我可以重定向到 django TemplateView 中的另一个 url 吗?

问题描述

我有一个如下所示的 url 映射:

url(r'^(?P[a-z][a-z])/$', MyTemplateView.as_view()),

对于 lang 捕获组，我只接受几个值，即:(1) ro 和 (2) en.如果用户输入http://server/app/fr/，我想把它重定向到默认的http://server/app/en/.>

由于 MyTemplateView 只有一个预期返回字典的方法，我该怎么做?

def get_context_data(self, **kwargs):返回{'foo':'等等'}

解决方案

我知道这个问题很老，但我自己才刚刚完成.您可能认为要在 get_context_data 中执行此操作的一个原因是业务逻辑，但您应该将其放在 dispatch 中.

def dispatch(self, request, *args, **kwargs):如果不是 request.user.is_authenticated():返回重定向('家')return super(MyTemplateView, self).dispatch(request, *args, **kwargs)

在您的 dispatch 中保留您的业务逻辑，您应该是金子.

I have a url mapping that looks like this:

url(r'^(?P<lang>[a-z][a-z])/$', MyTemplateView.as_view()),

There are only a few values that I accept for the lang capture group, that is: (1) ro and (2) en. If the user types http://server/app/fr/, I want to redirect it to the default http://server/app/en/.

How can I do this since MyTemplateView only has a method that is expected to return a dictionary?

def get_context_data(self, **kwargs):
    return { 'foo': 'blah' }

解决方案

I know this question is old, but I've just done this myself. A reason you may think you want to do it in get_context_data is due to business logic, but you should place it in dispatch.

def dispatch(self, request, *args, **kwargs):
    if not request.user.is_authenticated():
        return redirect('home')

    return super(MyTemplateView, self).dispatch(request, *args, **kwargs)

Keep your business logic in your dispatch and you should be golden.
