(Nginx+Daphne+Django) Error during WebSocket handshake: Unexpected response code: 404
I have an Django(3.0) app using Daphne as an app container and Nginx as proxy server. Daphne -u /home/ubuntu/virtualenvs/src/app/app.sock app.asgi:application My problem is that the websocket connection failed. (index):16 WebSocket connection to 'ws://example.com/ws/chat/1/' failed: Error during WebSocket handshake: Unexpected response code: 404 I'm pretty sure that my app setting and route is just fine. Because if I stop Nginx, bind Daphne to 0.0.0.0:8000 and use real IP("ws://xx.xx.xx.xx:8000/ws/chat/1") as URL, the websocket connection established and very stable. How should I modify my Nginx to make websocket work? #my nginx setting upstream websocket { server unix:/home/ubuntu/virtualenvs/src/app/app.sock; } #websocket settings map $http_upgrade $connection_upgrade { default upgrade; '' close; } server { listen 80; listen [::]:80 default_server; listen 443 SSL default_server; listen [::]:443 SSL default_server; server_name example.com; return 301 https://example.com$request_uri; ssl on; # certificate settings ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; ssl_session_timeout 10m; #ssl_session cache shared:SSL:1m; #ssl_protocols TLSv1 TLSv1.1 TLSv1.2 SSLv2 SSLv3; #ssl_prefer_server_ciphers on; #ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!$ location / { root /home/ubuntu/virtualenvs/ include proxy_params; proxy_pass https://websocket; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Frame-Options SAMEORIGIN; proxy_pass_request_headers on; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } location ~* \.(js|css)$ { expires -1; } } -

Improving Admin using django-pagedown
I am currently trying to utilize django-pagedown to preview posts in admin. However, there are a few things that I would like to add that I don't know how. The two issues are that I do not know how to align the textarea correctly, and I cannot render LaTeX using MathJax in Pagedown correctly. This is what I'm talking about: So far, this is what I have done: This is my Problem Model: class Problem(models.Model): slug = models.CharField(max_length = 250, unique = True) topic = models.ForeignKey(Topic, on_delete = models.CASCADE) questionToProblem = models.TextField() solutionToProblem = models.TextField() class Meta: ordering = ('questionToProblem',) def get_url(self): return reverse('solution_details', args = [self.topic.slug, self.slug]) def __str__(self): return self.questionToProblem Like what the documentation says, I have added a separate form for Problem: class ProblemForm(forms.ModelForm): questionToProblem = forms.CharField(widget=AdminPagedownWidget()) solutionToProblem = forms.CharField(widget=AdminPagedownWidget()) class Meta: model = Problem fields = "__all__" And finally, in admin.py, I used: @admin.register(Problem) class ProblemModelAdmin(admin.ModelAdmin): form = ProblemForm fields = ('questionToProblem', 'solutionToProblem') Unfortunately, changing the variable names from questionToProblem and solutionToProblem solves this issue, but the resulting textarea is completely blank. Another issue is that how would I implement MathJax in django-pagedown so that LaTeX code can be displayed properly? Please help. -

Django unquote() with url parameters
I had used unquote in my urls before to get special characters in the url like so: path('example/<str:phone_number>', views.find_user_by_phone_number.as_view(), name='api.find_user_by_phone_number'), #call with example/+849323212231 and in my views: from urllib.parse import unquote ..... phone_number = unquote(str:phone_number) print(phone_number) and it worked greate and i got +849323212231 with special character + But now i need to make url with multiple parameters that can has phone_number in it: path('example', views.find_user_by_phone_number.as_view(), name='api.find_user_by_phone_number'), #call with example?phone_number=+849323212231 With view to handle parameter: ... phone_number = unquote(request.GET.get('phone_number')) print(phone_number) And the result from the print i got was " 849323212231" with whitespace at the start. Seems like value from request.GET.get('phone_number') return " 849323212231" so plus turned into whitespace. How do i get special character with named parameter in url ? -

python-social-auth django Linkedin : how to callback to my domain?

Using Django ContentTypes to define a dataset
I want users to define a set of content they want to work on in a Django site with (potentially) quite diverse types of content. I am using ContentTypes and the GenericForeignKey relation to be able to tag any and all content to a particular dataset. My problem is giving the user a sensible series of steps, something like this: 1. Choose which Apps hold data of interest [form] 2. Choose which Models for each App hold data of interest [form] 3. Any columns you don't care about? [form] 4. Any rows you don't care about? [form] 5. all surviving rows are now IN, and we save them as GenericForeignKey entries against the Dataset. I am a bit stuck as to how to implement this logic, because ContentTypes is already a compound, modeled by 'app_label' and 'models'. class Row_link(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') class Dataset(models.Model): setname = models.CharField(max_length=20, default="[empty]") members = models.ManyToManyField(Row_link) I could add 'app_labels', 'models', and 'columns' fields to the Dataset but they ought to be derived properties from the 'members' field once that field is fully selected. But 'app_labels', 'models' and 'columns' are only needed to guide the user through …
