Django cache and page part that depends on login
Suppose I have some page at example.com/page If a user is not logged in, then I show Log in button. If the user is logged in, then I show menu. The problem is that it doesn't work with cache. If I render page and save it in cache, then it is always with login button. How to avoid this? -
Extending User model when users haven't created accounts yet
I am building a system for a startup where customers can book small home repair services with the service providers. Everything so far was done manually by a human, using a large spreadsheet that stores contact information of the service providers, like name, e-mail, location, phone, etc. As the customers reach the company's website asking for repairs, a person go though the spreadsheet, looking for a suitable service provider, contact the provider and checks availability and books a time/date that works for both provider and customer. The idea now is to automate this process, sending sms and whatsapp messages to both parties, instead of a person having to deal with this process, by using Trello. The startup owners want to avoid the trouble of having to ask for all service providers to create accounts for now, but I think it's a good idea to extend the Django's User model, as later on it would be easy to transition to a system where the providers has their own accounts with username and password, and easily connect with all the services that have been done. But right now I can't use the User model, as I don't have any accounts yet. Should … -

Django Like Syste --> RedirectView not redirecting to post
I ran into a problem while trying to figure out how to implement a liking system for my Django blog. I have a post Detail View and a PostRedirectView. I want the redirect view to get the absolute URL for the Post I look at and toggle a like/unlike as my liking system is a ManyToManyField linked in my models.py for the post.

The code of an HTML dropdown button seems fine, but it doesn't work [closed]
I am following a book to learn Django. One of the dropdown buttons is not working, the code is the same as the one provided by the book. I tried to find reason on my own, but it heavily involves bootstrap or something. Anyone can take a look at the snippet below. <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> <a class="navbar-brand" href="{% url 'home' %}">Newspaper</a> {% if user.is_authenticated %} <ul class="navbar-nav mr-auto"> <li class="nav-item"><a href="{% url 'article_new' %}">+ New</a></li> </ul> {% endif %} <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarSupportedContent"> {% if user.is_authenticated %} <ul class="navbar-nav ml-auto"> <li class="nav-item"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> {{ user.username }} </a> <div class="dropdown-menu dropdown-menu-lg-right" aria-labelledby="navbarDropdown"> <a class="dropdown-item" href="{% url 'password_change'%}">Change password</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="{% url 'logout' %}"> Log Out</a> </div> </li> </ul> {% else %} <form class="form-inline ml-auto"> <a href="{% url 'login' %}" class="btn btn-outline-secondary"> Log In</a> <a href="{% url 'signup' %}" class="btn btn-primary ml-2"> Sign up</a> </form> {% endif %} </div> </nav> -

How to change the redirect_uri in moziila_django_oidc?
I want to integrate Keycloak into a Django project and I am using mozilla_django_oidc to do so. The problem I have is that when I send a request to the authorization endpoint of keycloak the redirect_uri is being set as: redirect_uri=http%3A%2F%2Fdjango%3A8000%2Foidc%2Fcallback%2F, but instead of django there should be the IP of my application. I don't know why it uses django as the domain name. My configuration in the settings.py looks like this: OIDC_RP_CLIENT_ID = os.environ['OIDC_RP_CLIENT_ID'] OIDC_RP_CLIENT_SECRET = os.environ['OIDC_RP_CLIENT_SECRET'] OIDC_OP_AUTHORIZATION_ENDPOINT = 'http://172.20.159.83:8080/auth/realms/Test/protocol/openid-connect/auth' OIDC_OP_TOKEN_ENDPOINT = 'http://172.20.159.83:8080/auth/realms/Test/protocol/openid-connect/token' OIDC_OP_USER_ENDPOINT = 'http://172.20.159.83:8080/auth/realms/Test/protocol/openid-connect/userinfo' OIDC_OP_JWKS_ENDPOINT = 'http://172.20.159.83:8080/auth/realms/Test/protocol/openid-connect/certs' LOGIN_REDIRECT_URL = 'http://172.20.159.83/test' LOGOUT_REDIRECT_URL = 'http://172.20.159.83/' And in the urls.py it is: path('oidc/', include('mozilla_django_oidc.urls')), The request to the authorization endpoint with all parameters: http://172.20.159.83:8080/auth/realms/Test/protocol/openid-connect/auth?response_type=code&scope=openid+email&client_id=MyApplication&redirect_uri=http%3A%2F%2Fdjango%3A8000%2Foidc%2Fcallback%2F&state=3YxLAg8kX1bC1yTDMqKh8L05bIP5z9cB&nonce=jZ6KEZhk9tWOwdXRSqTUoF8lzg7aLU70 So, as the title says, how can I change the django part of the redirect uri to point to the IP of my application? How is this parameter being set? -

Photos removed from the disk continue to appear on the website
I'm developing a website for my student project. I use Django and Docker for containers.

Why is my .css file not fully rendering on server, but working locally?
Essentially, my style.css file is only partially rendering on the live server, despite working properly in my local development environment. Prior to this update I just pushed, things were working fine - I changed some content in the .css file, but not the content that is being affected by this issue. The parts of the CSS file that seem to be affected: table.student { width: 75%; border: 3px inset; margin-left: auto; margin-right: auto; } table.admin { width: 50%; border: 3px inset; margin-left: auto; margin-right: auto; } h1{ font-family: Segoe, "Segoe UI", "DejaVu Sans", "Trebuchet MS", Verdana, sans-serif; font-size: 30px; padding: 1%; text-align: center; } The rest of the .css file is being applied just fine. I didn't change the file location (myapp/static/css/style.css), or how/where the file is called (in my base.html file with the line <link rel="stylesheet" href="{% static 'css/style.css' %}">). I have run collectstatic with no discernible effect. The python version I am using is 3.7.2 -

Querying from AJAX in Django (GET)
I have a template (menu.html), and I am making an AJAX call with JavaScript. Then, I want to process that call (throughout the GET parameters) and make a query from Django's ORM. \ My JavaScript code is: $.ajax("/showcart", { type: "GET", data: { product: product, type: product_type }, success: function(response) { console.log("SUCCES SUCCESS SUCCESS") console.log(response); }, error: function(resp) { console.log("ERROR ERROR ERROR!") console.log(resp) } }) product is the name of my product, and product_type is the size of my product. Then, in my views.py, I handle this call with: def showcart(request): product = request.GET['product'] if request.GET['type'] == "small": size = f"{request.GET['type']}_price" elif request.GET['type'] == "large": size = f"{request.GET['type']}_price" else: size = "price" product_name = product.split("-")[0] product_id = product.split("-")[1] return JsonResponse( { "product_name": product_name, "product_id": product_id, "size": size, "queryresult": "nothing here", } ) For example, product_name is "Sub" and I have a model in models.py called Sub. My goal is querying the price, for instance, with the product_name. But, since it is a string type, Django doesn't allow me to do that. Does anyone know how this works? Thanks, -
Is there a way to expose Django admin as a RESTful API?
I want to create, update and delete my objects using an API just like I can from an admin panel but I already have a user API and I don't want to repeat myself. Is there a library I can use to achieve what I want? I've tried django-restful-admin but it did not work properly on Django 3.1 (django.core.exceptions.AppRegistryNotReady was raised though I configured it properly). -
