Django GraphQL django-graphql-jwt token not working in self-signed ssl server
I'm using django-graphql-jwt for GraphQL API authentication. Deployed to ubuntu server with self-signed ssl. Here is the mutation for authentication mutation { tokenAuth(email: "example@test.com", password: "password") { token } } So I used this token for authorization. Request Header: Authorization: JWT <token> Request Body: query { me { username firstName lastName email phone } } Result: { "errors": [ { "message": "'AnonymousUser' object has no attribute 'email_verified_at'", "locations": [ { "line": 2, "column": 3 } ], "path": [ "me" ] } ], "data": { "me": null } } This is correctly working in none-secure server(http). How can I fix this issue? Regards. -
Python Django: Customize Admin Startpage as analytical Dashboard
I am currently developing a mobile app using Ionic and I am using Django Admin Interface as sort of Backend for adding and editing the content of my mobile app through a MySQL Database. I currently wish to create a custom analytical dashboard for tracking the usage of the users of my mobile app in the startpage of the Django Admin. While there are some analytical packages for tracking the usage in Django, they only function for web applications. In my case I need to gather and display aggregate data from my database (Django models & not Django models) as well for other APIs. Is there a way how can I fetch data in form of SQL queries and display them in my dashboard using Python (Django)? And how can I extend the starting page of Django Admin to a full analytical dashboard with the named functionalities? I am currently struggling with this as I am new to Django. Any help is much appreciated! -
Django. IntegrityError: NOT NULL constraint failed: MyApp_song.albums_id
For starters, I just started learning Django. I'm trying to add a new song object to my album via the form. But I don't want to manually select the album (my foreign key) that I want to add a new song to. Instead, I want the value of my foreign key to be set depending on the album I'm adding a new song from. How can i do that in Django? I tried to do it like this: views.py class SongCreate(CreateView): template_name = 'music/album_form.html' # fields = ['albums', 'file_type', 'song_title', 'audiotrack', 'is_favorite'] model = Song fields = ['file_type', 'song_title', 'audiotrack', 'is_favorite'] def form_valid(self, form): album = get_object_or_404(Album, pk=self.kwargs['pk']) form.instance.album = album return super(SongCreate, self).form_valid(form) urls.py path('music/album/<int:pk>/add', views.SongCreate.as_view(), name='song-add'), models.py class Song(models.Model): albums = models.ForeignKey(Album, on_delete=models.CASCADE) file_type = models.CharField(max_length=10) song_title = models.CharField(max_length=250) audiotrack = models.FileField(upload_to='media/') is_favorite = models.BooleanField(default=False) def get_absolute_url(self): return reverse('param', kwargs={'pk': self.albums.id}) def __str__(self): return self.song_title Link to add a new album <a href="{% url 'song-add' album.id %}">Add album</a> But for some reason it doesn't work, although I thought it should help. So i'm getting this error. Maybe you know what's the problem? Thanks, any help will be appreciated! -
How do I upgrade an old Django Google App Engine application to a Second Generation Cloud SQL Instance?
I have a Django application that I wrote 5 years ago, which has been running successfully on Google App Engine - until last month when Google upgraded to Second Generation Cloud SQL. Currently, I have a settings.py file, which includes a database definition which looks like this: DATABASES = { 'default': { 'ENGINE': 'google.appengine.ext.django.backends.rdbms', 'INSTANCE': 'my-project-name:my-db-instance', 'NAME': 'my-db-name', }, Google's upgrade guide, tells me that the connection name needs to change from 'my-project-name:my-db-instance' to 'my-project-name:my-region:my-db-instance'. That's simple enough. Changing this leads me to get the error InternalError at /login/ (0, u'Not authorized to access instance: my-project-name:my-region:my-db-instance') According to this question, I need to add the prefix '/cloudsql/' to my instance name. So, I changed this (and the ENGINE specification) to give: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'INSTANCE': '/cloudsql/my-project-name:my-region:my-db-instance', 'NAME': 'my-db-name', 'USER' : 'root', 'PASSWORD': '******************', }, I uploaded the modified file to Google (using gcloud app deploy). This time I get a completely different error screen, showing: Error: Server Error The server encountered an error and could not complete your request. Please try again in 30 seconds. When I look in the Logs, I see: ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb It was pointed out … -

Context in Django HttpResponse
I happen to pass by Django documentation for TemplateResponse. (My question is for HttpResponse) Unlike basic HttpResponse objects, TemplateResponse objects retain the details of the template and context that was provided by the view to compute the response. Here it says that response object which we get from self.client.get() which is an object of HttpResponse, does not retain the context provided by view. But when I did dir(response) I could find context there. Kindly explain me the actual meaning of documentation. -

How to post in bulk in Django-Rest-Framework with a different format

python-social-auth redirect to the user profile in Django
I am using the wonderful python-social-authpackage, and more precisely the social-auth-app-django version since my project is using the Django Framework. Once the user is registered/logged in via any social backend, I'd like to redirect the user to their own very user profile. I know I can set a static URL in my settings.pysuch as: SOCIAL_AUTH_LOGIN_REDIRECT_URL = '/logged-in/' But how can I dynamically redirect the user to their profile given that I know their username/slug? If I could set variables in the settings.py it'd be something like: SOCIAL_AUTH_LOGIN_REDIRECT_URL = '/accounts/<slug:slug>/' But of course I can't do that. Is there any way I can achieve what I want? -
NameError: name 'LoginView' is not defined

I encounter an error due to the Django version and fix it using this explanation Switch from django string_concat to format_lazy.

Celery worker permission denied
To be quite honest I do not really know what I am doing ;) Recently I installed Mayan EDMS in a chroot on my NAS. So far I got it working ... at least I can login and so forth.

inputting algorithms to edit django model data
I have a Django project where users can input stings and images similar to a blog like twitter or reddit. The data will be stored in models.py. as such: class Post(models.Model): body = models.TextField(max_length=5000, null=False, blank=False) image = models.ImageField(upload_to=upload_location, null=True, blank=True) then in forms class CreatePostForm(forms.ModelForm): class Meta: model = Post fields = ['body', 'image'] and in views: def view(request, slug): context = {} post = get_object_or_404(Post, slug=slug) context['post'] = post return render(request, 'post/post.html', context) I used Conda to write an algorithm that edits the input photos in a unique way (for example a watermark) but I'm not sure where in my Django project to try an incorporate the algorithm. Forms.py? Models.py? after the data manipulation I would want to create a second views.py so that I could have something like this: def view2(request, slug): context = {} post2 = get_object_or_404(Post2, slug=slug) context['post2'] = post2 return render(request, 'post2/post2.html', context) I was thinking I should create a form.py class roughly like the following: class EditPostForm(forms.ModelForm): class Meta: model = Post fields = ['body', 'image'] def edit(self, commit=True): post.body = self.cleaned_data['body'] post.image = self.cleaned_data['image'] #manipulate img data #output new img and then create a view.py class roughly like the following: def new_post_view(request, … -
Return ManyRelatedManager values in template
I'm new to programming so i'm sure there's an obvious simple solution to this. I have two models (in separate apps): class Order(models.Model): parts = models.ManyToManyField(Part, blank=True) class Part(models.Model): mwos = models.ManyToManyField('mtn.Order', blank=True) The problem is when i render Order in DetailView in template i can't get the queryset of associated values. If i just put {{ order.parts }} i get my_app.Part.None. And if i do this class OrderDetailView(LoginRequiredMixin, DetailView): model = Order def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['parts'] = Part.objects.filter(mwos=self.object.id) return context I get {{ parts }} rendered as empty queryset <QuerySet []>. -
