[1.8] MultiHost with template dir per Host

[Neyoui]

Hi,

I had create a middleware, that is able to change the template directory per host on the fly.

But it stopped working since I upgraed to Django 1.8 and I tried to fix it.

My problem is:

If I visit domain1.tld, all works fine. Django loads the templates from the right directory. (/path/domain1.tld/templates/)

But if I visit now domain2.tld, Django tried to load the template from the domain1.tld directory /path/domain1.tld/templates/ and not from /path/domain2.tld/templates/.

The debug messages shows me, that the middleware overrides the template path successfully.

Maybe someone can help me to fix it.

Details:

Django version: 1.8b1

Python: 3.4

Hi,

You might need to modify the template engine directly.
