Why have we use real path for override Oscar templates

[YusufSalahAdDin]

Hi guys, i have a question:

For override templates we have two options, but both use these settings:

location = lambda x: os.path.join(os.path.dirname(os.path.realpath(__file__)), x)


'DIRS': [
    # os.path.join(BASE_DIR, 'templates'),
    location('templates'),
    OSCAR_MAIN_TEMPLATE_DIR,
],

Normally will be enough with this:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

'DIRS': [
    os.path.join(BASE_DIR, 'templates'),
    # location('templates'),
    OSCAR_MAIN_TEMPLATE_DIR,
],

And add a template folder inside app project.

I have a big organization problem with Oscar's way:

I have a three setting file.

With the Oscar's way i have this template dir:

So, because this the tempĺate isn't loaded correctly. I have put templates folder inside settings folder for they loader successfully.

Normally is enough add a folder with the apps name, in this case Oscar, and inside struct the templates like the package templates structure:

But, in this case, Oscar can not load my custom template:

Finally, i choose make template structure as Oscar's way template path ask me:
 

And works fine:

So, why handled Oscar templates in thiw way instead use default django template handlers?

Thanks guys!
