Get multiple radio button values from django template
My model contains passages and each passage have some questions and each question have four answers. I wrote a simple form to show the questions and showed the related answers with radio buttons, but I can't retrieve the answer for a specific question in Django View Django Template: <h2>Choose the right answer from the choices for any question</h2> <form action="{% url 'exam:submit' passage.id %}" method="post"> {% csrf_token %} {% for question in passage.question_set.all %} <h5>{{ forloop.counter }}-{{question.text }}</h5> {% for answer in question.answer_set.all %} <input type="radio" name="answer[{{ question }}]" id="answer{{ answer.id }}" value="{{ answer.id }}" /> <label for="answer{{ answer.id }}">{{ answer.text }}</label> <br/> {% endfor %} {% endfor %} <input type="submit" value="Submit" /> </form> Django View: def submit(request, passage_id): passage = get_object_or_404(models.Passage, pk=passage_id) if request.method == 'POST': answer_list = request.POST.getlist('answer') context = { 'List': answer_list, 'passage': passage, } return render(request, 'exam/submit.html', context) I want to show the list of answers that choose for their question in a list (e.g. [1, 2, 4, 3, 1] are the answers chosen for question 1, 2, 3, 4, 5), but the browser just shows an empty list (e.g. []). -
Custom Django decorator- whenever it is called, Django raises a circular import error
I'm trying to write a custom decorator for a Django view that is a lot like login_required, except it does something else when it finds that the user is not logged in. I initially put it in a custom.py file in the same directory as my views, but it returned a "circular import error" every time I tried to import it into the views. Then, I made it its own folder, and it returned the same error. As a last resort, I copied and pasted it into the django.contrib.auth.decorators folder. When I imported this entire file, it did not return the circular import error, but when I tried to call the decorator, it did. Why is it doing this? I checked the files and am sure I'm not making circular imports. Error: raise ImproperlyConfigured(msg.format(name=self.urlconf_name)) django.core.exceptions.ImproperlyConfigured: The included URLconf 'mysite.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. View imports: from django.shortcuts import render from django.views.decorators.http import require_http_methods import django.contrib.auth.decorators The decorator: def check_login(test_func): def decorator(view_func): @wraps(function) def _wrapped_view(request, *args, **kwargs): if test_func(request.user.is_authenticated): return view_func(request, *args, **kwargs) else: print("not written yet") return … -
Django middleware - exclude for specific path

Once i implement authentication system, it not works below is my settings.py REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ) } if i change into AllowAny in permisison, The test works nice but if keep IsAuthenticated instead of AllowAny , it not works. I want the test should run nicely even once i keep IsAuthenticated in permission. Can anyone suggest me how can i do it? I am not getting what to change or what add in my tests.py file. -
Python 3.7 / Django 2.2.1: Check field before save

Django project with custom user model load fixture error
I am setting up a new django(version 2.2) project and want to use custom user model. When I load fixtures data, it failed with error like below: django.db.utils.IntegrityError: Problem installing fixtures: insert or update on table "doctors_doctor" violates foreign key constraint "doctors_doctor_user_ptr_id_ba968804_fk_doctors_user_id" DETAIL: Key (user_ptr_id)=(1) is not present in table "doctors_user". From django document - https://docs.djangoproject.com/en/2.1/topics/auth/customizing/#using-a-custom-user-model-when-starting-a-project I realized I did 'python manage.py migrate' before changing AUTH_USER_MODEL in settings.py.

Following are my code settings.py AUTH_USER_MODEL='doctors.User' models.py class User(AbstractUser): mobile = models.CharField(max_length=30) fixtures_autodump = ['dev_users'] class Meta: db_table = 'doctors_user' def __str__(self): return self.username class Doctor(User): personal_id = models.CharField(max_length=255, blank=True) fixtures_autodump = ['dev_users'] class Meta: db_table = 'doctors_doctor' def __str__(self): return self.username dev_users.json [ { "model": "doctors.doctor", "pk": 1, "fields": { "date_joined": "2019-06-16T09:09:56.127Z", "email": "user1@localhost.dev", "first_name": "user1", "groups": [], "is_active": true, "is_staff": true, "is_superuser": true, "last_login": null, "last_name": "test", "password": "pbkdf2_sha256$36000$nITgYnD9lKzm$cXGlthNYJDrrihQikgyh7HO5hm2fNvH71+fiCoMyIpY=", "user_permissions": [] } }, { "model": "doctors.doctor", "pk": 2, "fields": { "date_joined": "2019-06-16T09:09:56.127Z", "email": "user2@localhost.dev", "first_name": "user2", "groups": [], "is_active": true, "is_staff": false, "is_superuser": false, "last_login": null, "last_name": "test", "password": "pbkdf2_sha256$36000$ohIbxnbyKjNm$smg+FvfhT1cF1kLt93EDz/n5KyfkDupIgkihsNIHQS8=", "user_permissions": [] } } ] I expect loading fixture data can be … -
How to deploy Django application using Django-background-tasks on AWS beanstalk?
I am using Django-background-tasks in my application, it worked fine for me on my local machine, I am trying to deploy the website to AWS elastic-beanstalk. I wanted to know how to mimic the 2 cmd prompt situation in windows( one with "python manage.py runserver" and the other with "python manage.py process_tasks") in AWS. This will be a kind of parallel situation where both commands need to run simultaneously. I tried adding the command as one of the container_commands in the config file in "./.ebextensions" but it didn't work (i consider AWS waits for such commands to end and it never ends, that's the case"). -

