Assertion error parsing response to POST request from DRF viewset with DRF APIClient in tests
I've run into a strange issue with Django Rest Framework testing engine. The weird thing is that everything used to work fine with Django 3 and this issue turned up after I migrated to Django 4. Apart from testing, everything works well, and responds to queries as expected. The problem I'm using DRF APIClient to make queries for unit tests. While GET requests perform predictably, I fail to make POST requests work. Here is some minimalistic example code I created to figure out the issue. The versions I'm using: Python 3.9 Django==4.0.3 djangorestframework==3.13.1 from django.db import models from django.urls import include, path from django.utils import timezone from rest_framework import routers, serializers, viewsets router = routers.DefaultRouter() # models.py class SomeThing(models.Model): created_at = models.DateTimeField(default=timezone.now) title = models.CharField(max_length=100, null=True, blank=True) # serializers.py class SomeThingSerializer(serializers.ModelSerializer): class Meta: fields = "__all__" model = SomeThing # views.py class SomeThingViewSet(viewsets.ModelViewSet): queryset = SomeThing.objects.all().order_by('id') serializer_class = SomeThingSerializer # urls.py router.register("some-things", SomeThingViewSet, basename="some_thing") app_name = 'question' urlpatterns = ( path('', include(router.urls)), ) Here is my test case: import json from django.contrib.auth import get_user_model from rest_framework import status from rest_framework.test import APITestCase, APIClient class TestUserView(APITestCase): self.some_user = get_user_model().objects.create(login="some_user@test.ru") @staticmethod def get_client(user): client = APIClient() client.force_authenticate(user=user) return client def test_do_something(self): client … -
How to create multiples request in Django
I want to receive a request.POST values N times, where N is a number entered by the user. The views.py is: def valores(request): global peso_unitario, preco_unitario peso_unitario = [] preco_unitario = [] N = a print('N=' + str(N)) for i in range(N): form = Form(request.POST) c = int(request.POST.get('peso_u')) d = int(request.POST.get('preco_u')) peso_unitario.append(c) preco_unitario.append(d) return render(request, 'valores.html') return render(request, 'pacote_m.html', {'peso_unitario': peso_unitario, 'preco_unitario': preco_unitario}) In this code in the end I have two returns, where the first is inside the for loop because I want to receive the values N times and return them to the template valores.html. The last return is in the end, after the for loop will redirect to a new template, this template pacote.html will show the values calculated according to I programmed, but it isn't the problem. The template valores.html is: {% extends 'basic.html' %} {% block content %} <form action="page2" method="GET"> {% csrf_token %} <h1>Digitados:</h1> numero de objetos={{n_objetos}}<br> peso peso maximo={{peso_maximo}}<br> <!--- Peso unitario: <input type="text" name="peso_u"><br><br> Preco unitario: <input type="text" name="preco_u"><br><br> ---> <table> <thead> <tr> <th>Peso unitario</th> <th>Preco unitario</th> </tr> </thead> <tbody> <tr> <td><input type="text" name="peso_u"></td> {{form.peso_u}} <td><input type="text" name="preco_u"></td> {{form.preco_u}} </tr> </table> <input type="submit"> </form> {% endblock %} My forms.py is: class Form(forms.Form): … -
How to mix the order of items of a Django object on a page?
I am trying to create a game that allows users to play a quiz, which is stored as a Django object, but I want the order of the questions to be different (as in random) every time. Is there a way to accomplish this? models.py class Quiz(models.Model): user = models.ForeignKey(Profile, on_delete=models.CASCADE, default="") title = models.TextField(default="") question1 = models.TextField() answer1 = models.TextField() question2 = models.TextField() answer2 = models.TextField(default="") question3 = models.TextField() answer3 = models.TextField() ... (The questions and answers go to 10.) views.py def quiz(request, quiz_id): quiz = get_object_or_404(Quiz.objects, pk=quiz_id) return render(request, "capstone/quiz.html", { "quiz": quiz }) I was thinking about generating a random number, but I think that would be too complicated with the number of questions. Is there any easier way to randomly display the questions to the user? -
jinja2 emplateNotFound (but file exists)
