Python CSS静态文件在Django中不起作用，我是Django的初学者，main.CSS属性未应用于my store.html

这是在settings.py中添加的

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
] 

from django.urls import path
from . import views
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    path('', views.store, name="store"),
]

urlpatterns += staticfiles_urlpatterns()

from django.shortcuts import render
from django.template.context import RequestContext

def store(request):
    context ={}
    return render(request, 'store/store.html',context)

url.py

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
] 

from django.urls import path
from . import views
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    path('', views.store, name="store"),
]

urlpatterns += staticfiles_urlpatterns()

from django.shortcuts import render
from django.template.context import RequestContext

def store(request):
    context ={}
    return render(request, 'store/store.html',context)

视图.py

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
] 

from django.urls import path
from . import views
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    path('', views.store, name="store"),
]

urlpatterns += staticfiles_urlpatterns()

from django.shortcuts import render
from django.template.context import RequestContext

def store(request):
    context ={}
    return render(request, 'store/store.html',context)

store.html

{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'css/main.css' %}">

<h3>store</h3>

<img src="{% static 'images/cart.png' %}">

文件夹树

商店->商店->商店.html

{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'css/main.css' %}">

<h3>store</h3>

<img src="{% static 'images/cart.png' %}">

static->css->main.css

body{
    background-color: blue;
}

---

static->images->cart.png

代码看起来很干净，但有一个地方你显然忽略了。也许我们可以通过将下面的细节与您的项目进行比较来找到解决方案

设置.py

INSTALLED_APPS = [.., 
                  'your_app',]  
...

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

...

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static")
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static'), ]

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'media') 

url.py

    urlpatterns = [
        path('admin/', admin.site.urls),
        path('', IndexView.as_view(),name='index'),
    ]
    
    if settings.DEBUG:
        urlpatterns = urlpatterns + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
        urlpatterns = urlpatterns + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

models.py

class Task(models.Model):
    user = models.ForeignKey("auth.User", on_delete=models.CASCADE)  
    title = models.CharField(max_length=150)
    content = RichTextField()
    created_date = models.DateTimeField(auto_now_add=True)  
    slug = models.SlugField(editable=False)

    def __str__(self):
        return self.title

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(Task, self).save(*args, **kwargs)

views.py

    class IndexView(ListView):
        template_name = 'task/index.html'
        model = Task
        context_object_name = 'task'
    
        # paginate_by = 7
    
        def get_context_data(self, *, object_list=None, **kwargs):
            context = super(IndexView, self).get_context_data(**kwargs)
            return context

如果要在html文件中使用静态文件，必须指定如下内容：

.html

{%load static%}
....

Templates文件夹树=>Templates->task->index.html

静态文件夹树=>Static->css->file.css

---

=>static->css->file.css

是否检查并确保文件链接正确？它不是“/static/css/main.css”吗？
