Cannot load DetailView template . URL is generated incorrectly
I am a beginner in Django and I am learning CBV's. I used Django' built in User class to create several users on my website and then i created the following views below . The url generated for my user_list view is http://127.0.0.1:8000/basicapp/user_list/ and works. It shows the users The url generated my user_detail view is http://127.0.0.1:8000/basicapp/1/ (2,3...and so one) and works when manually entered. It shows the user detail The problem is this: In the user_list.html, i add : <a href="{{person.id}}"and In the url.py I add: url(r'^(?P<pk>[-\w]+)/$',views.UserDetailView.as_view(),name='detail') So, when the user list page loads with my users as links , when i hover over the links i get a path like: http://127.0.0.1:8000/basicapp/user_list/1 - this link does not work. I click on it and does not do anything I should be geting : http://127.0.0.1:8000/basicapp/1 . This link does work because i tested it manually.

Django refusing to serve NEWLY ADDED static files
The problem Django is acting weird. I built a website a month ago. I have a static/img folder in my app, with a bunch of logos and images in it. I refer to them with <img src="{% static 'img/logo-elephant.png' %}"> And it works. However, I added a new file to the very same folder, and when I refer to it, <img src="{% static 'img/white-logo.png' %}"> it gives me a 404 error. I am completely stumped. Its like newly added files are invisible to Django. Even if I copy an existing file and rename it to something, it raises a 404 error. Stuff I already tried Printing the STATIC_ROOT to make sure it's pointing to the static folder of my app. It is. Running collectstatic. Though it shouldn't make a difference, this is a development server, but I ran it just for good measure. -

How to handle nested foriegn keys in django rest
I am working on a API that has several models, each having a foreign key to its parent. I have figured out how to write the models as well as the serializers file. But I can not figure out how to work around the views file, where I can POST as well as GET data at any level. The tutorials for DRF are quite tricky with only one/two models.

Best Way To Serve Images in Django 3.0?
So I 'm working on a project in django - it's like a variation of a blog. There will be 4 mini blogs within the website and the admin for each can create new posts - so they can also add an image to their post. Now that django has recently been update (django 3.0 is here), I was wondering, what is the best way to store and serve these images in production? Could someone maybe link to a part in the documentation? I don't think this will come under staticfiles will it? I searched the documentation with keywords like "Media", "Serving images" etc but didn't really find much. -

How do I implement Google Sign in for my app which has an android frontend and a Django back end?
The backend is on Django on a server, which has all the user profile data. The front end is the android application which will run on the user's phone. I want to implement google sign in (using Google OAuth2), so that the user signs in and can now be considered by the server to be authenticated. As far as I understand, the Google OAuth2.0 flow will happen like this: 1) The user clicks on "Sign in with Google". This sends the client_id (will this be the client ID of my backend application which I registered on google dev console?) and the redirect url (will this be a url to a view on my backend app?) to the google oauth site. 2) The front-end now gets the auth_code which it sends to the backend server 3) The backend uses the client_secret, client_id, auth_code and sends it to google oauth site. 4) The backend now has the access_token, which it sends to the front-end. The front-end now has the access_token. 5) How is the front-end authenticated when it sends an API request for data to the backend? What can I use for Django and Android to implement this specifically? -
