Question

我正在关注用于部署我的应用程序的两个django和mozilla教程。我设置了虚拟环境和基本设置，本地设置等，当我运行命令时：

./manage.py runserver 0:8000 --settings=Books.settings.local

浏览器显示错误，找不到模板主页... 我认为由于env可能存在一些问题，我不确定。

Template-loader postmortem

Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.filesystem.Loader: /home/user/workspace/Books/Books/templates/home.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/django/contrib/admin/templates/home.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/django/contrib/auth/templates/home.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/star_ratings/templates/home.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/crispy_forms/templates/home.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/user/workspace/Books/venv/lib/python3.6/site-packages/debug_toolbar/templates/home.html (Source does not exist)

我还更新了manage.py，如下所示：

import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Books.settings.local")

Answer 1

这一行：

BASE_DIR = os.path.dirname（os.path.dirname（os.path.abspath（__ file __）））

将BASE_DIR指定为base.py所在的当前目录的父目录。这意味着BASE_DIR将引用/home/user/workspace/Books/Books/

你应该试试这个：

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

然后在TEMPLATES:：

TEMPLATES = [
    {
        ...
        'DIRS': [os.path.join(PROJECT_ROOT,'templates')],
        ...
]

本地开发期间'TemplateDoesNotExist at /'错误
