对 Django 模板的更改未反映出来
Changes to Django Template is not reflecting
我按照 https://github.com/tomwalker/django_quiz 上的说明使用了这个项目。
我能够成功地使用该项目。
但是，当我更改模板（.html 文件）时，没有任何变化。即使我添加或删除全部内容。我不确定我是否遗漏了什么。
我签入了 views.py，但看不到任何 html 渲染。我是 Django 的新手，发现很难理解 views.py 并对模板（如问题或类别）进行任何更改。任何帮助将不胜感激。
有趣的是，如果我对原始 base.html 进行任何更改，则会应用 css 和样式以及 base.html
中的任何其他更改

当我对 etbox/templates/base.html 进行更改时，我的更改会反映在所有测验中 Html(s).
我只是快速浏览了一下，在 views.py 中他似乎只使用了通用视图，这就是他从不直接调用渲染函数的原因。
因此，正如您在 urls.py 中看到的那样，主页与来自 views.py 的 QuizListView 相关联 QuizListView 继承自 django.views.generic.ListView
如果您查看文档，您会发现默认的模板名称是您指定的模型名称 + '_list'
class QuizListView(ListView):
model = Quiz
def get_queryset(self):
queryset = super(QuizListView, self).get_queryset()
return queryset.filter(draft=False)
此模板位于此路径中：django_quiz/quiz/templates/quiz/quiz_list。html
对其进行编辑，当您刷新页面时，所做的更改应该反映在浏览器中
这就是您的 link 和模板应该 link 的方式：
您首先在名为 urls.py:
的应用程序目录文件夹中创建一个 url 地址
"""Defines the URL patterns for app created within django"""
from django.conf.urls import url
from . import views
urlpatterns = [
# Home page
url(r'^$', views.index, name='index'),#notice how I mention the function called index within the views.py file
...
]
然后在与 urls.py 相同的文件夹中添加一个函数，允许将模型和表单中的信息传输到模板中（但这是可选的）。
def index(request):
"""Creating a homepage view"""
return render(request, '#app_name/index.html')
创建 .html 文件时，请记住它应该位于特定位置以便 django 读取它。这很可能是您的问题。您的 .html 文件不在 Django 呈现它的正确位置。
这是 .html 文件从主项目目录开始的一般文件路径。 #main_directory/#django_app_directory/#templates/#django_app_name_folder/.html_file
.所以基本上 .html 文件必须位于与 views.py 和 urls.py 相同的目录中名为 templates 的文件夹中。在 templates 文件夹中，您创建另一个与您的应用名称文件夹同名的文件夹。在此应用程序名称文件夹中，您可以放置 .html 文件。
我按照 https://github.com/tomwalker/django_quiz 上的说明使用了这个项目。 我能够成功地使用该项目。 但是，当我更改模板（.html 文件）时，没有任何变化。即使我添加或删除全部内容。我不确定我是否遗漏了什么。 我签入了 views.py，但看不到任何 html 渲染。我是 Django 的新手，发现很难理解 views.py 并对模板（如问题或类别）进行任何更改。任何帮助将不胜感激。
有趣的是，如果我对原始 base.html 进行任何更改，则会应用 css 和样式以及 base.html
中的任何其他更改urls.py代码

我只是快速浏览了一下，在 views.py 中他似乎只使用了通用视图，这就是他从不直接调用渲染函数的原因。
因此，正如您在 urls.py 中看到的那样，主页与来自 views.py 的 QuizListView 相关联 QuizListView 继承自 django.views.generic.ListView
如果您查看文档，您会发现默认的模板名称是您指定的模型名称 + '_list'
class QuizListView(ListView):
model = Quiz
def get_queryset(self):
queryset = super(QuizListView, self).get_queryset()
return queryset.filter(draft=False)
此模板位于此路径中：django_quiz/quiz/templates/quiz/quiz_list。html
对其进行编辑，当您刷新页面时，所做的更改应该反映在浏览器中
这就是您的 link 和模板应该 link 的方式：
您首先在名为
的应用程序目录文件夹中创建一个 url 地址urls.py:"""Defines the URL patterns for app created within django""" from django.conf.urls import url from . import views urlpatterns = [ # Home page url(r'^$', views.index, name='index'),#notice how I mention the function called index within the views.py file ... ]然后在与
urls.py相同的文件夹中添加一个函数，允许将模型和表单中的信息传输到模板中（但这是可选的）。def index(request): """Creating a homepage view""" return render(request, '#app_name/index.html')创建
.html文件时，请记住它应该位于特定位置以便 django 读取它。这很可能是您的问题。您的.html文件不在 Django 呈现它的正确位置。 这是.html文件从主项目目录开始的一般文件路径。 #main_directory/#django_app_directory/#templates/#django_app_name_folder/.html_file .所以基本上.html文件必须位于与views.py和urls.py相同的目录中名为templates的文件夹中。在templates文件夹中，您创建另一个与您的应用名称文件夹同名的文件夹。在此应用程序名称文件夹中，您可以放置.html文件。
