How to control allowed methods in Django Rest Framework?
I've already seen a number of questions on this topic, but none of the answers seem to solve my issue. I have the following python modules: views.py: class MyObjectViewSet(viewsets.ModelViewSet): queryset = MyObject.objects.all() serializer_class = MyObjectSerializer permission_classes = [permissions.AllowAny] # For testing @action(methods='POST', detail=True) def my_request(self, request, *args, **kwargslf): # Do stuff urls.py: router = routers.DefaultRouter() router.register(r'myobject', views.MyObjectViewSet) urlpatterns = [ path('', include(router.urls)), path('api-auth/', include('rest_framework.urls', namespace='rest_framework')) ] When I try to make an actual POST-request to the my_request-route, I get Method POST not allowed. But as I understand, ModelViewSet should allow all methods. Even if I include http_method_names = ['get', 'post', 'patch', 'put', 'head', 'delete'] in my view, it still doesn't work. -

Is the a Django serializer to serialize reverse relations individually?
I have these two models, where A has a many-to-one relation with B: class A(models.Model): field_A1 = models.ForeignKey('B', ...) field_A2 = ... class B(models.Model): field_B = ... #primary key I know I can setup a serializer for B to also serialize the related instances of A, taking advantage of .a_set. For instance, if I tried to serialize an instance of B having two related instance of A I would get something like the following: { "field_B": "instance of B", "a_set": [ { "field_A2": "first related instance of A" }, { "field_A2": "second related instance of A" } ] } What I want the serialize to output instead is the 'product' of instance of B with the related instances of A, e.g. in the same scenario as in the previous example, I would like to get the following: [ { "field_B": "instance of B", "field_A": "FIRST related instance of A" }, { "field_B": "instance of B", "field_A": "SECOND related instance of A" } ] How can I obtain this in Django? Do I need to populate a data structure with the product myself or there's something built-in in the framework I can use? -

Specify database inspectdb in django
Is there any way how can I inspectdb specific database in Django. I've been open new connection and then I want to inspectdb under matchyv3_revamp. How do I specify matchyv3_revamp in inspectdb?

Using middleware class for user authentication in Django project
One of my company's project is in Django and I was assigned to a task to 'add authentication to the top-level router' so we don't forget to add an authentication code to every view, such as: if not request.user.is_authenticated: return HttpResponseRedirect('/admin/login/?next=/admin/some-page/') After doing a bit of research I found out that this can be accomplished by writing my own middleware. I was not familiar at all with the concept until doing my homework. So now I am trying to write a LoginRequiredMiddleware class that intercepts every request and sends the user to the login page if not authenticated and, after authentication, to the original page the user was trying to access. This is the code I have so far. middleware.py from django.conf import settings from django.http import HttpResponseRedirect from django.utils.deprecation import MiddlewareMixin from django.utils.http import is_safe_url import re EXEMPT_URLS = [re.compile(settings.LOGIN_REDIRECT_URL.lstrip('/'))] # '/admin' class LoginRequiredMiddleware(MiddlewareMixin): def process_request(self, request): assert hasattr(request, 'user'), "The Login Required Middleware" if not request.user.is_authenticated: path = request.path_info.lstrip('/') if not any(m.match(path) for m in EXEMPT_URLS): redirect_to = settings.LOGIN_REDIRECT_URL if len(path) > 0 and is_safe_url( url=request.path_info, allowed_hosts=request.get_host()): redirect_to = f"{settings.LOGIN_REDIRECT_URL}/login?next={request.path_info}" return HttpResponseRedirect(redirect_to) I have already registered the middleware in the MIDDLEWARE list in settings.py and included both SessionMiddleware … -
Django Rest Framework - ImageField - use default value if no image is provided
I am sending a POST request with Axios using FormData that contains an individual image and also a list of images, like this: React State: "thumbnail": thumbnailImage, "gallery": [ galleryImage0, galleryImage1, galleryImage2 ] FormData: formData.set("thumbnail", this.state.thumbnail); for (let image of document.querySelector("#gallery").files){ formData.append("gallery", image); } Note: this part is probably fine, as the problem persists even when using Postman to craft the request In Django, using DRF I can perfectly deserialize this data if there are actual images sent, but if for example the "thumbnail" does not contain a file (user did not choose a file), I get the following: [ErrorDetail(string='The submitted data was not a file. Check the encoding type on the form.', code='invalid')] What I actually want is to use the default provided in the model, which looks like this: class Item_ThumbnailImage(models.Model): image = models.ImageField(upload_to=hash_image_thumbnail, default='items/no-image.gif', blank=True) belongs_to = models.ForeignKey( 'Item', related_name='thumbnail', on_delete=models.CASCADE) I get the data ready this way: thumbnail_data = { 'belongs_to': item.id, 'image': request.data.get("thumbnail") } Here's the deserialization: thumbnail = Item_ThumbnailImageSerializer(data=thumbnail_data) if thumbnail.is_valid(): thumbnail.save() else: print(thumbnail.errors) Serializer: class Item_ThumbnailImageSerializer(serializers.ModelSerializer): class Meta: model = Item_ThumbnailImage fields = '__all__' I have tried this in the serializer: image = serializers.ImageField(required=False, allow_empty_file=True, allow_null=True) ...along with this: thumbnail_data = { 'belongs_to': … -

