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) 

Il mio file settings.py:

import os 

SETTINGS_PATH = os.path.dirname(__file__)

I provato a cambiare settings.py in questo modo:

mutato settings.py:

import os 

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) 
TEMPLATE_PATH = os.path.join(BASE_DIR, "templates")

    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'tweets', 
) 

MIDDLEWARE_CLASSES = (

    'django.contrib.messages.middleware.MessageMiddleware', 
    'django.middleware.clickjacking.XFrameOptionsMiddleware', 
    'django.middleware.security.SecurityMiddleware', 
) 

ROOT_URLCONF = 'mytweets.urls' 

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

       'django.template.context_processors.request', 
       'django.contrib.auth.context_processors.auth', 
       'django.contrib.messages.context_processors.messages', 
      ], 
     }, 
    }, 
] 

WSGI_APPLICATION = 'mytweets.wsgi.application' 

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.sqlite3', 
     'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), 
    } 
}

STATICFILES_DIRS = (
    os.path.join(
     os.path.dirname(__file__), 
     'static', 
    ), 
) 

La mia struttura del progetto:

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:

prega, dare un consiglio, che cosa devo cambiare per ottenere page reso?

Answer 1

Non ho familiarità con il libro che stai utilizzando, quindi non posso darti alcun consiglio basato su quello. Se il libro è per Django 1.7, sarà più facile usare Django 1.7 invece di Django 1.8, almeno quando inizi con Django.

Se si vuole attaccare con Django 1.8, ecco come risolvere l'errore che si sta vedendo:

Il file settings.py ha una miscela di vecchie impostazioni modelli, come TEMPLATE_DIRS e TEMPLATE_LOADERS (Django < = 1.7), e le nuove impostazioni sotto TEMPLATES (Django 1.8+).

Innanzitutto, rimuovere le vecchie impostazioni TEMPLATE_DIRS e TEMPLATE_LOADERS.

In secondo luogo, sembra che DIRS non sia corretto nell'impostazione TEMPLATES.

Definire BASE_DIR, che dovrebbe essere incluso nel settings.py per impostazione predefinita quando si esegue ./manage.py startproject

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

Poi cambiare TEMPLATES a

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

Answer 2

Impostare il percorso del modello in DIR [] di impostazioni.py

TEMPLATES = [ 
    { 
     'BACKEND': 'django.template.backends.django.DjangoTemplates', 
     'DIRS': [**'C:\\Python27\\Lib\\site-packages\\django\\contrib\\admin\\templates\\admin'**], 
     'APP_DIRS':True, 
     'OPTIONS': {
