Django 'block' tag with name 'content' appears more than once

Question

I got this error when making an app and I think the problem is located in my login.html as it points in the error sheet. Is it because I have 2 {% block content %} which it conflicts? Thank you for helping me

I also got a traceback linking to my views.py

Answer 1

Yes, the error is quite clear: you have two blocks named "content".

To be honest I can't understand what you're doing, as the second block seems to be an exact duplicate of the first. You can't have two extends tags either.

Answer 2

You can do the things you want to in the back-end, ie:- Python. You can for example do something like:-

# views.py::
if something is True(any condition for that matter)
msg = "something"

else:
msg = "Something else"

# template, it is here -- index.html::
{% block title %}{{msg}}{% endblock title %}
