How do I convert a blob file passed through rest to imagefield django?
My web application receives an image via the api in blob format(it is cropped there by the user) and I need to accept it, convert it to imagefield and save it to the user. I wrote this code in the serializer, nothing changes and the value of variables I also do not see(whether validated_data is exactly in this format as I think). serializers.py: class ProfileSerializer(serializers.ModelSerializer): # image = serializers.ImageField(use_url=True) class Meta: model = User fields = ["first_name", "last_name", "email", "image"] def create(self, validated_data): user = User.objects.get(email=validated_data['email']) user.update(**validated_data) with io.BytesIO(validated_data['image']) as stream: django_file = File(stream) user.image.save('{}_profile_image'.format(user.email), django_file) return user.save() views.py: class UserProfile(generics.RetrieveUpdateDestroyAPIView, generics.CreateAPIView): queryset = User.objects.all() serializer_class = ProfileSerializer permission_classes = (IsAuthenticated,) def get_object(self): queryset = self.filter_queryset(self.get_queryset()) obj = queryset.get(pk=self.request.user.id) # May raise a permission denied self.check_object_permissions(self.request, obj) return obj def create(self, request, *args, **kwargs): if not request.data: return response.Response({"result": "data can`t be a blanks"}, status.HTTP_400_BAD_REQUEST) serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) self.perform_create(serializer) return response.Response(serializer.data, status=status.HTTP_201_CREATED) -
Django REST - JSON gets returned with backslashes (serilized mutpiple times?)
I have defined the following function in the backend for getting JSON responses def create(self, request, *args, **kwargs): import requests import json url = request.POST.get('url') r = requests.get(url) return Response(json.loads(r.content.decode('utf-8'))) It works perfectly when used outside of a django view (if i remove all the function arguments and pass in a url) This is the output when sending a sample request to the Twitter API { "url": "https://twitter.com/elonmusk/status/1285830270709403648", "author_name": "Elon Musk", "author_url": "https://twitter.com/elonmusk", "html": "<blockquote class=\"twitter-tweet\"><p lang=\"en\" dir=\"ltr\">You don’t have a soul, you are a soul</p>&mdash; Elon Musk (@elonmusk) <a href=\"https://twitter.com/elonmusk/status/1285830270709403648?ref_src=twsrc%5Etfw\">July 22, 2020</a></blockquote>\n<script async src=\"https://platform.twitter.com/widgets.js\" charset=\"utf-8\"></script>\n", "width": 550, "height": null, "type": "rich", "cache_age": "3153600000", "provider_name": "Twitter", "provider_url": "https://twitter.com", "version": "1.0" } No only do the strings get wrapped in double quotes \ \ but also arguments like \n , blockquote are kept in the response I know it has something to do with the response beeing serialized multiple times but I can't find exactly when this happens Slightly Modifying the response to return the raw data returns this return Response({ "json_serialized" : json.loads(r.content.decode('utf-8')), "raw_content" : r.content.decode('utf-8') }) Here is the output { "json_serialized": { "url": "https://twitter.com/elonmusk/status/1285830270709403648", "author_name": "Elon Musk", "author_url": "https://twitter.com/elonmusk", "html": "<blockquote class=\"twitter-tweet\"><p lang=\"en\" dir=\"ltr\">You don’t have a soul, … -
How to directly access Webcam snapshot in django form ImageField upload?

How do i use session authentication in a two-project Django application?
I have a separate front & backend on the same domain, both in Django, for a user portal-style app. The front end has no database access. in my backend, I've set up a custom auth backend, using Django's session authentication, which works fine for logging in. but when trying to access request.user of a subsequent call from the frontend, request.user is an AnonymousUser. I'm guessing this is because the front end doesn't know about the current user, as it' done in the backend, so it's not included in the request. How do i get session authentication to work, when there are two projects? Do i need some middleware to set request.user every time? Or store the session data as cookies instead of in the db? -
CheckboxSelectMultiple in crispy forms, custom data attribute
I want to override the CheckboxSelectMultiple so I can give data- attributes to the form using the logic below: class MySelect(forms.Select): def create_option(self, name, value, label, selected, index, subindex=None, attrs=None): option = super(forms.Select, self).create_option(name, value, label, selected, index, subindex, attrs) if value: for k,attr in self.attrs.items(): # if it has a data attr in it if k[:4] == 'data': #instantiate a new object and add the data attr to the option current_object = self.choices.queryset.model.objects.get(pk=value) option['attrs'].update({ k: getattr(current_object, attr) }) return option This works just fine for non-crispy forms but since crispy never call this method, it won'w work this way. I want to override the CheckboxSelectMultiple create_option method. What is an elegant way to solve this issue without having to override the whole form field rendering process? I tried to use a custom html but it is so complicated (for my skills) to get a decent working CheckboxSelectMultiple with the checked attribute. -

