Boostrap Modal and loading images in Django
Firstly I am a beginner at Django but am slowly learning, I have deployed a couple of Django projects, but I have come up against a problem where I have run out of ideas on how to solve due to a lack of knowledge. I have no experience really with the frontend, I have yet to touch Boostrap (although obviously know some HTML ) or JS in detail. I am using a HTML template to build a Photography portfolio, I have a Album view with image thumbnails which work nicely and I have a href to the list of images within that Album. The problem is that template uses Boostrap Modal to open the list of images within the same page, this looks very nice and I want to try and keep it working but unsure how to pass my Django data (ie., the slug from the href ) through the modal. What I have attempted is to split my gallery-detail template which takes in the listview of the Album images filter by that album, and then include that within my main Gallery template which uses my Gallery ListView to show the thumbnails. I though the modal would work this … -
How display categories in forms only for user who created this?
I am creating app for control transaction (expense, income, budget). I want each user to be able to create their own spending categories and their own expenses. All expenses and categories created by a user are to be visible only to that user. If user A creates the category "Food123" then user B cannot see it. He can create his own such category. I've created two models - Category and Expense. class Category(models.Model): name = models.CharField(max_length=100) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="category") class Expense(models.Model): name = models.CharField(max_length=100) amount = models.DecimalField(max_digits=8, decimal_places=2) category = models.ForeignKey(Category, on_delete=models.CASCADE) date = models.DateTimeField(auto_now_add=True) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="expense") I use a generic view when creating expenses and categories. class ExpenseListView(LoginRequiredMixin, ListView): model = Expense context_object_name = 'expense' template_name = 'expense/expense_list.html' def get_queryset(self): return self.request.user.expense.all() class ExpenseCreateView(CreateView): model = Expense success_url = '/record/expense' form_class = ExpenseForm def form_valid(self, form): self.object = form.save(commit=False) self.object.user = self.request.user self.object.save() return HttpResponseRedirect(self.get_success_url()) class CategoryCreateView(CreateView): model = Category success_url = '/record/expense' form_class = CategoryForm def form_valid(self, form): self.object = form.save(commit=False) self.object.user = self.request.user self.object.save() return HttpResponseRedirect(self.get_success_url()) What is more, I've used forms.py. class ExpenseForm(forms.ModelForm): class Meta: model = Expense fields = ('name', 'amount', 'category') class CategoryForm(forms.ModelForm): class Meta: model = Category fields … -
django-polymorphic: Admin website error: displaying inline admin with ManyToMany using intermediate polymorphic model
I'm a django novice. It's my first Django project. As you can guess it from the title of the question, my problem is a bit long to explain. In short: I want to know how to make a basic Admin Inline display for a ManyToMany relationship with intermediate polymorphic model. I'm having an TemplateDoesNotExist at /admin/blu_forms/contactentry/e6529155-82a3-43b6-9e14-34951c88471a/change/ error. The initial idea is simple: I have two classes ContactEntry and ContactField. A contact entry can have many fields and vice-versa, so we have a ManyToMany relationship between the two. Since I want to store typed data in this relationship (because a given field is linked to typed data for a given entry - field relation) so I use an intermediate model (through model) to hold that data. The correct typing is handled with Polymorphism (django-polymorphic). This works well. I made a custom script to populate the database (PostgreSQL) and it works nicely. My issue is with the admin website. When I register ContactEntry and ContactField, I see the list of data, but when I click to see the details of a specific instance, I get an error. The correct lists of instances: And the error I get when I click for instance … -
React native face authenticaion and authorization
I have a project which I have to implement a face recognition service. Scenario is: Existing user authenticates with his face then by validating his face app or server finds out which user is trying to log in, then sends the access_token back to the userwithout entering username/password or guest user tries to register and while entering credentials app reads his/her face and sends the face credential to the backend as well. I tried to use expo-local-authentication but it doesn't give me something unique about the face it read so I can send it to backend. Is there any service or library out there? Btw backend is on django -

Disconnect all recivers of particular sender and signal than reconnect them in django
Is there any way I disconnect all receiver of a model in specific signal (like post_save) than reconnect them? # some thing like this all_receiver = collect_receivers(signal=post_save, sender=MyModelClass) post_save.disconnect(all_receiver, sender=MyModelClass) # do some work post_save.connect(all_receiver, sender=MyModelClass) seems post_save.disconnect(sender=MyModelClass) just work fine with disconnecting signals but Django documentation is not clear about what will happened if I pass just sender. and I baffled about how can I reconnect, disconnected receiver? Note that because my app is 3rd-party I don't have access to receivers but, for one of my features I have to mute all receiver connected to my model in post_save than reconnect them. -

How to restore deleted table from django migrations?
I've deleted both table and 0001_initial.py migration file from a model. I didn`t think I will need this model anymore, but now I do need it. The problem is that python manage.py makemigrations doesn't create a table with the name of deleted table and therefore my migrations are only displayed in migrations files. But they don`t affect database. How can I create or restore that table again or should I delete the whole database and restore everything afterwards? Thanks in advance! -

Resolving a ForeignKey field pointing to the model it belongs to

Duplicate instances not removed from queryset
I'm coming across a problem with the queryset returned in the get_tag_posts method within the Profile model. With the query as it is written, it won't remove duplicates even though .distinct() is being invoked. To provide a brief illustration of the problem: Question 1 - Tag A Question 2 - Tag A Question 3 - Tag A, Tag B As get_tag_posts is invoked it includes the following queryset: <QuerySet [<Tag: A>, <Tag: A>, <Tag: A>, <Tag: B>]> Yet I'm expecting the queryset to be returned as: <QuerySet [<Tag: A>, <Tag: B>]> From there each instance is annotated to calculate the number of times a given tag has been posted by a user. Why are duplicates of a single instance not being removed in this case? class Profile(Model): user = OneToOneField(settings.AUTH_USER_MODEL, on_delete=CASCADE) def get_tag_posts(self, order_by=None): if not order_by: order_by = "-question__date" elif order_by == "name": pass else: order_by = "-score" questions_with_tag = Subquery(self.questions.filter( tags__name=OuterRef("name")).only('id')) tags = Tag.objects.filter( question__profile=self ).distinct().order_by(order_by) return { 'records': tags.annotate(times_posted=Count(questions_with_tag)), 'title': f"{tags.count()} Tags" } class Tag(Model): name = CharField(unique=True, max_length=25) class Post(Model): body = TextField() date = DateTimeField(default=timezone.now) comment = ForeignKey('Comment', on_delete=CASCADE, null=True) profile = ForeignKey( 'authors.Profile', on_delete=SET_NULL, null=True, related_name='%(class)ss', related_query_name="%(class)s" ) vote = GenericRelation( 'Vote', related_query_name="%(class)s" ) … -
