Format warning in unit test as a import of customized app comes after loading settings
In a Django project's unit test, we need to configure the settings to direct to ourapp by INSTALLED_APPS and to prevent the below run-time error: django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. The line of from ourapp.rest.views import retrieve_timerange gets a formatting warning saying PEP 8: E402 module level import not at top of file. However, the import line depends on the INSTALLED_APPS of the settings, so it must come after the configuration action above. I wonder if there is an elegant way to resolve this formatting issue. Sample source code of the unit test: import os import django from django.conf import settings import unittest from unittest import TestCase os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ourproject.settings") django.setup() from ourapp.rest.views import retrieve_timerange class TestViews(TestCase): def setUp(self): ... def __run_get_test(self): ... -
django: m2m field may not be empty
Students can be assigned to many groups. One student can be assigned to many groups One Group can hold many students. With code below I can create Student with no group or assigned to some groups. I can change everything with success, exept... Exept that I can not remove all groups assigned to student. I assume that some student can unsubscribe from all groups. But django don't like that and throw error: {'groups': [ErrorDetail(string='This list may not be empty.', code='empty')]} Code: Models: class Group(models.Model): group_name = models.CharField(max_length=30, unique=True, null=True, blank=True) class Student(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) groups = models.ManyToManyField(Group) Create Student: new_student = Student.objects.create( first_name = request.data["first_name"], last_name = request.data["last_name"], ) groups_id = request.data["group_id"] if(groups_id): for group_id in groups_id: new_student.groups.add(group_id) Change Student: def change_student(request, id): student_to_change = Student.objects.get(id=id) serializer = StudentSerializer( instance=student_to_change, data={ 'first_name': request.data["first_name"], 'last_name': request.data["last_name"], 'groups': request.data["groups"], } ) if serializer.is_valid(): serializer.save() And when I try to execute change_student with for example: request.data : {'id': 16, 'first_name': 'John', 'last_name': 'Smith', 'groups': []} I get {'groups': [ErrorDetail(string='This list may not be empty.', code='empty')]} error And serializers: class GroupSerializer(ModelSerializer): class Meta: model = Group fields = '__all__' class StudentSerializer(ModelSerializer): class Meta: model = Student fields = '__all__' -
Django-tables2: How to ensure consistent ordering when sorting?
When sorting the table by clicking on a header, if there are rows that have the same value, the order can not be consistent from one query to another. Is there a way to specify a "secondary" sorting criteria? For example, when user clicks on the price header to sort rows by price, behind the scene I'd like to have ordering = (price, pk) sothat the result is guarantee to be the same, given the same queryset. For now, I succeeded with price = tables.Column(order_by=["price", "id"]). However, doing this for every column is tedious, there must be a better way. Thanks. -
Re-usability of code between django and django rest framework
I have been assigned a project which has two versions of it: older one is written in django and new one written in django rest framework. I am quite new to both django and drf. While going through both codebase, I came across following code in one of the views.py in new drf version: def get_xyz(request): # some business logic return HttpResponse(json.dumps({ ... }) , content_type="application/json" , status=status.HTTP_200_OK) Then in older version of the app, I found function with exactly same above structure in its views.py. This created following confusions in me: Can we use function based views (as above) written in (non-drf) django app as it is in drf based app? Can we use class based views (as shown below) from non-drf django app as it is in the drf based app? class AbcClass(View): def get(self, request): # business logic return HttpResponse(json.dumps({ ... }) , content_type="application/json" , status=status.HTTP_200_OK) def post(self, request): # business logic return HttpResponse("success", status.HTTP_200_OK) Does all django framework (non-rest) classes (like View above) work perfectly in drf? Can we make frontend app written in react (or angular) send requests and receive responses from old django app (similar to how frontend apps built with these UI frameworks … -
Why can't I filter the data by one known in django&
I have a painted filter in view.py which works wonderfully. When I use a common abbreviation in html code, like {{form.as_p}} or {{form|crispy}}, then I can find the data I need, according to one known one. In my case, this is by course, by semester, by type of subject, by institute, and so on, and when I start writing my html code, in order for the search to give the correct answer, all fields must be filled in, although in forms and models I determined that all fields are not required, it turns out that an error in the html code, but I do not know where( veiws.py: def buy_files(request): bdfiles = FeedFile.objects.all() # bdfiles = UploadFile.objects.all() form = FileFilterForm(request.GET) if form.is_valid(): if form.cleaned_data["number_course"]: bdfiles = bdfiles.filter(feed__number_course = form.cleaned_data["number_course"]) if form.cleaned_data["number_semestr"]: bdfiles = bdfiles.filter(feed__number_semestr = form.cleaned_data["number_semestr"]) if form.cleaned_data["subjectt"]: bdfiles = bdfiles.filter(feed__subjectt = form.cleaned_data["subjectt"]) if form.cleaned_data["type_materials"]: bdfiles = bdfiles.filter(feed__type_materials = form.cleaned_data["type_materials"]) if form.cleaned_data["institute"]: bdfiles = bdfiles.filter(feed__institute = form.cleaned_data["institute"]) return render(request, 'chat/files/buyfile.html', {'bdfiles': bdfiles, 'form':form}) html code: <div style="float: right; margin-bottom: 10%; margin-top: 10%;" class="form-group row" data-aos="fade-up"> <form action="" method="get" style="width:90%"> {% csrf_token %} <!-- {{form|crispy}}--> <p><label class="form-label">Курс: </label> {{ form.number_course }}</p> <div class="form-error">{{ form.number_course.errors }}</div> <p><label class="form-label">Семестр: </label> {{ form.number_semestr }}</p> … -

