Django doesn't respond on some requests after deployment on server
I have a little bit weirdo behavior, of my Django app, after deployment on server with gunicorn. First, I add script to upstart, using runit tool (linux, of course). And saw that my server respond on request as it wants. Maybe it respond on request, maybe not. I was shocked, because the same configuration on my local machine works the same. So, I decided to remove script from upstart, and try to run it as on local machine, with the same script, that I removed from runit upstart. Result is better, it respond on 95 of ajax calls, but one is still does not works. Screen from chrome network monitoring. 10 seconds, takes SIMPLE request for stop/ url. I never saw, that server respond to client on start/ url, when app deployed on server. There are screens from my local machine, from Chrome network monitoring. I run apps on google compute engine, so I thought that server have not enough performance. But it's wrong. Changes of machine type have no influence. Then, I decided to take a look to logs and code. Before response I wrote these lines of code: log.info('Start activity for {}'.format(username)) return HttpResponse("started") And I can see … -

Django Celery Result : Django-DB ttributeError: 'DisabledBackend'
I'm currently testing Django Celery Results using Django DB as backend. I've followed the documentation here: http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html#django-celery-results-using-the-django-orm-cache-as-a-result-backend When my Django view calls the celery task, it gets properly added in the Django DB and the task gets executed by Celery worker. I can also fetch the task ID with below code: def contact(request): if request.method == 'POST': form = ContactForm(request.POST) if form.is_valid(): cd = form.cleaned_data res = mailer.delay( cd['subject'], cd['message'], cd.get('email', 'noreply@gmail.com'), ['seb.pouplin@gmail.com']) cel_taskid = res.task_id result = AsyncResult(cel_taskid) print(result.state) return HttpResponse(cel_taskid) However, whenever I try to fetch task status, state or ready() flag, I'm getting following exception: AttributeError: 'DisabledBackend' object has no attribute '_get_task_meta_for' Is there any limitation using Django-DB to get the task details or any other way to retrieve them ?

CSRF token gets passed in the header when performing POST
I'm setting up VueJS SPA on top of Django. I have Graphene endpoint running on /api and queries in graphiql run fine. I have set up frontend and I'm using Apollo Client to query server. There goes my setup: const CSRFtoken = Cookies.get('csrftoken') const networkInterface = createNetworkInterface({ uri: '/api', transportBatching: true }) networkInterface.use([{ applyMiddleware (req, next) { if (!req.options.headers) { req.options.headers = {} // Create the header object if needed. } req.options.headers['X-CSRFToken'] = CSRFtoken console.log('applied middleware') next() } }]) const apolloClient = new ApolloClient({ networkInterface, connectToDevTools: true }) Vue.use(VueApollo) const apolloProvider = new VueApollo({ defaultClient: apolloClient }) new Vue({ el: '#app', apolloProvider, render: h => h(App) }); My POST requests have the 'X-CSRFToken' header with value provided by Cookies. Screenshot below: I have searched through the web but can't find anything related. Thanks in advance! -

