Question

我正在尝试调用此post方法，然后重定向到链接所在的位置，但我正在被路由绊倒。该方法被调用，但就是这样。我做错了什么？

<%= link_to image_tag('notifications3.fw.png', size: "32x32", title: "Notifications", class: 'cr'), activities_path %>

我的路线

resources :activities, path: 'notifications'
post 'activities/read_all_notifications'

js

    $(document).on('click', '.cr', function(e) {
      e.preventDefault();
      return $.ajax('/activities/read_all_notifications', {
        type: "post",
        dataType: "json",
        beforeSend: function(xhr) {
          return xhr.setRequestHeader("X-CSRF-Token", $("meta[name=\"csrf-token\"]").attr("content"));
        },
        cache: false
      });
    });

方法

def index
    @activities = PublicActivity::Activity.order(created_at: :desc)
                                .where(recipient_id: current_user.id, 
                                recipient_type: 'User')
end

def read_all_notifications
    PublicActivity::Activity.where(recipient_id: current_user.id).update_all(:read => true)
    render nothing: true
end

如何更改链接

<%= link_to image_tag('notifications3.fw.png', size: "32x32", title: "Notifications", class: 'cr'), 'activities/read_all_notifications', method: :post %>

并在html中处理它（删除javascript）

# And in the controller 

def read_all_notifications
  PublicActivity::Activity.where(recipient_id: current_user.id).update_all(:read => true)
  redirect_to :activities
end

注意，您可以将路线更改为

resources :activities, path: 'notifications' do
  collection do 
     post :read_all
  end
end

然后，在视图中，您可以使用方法（read_all_notifications_path）来生成网址。从长远来看，这更灵活，更好。

<%= link_to image_tag('notifications3.fw.png', size: "32x32", title: "Notifications", class: 'cr'), read_all_notifications_path, method: :post %>

尝试调用方法并重定向