Django - Reset a save variable to 0, preferably at home view
I'm creating a simple quiz (99% done), just need help with one last thing - probably trivial to intermediate/advanced programmers. I have created a save variable to save the user's current score. This is so that the user navigates from page to page and can still see their current score. As the user navigates last template view, it gives the final score and a link to redirect to the homepage. This allows the user an opportunity to "retake the quiz". At this moment (home page) I need help to reset the saved score variable to 0. Please let me know how I can do this, thanks in advance! models.py class Scorer(models.Model): score = models.IntegerField(default=0) page = models.IntegerField() condition_number = models.IntegerField(default=0) views.py def vote(request, question_id, *args, **kwargs): model = Question template_name = 'quizzes/vote.html' question = get_object_or_404(Question, pk=question_id) ### To create user scoring system ### scorer, created = Scorer.objects.get_or_create(page=1) try: selected_choice = question.answer_set.get(pk=request.POST['answer']) ### To save user score ### if selected_choice in Answer.objects.filter(id=1): scorer.score +=10 scorer.save() elif selected_choice in Answer.objects.filter(id=6): scorer.score +=10 scorer.save() elif selected_choice in Answer.objects.filter(id=12): scorer.score +=10 scorer.save() elif selected_choice in Answer.objects.filter(id=13): scorer.score +=10 scorer.save() elif selected_choice in Answer.objects.filter(id=19): scorer.score +=10 scorer.save() elif selected_choice in Answer.objects.filter(id=22): scorer.score +=10 scorer.save() elif … -

Django DRF calling ModelSerializer with model object as dict throws 'object has no attribute RelatedManager'
I'm trying to call a ModelSerializer named RegistrationSummarySerializer with my model object. When I'm trying to insert the object directly it throws Invalid data.

Is it feasible to create an extra field that indicates the number of related entries to be searched in another table?
My goal is to get the best compromise between space and performance for the situation. I have two similar situations but they differ slightly. Situation 1: Suppose I have two tables for a classic situation: 'survey' and 'question'. class Survey(models.Model): survey_owner_id = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) survey_title = models.CharField(max_length=70, blank=False, null=False) class Question(models.Model): survey_id = models.ForeignKey(Survey, on_delete=models.CASCADE, blank=True) question = models.TextField(max_length=150, null=False, blank=True) One survey can have up to 10 questions, but may also have fewer, but must have at least 5. I am pondering whether it would be feasible to add another field to the 'survey' table that indicates the number of questions that this survey has, and therefore, the number of rows that will need to be queried in the 'question' table, so that not the entire table needs to be queried from start to end, each time the survey is pulled up. In this case, a survey will likely not be pulled up as frequently. For example: class Survey(models.Model): survey_owner_id = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) survey_title = models.CharField(max_length=70, blank=False, null=False) question_amount = models.IntegerField(blank=False, null=False) Situation 2: Suppose a similar situation as in the survey-question example, but in this case, the survey can only have up to 4 questions (but may also … -
Conditional formatting Bootstrap cards in Django
I am building a Django template using Bootstrap 4. I'm looking at formatting the badges based on a categorical field from my Project model (for example, if category is "Complete", I'd like the badge to be green).

Below is my Django template (which currently leverages default Bootstrap colors / formats). {% if project.status == "complete" %} <span class="badge rounded-pill bg-success text-light">{{ project.status|title }}</span> {% elif project.status == "review" %} <span class="badge rounded-pill bg-active text-light">{{ project.status|title }}</span> {% elif project.status == "autopilot" %} <span class="badge rounded-pill bg-light text-dark">{{ project.status|title }}</span> {% elif project.status == "issues" %} <span class="badge rounded-pill bg-warning text-dark">{{ project.status|title }}</span> {% elif project.status == "submitted" %} <span class="badge rounded-pill bg-dark text-light">{{ project.status|title }}</span> {% elif project.status == "draft" %} <span class="badge rounded-pill bg-info text-light">{{ project.status|title }}</span> {% endif %} Things that I've been thinking about but there must be something simpler or more straightforward: Create a new model attribute for formatting only (possibly derived from the categorical attribute). … -

How to save URL to a Django ImageField
I have Django model with Image field, but sometimes I don't need to actually upload file and store path to it, but I need to store only path. Especially url. I mean, I have web client, that receives both foreign urls like sun1-17.userapi.com and url of my own server, so sometimes I don't need to download but need to store url. Is it possible, to store url in ImageField, or I need to make CharField and save files via python? If its impossible, how do I save file in python3, having one, sent me via multipart?
