Django not loading static files if DEBUG= False

Django dont allow loading static files when debug is False

Then what is the solution?

With debug turned off Django won't handle static files for you any more - your production web server (Apache o r something) should take care of that

Then what is the solution?

Use whitenoise It will help you serve static files from static root in production mode

Can anyone suggest some free hosting for my django website?

You can try Heroku and Pythonanywhere for hosting

Will my database persist on Heroku? I'm using sqlite3 as a database

No. U need to use postgres

Hello everyone. I have a question regarding user photos in Django production. There is a way to serve it using Nginx, but then there is a security problem. One can easily change a link a get others' photos. Seems like it is better to server images through Django. So, I configured Nginx to proxy "/user_images" requests to Django, but it does not work at all. Django is able to handle images only when debug mode is on. Can anyone give a hint or a link to a good tutorial?

Hey any project suggestions for django learning !

You can check this out https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-subrequest-authentication/

I am afraid that with Django you cannot serve user uploaded content. Method “serve” which you can use is meant only for development, not for production. You should use Amazon S3 or something similar for user uploaded content (and use signed urls for security)

Thank you!

hello, I have the following the condition on my template: {% if request.user.id in Hasliked %} <button id="likeBtn{{ i.id }}" class="likeClassBtn colorRed"> <i class="fas fa-heart"></i> </button> {% endif %} {% if request.user.id in Hasnotliked %} <button id="likeBtn{{ i.id }}" class="likeClassBtn"> <i class="fas fa-heart"></i> </button> {% endif %} where Hasliked and Hasnotliked are two different tuples passed as context with values [1,2] and [2] resp., but the request.user.id is 1. For some reason, Im not able to see the button in second condition, is there anything wrong with the conditions?

why is it that every tutorial i find for teaching django i just see them using bootsrap and not materialize css
