DRF Serializer doesn't raise error in update but doesn't update
I have a model with a foreign key I'm trying to update via the serializer, I don't want to use the built-in ID field to find the foreign key. My Serializer code seems to be working fine, no error is being raised but it doesn't update the foreign key field.

Adding more than one model using Django ModelFormMixin in views.py
I have a Django related problem. I have two models; Model A & Model B. Model B is related to Model A trough a foreign key. In my views.py I have a CBV for a Single instance of Model A using generic.DetailView & generic.ModelFormMixin. I'm now wondering if there is a way to pass in more than one instance of a model in this view. At this point, I'm only able to pass in the Model A (which enables me to change values of the model in the DetailView). The idea would be something like this (this is ofc not working): #views.py class SingleModelA(generic.DetailView, ModelFormMixin): model = ModelA, ModelB I assume this would probably also require some changes in the post() method as well, which at the moment looks like this: def post(self, request, *args, **kwargs): self.object = self.get_object() form = self.get_form() if form.is_valid(): return self.form_valid(form) else: raise ValueError(f"INVALID FORM: {form}") I am able trough get_context_data() to present the ModelB instances belonging to this instance of ModelA, but I would like to access the ModelB instance's form in order to update ModelB straight from ModelA's DetailView. Any help is much appreciated! -
How to dynamically change a form in django based on user input (before submission)
I'm doing a web page that contains a form that must be changed dynamically based on the previous user inputs (before it's submitted). For example, if a name ends up with the string S.L, it needs to automatically span the rest of the fields to introduce the company data, if not it must submit the form with the default values or with any value at all. The form inherits from a model and everything is rendered as a crispy form. In the views.py I have: @login_required def form_home(request): if request.method == 'POST': Inputs = InputsForm(request.POST) if Inputs.is_valid(): inp = Inputs.save(commit=False) inp.author = request.user inp.email = request.user.email data = {'email': request.user.email, **Inputs.cleaned_data} obtain_calculate_create_send(data) inp.save() messages.success(request, f'Your form is valid!') return redirect('result/' + str(inp.pk) + '/') else: messages.warning(request, f'Please, check the inputs and enter valid ones') content = {'Inputs': Inputs, 'title': 'valuations'} else: Inputs = InputsForm(request.POST or None) content = {'Inputs': Inputs, 'title': 'valuations'} return render(request, 'valuations/form_home.html', content) In forms.py: class InputsForm(forms.ModelForm): # Basic Info country_choices = import_lists('Countries', equal=True) years = import_lists('years') name = forms.CharField(label='Company Name', initial='Example.

Django Filter: "Sort By" Feature

React frontend + graphene Django backend SPA deployment
I want to deploy a SPA on only one VM, with debian 10. What I wanted to do is all routes to go to index.html of my static react app, except /admin/* and /graphql/* which should lead to the corresponding django pages. I have tried using Caddy, setting up a reverse proxy for /admin/* and /graphql/* but I end up with a working frontend and a working admin page (but the style of this page is not loaded for some reason). However, the graphql page does not work at all (blank page) and the frontend cannot make request to the backend. Do you know how I should do it? I was wondering if I'd rather go with nginx and uWSGI instead of using Caddy, with which I had to use gunicorn, but then I would need help to configure nginx properly. Or maybe the way I wanted to do it is a dead-end and I should totally change it? Thanks for your help! -
Django new version 3.1, the settings file have some changes

Body not Posting in Django Rest API call using Javascript fetch
