AttributeError: 'LoginForm' 对象没有属性 'get' 并且 response.get('X-Frame-Options') 不是 None

Question

无论我以何种方式实现表单，我都会收到以下错误。 当我转到表单的 URL 时会发生这种情况。 当我转到仪表板时，我需要先登录，然后显示错误，这是我的控制台服务器

在您的urls.py您确实将表单称为视图：

from django.contrib import admin
from django.urls import path
from django.conf.urls import include,url
from .core.urls import urlpatterns as core_urls
from .dashboard.urls import urlpatterns as dashboard_urls
from .authentication.urls import urlpatterns as authentication_urls
from .authentication.views import LoginForm

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r"^",include(core_urls)),
    path('login/', LoginForm),
    url(r"^dashboard/", include((dashboard_urls, "dashboard"), namespace="dashboard")),
]

但是一个Form不能用作视图，需要参考login_view ：

from django.contrib import admin
from django.urls import path
from django.conf.urls import include,url
from .core.urls import urlpatterns as core_urls
from .dashboard.urls import urlpatterns as dashboard_urls
from .authentication.urls import urlpatterns as authentication_urls
from .authentication.views import login_view

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r"^",include(core_urls)),
    path('login/', login_view),
    url(r"^dashboard/", include((dashboard_urls, "dashboard"), namespace="dashboard")),
]
