How to avoid duplicate data in Django Template
I have this piece of code : {% extends 'base.html' %} {% load static %} {% block page_title %}Manage Staff{% endblock page_title %} {% block content %} <section class="content"> <div class="container-fluid"> <div class="row"> <div class="col-md-12"> <div class="card"> <div class="card-header"> <h3 class="card-title">Manage All Staff</h3> </div> <!-- /.card-header --> <div class="card-body"> <table id="example2" class="table table-bordered table-hover"> <thead> <tr> <th>SN</th> <th>Full Name</th> <th>Email</th> <th>Course</th> </tr> </thead> <tbody> {% for staff in allStaff %} <tr> <td>-</td> <td>{{staff.last_name}}, {{staff.first_name}}</td> <td>{{staff.email}}</td> <td>{{staff.course.name}}</td> </tr> {% endfor %} </tbody> </table> </div> </div> </div> </div> </div> </section> {% endblock content %} The block page_title is used to display the current page in base.html.

What I earlier tried was passing the value from my views.py file, so I wanna be sure I am doing the right thing -
Trying to add CSRF Token to HTML code generated in Javascript and it is not working
I am building a website using Django and React and here is my issue I want to add {% csrf_token %} to an HTML form that is produced in Javascript and it does not display when I try to add it to this: function formatPostElement(post){ var formattedPost = "<div class = 'col-12 col-md-10 mx-auto border rounded py-3 mb-4' id = 'post-" + post.id +"'><p>" + post.content + "</p><div class = 'row mb-4'><div class = 'col-md-4 mx-auto col-10'><form class = 'form' id = 'post-comment-create-form' method = 'POST' action = '/create-post-comment/" + post.id +"'><div id='post-create-form-error' class='d-none alert alert-danger'></div><input type = 'hidden' value = '/' name = 'next'/><textarea class = 'form-control' name = 'content' placeholder='Enter your comment...' required></textarea><button type = 'submit' class = 'btn btn-danger'>Comment</button></form></div></div></div>" return formattedPost } In the code above I try to add {% csrf_token %} after the form tag and before the div tag. I have another form in the same file (index.html) that has a csrf token, however that form is declared outside of javascript. What can I do to have a CSRF token running in this form? -

Nginx redirect to Sphinx docs for Django app in Docker
I've added Sphinx documentation to a Django project, and want to serve the generated Sphinx pages from the /docs uri, but I can't seem to get my uris and directories aligned to serve the right stuff. I've tried a number of configurations. Current one is included below. Django site serves OK (though not set up static file stuff yet - figure I'd have the same issues there!). But /docs returns a 404 from nginx. I've tried root vs. alias and different path settings. I've verified the volume is loaded OK on /docs so that index.html exists there, but no joy. All suggestions welcome! docker-compose.yml version: '3.8' services: nginx: image: nginx ports: - 443:443 - 80:80 volumes: - ./config/nginx:/etc/nginx/conf.d - ./static:/static - ./src/docs/build/html:/docs depends_on: - web web: container_name: inventory build: context: . dockerfile: Dockerfile.dev env_file: .env volumes: - ./src:/inventory - ./config/nginx/certs:/etc/certs expose: - 443 environment: - DJANGO_SETTINGS_MODULE=${DJANGO_SETTINGS_MODULE} command: > <Does stuff & runs gunicorn> nginx.conf upstream web { ip_hash; server web:443; } # Redirect all HTTP requests to HTTPS server { listen 80; server_name localhost; return 301 https://$server_name$request_uri; } server { listen 443 ssl; server_name localhost; # Serve up the Sphinx docs directly location /docs { # root /docs; try_files $uri … -

Django AWS S3 Image error 400 "Bad Request"

Is it possible to use When/Case in Django with `output_field` list (or array)?

Update/merge data instead of replacing it with PUT method in Django Rest Framework
In a Django app (that uses DRF), I have a user profile model. To update the profile info, I want to use PUT. However, I have a field called "meta", that is an object/dict itself. If I am missing any of its properties (gender, mobile, birthday), I will lose that data since the whole "meta" is replaced with the new one. That does not happen with any of the fields (e.g., if I do not specify the first name, the field will just stay the same). Here's an example of a PUT request body: { "id": 1, "first_name": "Jane", "last_name": "Doe", "email": "jane@example.com", "meta": { "gender": "female", "mobile": 123456789, "birthday":"01-01-1970" } } What can I do to assure that the missing properties are not lost? Is there a way to implement or force a merge/update of the previous data with the one in the request? Here's the method: def put(self, request, pk): user = User.objects.get(id=pk) serializer = UserSerializer(user, data=request.data, context={'request': request}) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) And here's the serializer: class UserSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = [ 'id', 'url', 'first_name', 'last_name', 'email', 'meta' ] -

My CSS does not appear when I use "extend" and "block" in Django

What do I have and tried: In settings.py I have included: django.contrib.staticfiles, `STATIC_URL = '/static/' In layout.html: {% load static %}, <link href="{% static 'auctions/styles.css' %}" rel="stylesheet"> The static files folders are orginized the following: MY_APP/static/auctions/styles.css And extending the layout and filling the body block, I have tried adding {% load static %} on top; I have put <link href="{% static 'auctions/styles.css' %}" rel="stylesheet"> afterwards and restarted the server, yet all this to no avail; -
Creating web card game for 4 players
I would like to make a web card game. Game should be for 4 players and it should wait for all players to connect and then start the game. Each player should see only his hand (not others hand), but all of them should see the same stack in the middle. My idea is that each player (when is on move) clicks on some card and that card will come to the middle where others will see it. There is specific order of players who is on a move. I would like to write this game in python and then use some JavaScript probably. I want to ask you what do you think is the easiest way to write this web app. I am struggling with the idea where should I write game's engine. Friend of mine has suggested me to use Django but I don't think this will solve my problem. As you probably noticed I am not very experienced in this stuff and that's why I am asking for an advice. Could you please give me an short advice how this all should be connected together and how should I continue? Thank you for your answers. -

Live video stream problems with Django
I'm trying to stream live feed from my webcam into django. My code is very very similar to the code on this github page https://github.com/log0/video_streaming_with_flask_example (just using a StreamingHttpResponse instead of a response). I only added some keystroke features with pynput to control a cursor on the stream. The problem is my mac starts getting really slow after about 30-40 seconds or so to the point where I have to restart it. My main plan is to later transfer this system into a raspberry pi web server but my worry is that if it makes my mac freeze, whats its gonna do to the Pi? A solution I thought of was to maybe pause the stream or stop it but every time I try calling the VideoCamera.del() method the whole localhost server closes instead of the just the stream stopping. Some people were saying that it may be a memory problem but I mainly code in Python and I dont have much knowledge in terms of memory so if someone can help me out with that it would be great. I'm not sure if this is a problem with my computer or wifi or what. The raspberry pi is pretty … -

Using two submit buttons to save django inlineformset as draft
I have an inlineformset that works. I have attempted to add a second submit button, that when clicked will check that a particular field in each inline form has been filled out i.e. this field becomes a required filed only when the second submit button is clicked. The problem is that when I click this second submit button the validation errors don't appear and the form just seems to submit anyway. I think the issue is within my view, within form_valid. I'm not sure what I need to return when if form.is_valid() fails. I'm teaching myself to code, so any help or direction is much appreciated.