In one of my views in Django 4.0 I want to render a summary of lesson with Jinja2. Even though a template exists for sure in good location I get jinja2.exceptions.TemplateNotFound which is very confusing. views.py: from jinja2 import Environment, FileSystemLoader def generate(request): if request.method == 'POST': ... var1 = "foo" var2 = "bar" var3 = 123 BASE_DIR = Path(__file__).resolve().parent.parent templatesPath = str(BASE_DIR) + '/static/tex/' fileSystemLoader = FileSystemLoader(templatesPath) env = Environment(loader = fileSystemLoader) renderedLatex = env.get_template(templatesPath + 'lesson_template.tex').render(pvar1, var2, var3) After calling the view the output is: jinja2.exceptions.TemplateNotFound: /home/user1/Projects/Dramath/Dramath-Project/static/tex/lesson_template.tex Just to be sure there is no typo I copied full path to the template file and compared it with the above - both paths are the same. For a quick test I tried to relocate lesson_template.tex in project root directory but it didin't do much. Any ideas where might be issue? -
How to show answers based on the certain question Django?
I'm writing a site where users can ask questions. I don't understand what problem is in my code, but when I'm trying to show all answers on certain question - nothing appears on the screen. I tried to use everything: QuerySet with filter, get, using id, but nothing works. Seems like problem in two thing: Django doesn't understand what answers to show or my template is incorrect. Here is the code: models.py class Question(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=250) slug = models.SlugField(max_length=255, unique=True, db_index=True, verbose_name="URL") detail = models.TextField() date_posted = models.DateTimeField(default=timezone.now) def __str__(self): return self.title def get_absolute_url(self): return reverse('detail', kwargs={'slug': self.slug}) class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) detail = models.TextField() date_posted = models.DateTimeField(default=timezone.now) def __str__(self): return self.detail urls.py urlpatterns = [ path('', QuestionView.as_view(), name='forum'), path('search/', SearchView.as_view(), name='search'), path('question/<slug:slug>/', QuestionDetailView.as_view(), name='detail'), path('answer/', AnswerView.as_view(), name='answer') ] views.py class QuestionView(ListView): model = Question template_name = 'forum/forum.html' context_object_name = 'questions' ordering = ['-date_posted'] paginate_by = 1 class QuestionDetailView(DetailView): model = Question template_name = 'forum/detail.html' class AnswerView(ListView): model = Answer template_name = 'forum/detail.html' context_object_name = 'answers' def get_queryset(self): quest = Question.objects.get(id=1) return Answer.objects.filter(question=quest) templates/detail.html {% for answer in answers %} <div class="col-11"> <p>{{ answer.detail }}</p> <p><a href="#" class="mr-3">BigBossData</a><span>5 комментариев</span></p> </div> {% endfor %} -
viewing UserDetail template causes user to switch
I have a simple Group model: class Group(models.Model): leader = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=55) description = models.TextField() joined = models.ManyToManyField(User, blank=True) In the DetailView for every Group other Users have the ability to see who has joined and also to check out the User's profile: {% extends 'base.html' %} <ul> {% for member in group.joined.all %} <li><a href="{% url 'user_detail' member.id %}">{{ member }}</a></li> {% endfor %} </ul> This works but with a slight catch. When I click on the link and go to that User's DetailView, suddenly I'm signed in as them. But only on that page it seems because when I go back to my home page, I'm suddenly signed back in as the original User. To be more clear, when I (as the User 'admin') go and click on another User link, I'm brought to the correct UserDetail view: <h6>{{user.username}}</h6> <div>Username: {{user.username}}</div> <div>Email: {{user.email}}</div> <div>First: {{user.first_name}}</div> <div>Last: {{user.last_name}}</div> <div>Groups Joined: {% for group in user.account.joined_group.all %} <a href="{% url 'group_detail' group.pk %}">{{group}}</a> {% endfor %} </div> <div>Groups Created: {% for group in user.account.created_groups.all %} <a href="{% url 'group_detail' group.pk %}">{{group}}</a> {% endfor %} </div> {% if user.is_authenticated and user.id == user.account.id %} <a href="{% url 'update_user' … -