What is the difference between a JsonResponse and a HTTPResponse?
I am following a tutorial and the guy used these two lines of code. I am trying to understand the difference between a JsonResponse and a HttpResponse. Both the JsonResponse and the HttpResponse leads to the user getting a pop up message ($.alert({). When the output in both cases is an $.alert({, I am slightly confused why you need a JsonResponse in one instance and a HttpResponse in another. if request.is_ajax(): return JsonResponse({"message": "Thank you for your submission"}) if request.is_ajax(): return HttpResponse(errors, status=400, content_type='application/json') views.py if contact_form.is_valid(): print(contact_form.cleaned_data) if request.is_ajax(): return JsonResponse({"message": "Thank you for your submission"}) if contact_form.errors: print("there are errors") errors = contact_form.errors.as_json() if request.is_ajax(): return HttpResponse(errors, status=400, content_type='application/json') ecommerce.js displaySubmitting(contactFormSubmitBtn, "", true) $.ajax({ method: contactFormMethod, url: contactFormEndpoint, data: contactFormData, success: function(data){ contactForm[0].reset() $.alert({ title: "Success!", content: data.message, theme: "modern", }) setTimeout(function(){ displaySubmitting(contactFormSubmitBtn, contactFormSubmitBtnTxt, false) }, 500) }, error: function(error){ console.log(error.responseJSON) var jsonData = error.responseJSON var msg = "" $.each(jsonData, function(key, value){ // key, value array index / object msg += key + ": " + value[0].message + "<br/>" }) $.alert({ title: "Oops!", content: msg, theme: "modern", }) Here is the contact form Here is the contact form when you have entered the correct data Here is the … -
Django media files and user uploaded content in production
This question was evidently asked and answered many times. Unfortunately, most answers are either old (not applicable for Django 3), or not very explicit. I understand it is not recommended to serve media files and user uploaded content (such as photos or videos) with Django, and it is recommended to use a separate server. My question is, how exactly do I do that? Do I serve the files directly with apache / nginx in the same environment (is it safe and secure to do so?)? How do I point to it in a template (say, display a user avatar in a profile page)? Do I need a cloud storage or a different server entirely? How do I point Django to it then? I couldn't find any answers or documentation addressing this questions. What I found either refers to static files, or is presented as "development only") -
I set permission_required as "is_staff" and I got error 403 permission denied
I developped a webapp with Django and I want to protect a class view with permission. It should be only authorized for admin so I added this : permission_required = 'is_staff' But when I try to access to the view with my admin profiles (and I set their status as staff) I got this error : 403 Forbidden, permission denied. The fact is that if I try with super user profile it works. So I don't understand why 'is_staff' is recognized as 'is_superuser' Thank's for reading -
How can I cycle through dictionary on click in Django?
I'm building a simple flashcards web app. I've filtered my flashcards according to the deck and passed them to the deck template. I'm looking for a way to cycle through these cards on click.

Combining two models in one form?
I am creating an Invoice App. I would like to be able to add some item to an invoice. To achieve this, the app got two models: Invoice and InvoiceItem. I have combined the two models into one form. What I am trying to achieve now is to able able to add some item in the table of the invoiceform. At this moment, I can only add one item.

Setting a form field to the object id in Django's DetailView
Let me explain my problem using some code: I am writing a simple blog application. I have a Post ListView, which lists the blog posts (obviously), and a DetailView which shows the content of the selected post. The DetailView uses the default keyword object to reference the post instance shown in the DetailView. There is a comment section at the end of each blog post. In forms.py I have a CommentForm class: class CommentForm(ModelForm): class Meta: model = Comment fields = ['author_nickname', 'content'] And in models.py I have a Comment model: class Comment(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) author_nickname = models.CharField(max_length=10) date_posted = models.DateTimeField(auto_now_add= True) content = models.TextField(max_length=90) post = models.ForeignKey(Post,on_delete=models.CASCADE) I use a DetailView to show the content of the selected post, but since it also has a form for adding comments to the comment section, it inherits from DetailView and FormView, like so: class PostDetailView(DetailView, FormView): model = Post form_class = CommentForm success_url = '/thanks/' def form_valid(self, form): form.save() return super().form_valid(form) Now, here is the rub: I want the CommentForm to add a comment to the post that is shown by the DetailView, where the form is (obviously).

Django - url scheme for nested relationship
I have 3 models: Student, Macro and LTO. Student and Macro have a ManyToMany relationship though table MacroAssignement, and LTO has a OneToOne relationship with MaroAssignement. I need to fetch from the api each LTOs related to the same MacroAssignement (so, each LTOs of a given Macro related to a given Student). The http GET method would use a url like so 'http:localhost:8000/myapp/students/student_id/macro/macro_id/lto/lto_id' ( for example 'http:localhost:8000/myapp/students/1/macro/2/lto/3'. I'm struggling with the url configuration. Here's my current urls.py macro_router = routers.DefaultRouter() macro_router.register(r'macro/(?P<pk2>[0-9]+)/lto/', LTOViewSet) router = routers.DefaultRouter() router.register(r'users', UserViewSet, basename='user') router.register(r'students', StudentViewSet) router.register(r'macro', MacroViewSet, basename='macro') urlpatterns = [ re_path('^', include(router.urls)), ] To clarify, the 'macro' segment inside router, linked to MacroViewSet, is used to access Macro objects as independent entities (performing CRUD operations on it), not yet related to any Student. On the contrary, 'macro' segment in macro_router refers to a particular macro of a given Student. Basically I'm using the same approach of this previous post, but when I try to connect to the api I get the following error: django.core.exceptions.ImproperlyConfigured: "^macro/(?P<pk>[0-9]+)/lto//(?P<pk>[^/.]+)/$" is not a valid regular expression: redefinition of group name 'pk' as group 2; was group 1 at position 31 I don't know how to set up my urls