Authorization header is not sending when using Swagger documentation on drf-spectacular
I'm using drf-spectacular to document and test my endpoint. My code look like this: @extend_schema( parameters=[ OpenApiParameter(name='Authorization', description='Authorization token', required=True, type=str, location=OpenApiParameter.HEADER), OpenApiParameter(name='my-key1', description='My key 1 info', required=True, type=str, location=OpenApiParameter.HEADER), OpenApiParameter(name='my-key2', description='My key 2 info', required=True, type=str, location=OpenApiParameter.HEADER), ], description='Info about the endpoint', responses={ 200: inline_serializer( name='Successfull response', fields={ "result_code": serializers.IntegerField(default=200), "result_description": serializers.CharField(default="Transaccion Exitosa"), "data": DocumentSerializer(many=True), } ), }, ) @api_view(["GET"]) def my_endpoint_function(request): pass As you can see I'm declaring 3 headers parameters, Authorization, my-key1 and my-key2. But when I try to use the Swagger documentation only my-key1 and my-key2 are sending. Here's an example: As you can see in the Swagger documentation I'm sending the three headers I mentioned above, but in the curl only two of them are sending. Does anyone know how to fix this? I need to test my endpoints in the documentation. Thank you for your time. -
Django REST framework: error in HTML form in browsable API
I have this model: class WeaponClass(models.Model): """Table with all possible weapon classes.""" label = models.CharField(max_length=32) acronym = models.CharField(max_length=8) class Meta: ordering = ['id'] verbose_name_plural = 'weapon classes' def __str__(self): return f"{self.label}, {self.acronym}" with this serializer: class WeaponClassSerializer(serializers.HyperlinkedModelSerializer): url = serializers.HyperlinkedIdentityField(view_name="weapon_classes-detail") class Meta: model = WeaponClass fields = ['url', 'label', 'acronym'] Now, I have player, that has weapon class: class PlayerSerializer(serializers.HyperlinkedModelSerializer): url = serializers.HyperlinkedIdentityField(view_name="players-detail") user = UserSerializer() weapon_class = WeaponClassSerializer() class Meta: model = Player fields = ['url', 'user', 'weapon_class'] When I display player, everything is working perfectly how I want it, except for one thing. When I view browsable API from django rest framework, Weapon Class name in HTML form is outputting <BoundField value=Medium Bruiser errors=None>. It should output 'Weapon Class', just like the part with 'User'. When I open Weapon Class, title on that page is normal, it says 'Weapon Class Instance', same as 'Player Instance' in pictures below. Its not affecting anything, but I'm really wondering why is it doing this: I circled the problem. -

