[Django]-How do I call templates with same names at different directories in Django?

With your current directory structure, you can’t – it’s done this way to allow you to override templates by apps later on in your INSTALLED_APPS setting. The convention is to use a directory structure more like:

app1/templates/app1/base.html
app2/templates/app2/base.html

And then use app1/base.html or app2/base.html to refer to the one you want.

Edit

To be more clear on what I mean: your project structure could look like this:

mysite
    - templates
        - base.html
    - manage.py (etc...)
    - app
        - models.py (etc...)
        - templates
            - app
                - base.html

Then you can use base.html to get the first one and app/base.html to get the other – and the relevant app templates are all packaged inside the app they refer to, but are namespaced.