Correctly loading Keras model in Django that supports multi-tenancy
I am try to write a REST api in django that uses a Keras model to return a prediction. However the load_model() function takes some time to load the model and I don't want my users to have to wait so long (each time the model is initialized). What would be the correct way to initialize the model so that is is loaded once and the predictions are done using that same model? On a side note one method that I thought cold be possible was to initialize the model in settings.py as below : settings.py json_file=open("model.json","r") loaded_json=json_file.read() json_file.close() model=model_from_json(loaded_json) model.load_weights("model.h5") MODEL=model And then in my views.py I use this variable MODEL as : views.py from django.conf import settings model=settings.MODEL def index(): print "Predicting" res=model.predict(numpy.stack([test_img])) print res This works great if only one user is active at a time ( model is initialized once and all subsequent predictions are done using that model). However if multiple users are active at a time then it works good for the call that came first but the latter call gives the error 'NoneType' object has no attribute 'shape' Apply node that caused the error: ConvOp{('imshp', (31, 31, 32)),('kshp', (3, 3)),('nkern', 64),('bsize', None),('dx', 1),('dy', … -
URL passes parameter in my Django project
I am just a beginner of Django, these days I followed a mooc to learn Django, I wanted to set up my first website, but something went wrong and I can not figure out. I wanted to write a regex with parameter 'cate' in URLS.py to match the video function in my view.py, judging whether 'cate' eequals 'editors', if yes it will bring back data with attribute "editors_choice". However, I found no it never changes, so I printed 'cate' in view.py and found it always None and I still don't know why. Following is my code: def video(request, cate=None): print(cate) context = {} = if cate is None: video_list = Video.objects.all() if cate == 'editors': video_list = Video.objects.filter(editors_choices=True) else: video_list = Video.objects.all() page_robot = Paginator(video_list, 16) page_num = request.GET.get('page') try: video_list = page_robot.page(page_num) except EmptyPage: video_list = page_robot.page(page_robot.num_pages) # raise HTTP404("Empty") except PageNotAnInteger: video_list = page_robot.page(1) context['video_list'] = video_list return render(request, 'ten_movie.html', context) -
Validation error with django formsets (blank fields not accepted)
I have two models (Workout and ExerciseSet) that are connected in a One to Many relationship. I'm trying to use a CreateView to build a form that allows me to create a workout and exercise set(s) at the same time. The thing is when I only have one exercise set field (extra=1 in the inlineformset_factory), it works - but when I want to set extra to a larger number like 3, it will only work if all the workouts are set up. Otherwise it throws a null value in column "repetitions" violates not-null constraint error. I'm thinking of overwriting the clean method in the inlineformset class to solve this, but when I call super.clean(), it keeps returning None. Just wondering if anyone could help. models.py class Workout(models.Model): profile = models.ForeignKey( 'Profile', on_delete=models.CASCADE, blank=False ) class ExerciseSet(models.Model): EXERCISE_TYPE_CHOICES = ( ('pushup', 'Push Up'), ('situp', 'Sit-up') ) workout = models.ForeignKey( 'Workout', on_delete=models.CASCADE, related_name='exercise_sets' ) repetitions = models.PositiveIntegerField() exercise_type = models.CharField(max_length=100, choices=EXERCISE_TYPE_CHOICES) forms.py class WorkoutForm(ModelForm): class Meta: model = Workout exclude = () class ExerciseSetForm(ModelForm): class Meta: model = ExerciseSet exclude = () class CustomExerciseSetInlineFormSet(BaseInlineFormSet): def clean(self): cleaned_data = super().clean() print('custom') print(cleaned_data) ExerciseSetFormSet = inlineformset_factory(Workout, ExerciseSet, form=ExerciseSetForm, formset=CustomExerciseSetInlineFormSet, extra=3) views.py class WorkoutCreate(CreateView): model … -
Django Rest Framework: Register User model to Course model
I have a Django REST API that has a User and Course model defined as: class User(AbstractBaseUser): id = models.UUIDField(primary_key = True, default=uuid.uuid4) username = models.CharField(blank=False, max_length=32, unique=True) notes = models.ForeignKey('notes.Note', null=True, related_name='notes') courses = models.ManyToManyField(Course, related_name='courses') class Course(models.Model): course_name = models.CharFIeld(max_length=64) course_tutor = models.ForeignKey('authentication.User', related_name='tutor', blank=True) course_students = models.ManyToManyField('authentication.User', editable=True, related_name='students') My serializers are defined like this class UserSerializer(serializers.ModelSerializer): notes = serializers.SerializerMethodField('get_notes_for_user') courses = serializers.SerializerMethodField('get_courses_for_student') def get_courses_for_student(self, obj): # What do I do here?? def get_notes_for_user(self, obj): queryset = Note.objects.all().filter(note_owner=obj) return queryset.values() class Meta: model = User fields = ('id', 'username', 'notes', 'courses') class CourseSerializer(serializers.HyperlinkedModelSerializer): course_students = serializers.HyperlinkedRelatedField(view_name='user-detail', lookup_field='pk', many=True, read_only=True) class Meta: model = Course fields = ('course_name', 'course_tutor', 'course_students', ) My question is: How do I correctly (and RESTful) register users to courses? I have thought of an intermediate model such as Subscriptions but I do not know the correct approach. The endgoal is to have an User/Course/Activity API that allows certain Users to "subscribe" (Hence the intermediate Subscription model) to a certain course/activity. I'm troubling myself over how to implement this and would appriciate additional insights. If I have failed to provide enough details to resolve this please do tell. I will gladly supply any additional … -

Redirect and a different html page being called, but same url
I'm working through various Django tutorials in order to get an LDAP Backend up and running. I have a simple login page using a user's credentials, and an extra field to insert a user to be searched for. When hitting the submit button on my page, I get redirected to the correct html, but the url remains the same. I'm not sure that this could pose any problems, but if not, does it really matter if a different page has the same url? How should I be calling the redirected page? urls.py urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^$', ldap_authentication, name='index'), url(r'^logout/$', logout_view, name='logout'), url(r'^search_page/$', ldap_authentication, name="search_page") ] views.py def ldap_authentication(request): if request.POST: username = request.POST['username'] password = request.POST['password'] searchFilter = request.POST['searchUser'] domain_and_login = '{}\\{}'.format(DOMAIN_NAME, username) ''' Connection to LDAP... ''' split_dn = [domain_and_login, "ou=Konzern", "dc=abcdef", "dc=de"] return render(request, 'search_page.html', {'dn':split_dn}) return render(request, 'login.html') If I do a redirect, then I understand that Django looks this up in the urls.py, however the search_page.html doesn't have any view in the views.py.
