Django 上下文处理器不工作？

Question

我制作了一个无法工作的 Django 上下文处理器...它还显示警告 messages.First 将向您显示警告消息：-

WARNINGS: ?: (1_8.W001) The standalone TEMPLATE_* settings were deprecated in Django 1.8 and the TEMPLATES dictionary takes precedence. You must put the values of the following settings into your default TEMPLATES dict: TEMPLATE_CONTEXT_PROCESSORS.

现在，我已经用这种方式创建了 mym 自定义上下文处理器

在settings.py中：-

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "cms.utils.context_processors.permission_based_hidding_of_sidebar"
)

并在自定义上下文处理器 utills 中创建了我的函数：-

from django.shortcuts import render, redirect, get_object_or_404
from django.contrib.auth.decorators import login_required
from django.views.decorators.csrf import csrf_exempt
from cms.models.cmsUser import CmsUser
from cms.models.masterUsersPermissionTabMappings import MasterUsersPermissionTabMappings

@login_required
@csrf_exempt
def permission_based_hidding_of_sidebar(request):
    cms_user = CmsUser.objects.get(userId=request.user.id)
    print cms_user.id
    universityPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=1)
    cmsUserPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=2)
    promotedPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=3)
    appUserPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=4)
    newsPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=5)
    emailPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=6)
    pushPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=7)
    chatPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=8)
    frontendPermission = MasterUsersPermissionTabMappings.objects.filter(userId=cms_user).get(permissionTypeId=9)
    print universityPermission
    a='hello'

    return render(request,'templates/admin_user_management/admin_user_add.html',{
        'universityPermission':universityPermission,'cmsUserPermission':cmsUserPermission,
        'promotedPermission':promotedPermission,'appUserPermission':appUserPermission,
        'newsPermission':newsPermission,'emailPermission':emailPermission,'pushPermission':pushPermission,
        'chatPermission':chatPermission,'frontendPermission':frontendPermission,'sayHello':a
    })

我正在尝试在我的观点中使用它来查看它：-

return render(request,template-name,{},context_instance=RequestContext(request))

它向我显示错误 context_instance 未在 views.Is 中定义我可以通过任何方式在视图中使用它。

Answer 1

您的 permission_based_hidding_of_sidebar 方法看起来像一个视图，而不是上下文处理器。模板上下文处理器应该 return 字典，而不是来自 render() 的 HTTP 响应。使用 login_required 或 csrf_exempt 装饰器没有意义。

在您看来，您不需要context_instance=RequestContext(request)，render快捷方式将自动使用请求来呈现模板。

最后，您可以通过更新设置 to use TEMPLATES 来修复 1_8.W001 警告。然后您应该更新 OPTIONS 中的 context_processors，而不是设置 TEMPLATE_CONTEXT_PROCESSORS.
