # must have received pk instead; delegate to superclass return super().get_object() I've also added a new URL path pattern for this: urls.py router = routers.DefaultRouter() router.register(r'images', views.ImageViewSet) # register other viewsets ... urlpatterns = [ ..., path('^images/<str:registry_host>/<path:repository_name>/<str:tag_name>', views.ImageViewSet.as_view({'get': 'retrieve',})), path('', include(router.urls)), ] Problem The above all works as intended, however, I also have some extra actions in this model viewset: @action(detail=True, methods=['GET']) def bases(self, request, pk=None): ... @action(detail=True, methods=['GET']) def another_action(...): ... # and so on With the default patterns registered by … -

Why is my django project only working properly on Chrome but not Edge nor Safari?
I was working on my landing page for my project and I was doing it all in Chrome but then I wanted open it in Edge and it does not seem like it can find my static files. My page looks all messy in Edge and I get the following in the terminal: On Crome there is no error and that is the weird part for me. Here is the structure of my files: I see it cannot find the files and django has a way of using static files and the way I called each static file is <link href="{%static 'vendor/bootstrap/css/bootstrap.min.css'%}" rel="stylesheet" /> or <script src="{%static 'vendor/bootstrap/js/bootstrap.bundle.min.js'%}"></script>. I have no idea how I got here or if I am doing something wrong so any feedback would be appreciated. -

form doesnt dave, but adds a weird string into the url
following a Django tutorial, i coded the following html file that takes a form filled by a user and adds it to the database as an object (the form is a bunch of attributes of a class) {% block content %} <form> <form method="POST"> {% csrf_token %} {{ form.as_p }} <input type='submit' value = 'save' /> </form> {% endblock %} instead of saving the form to the database, it adds a weird string to the url (pasted below). this happened to the guy in the tutorial, but it was fixed after he added the <form method="POST"> {% csrf_token %} what is this "error", and how can i deal with it? also, what can i do if it happens in the future? there's no real error, the server goes on fine, so there's no traceback/error message to show. i made sure the form.as_p is a real variable, and that there's no typos in the variables or tags relative to the tutorial. only problem i can think of is the change in versions - the tutorial is in Django 2.0.7 and i am on 3.2.5, but the csrf_token is still valid according to what i saw in the docs. added to the … -
