使用 Django 中定义的 URLconf 按以下顺序尝试了这些 URL 模式:

[英]Using the URLconf defined in Django tried these URL patterns in this order:

我有一个 django 应用程序。 以及一些上传功能。

上传 function 的页面正在正确加载。

但是在我提交之后。 我收到此错误:


Page not found (404)
Request Method:     POST
Request URL:    http://127.0.0.1:8000/main/

Using the URLconf defined in schoolfruitnvwa.urls, Django tried these URL patterns, in this order:

    admin/

The current path, main/, didn’t match any of these.

所以这是 views.py

from .forms import ProfileForm
from .models import UploadFile


# Create your views here.
""" def store_file(file):
    with open("temp/hello.png", "wb+") as dest:
        for chunk in file.chunks():
            dest.write(chunk) """


class CreateProfileView(View):
    def get(self, request):
        form = ProfileForm()
        return render(request, "main/create_profile.html", {
            "form": form
        })

    def post(self, request):
        submitted_form = ProfileForm(request.POST, request.FILES)

        if submitted_form.is_valid():
            uploadfile = UploadFile(image=request.FILES["upload_file"])
            uploadfile.save()
            return HttpResponseRedirect("/")

        return render(request, "main/create_profile.html", {
            "form": submitted_form
        })

网址.py:

from django.urls import path

from . import views

urlpatterns = [
    path("", views.CreateProfileView.as_view())
]

forms.py:

class ProfileForm(forms.Form):
    upload_file = forms.FileField()

所以我的问题是:我必须改变什么?

我这样尝试:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('main/', include('main.urls', namespace='main')),
   
]


但是后来我无法运行该应用程序:

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.

在 urls.py 中:

from django.urls import path
from . import views

app_name='main'

urlpatterns = [
    path("", views.CreateProfileView.as_view())
]

主要网址.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('main/', include('main.urls', namespace="app_main")),
   
]

设置.py:


INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'main',
    
]

所以结构看起来像这样:

manage.py 位于文件夹中:schoolfruitnvwa。 在 schoolfruitnvwa 文件夹中,我有主要的应用程序。

您必须检查项目的 urls.py(此文件位于您的 settings.py 附近)中定义的 url 并添加。 小心 Django 得到 urls.py 文件 我不能在开始时有点打扰。

在 urls.py(靠近 settings.py)中::

path('main/', include('youappname.urls', namespace="app_namespace")),

在 urls.py(您的应用程序)中:

app_name = 'yourappname'

urlpatterns = [
    path(...your api function call...),
]

哦,在 html 文件中有站着:/main/

  <form action="/" method="post" enctype="multipart/form-data">
      {% csrf_token %} {{ form }}
      <button type="submit">Upload!</button>
    </form>
