Dynamically filtering fields in formset
I have a view: class SummaryListView(ListView): model = MyModel MyModelFormSet = modelformset_factory( MyModel, fields=('field1', ), formset=BaseMyModelFormSet, ) def get_context_data(self, *args, **kwargs): context = super().get_context_data(*args, **kwargs) fields = get_fields(self) formset = self.MyModelFormSet(request=self.request) context['formset '] = formset return context def post(self, request, *args, **kwargs): formset = self.MyModelFormSet(request.POST, request=request) if formset.is_valid(): formset.save() return redirect('') I want to pass MyModelFormSet a list of fields to render which I generate with a function get_fields() which takes self as an argument. Now, I can place MyModelFormSet inside get_context_data, but then how do I access it from post? Or can I pass MyModelFormSet a variable from inside the get_context_data? -
Django: Add objects.all.count() to aggregate?
I've been searching how to add X.objects.all().count() result to an existing aggregate logic. I seen that Count() will only work with a foreign key relationship, so how can I add an 'additional field' with the .count() results to the aggregate with only writing it in one block. This is my custom action (Does not work): from django.db.models.functions import Coalesce from django.db.models import Min, Avg, Max, Value as Val, IntegerField @action(detail=False, methods=['get']) def get_stats(self, request, pk=None): total_ads = Ad.objects.all().count() stats = Ad.objects.aggregate( price_min = Coalesce(Min('price'), Val(0)), price_avg = Coalesce(Avg('price'), Val(0.0)), price_max = Coalesce(Max('price'), Val(0)), ads_total = Val(total_ads, output_field=IntegerField()), ) return Response(stats) Error: TypeError: ads_total is not an aggregate expression -
Refer to child class foreign key in base abstract model
I am trying to access the child model foreign key in base abstract model so I don't have to repeat the foreign key in each of the child model.

Django static images receive 404 error in windows production
I am trying to deploy a Django app on a Windows server. I am able to make the pages load and am using wgsi. I am also able to load pages with images when using runserver, just not when accessing via the webserver. I have DEBUG = False. My settings.py looks like this: STATIC_URL = '/static/' STATICFILES_DIRS = [ BASE_DIR / "static", ] STATIC_ROOT = "/assets/" When I do collectstatic, my files are copied into the assets folder.

Django Link a submodel to the main model and display the sub-model widgets on my view with ModelForm
I need to link a "sub-model" with a "main model" to then display a form on my view For the moment I manage to display the form but not the fields of the form of the "sub-model" Here is what I have on my web page: You can see that the info field does not offer me to enter information but only selected among the one that exists outside I would like it to be like the others, that the user is free to indicate what he wants Here is the "main model" class Dispositif(models.Model): info = models.ForeignKey(Infos, on_delete=models.CASCADE) name = models.CharField(max_length=32, default="Nom du dispositif") place = models.CharField(max_length=128, default="Adresse du dispositif") Here is the "sub-model" class Infos(models.Model): comment = models.CharField(max_length=128) chef = models.CharField(max_length=32) and here the ModelForm: class DispositifForm(ModelForm): class Meta: model = Dispositif fields = ['name', 'place', 'info'] widgets = { 'info.comment': django.forms.TextInput(attrs={'placeholder': 'Comment'}), 'name': django.forms.TextInput(attrs={'placeholder': 'Nom du dispositif'}), 'place': django.forms.TextInput(attrs={'placeholder': 'Adresse du dispositif'}) } I tried to create a widget like this but it shouldn't be this way: 'info.comment': django.forms.TextInput(attrs={'placeholder': 'Comment'}), I could very well group everything in the same model but then I will add fields and I prefer to leave with a good organization from the … -
Strange ViewSet Behavior - Django Rest Framework
I set up a ModelViewSet and ModelSerializer for my model Dataset but noticed some strange behavior. When I create new dataset instances the rest-endpoint does not reflect the new additions. However, if I print out the count of dataset instances I can clearly see the new datasets reflected. Has anyone seen something like this before? class DatasetViewSet(viewsets.ModelViewSet): queryset = Dataset.objects.all().order_by('-created_at') serializer_class = DatasetSerializer def get_queryset(self): # correctly prints the number of instances print('new call: ', Dataset.objects.count()) # only prints the correct number when *one* new instance is added, # afterwards new instances are not recognized print('queryset: ', self.queryset.count()) return self.queryset The first print statement in the get_queryset method above will print out the correct number of instances (i.e. 5, 6, 7, 8, ... as I keep adding more instances). The second print statement only captures the first new instance and then remains constant (i.e. 5, 6, 6, 6, ... even as I keep adding more instances). Furthermore, in the example above, a GET request will only yield 6 instances even as I keep adding more. What is going on here and how I can begin to debug this situation? -
Unique Class or extend Class in Python Django

