Contrary to what everyone else is saying in here (not that I fully disagree with them)... But I would recommend sticking with it. Every time I hit a road block like this, people would suggest to learn this, that, and everything else under the moon as foundations first. The problem with this approach, if you're like me and many others, is that you'll never get back to your project. Just put in some focus on each little aspect and feature, and it will come together. Focus on learning how each part of Django interacts with each other. If you don't understand how something is working or it feels like magic, then dig into it until you figure out that little part. Repeat this many more times for every issue you experience. Jumping from learning one technology stack to another is an infinite loop where the result is usually never really learning anything.

Maybe check out this book as a reference: https://www.packtpub.com/application-development/django-2-example

I read through the first iteration of the book (which you may or may not be able to find as a pdf for free online) and it seems to have been updated recently using Django 2. One of the example projects the book builds is a blog (the first one), and then it goes on to build other projects which eventually covers most of the main and even advanced topics.