ModuleNotFound Error when trying to import variable from script
I have a python script named "WhatsApp_to_Excel.py". There is a variable there that I need to use for a Django project I'm making. So I'm trying to import the module to the models.py file. This is my folder hierarchy- Then I make my import like this- But even though pycharm auto-completed the module's name, when I run the server I get the no module found error. I'm running my code from a virtual environment, but I don't see how this can be the problem. I've tried to import the module in an absolute way, but it didn't work and it's rather weird that pycharm DOES recognize the module. Does anybody Have any ideas on how to solve the problem? Would appreciate any help :-) -
How to get or show every object from newest to latest in Django
I'm pretty new to python and django. I was able to create an simple CRUD logic with template, but i'm getting a small problem. When i update a specific task and then querrying all object from a model, the one that was updated is now querried on the last position (views.py below): def create_task(request): tasks = Task.objects.all() if request.method == 'POST': task_id_update = request.POST.get('task_id_update') task_id_delete = request.POST.get('task_id_delete') if task_id_update: task = Task.objects.filter(id=task_id_update).first() task.finished = True task.save() elif task_id_delete: task = Task.objects.filter(id=task_id_delete).first() task.delete() else: form = TaskForm(request.POST) if form.is_valid(): task = form.save(commit=False) task.author = request.user task.save() return redirect('/create_task') form = TaskForm() return render(request, 'main/create_task.html', {'form': form, 'tasks': tasks}) And i want to render it on a ONE-PAGE like template, and this is what i did in my html: <table class="table table-hover"> <thead> <tr> <th scope="col">Title</th> </tr> </thead> <tbody> {% for task in tasks %} {% if task.finished == False %} <tr> <td>{{task.title}}</td> <td> <form method="post"> {% csrf_token %} <button type="submit" class="btn btn-warning" name= "task_id_update" value="{{task.id}}">Mark as finished</button> </form> </td> <td> <form method="post"> {% csrf_token %} <button type="submit" class="btn btn-danger" name= "task_id_delete" value="{{task.id}}">Delete</button> </form> </td> </tr> {% else %} <tr class="table-success"> <td>{{task.title}}</td> <td> <form method="post"> {% csrf_token %} <button type="submit" class="btn btn-danger" … -
Forcing evaluation of prefetched results in django queries
I'm trying to use select_related/prefetch_related to optimize some queries. However I have issues in "forcing" the queries to be evaluated all at once. Say I'm doing the following: fp_query = Fourprod.objects.filter(choisi=True).select_related("fk_fournis") pf = Prefetch("fourprod", queryset=fp_query) # products = Products.objects.filter(id__in=fp_query).prefetch_related(pf) With models: class Fourprod(models.Model): fk_produit = models.ForeignKey(to=Produit, related_name="fourprod") fk_fournis = models.ForeignKey(to=Fournis,related_name="fourprod") choisi = models.BooleanField(...) class Produit(models.Model): ... ordinary fields... class Fournis(models.Model): ... ordinary fields... So essentially, Fourprod has a fk to Fournis, Produit, and I want to prefetch those when I build the Produits queryset. I've checked in debug that the prefetch actually occurs and it does. I have a bunch of fields from different models I need to use to compute results. I don't really control the table structure, so I have to work with this. I can't come up with a reasonable query to do it all with the queries (or using raw), so I want to compute stuff python-side. It's a few 1000 objects, so reasonable to do in-memory. So I cast to a list to force the query evaluation: products = list(products) At this point, I would think that the Products and the related objects that I have pre-fetched should have been fetched from the DB.

Editable comments django blog
I'm having trouble making my comments editable. They work fine if I leave them uneditable, but I do want them editable.

Django Template, how to parse items with symbols

State is being cleared on page reload
I am building a web site using Django and React and I just realized I've got this problem. Basically every time I log in to my page, while not refreshing everything is okay, my state is persistent and my user stays logged in.

When I do that, my local storage persists but my state doesn't.

How should I be storing query parameters for saved searches in web app? (best practices)
I have a web app that displays articles and each article has several fields all searchable with parameters and they have many to many and many to one relationships . There are several places in my database that store these parameters for something like a saved search or permissions to allow a user to only view certain articles. These parameters are stored as strings, or python query objects, or json objects. The problem is that when one of the names of the parameters changes, the query object, json object, or string isn't updated. So for example, if a article is published by 'U.S. Department of Justice', then a user saves a search with that agency, when we change the name of the agency (lets say there's a misspelling in the name), the search will not find that agency unless we go in an update the stored string object manually. This seems incorrect, but I'm not sure what the correct way is. Is there a best practices for something like this? Should the parameters be stored in a table with object references so that things like name changes are unaffected? OR do I just have to go into these strings and … -