How to customize django-weasyprint view response
I would like to change a bit the behavior while generating pdf with django-weasyprint module. In my application, the objective is that the pdf is automatically saved then send it attached to an email. I built a CBV using the following class : class GeneratePDF(WeasyTemplateView): pdf_filename = 'resolutions_dj.pdf' template_name = 'polls/resolutions.html' def get(self, request, *args, **kwargs): context = self.get_context_data(**kwargs) return self.render_to_response(context) This works but shows me either the pdf or a dialog box to save the file. get_context_data() method is overriden but I do not think it has any importance. I would like to use this get() method to to more actions after rendering pdf. I tried this code but it does not work (no pdf generated, no dialog box) : class GeneratePDF(WeasyTemplateView): pdf_filename = 'resolutions_dj.pdf' template_name = 'polls/resolutions.html' def get(self, request, *args, **kwargs): context = self.get_context_data(**kwargs) response = self.render_to_response(context) return redirect('polls:event', event_slug=context['event'].slug) The key seems to be this line : response = self.render_to_response(context) I do not understand why it does not work. Finally, I found how to save pdf without showing it nor displaying a dialog box by overrinding rendered_content property (from WeasyTemplateResponse class) and adding response_class = PersoWeasyTemplateResponse in my GeneratePDF but it displays an empty pdf page … -

Overriding settings.py email settings in view
The email settings that are used by a post request need to depend on logic within my view. As a result, I'd like to overwrite the following email settings within my view, which are typically set in settings.py: settings.py EMAIL_HOST_USER = 'user@website.com' EMAIL_HOST_PASSWORD = '****************' DEFAULT_FROM_EMAIL = 'user@website.com' SERVER_EMAIL = 'user@website.com' Based on my reading (https://docs.djangoproject.com/en/2.1/topics/settings/#using-settings-without-setting-django-settings-module), I believe the best way to do this is as follows: views.py from django.conf import settings def myview(request): profile = ..logic that grab's user's profile... settings.configure(EMAIL_HOST_USER = profile.email) settings.configure(EMAIL_HOST_PASSWORD = profile.email_password) settings.configure(DEFAULT_FROM_EMAIL = profile.email) settings.configure(SERVER_EMAIL = profile.email) Can you confirm that this is the most appropriate way to do this? Thanks! -

How to lookup by field inherited from OneToOneField of another model
I am attempting to lookup UserProfile model using a field inherited from the User model. How can I access the username field from the User model in UserProfile view? I am using Django REST framework 3.9. And from my understanding, using the @property annotation in the Model definition allows you to serialize on that field. And I am using that serialized field as lookup_field in the view. This is the UserProfile model. class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField(max_length=500, null=True, blank=True) birth_date = models.DateField(null=True, blank=True) @property def username(self): return self.user.username This is the serializer. class UserProfileSerializer(serializers.ModelSerializer): class Meta: model = UserProfile fields = [ 'user', 'username', 'bio', 'birth_date' ] This is the view. class UserProfileAPIView(generics.RetrieveUpdateAPIView): # permission_classes = [permissions.IsAuthenticated] serializer_class = UserProfileSerializer lookup_field = 'username' def get_queryset(self): return UserProfile.objects.all() def get_serializer_context(self, *args, **kwargs): return {'request': self.request} This is the API url. path('<str:username>/profile/', UserProfileAPIView.as_view(), name='profile'), I expected the API to return: username, bio, birth_date but I received this error: "Cannot resolve keyword 'username' into field. Choices are: bio, birth_date, id, user, user_id". -

How do you list all object with the same foreign key object?
I have a Department model with a name field, then User model with department field using foreignkey to Department. How can I list in a template all users in a Department? Is there a way without using many to many? class Department(models.Model): name = models.CharField(max_length=64,unique=True) description = models.TextField(blank=True) def __str__(self): return self.name class User(AbstractUser): department = models.ForeignKey(Department, on_delete=models.CASCADE, blank=True,null=True) def __str__(self): return self.username
