Rails:立即渲染并退出

Question

使用omniauth gem,无论提供者如何,我都被迫为成功登录定义单个路由回调:

def auth_callback 

        auth_data = request.env['omniauth.auth']

        if auth_data.has_key('something')
            process_one(auth_data)
        else
            process_two(auth_data)
        end

        # No view is available here

end


def process_one
    # do something then render view for process_one
    return
end

def process_two
    # do something then render view for process_two
    return
end

如何防止控制器返回到auth_callback方法并尝试显示相应的视图(不存在)？一旦process_one或process_two方法返回,则应将处理视为完成.

为什么不专门打电话给render那些方法呢？

def process_one
 # do something then render view for process_one
 render :process_one and return
end

Rails应该检测到你已经运行它而不是尝试再次渲染.