Import Error When Running Django From Windows

Form is getting wrong instance
I have a view where I list a bunch of child objects belonging to the parent object. Each child's object has a form in the template where they can update their feeling. However, the instance of the form is not showing the correct value. The view looks like this right now: def child_page(request, pk=None): parent = Parent.objects.get(pk=pk) children = Children.objects.filter(parent=parent, user=request.user) form = ChildForm(request.POST or None) if request.POST: child_id = request.POST.get('child_id', None) child_feeling = request.POST.get('feeling') child.feeling = child_feeling child.save() return redirect('index') context = { 'children': children, 'form': form } return render(request, 'test.html', context) I tried to for loop through the child objects and giving the instance like this: for x in children: print(x) form = ChildForm(request.POST or None, instance=x) Which did neither work. The output of the print is all the existing objects. I can't understand why this is happening. With this method, the last elements instance is being showed in all elements instance. How should I get the instance of a single child object and pass it in as the instance, so that each form shows the instance belonging to the child object that is trying to be updated? -

Django REST Framework | many-to-many relation returning "detail: not found"
I'm using Django REST framework. I've created a model for items in an inventory system and also a through table (named subassembly) for many-to-many relationship between items themselves, so an item can be a subpart of other items and vice versa. I'm just not sure I've done it right and I can't seem to get any results. When I visit the backend at a URL such as http://localhost:8000/api/subassemblies/2/, the response is {"detail": "Not found."} but I'm hoping to see all of an item's subparts, or "children". PUT or any other type of request has the same outcome. If it matters, when accessing the subassemblies from the admin page, I can create relationships between items just fine. But only one at a time though. And I need to be able to edit all of an item's subparts in one go (at least, frontend-wise). Currently, the request body is structured like so: { "parent_id": 2, "children": [ { "child_id": 5, "qty": 2 }, { "child_id": 4, "qty": 3 }, ] } This also allows me to use .set() on a particular items children which is useful because I think it also removes any prior children that are not included in the new … -

I need every use link to be checked, for e.g. if the user has no followers, turn the number to 0, and if it has no followings, turn it back to 0. it works fine for certain users, but creates issues with some other ones, I will put my code below. *UserFollowing is a model which determines who follows who. models: `class UserFollowing(models.Model): user = models.ForeignKey(User, related_name="following",on_delete=models.CASCADE) following_user= models.ForeignKey(User, related_name="followers",on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True)` URLS: from django.urls import path from . import views from.views import CreatePost urlpatterns = [ path('explore/', views.Listexplore.as_view(), name='page-explore'), path('user/<str:username>/', views.UserList.as_view(), name='user-posts'), path('post/<int:pk>/', views.DetailPost.as_view(), name='post-detail'), path('post/<int:pk>/update/', views.UpdatePost.as_view(), name='post-update'), path('post/<int:pk>/delete/', views.DeletePost.as_view(), name='post-delete'), path('post/create/', CreatePost.as_view(), name='post-create'), path('about/',views.about,name='page-about'), path('home/',views.Listhome.as_view(),name='page-home'), path('tests/',views.test,name="page-test"), ] view: def post(self, request,**kwargs): user2 = get_object_or_404(User, username=self.kwargs.get("username")) try: UserFollowing.objects.get(following_user=user2, user=request.user) created = UserFollowing.objects.get(following_user=user2, user=request.user) created.delete() request.user.profile.follower -= 1 user2.profile.following -= 1 request.user.save() user2.save() except UserFollowing.DoesNotExist : created = UserFollowing.objects.create(following_user=user2, user=request.user) request.user.profile.follower += 1 user2.profile.following += 1 created.save() request.user.save() user2.save() return redirect(request.META['HTTP_REFERER']) def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get("username")) return post.objects.filter(author=user).order_by("-time") def get_context_data(self, **kwargs): context = super(UserList, self).get_context_data(**kwargs) context['user2'] = get_object_or_404(User, username=self.kwargs.get("username")) my_user= User.objects.get(username=self.request.user.username) try: UserFollowing.objects.get(following_user=context['user2'], user=my_user) follow=True except UserFollowing.DoesNotExist : follow=False context['follow']=follow return context the middleware i wrote: … -

How to correctly configure Gmail to send E-mail with Django. The official configuration does not work for me

And this is the method to send the E-mail. I am using EmailMessage but with send_mail the result is the same: def contact(request): contact_form = ContactForm() if request.method == 'POST': contact_form = ContactForm(data = request.POST) if contact_form.is_valid(): name = request.POST.get('name', '') email = request.POST.get('email', '') content = … -
