Is it possible in Django admin to make a model out of an intermediate table and create a one to one relationship with another model?
I have 2 tables that have a many to many relationship. I want to know if it is possible for me to make a model out of it and then create a one to one relationship out of it with another model. What I want to do is to have this model from the intermediate table display its fields in a list display together with the fields of the other model where it has a one to one relationship. -
Django-Filter returns return the request object
I was trying to dynamically filter the queryset in Django using Django-filters library in DRF but the filters send the response exactly as the same to request ie if i choose mode = transfer the response is { "data": { "mode": "transfer" } } the filterset_class is defined in the views and queryset is passed on to it along with the request type. views.py from .filters import DataFilter def get(self, request): query_set = ModelName.objects.all() queryset_filter = DataFilter( request.GET, queryset=query_set) return Response({"data": queryset_filter.data}, status=status.HTTP_200_OK) filters.py from django_filters import rest_framework as filters from .models import ModelName from common.models import MODE_CHOICES class DataFilter(filters.FilterSet): currency = filters.ModelMultipleChoiceFilter(lookup_expr='iexact') coin_type = filters.ModelMultipleChoiceFilter(lookup_expr='iexact') mode = filters.ModelChoiceFilter( lookup_expr='iexact', choices=MODE_CHOICES) max_amount = filters.NumberFilter( field_name='price', lookup_expr='gt') min_amount = filters.NumberFilter( field_name='amount', lookup_expr='lt') class Meta: model = ModelName fields = ('currency', 'coin_type', 'mode', 'max_amount', 'min_amount') The django-filters documentation suggests django-filter backend can be used by default by adding it to the DEFAULT_FILTER_BACKENDS. Is there some configuration that i am missing or something -

Django 2.1.3 reset password link not displaying
After upgrading to Django 2.1.3, I noticed the "Forgotten your password or username?" link was missing from the admin login page. After some investigating, I found the that the django.contrib.auth.urls.py module used the name password_reset for the reset url, while in the django/contrib/admin/templates/admin/login.html template the url was named admin_password_reset: django.contrib.auth.urls.py (line 16) path('password_reset/', views.PasswordResetView.as_view(), name='password_reset'), django/contrib/admin/templates/admin/login.html (starting at line 54) {% url 'admin_password_reset' as password_reset_url %} {% if password_reset_url %} <div class="password-reset-link"> <a href="{{ password_reset_url }}">{% trans 'Forgotten your password or username?' %}</a> </div> {% endif %} When I changed admin_password_reset to password_reset in Django's login.html, the link showed up on the login page and worked as expected. In my urls.py I have: path('lodging/', include('django.contrib.auth.urls')), My project has no other modifications to the authentication system. Is this a bug or am I missing something? -
"python social auth" adding a backend
I'm trying to add a new social backend based on the python social auth library but when I click my "Login with X" or "Sign up with X" button it always redirects me back to the login page without logging in.

Django: admin.site.site_header set, but not visible for own pages
I set admin.site.site_header = 'Fooo' like explained in the docs: https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.AdminSite.site_header This works very nice for all normal admin-pages. I have an additional (custom) page which I want to look like the admin page. I use {% extends 'admin/base_site.html' %} in my template. On this page site_header 'Fooo' is not displayed. The normal/default django string is visible. What am I doing wrong? -

Django template default filter with nullable boolean values
I need to pass a boolean variable to a template. To convert it to js boolean you usually do: {{ boolval|yesno:'true,false' }} Now my boolvar may not exist. In that case I need it to default to true, so I am trying this: {{ boolval|default_if_none:'true'|yesno:'true,false' }} Unexpectedly, the result of this is false. I am trying to debug what {{ boolval|default_if_none:'true' }} produces but I am getting syntax errors. Not sure what's going on, but it is definitely not producing true. How can I achieve with filters the behavior I'm after? -

Which approach is better in Django Jsonfield or ForeignKey?
Such a question, I want to create a price comparison site, there are two ideas how to implement a list of prices from different stores. First via ForeignKey class Price(models.Model): price = models.DecimalField() shop = models.CharField() class Product(models.Model): name = models.CharField(max_length=255) prices = models.ForeignKey() JSONfield second method class Product(models.Model): name = models.CharField(max_length=255) data = JSONField() """ Product.objects.create(name='product', data={'price': 999, 'shop': 'Amazon.com'} def __str__(self): return self.name If anyone has experience, what works faster and more reliable if a large number of goods? Thanks for the early ones. -
Trigger a modal on django form submit
I have a series of Django forms and formsets that are connected together in a series of steps. When the final form step is submitted a celery task is started to create an entity based on all the information provided. The way this is currently working, is that the final form is submitted (and the task starts) and then redirects to a page which lets the user know that the entity is being created and then redirects once this is complete. However, I now want to have this loading page show up as a modal on the previous page, rather than show on an entirely new page. I have previously been doing this almost solely in Django. When I submit the final form the form_valid looks like this (I am using django-extra-views to make formsets so it is slighlty different from normal): def forms_valid(self, form, inlines): self.object = form.save() models.ActivityBaseNext.objects.create( activity_base=self.activity_base, order=self.activity_base.get_next_next_step_order(), activity_configure=self.object, ) for formset in inlines: formset.save() transaction.on_commit( tasks.activity_configure.s( id=self.object.pk, ).delay ) return HttpResponseRedirect(self.object.get_current_next_url()) which causes the redirect to the loading page, which looks like so: class ActivityConfigureStatus(LoginRequiredMixin, DetailView): model = models.Activity template_name = 'alert.html' title = 'Create Activity' display_text = 'Importing activity data' refresh_secs = 1 def … -