Can't get form to work for comment replies
I can't seem to get the post form to work for post replies (comments for a post). It works via the Django admin but I can't seem to display the form on the template which I think is due to my noobish backend. Layout of the "site": Front: Frontpage contains all posts which shows 3 latest comments for said posts (this part works). Posts: When you want to read a post it redirects you to another page which shows selected post (as normal) and here you can see all comments for the post (currently added directly via Django Admin). Here I want a form so the visitor can reply to the post. (This part does not work). Forms: from django import forms from django.forms import widgets, TextInput, ModelForm from .models import Comments, Post class PostForm(ModelForm): class Meta: model = Post fields = ['entry', 'post_image'] labels = { 'entry': "Post something spoopy:", } widgets = { 'entry': widgets.Textarea(attrs={'rows':10, 'cols':5}) } def __init__(self, *args, **kwargs): super(PostForm, self). __init__(*args, **kwargs) for name, field in self.fields.items(): field.widget.attrs.update({'class': 'input'}) class CommentForm(ModelForm): class Meta: model = Comments fields = ['comment_entry', 'comment_image'] labels = { 'comment_entry': "Answer!", } def __init__(self, *args, **kwargs): super(CommentForm, self).__init__(*args, **kwargs) for name, … -

Django TestCase with Postgresql brokes PrimaryKeys
I have setted up postgresql at my django application, and after that my TestCases had broken. It always throwed ObjectDoesNotExists at any test method after first one. I have narrowed down the issue, and each time test method is called, all objects created at setUp, get their primary keys + 1. Maybe you don't understand but see my code: class ProfileTestCase(TestCase): def setUp(self): user1 = User.objects.create(username="Unit1", email="testuser1@gmail.com", password="123456") user1_profile = Profile.objects.create(user=user1, first_name='User1', last_name='User1') def test_smth0(self): print(Profile.objects.all()) print(Profile.objects.filter(first_name='User1')[0].id) def test_smth1(self): print(Profile.objects.all()) print(Profile.objects.filter(first_name='User1')[0].id) def test_smth2(self): print(Profile.objects.all()) print(Profile.objects.filter(first_name='User1')[0].id) And here is console output for this tests Why this is happening and how to fix this. Here is my connections settings to postgresql database in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'myapp_db', 'USER': 'admin', 'PASSWORD': 'MYPASSWORD', 'HOST': '127.0.0.1', 'PORT': '' } -
What happens when an object is created in Django admin?
I am new to Django. When we learn Python it was taught that when an object is created, the init function is initialized and all the variables that are passed are saved using self keyword. For eg: class Movie: def __init__(self,name,caption,budget): self.name = name self.caption = caption self.budget = budget obj1 = Movie('Taken',"Fight movie",250) obj2 = Movie('Wanted','Comedy movie',300) print(obj1.name) print(obj2.name) Here, in the above example when I clicked the run, two objects are initialized and saved. Hence when I print both the movies names are printed. Now when I read the documentation in Django, it says that when we create an object of a model in Django admin, it calls the save function to save the instance. Until now I was in the assumption that, the dunder init will be called just like in plain Python. The Django model looks like this: class Employee(models.Model): name=models.Charfield() dept=models.Charfield() def__str__(self): return self.name Also, here I don't see any init function explicitly defined. But when I ctrl + click on the Model, I can see a number of functions defined and there is init as well as save function defined. Now I want to know which function is called when we save any object … -
Django - Searchbar in Listview | How to define and process it
i'm totally new to django and python. I would like to add a search bar working on my Listview page as I've seen on the Django admin-site. I've seen a lot of django docs, many explainations and plenty of tutorials on the web but i have to say that I'm confused and could not find a solution for my problem. What i want to do: I have a page with a (class-based)ListView that presents 5 fields from my table. I would like to add a search bar working on 2 of these 5 fields (object id and description) as i've seen on the Django admin-site. Looking at the Docs and web these are a lot of different propositions to do that(queryset, filter, context, Q...). Personally I would like to work with the context. I tried to recover info from my searchbar but what I have implemented and tried since now is not working. Could someone help me on this matter? What is the best practice and approach? Indications on how to manage this with some code exemple? Thanks in advance! #HTML <form method="GET"> <input type="text" name="q" value="" id="searchbar" autofocus> <input class="button" type="submit" value="Search"> </form> #View class AircraftListView(ListView): model = Aircraft … -

How to use clear checkbox for ajax fileupload with modelform django
i am quite a noob on django and ajax so please excuse me if there is some big mistake or ugly code in my work. So I am working on an app where the user must upload different documents in a modelForm (linked to another model in 1:1). The user will probably not upload all the documents at once. I am using ajax to have a progress bar for the user. So far, the upload works fine, replacing document with another works too, but i have a problem when it comes to using the clear checkbox that django provides when a document has already been uploaded.
