Can I use the default login view to login multiple users to different profile pages in Django?
I am using Django 3.2 and I recently learned to create custom user models with email instead of username and the default authentication views. I implemented the following form in my login.html <form action="{%url 'login'%}" class="mx-3" method="post"> {% csrf_token %} <div class="emailAddressLog"> <label data-error="wrong" data-success="right" for="modalLRInput10" class="mt-3">Email Address:</label> <div class="input-group mb-3"> <i class="bi bi-envelope-fill input-group-text"></i> <input type="text" class="form-control validate" name="username" autocapitalize="none" autocomplete="username" autofocus="" id="id_username" maxlength="60" required=""> </div> </div> <div class="passwordLog mb-4"> <label data-error="wrong" data-success="right" for="modalLRInput11">Password:</label> <div class="input-group"> <i class="bi bi-lock-fill input-group-text"></i> <input required type="password" id="id_password" class="form-control validate" contenteditable="true" autocomplete="current-password" name="password"> </div> </div> {% if form.errors %} <p class=" label label-danger" style = "color:red"> Your username and password didn't match.

Getting an empty list when using filter - Django REST
I have my API in Django REST Framework: Here is my models.py: class myModel(models.Model): user_email = models.CharField(max_length= 200, null= False) Here is my views.py: class GetItemsByEmail(generics.ListAPIView): def get_queryset(self): email_items = self.request.query_params.get("user_email") if(email_items is not None): itemsReturned = myModel.objects.all().filter(user_email = email_items) return Response(data= itemsReturned) Here is my urls.py: url_patterns = [ path('users/account=<str:id>/shipments', GetItemsByEmail.as_view()), ] My Question: I am getting an empty list, getting nothing from making an API call to the above endpoint.

Django query by filter different attributes from slug
I have a model with lots of attributes. I want to query the model by filters in attritbutes. The problems is that I have to write lots of function to query by different attributes. models.py class ETF(models.Model): ticker = models.CharField(max_length=6, blank=False, db_index=True, unique=True) full_name = models.CharField(max_length=200, blank=False) region = models.ManyToManyField(Region) sector = models.ManyToManyField(Sector) industry = models.ManyToManyField(Industry) # Even more attributes here class Theme(models.Model): name = models.CharField(max_length=50, blank=False, unique=True) slug = models.SlugField(default="", null=False) def __str__(self): return self.name I am writing a function to filter ETF by attritbutes.

Django DRF nested relationships - how to add objects in a ManyToMany field
I am building an API with DRF. I have two models, Folder and User, connected through a ManyToMany field. models.py class Folder(models.Model): title = models.CharField(max_length=20) description = models.CharField(max_length=250) organization = models.ForeignKey(Organization, on_delete=models.CASCADE) users = models.ManyToManyField(User, related_name='folders') def __str__(self): return self.title class User(AbstractBaseUser, PermissionsMixin): username = None email = models.EmailField(_('email address'), unique=True) first_name = models.CharField(max_length=20) last_name = models.CharField(max_length=20) organization = models.ForeignKey( Organization, on_delete=models.CASCADE, null=True, blank=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = UserManager() def __str__(self): return self.email serializers.py class FolderSerializer(serializers.ModelSerializer): class Meta: model = Folder fields = ("id", "title", "description", "users", "organization") def create(self, validated_data): users = validated_data.pop('users') if 'users' in validated_data else [] folder = Folder.objects.create(**validated_data) for user in users: if user in User.objects.all(): User.objects.filter... **not sure** else User.objects.create(folder=folder, **user) return folder The part I am stuck on is the custom create method: basically, users do not get created when the folder is created, they just get added to the newly created folder, so I think that in the for loop for user in users I should check if user exists within the instances of model User and if it does, I should update its property folder. I have no idea how to do so though. Also, I am … -

Django aggregate sum for each user
I'm creating a budget application and wanted to find the sum of each user who's signed in. Right now I'm using function-based views and I sum up the expenses with Post.objects.aggregate(sum = Sum('expense')) The issue with this is it sums up everyone in the database but I wanted it to only sum up the expenses of the user that is currently signed in. In my model, I have an author field but I'm not sure how to go about summing only for the user currently signed in. -

Django-Tinymce with Tailwind CSS
I am currently using django-tinymce4-lite for my project and everything else works as expected. But on the actual rendered HTML page where the tinymce4 formatted content is supposed to be displayed, tailwind-preflight messes up the formatting with lists and spaces. I found this solution here. It is the exact problem I am facing. The first answer doesn't work for me and I want to get that working. I am following this tutorial to use Tailwind CSS with Django. I am new to npm so I blindly followed, and everything works but when I try to implement the first answer nothing happens. Using the second answer works but then it messes up the entire front-end. -

Inheritance: class method not accessible through use of Foreign Key
Inheritance: class method not accessible through use of Foreign Key Hello! Problem I have multiples classes that inherit from the same class. There are differents relationships between instances of these classes that I need stored in another class (Relationship). To be able to link these different classes together, I use the "mother" class they all inherit from as a ForeignKey. Everything works, except that I cannot access class methods from the subclasses when I access their instances through the Relationship table (Foreign Key). Is there any way I could access the class method of a subclass when using the "superclass" as a Foreign Key? Code My code is as follows: models.py class SuperClass(models.Model): random_attribute = models.CharField() class A(SuperClass): some_attribute = models.CharField() class B(SuperClass): some_other_attribute = models.CharField() def class_b_method(self): some_code = 'goes_here' return some_code class Relationship(models.Model): parent = models.ForeignKey( 'app.SuperClass', related_name='parent', on_delete=models.CASCADE ) child = models.ForeignKey( 'app.SuperClass', related_name='child', on_delete=models.CASCADE ) views.py def do_stuff(): a = A('a') b = B('b') relationship = Relationship(parent=a, child=b) relationship.child.class_b_method() This throws the following error: AttributeError at xxx 'SuperClass' object has no attribute 'class_b_method' I understand why the error is there and what it means, but I have no clue as to how to access a class … -
Websocket can only send and receive messages within the same network. (Django3 channels3 on Elasticbeanstalk(linux2) and elasticache)
I developed a web program for video call and chat using Django-channels and deployed it to AWS Elasticbeanstalk and Elasticache redis for websocket.

Django admin - UI modification on nested models
I'm working on a project developed in Python 2.7 and Django 1.11. More in details, i'm working on an admin page with nested models. This page contains three models and the last one is itself nested. To do this, the python package django-nested-admin (v. 3.2.4) has been used. Here the involved models: class SampleModelOne(Model): # ... some fields class SampleModelTwo(Model): field_1 = models.ForeignKey(SampleModelOne, ...) # field_2, _3, _4 class SampleModelThree(Model): test_1 = models.ForeignKey(AnotherModel, ...) test_2 = models.BooleanField(default=True) Here the admin.py: import nested_admin from dynamic_raw_id.admin import DynamicRawIDMixin class SampleOneAdmin(nested_admin.NestedModelAdmin): list_display = (..., ...) list_display_links = (..., ...) ordering = (...) inlines = [SampleTwoInline, SampleThreeInline, SampleFourInline] admin_register(SampleModelOne, SampleOneAdmin) class SampleFourInline(DynamicRawIDMixin, nested_admin.NestedTabularInline): model = SampleModelTwo fields = ('field_2', 'field_3', 'field_4') dynamic_raw_id_fields = ('field_2',) inlines = [SampleFiveInline] class SampleFiveInline(nested_admin.NestedTabularInline): model = SampleModelThree form = forms.SampleFormOne The SampleFormOne is used to have a select with autocompletion on test_1 field.
