I'd like to integrate Spirit with an existing project. The project has a custom user model, nothing fancy just a few extra fields really. Saw this older thread, can something similar still be done? Django version is 1.11.8
That's old, don't pay attention to it. Spirit used to have its own custom user model, but now it just extends the default model with a OneToOneField, so it's a lot easier to integrate to any project. I don't think you'll have any issues integrating it into your project, as long as your custom model has all the default django fields.
