javascript - 在我的 django 模板中包含 CSS 和 Javascript

Question

我是 Django 1.5 的新手，我已经了解了一些关于它的基本知识。我的问题是，我无法在我的模板中包含 css 和 javascript。我已经阅读了有关它的文档，但正如我所说。我是新手，看不懂。请帮助我了解在我的 base.djhtml 模板中包含 css 和 javascript 的分步过程。谢谢。

这是我的 settings.py

    # Django settings for myweblab project.

    DEBUG = True
    TEMPLATE_DEBUG = DEBUG

    import os.path

            'PASSWORD': '',

这是我的 url.py

    from django.conf.urls import patterns, include, url
    from django.conf import settings
    from myweblab.views import index

    # Uncomment the next two lines to enable the admin:
    from django.contrib import admin
    admin.autodiscover()

    urlpatterns = patterns('',
        # Examples:
        # url(r'^$', 'myweblab.views.home', name='home'),
        # url(r'^myweblab/', include('myweblab.foo.urls')),

        # Uncomment the admin/doc line below to enable admin documentation:
        # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

        # Uncomment the next line to enable the admin:
         url(r'^admin/', include(admin.site.urls)),
         url(r'^$', index, name="index"),

    )

    urlpatterns += patterns('',
        url(r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.STATIC_URL, 'show_indexes': True}),
    )

和我的 base.djhtml

    <!DOCTYPE >
    <html>
        <head>
            <!-- css and javascript template should be here -->
            <title>
                {% block title %}
                {% endblock %}
            </title>
            <link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
            <script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>
        </head>
        <body>
            {% block content %}
            {% endblock %}
        </body>
    </html>

Answer 1

首先，创建staticfiles文件夹。在该文件夹中创建 css、js 和 img 文件夹。

设置.py

import os

PROJECT_DIR = os.path.dirname(__file__)

DATABASES = {
    'default': {
         'ENGINE': 'django.db.backends.sqlite3', 
         'NAME': os.path.join(PROJECT_DIR, 'myweblabdev.sqlite'),                        
         'USER': '',
         'PASSWORD': '',
         'HOST': '',                      
         'PORT': '',                     
    }
}

MEDIA_ROOT = os.path.join(PROJECT_DIR, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')

STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(PROJECT_DIR, 'staticfiles'),
)

主要网址.py

from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from myweblab import settings

admin.autodiscover()

urlpatterns = patterns('',
    .......
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

urlpatterns += staticfiles_urlpatterns()

模板

{% load static %}

<link rel="stylesheet" href="{% static 'css/style.css' %}">

Answer 2

请参阅有关静态文件的 django 文档。

在settings.py 中：

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

然后将您的js和css文件静态文件夹放在您的项目中。不在媒体文件夹中。

在view.py中：

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

在template.html中：

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

在urls.py中：

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

项目文件结构可以在 imgbin 中找到。

Answer 3

阅读此https://docs.djangoproject.com/en/dev/howto/static-files/：

对于本地开发，如果您使用 runserver 或将 staticfiles_urlpatterns 添加到您的 URLconf，则您已完成设置 - 您的静态文件将自动以 /static/ 的默认（对于新创建的项目）STATIC_URL 提供。

并尝试：

~/tmp$ django-admin.py startproject myprj
~/tmp$ cd myprj/
~/tmp/myprj$ chmod a+x manage.py
~/tmp/myprj$ ./manage.py startapp myapp

然后添加'myapp'到INSTALLED_APPS( myprj/settings.py)。

~/tmp/myprj$ cd myapp/
~/tmp/myprj/myapp$ mkdir static
~/tmp/myprj/myapp$ echo 'alert("hello!");' > static/hello.js
~/tmp/myprj/myapp$ mkdir templates
~/tmp/myprj/myapp$ echo '<script src="{{ STATIC_URL }}hello.js"></script>' > templates/hello.html

编辑myprj/urls.py：

from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView

class HelloView(TemplateView):
    template_name = "hello.html"

urlpatterns = patterns('',
    url(r'^$', HelloView.as_view(), name='hello'),
)

并运行它：

~/tmp/myprj/myapp$ cd ..
~/tmp/myprj$ ./manage.py runserver

有用！