Django: When I delete item from one of the user's shopping cart, that same item gets deleted from every user's shopping cart
Using python 3.7 When I add item to the cart, the item gets added individually to each user, but I have delete button on the cart details page and the function in views.py looks like this: def delete_cart_item(request, item_id): user_profile = get_object_or_404(User_Profile, user=request.user) shopping_cart = user_profile.shopping_cart_set.first() item = shopping_cart.items.get(pk=item_id) item.delete() return redirect('Sales:cart_details') Those are my models: class User_Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) class Item(models.Model): item_name = models.CharField(max_length=200) item_price = models.IntegerField() item_description = models.CharField(max_length=300) item_bought_price = models.IntegerField() stock_level = models.IntegerField() restock_level = models.IntegerField() class Cart_Item(models.Model): item = models.OneToOneField(Item, on_delete=models.SET_NULL, null=True) class Shopping_Cart(models.Model): ref_code = models.CharField(max_length=15) owner = models.ForeignKey(User_Profile, on_delete=models.SET_NULL, null=True) items = models.ManyToManyField(Cart_Item) What is the issue here? I tried changing on_delete=models.SET_NULL of Cart_Item to on_delete=models.CASCADE but that didn't seem to change anything. There also is a weird issue that when the cart is empty and I add the first item, that item cannot be deleted from the page, I can delete it from shell though. -
Django : Issue with MultiValueDictKeyError with download function
I would like to get your help in order to improve my code and get the possibility to download document thanks to 2 different ways. Explanations: The first method let to check some documents and user has to fill an email field. Once it done, a modal appears with pre-filled fields according to previous email address because a queryset is executed with a filter on email adress This is the main process to download documents. The second method is different. I generate an unique hyperlink with the document id in the url. But through this way, I don't need the email address as previously. My codes: This is my model.py file : class Document(models.Model): code = models.CharField(max_length=25, verbose_name=_('code'), unique=True, null=False, blank=False) language = models.CharField(max_length=2, verbose_name=_('language'), choices=LANGUAGE_CHOICES, null=False, blank=False) format = models.CharField(max_length=10, verbose_name=_('format'), choices=FORMAT_CHOICES, null=False, blank=False) title = models.CharField(max_length=512, verbose_name=_('title'), null=False, blank=False) publication = models.ForeignKey(Publication, verbose_name=_('publication title'), related_name='documents') upload = models.FileField(upload_to='media/files/', validators=[validate_file_extension], verbose_name=_('document file'), null=False, blank=False) class Meta: verbose_name = _('document') verbose_name_plural = _('documents') class Customer(EdqmTable): email = models.EmailField(max_length=150, verbose_name=_('e-mail'), null=False) first_name = models.CharField(max_length=70, verbose_name=_('first name'), null=False) last_name = models.CharField(max_length=70, verbose_name=_('last name'), null=False) country = models.ForeignKey(Country, verbose_name=_('country')) institution = models.CharField(max_length=255, verbose_name=_('institution'), null=True) class Meta: verbose_name = _('customer') verbose_name_plural = _('customers') def … -
Deploying Seprate React Frontend and Django DRF API
I have a react frontend made with create-react-app to deploy a production build of this I just do npm run build. My app uses a Django Rest FrameWork API backend. How can I setup the app for deployment on a single server. Is there a way I can store the React Frontend and route to it in Django and have requests from the Frontend hit a api/ view or endpoint.

Django rendering multiple images using inlineformset
A django newbie here, I am trying to enable uploading multiple images in one classified post. I am using a generic class-based view, CreateView, but the formset for images are not rendered in my html, only the ClassifiedForm and the submit/publish button. Note this is a duplicate for this question but it was not answered. My files are like this (Just the important parts, I have skipped some code chunks). models.py class Classified(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODE, on_delete=models.SET_NULL) timestamp = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=255, null=False) content = models.CharField(max_length=1000) class ClassifiedImages(models.Model): classified = models.ForeignKey(Classified, default=None,\ on_delete=models.CASCADE, related_name='classified_images') images = models.ImageField(upload_to=get_image_filename, verbose_name='Image') forms.py class ClassifiedForm(forms.ModelForm): class Meta: model = Classified fields = ["title", "content"] ImagesFormSet = inlineformset_factory(Classified, ClassifiedImages, fields =["images"], extra=5) I just think this views.py is wrong but it goes like this class CreateClassifiedView(CreateView): model = Classified message = _("Your classified has been created.") form_class = ClassifiedForm template_name = 'classifieds/classified_create.html' def get(self, request, *args, **kwargs): self.object = None form_class = self.get_form_class() form = self.get_form(form_class) images_form = ImagesFormSet() return self.render_to_response( self.get_context_data(form=form, images_form=images_form )) def post(self, request, *args, **kwargs): self.object = None form_class = self.get_form_class() form = self.get_form(form_class) images_form = ImagesFormSet(self.request.POST) if (form.is_valid() and images_form.is_valid()): return self.form_valid(form, images_form) else: return self.form_invalid(form, images_form) def … -
