Displaying image django rest framework
I am trying to get image url from database by sending id in the request. views.py class RenderImage(APIView): def post(self, request): print(request.data) serializer = ImageSerializer(data = request.data) print(serializer.is_valid()) print(request.data['id']) if(serializer.is_valid()): print("1") tags = serializer.data['id'] output = {} images = Image.objects.get(pk = request.data['id']) print("2") # output['image'] = serializer.data for image in images: output.append(image.url) text = {'status': 1, 'data':output} else: text = {'status':-1, 'data':serializer.errors} return Response(text) models.py class Image(models.Model): image = models.ImageField(upload_to = 'images/') def __unicode__(self): return os.path.basename(self.image.name) serializers.py class ImageSerializer(serializers.ModelSerializer):#test class Meta: model = Image in the views the serializer is invalid so the view doesn't proceed any idea whats wrong?? -

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
I know this question has been asked before, but I haven't found an answer that solves my situation. I'm looking at the Django tutorial, and I've set up the first URLs exactly as the tutorial has it, word for word, but when I go to http://http://localhost:8000/polls/, it gives me this error: Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: ^polls/ ^% [name='index'] ^admin/ The current URL, polls/, didn't match any of these. I'm using Django 1.10.5 and Python 2.7. Here is the code I have in relevant url and view files: In mysite/polls/views.py: from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("Hello, world. You're at the polls index.") In mysite/polls/urls.py: from django.conf.urls import url from . import views urlpatterns = [ url(r'^%', views.index, name='index'), ] In mysite/mysite/urls.py: from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^polls/', include('polls.urls')), url(r'^admin/', admin.site.urls), ] What's going on? Why am I getting 404s? -

Angular request to Django REST API is taking too long
I've a request to my REST Api that only takes 0:00:00.000129 to process in the back end. class GetRequest(APIView): def get(self, request, format='json'): time = timezone.now() serializer = ObjSerializer(Obj.objects.all(), many=True) print (timezone.now()-time) return Response(serializer.data, status=status.HTTP_200_OK) But Angular takes 3.2 minutes to finish the following request: MainService.getAllObj = function() { return $http.get(frontendUrl + "obj/?format=json"); }; I'm calling the service function in a controller: $scope.loading = true; MainService.getAllObj().success(function (objs) { $scope.objs = objs; $scope.loading = false; }); How can I reduce the angular processing time?

Django allauth bug: deployment from localhost to herokuapp
I'm using allauth in my Django app for basic sign-in, sign-up, password reset functionality, etc. There are no social media apps attached. Everything is working fine on localhost. When I deploy to herokuapp, I change my site in the admin page to my herokuapp domain, keeping the site id the same in my code. However, users that sign up keep getting magically deleted, and users that I used in testing and deleted keep magically returning. When I check what the site domain is in the admin page, it says "localhost" again. I've tried switching it a couple times now, but it keeps doing this. There is no error message, but I thought I'd post this problem in the off-chance that someone has encountered it. -
bootstrap-select doesn't work for Django template
I am building a Django project and try to use bootstrap-select plugin, I followed the tutorial to import needed libraries but nothing display in the browser, it is empty.

Does Wagtail template variable "self" exist in (Django) pages that don't subclass Page?
Wagtail newbie here templating a response that is derived from a Django-based models.Model class and am noticing that it does have the {{ page }} template variable available but not the {{ self }} one. Just looking for confirmation that the this is because {{ self }} template variable is only available to classes that extend Page. Not finding anything in the docs about it. Thanks in advance, John -

How do I make a form field read only or otherwise non editable in a django generic FormView?
I have a form that pre-populates the user field on page load with the currently logged in user. I would like to grey this field out so that the user can't change it to a user who isn't logged in. I would like for the user to be able to change the rest of the fields. I've tried using the init function on the model form and the view to no avail. Any pointers would be appreciated. forms.py: class PtoRequestForm(forms.ModelForm): class Meta: # Model to be used in the form. model = PtoHistory # Define which model fields to include in the form. fields = [ 'user', 'start', 'end', 'leave_type', ] # Attach input widgets to fields for a friendlier user interface. widgets = { 'start': DateTimeWidget(attrs={'id':'start'}, usel10n = True, bootstrap_version=3), 'end': DateTimeWidget(attrs={'id':'end'}, usel10n = True, bootstrap_version=3), } views.py: class IndexView(FormView): template_name = 'accounts/index.html' form_class = PtoRequestForm success_url = '/accounts' # Pre-populates the form with the specified values on page load. def get_initial(self): return {'user': self.request.user} # Function runs when form is submitted.

Django csrf fails after logout login new user
Even if I understand the problem, I'm not sure how to solve this. I have a django powered api that has an endpoint that lets the user change the email. If the logged user A enters a already existing email, it checks if the logged user A entered a password that corresponds to the already existing user B object (i.e he owns another, older account). If that is the case, I have to logout the actual user A and login again the already existing B account. ... if User.objects.filter(email=email).exists(): # If the email already belongs to another account user = authenticate(username=email, password=password) if user is not None: # The user is the owner of the existing account, he has the password # Get already existing client object client_existing_user_obj = Client.objects.get(user=user) # get clients actual cart actual_cart = client.cart # update existing clients cart with newly created cart client_existing_user_obj.cart = actual_cart # logout user with the old email, login already existing user logout(request) login(request, user) ... The endpoint works correctly, it returns 200. However, the next post & put requests answer 403 - "detail": "CSRF Failed: CSRF token missing or incorrect." How can I solve this? Any advice will help. -
Any alternatives for OneToMany or ManyToOne in Django
I have a NOTIFICATION and an USER app in Django. The code goes something like : class Notification(models.Model): user = models.ForeignKey(User , related_name = "notification" .... .... and class User(models.Model): notifications = models.OneToManyField(Notification , related_name = "user" .... .... Now I know that models.OneToManyField doesn't exist in Django. I get the fact that I can simply access the user from the notification instance of the model. But I suppose that would somehow slow my system because in production I would keep all the instances of Notification Model. For example : I'm expecting around 500+ notifications per user once the system is in production for a significant amount of time. I suppose, it would just be easier to access all the notifications of one user directly rather than sifting through the whole Notification Table to find notifications of a specific user. I've read this and the documentation to an extent and I'm not able to find a solution to my problem. Also I'm not sure about the processing constraints of a processor to obtain all the Notifications from the whole Notification Table. I'm just assuming that it'll be somewhat slower. -

Why can't I make my own test database for my django project?
I am currently deciding what testing packages to use with my django project, specifically how to populate data before I run tests. I have looked into: Fixtures: Many people seem to be against this since modifying JSON can be difficult and hard to maintain. Factory boy: My project has a lot of hierarchy to it, so I feel like creating an object from a model that is really low in the hierarchy is really slow. The idea I have in my mind is to just make a database that I will always run tests against. Since I know what data is in it, shouldn't it work similarly to fixtures without the hassle of JSON? Since I haven't seen this idea through my research, I assume this is a bad idea. Why is it a bad idea though? -
