Django - is_valid returns false for authentication built-in login form
Can anyone figure out why when I fill out the form it returns False for is_valid? forms.py class LoginForm(AuthenticationForm): class Meta: model = User fields = '__all__' views.py class LoginView(FormView): form_class = LoginForm template_name = 'login.html' def post(self, request, *args, **kwargs): form = LoginForm(self.request.POST) if form.is_valid(): return HttpResponse('valid') else: return HttpResponse('not valid') login.html <form action "" method = "POST"> {% csrf_token %} {{form|materializecss}} <button type = "submit">Login</button> </form> As an extra, the following change to views.py returns the username and password so I know it has been passed to the POST request: class LoginView(FormView): form_class = LoginForm template_name = 'login.html' def post(self, request, *args, **kwargs): form = LoginForm(self.request.POST) return HttpResponse (self.request.POST.get('username')+ ' ' +self.request.POST.get('password')) -

Django DB Design and API Guidance
This is my first Django app, and also my first time building an app, and I am seeking some DB and API guidance. I have an app that functions as an online directory and marketplace. What I aim to do is to provide the app to many different organizations such that the organizations have their own online directory's and marketplace's where they can manage it fully on their own, but that their data is still linked to my database so that I can then operate on the data for machine learning purposes. This is a pretty standard/routine practice, I realize, but I am trying to wrap my head around how best to make it work. For each organization, would there just be an instance of the app which would then be a separate app or interface that connects to the original? From my newbie understanding, that is essentially what an API is, correct? -

Django and modifying models to reflect a specific ERD
I have the following Django Model: from django.db import models from django.utils.text import slugify class Project(models.Model): name = models.CharField(max_length=100) slug = models.SlugField(max_length=100, unique=True, blank=True) budget = models.IntegerField() def __str__(self): return self.name def save(self, *args, **kwargs): self.slug = slugify(self.name) super(Project, self).save(*args, **kwargs) @property def budget_left(self): expense_list = Expense.objects.filter(project=self) total_expense_amount = 0 for expense in expense_list: total_expense_amount += expense.amount # temporary solution, because the form currently only allows integer amounts total_expense_amount = int(total_expense_amount) return self.budget - total_expense_amount @property def total_transactions(self): expense_list = Expense.objects.filter(project=self) return len(expense_list) class Category(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE) name = models.CharField(max_length=50) def __str__(self): return self.name class Expense(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE, related_name='expenses') title = models.CharField(max_length=100) amount = models.DecimalField(max_digits=8, decimal_places=2) category = models.ForeignKey(Category, on_delete=models.CASCADE) class Meta: ordering = ('-amount',) I don't like the current setup, it seems to unnecessarily bind and expense category to a project, instead of to a given expense. So, I want to start working towards the following ERD, starting with the category side of things: When I try to modify the models so that category is no longer a Foreign key of Project: class Category(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name but rather expense, I get the following error: category_list = Category.objects.filter(project=project) This comes out … -

css on the relevant position of two components
I am super new to css, so apologize if the question is stupid. I have two components on a page, one is called .sub-list , which is a side bar that contains the names of all the groups available, the other main component is post-list, which has all the posts listing. I am really confused about all the positions option outhere. I've tried aboslute position for the two components and relative positions, but with screen decrease or increase, the display just completely falls apart.

Custom functions in __init__.py cause Django Apps Aren't Installed Yet Error

Django dynamically display a list but ignore some items
I am trying to show a list of groups on the sidebar on my html using Django. The first item will always be "all". so when I tranverse through all the groups/subreddits, I would first display "all" and then display the rest. however, when I display the rest and when it hits "all" again, instead of doing nothing, it seems to be printing a empty line because later when I display it in forms, I notice that I have a blank cell. I wonder how do I make sure that it just ignores "all" and goes on to display the next group without the empty space. Here is the code: <div class="post" id="title"><h4>Groups </h4></div> {% for sub in subreddits %} {% if sub.name == 'all' %} <div class="post"> <a href="{% url 'sub_detail' pk=sub.pk %}">{{ sub.name }}</a></div> {% endif %} {% endfor %} {% for sub in subreddits %} <div class="post"> {% if sub.name != 'all' %} <a href="{% url 'sub_detail' pk=sub.pk %}">{{ sub.name }}</a> {% endif %} </div> {% endfor %} -
Django Rest Framework action when request comes in
I'm creating a Django project that uses Django REST Framework for the API. Other projects will be making POST, PUT, and DELETE requests to this project. When one of those requests comes in, I want to send a message to a websocket group using channels. For some reason I am struggling to do this. I am using ThreadViewSet, which extends ModelViewSet, for a model named Thread. class ThreadViewSet(ModelViewSet): queryset = Thread.objects.all() serializer_class = ThreadSerializer I have tried adding the channels call to this class but it doesn't seem to be run: class ThreadViewSet(ModelViewSet): queryset = Thread.objects.all() serializer_class = ThreadSerializer channel_layer = get_channel_layer() async_to_sync(channel_layer.group_send)("group", {'type': 'new_message', 'message': "New Thread"}) The next thing I tried was overriding create(), update(), and destroy() and this worked, but it seemed like so much work for one simple task. Am I missing something? There has to be an easier way to do this. -
Django how to load statics inside a python file

Using Vue with Django: How to separate publicPath from static file prefix
I'm trying to convert my existing and sprawling Django project, which currently uses Vue from a CDN in individual pages on the frontend, to an SPA via NPM with the backend and frontend now separate (except for Django handling some URL routes and loading the Vue initially). I'm running into a problem with static files and URL routing. In vue.config.js, I was originally advised to set values as follows: const pages = { index: "src/main.js" }; module.exports = { runtimeCompiler: true, publicPath: "/static/vue/", outputDir: "./dist/static/vue/", indexPath: "../../templates/vue_index.html", pages: pages }; so that when combined with the way Django looks for static files: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'frontend/dist/templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] STATICFILES_DIRS = [os.path.join(BASE_DIR, 'frontend/dist/static')] STATIC_URL = '/static/' the page will be able to load. Unfortunately, if I try to load the page, rather than loading at the website root /, it loads at /static/vue/ (i.e. localhost:8000/static/vue/). If I try to directly access localhost:8000, it immediately redirects to localhost:8000/static/vue/, which I suppose is vue-router's doing. Django is able to find the Vue entry point template just fine, but it seems to need publicPath: "/static/vue/" in order … -
