How to reorder the fields when we have two forms of two models in Django?
How can I reorder the fields in the form of my Django models ? I have two models : Student inherited from the User class inherited from an AbstractBaseUser class. I want the student to register on my webpage having these fields in this order : firstname ; lastname ; address ; email ; password. But Firstname and Lastname are in the User class, address in the Student class, then email and password in the User class. How can I reorder them ? Here is my code : forms.py : class CreateUserForm(UserCreationForm): class Meta: model = CustomUser fields = ('firstname', 'lastname', 'email') class StudentForm(forms.Form): address = forms.CharField(max_length = 30) class Meta: model = Student fields = ['address'] models.py : class CustomUser(AbstractBaseUser, PermissionsMixin): email = models.EmailField('email address', unique=True) firstname = models.CharField(max_length = 30, null = True) lastname = models.CharField(max_length = 30, null = True) class Student(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, null=True, on_delete=models.CASCADE) address = models.CharField(max_length = 60, null = True) register.html : <div> <form method="POST" action="{% url 'register' %}"> {% csrf_token %} {{ form.as_p}} {{student_form.as_p}} <button class="btn btn-secondary"> Je m'inscris </button> </form> </div> -
How to make custom filter based on user
I have an application which is being used globally at my company. It is used to track internal hardware inventory. Each product is associated with a category (for example a product could have a category of 'cable', or 'development kit', or 'PC peripheral'). Now, each category is associated with a location (for example 'Boston', 'Budapest', and so forth). I have extended the user model in django to allow for a location to be associated with each admin user. I want to create a dropdown list filter in the admin space for each user. The user should be able to filter by product categories, but only the categories with the same location as the user. models.py ##product model class dboinv_product(models.Model): pk_product_id = models.UUIDField( default = uuid.uuid4, primary_key=True, null=False ) product_creation_time = models.DateTimeField( auto_now_add=True, null=True ) product_name = models.CharField( max_length=50, null=False ) product_description = models.CharField( max_length=500, null=True ) current_qty = models.IntegerField( null=False ) fk_location_name = models.ForeignKey( dboinv_location, verbose_name="Location name", default='Boston', on_delete=models.CASCADE, null=True, blank=True ) fk_product_category = models.ForeignKey( dboinv_product_category, verbose_name='Product category', on_delete=models.CASCADE, null=True, blank=True ) def __str__(self): return f"{self.product_name}, {self.fk_location_name}" class Meta: db_table = "dboinv_product" verbose_name = "Product" managed = True ##category model class dboinv_product_category(models.Model): pk_category_id = models.UUIDField( default = uuid.uuid4, primary_key=True, null=False … -
Session variable (Django) in one route exists, and in other is None

How can i pass a Django form to Html Asynchronously with intial data
I am representing data in a table and taking input for new data using a form on the same webpage. In my table at the end column, there is an update button for each row. When I will click the button, I want the existing form will populate with the data of the row. I want to update the data of a selected row asynchronously. I did it quite well with regular Django. But when I tried to do it with ajax/jquery. I have encountered a problem passing the form with populated data to HTML/script(Django view to frontend). I have added few lines of code below. Here is my Django view, def update_view(request,pk): p = People.objects.get(pk=pk) if request.method == 'POST': form = RecordUpdateForm(request.POST,instance=p) if form.is_valid(): form.save() else: form = RecordUpdateForm(instance=p) return !!! here is the url path, path('<int:pk>/update_view',views.update_view,name="update-view"), -
Cannot Debug Django using pdb

Filtering parent/child using NestedTabularInline in Django
Stuck in getting conceptually my head around a Django/ORM problem for a few days. Searching online (stackoverflow) didn’t address my problem. Furthermore I’m quite new to Django and Python and trying to understand the concepts of abstract models, multitable inheritance and proxy models but I don’t think that’s the solution. Outline: I’ve a general description of a activity/method/task model which describes a general assembly instruction. See my Activity/Method/Task/TaskImage model. On a actual product I want to execute a plan, in which I concretize a series of activity steps, hence my PlanActivity and PlanMethod models. Moreover for each actual plan I want to assign a bill of materials to make the product (therefore the TaskBOM). For convenience I’m heavily using NestedTabularInline for both drag/drop and inline properties. My problem is a bit twofold: Any activity step can have only one single method (Q1) and the available method’s need to be filtered (Q2) on it’s parent (activity). The tasks need to be filtered on the same way based on it’s parent (method). I think/hope my model is sane (thus no need for abstract models, multitable inheritance and proxy models) and I believe I need to use get_queryset or formfield_for_foreignkey functions in some … -

Django Rest Registration (3rd party package) asking for signature to verify registration.. What signature?
I'm using 'django rest registration' and when I create a new user everything works fine. The issue is that the 'verify-registration' endpoint requires a user_id, timestamp and a signature and I have no idea what timestamp and signature I'm supposed to post to the endpoint. The documentation is not really giving me any clues. Can anyone tell me what exact signature this 'verify-registration' endpoint is asking to have posted to it please? Here's the piece from the docs: and then it should perform AJAX request to https://backend-host/api/v1/accounts/verify-registration/ via HTTP POST with following JSON payload: { "user_id": "<user id>", "timestamp": "<timestamp>", "signature": "<signature>" } -

DRF exception 'NotAuthenticated' raising 500 Internal Server Error in place of 401/403
I have a Django middleware where I verify a firebase IDToken. from rest_framework import exceptions def process_request(request): ... try: decoded_token = auth.verify_id_token(id_token) uid = decoded_token['uid'] except: raise exceptions.NotAuthenticated(detail='not authenticated') When the verification fails, auth raises an exception, which is caught by the try except block.

DRY-rest-permissions somehow does not check my object permissions except global permissions
I have recently started implementing dry-rest-permissions, but I can't seem to get it to check the has_object_permissions, it appears that only the global permissions work for me.
