Template-loader postmortem

Django tried loading these templates, in this order:

    Using loader django.template.loaders.filesystem.Loader:
    Using loader django.template.loaders.app_directories.Loader:
        C:\Python34\lib\site-packages\django\contrib\admin\templates\base.html (File does not exist)
        C:\Python34\lib\site-packages\django\contrib\auth\templates\base.html (File does not exist)

My settings.py file:

import os

SETTINGS_PATH = os.path.dirname(__file__)
PROJECT_PATH = os.path.join(SETTINGS_PATH, os.pardir)
PROJECT_PATH = os.path.abspath(PROJECT_PATH)

TEMPLATE_LOADERS = (

I tried to change settings.py in such way too:

changed settings.py:

)

My project structure:

views.py:

from django.views.generic import View
from django.shortcuts import render


class Index(View):
    def get(self, request):
        params = {}
        params['name'] = 'Django'
        return render(request, 'base.html', params)

urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin
from tweets.views import Index
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^$', Index.as_view()),
    url(r'^admin/', include(admin.site.urls)),
)

Traceback:

Please, give an advice, what should i change to get rendered page?

Answer 1

I'm not familiar with the book you are using, so I can't give you any advice based on that. If the book is for Django 1.7, you will find it easier to use Django 1.7 instead of Django 1.8, at least when you are beginning with Django.

If you want to stick with Django 1.8, here's how to fix the error you are currently seeing:

Your settings.py file has a mixture of old templates settings, like TEMPLATE_DIRS and TEMPLATE_LOADERS (Django <= 1.7), and the new settings under TEMPLATES (Django 1.8+).

First, remove the old settings TEMPLATE_DIRS and TEMPLATE_LOADERS.

Secondly, it looks as if DIRS is incorrect in your TEMPLATES setting.

Define BASE_DIR, which should be included in settings.py by default when you run ./manage.py startproject

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

Then change TEMPLATES to

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        ...

Answer 2

I had same problem first I tried to solve it with adding path to shortcuts of HTML templates {% extends "base.html" %} to {% extends "foldername/template/base.html" %} it did not work.

After that I add to 'base.html' file in every projects templates folder. It worked for me.
