今天我一整天都在摸不着头脑。目前我已经设置了嵌套路由。
resources :activities
resources :users do
resources :timesheets do
end
end
在我的_create.html.erb partial中，我想链接回user_timesheets。目前唯一可以使用的link_to是
user(@timesheet)
链接到用户显示页面（users / 1）
通常我会使用此代码链接回用户的时间表。
(/users/1/timesheets/)
user_timesheets_path(@user, @timesheet)
这是我可以在不抛出错误的情况下开始工作的唯一代码
<%= link_to activity.trackable.user.timesheets.name, activity.trackable.user(@timesheet) %>
这会抛出未定义的方法错误。
我已经尝试过我能想到的每一种组合。我也尝试在我的活动模型中定义@user和@timesheets的实例变量。有什么建议？我错过了什么？
修改 所以我尝试了Rails Guy的答案，但仍然无法工作。这是我的一些代码。
class ActivitiesController < ApplicationController
def index
@activities = PublicActivity::Activity.order("created_at desc")
end
end
我想知道它是否无效，因为我没有指定@user是什么或@timesheet在我的Activities控制器中。我试图这样做但无济于事。

这是我的时间表控制器。但是，当我在我的时间表控制器中查看视图时，一切正常。我想要做的是让他们在我的活动控制器下的活动视图中工作。 （这是我认为我需要做的才能使它工作）。

答案 0 :(得分：0)
我认为必须这样做：
resources :users do
resources :timesheets
end
现在您将能够访问时间表索引方法，如：
user_timesheets_path(@user)
并显示如下方法：
user_timesheet_path(@user, @timesheet)
希望它会有所帮助。谢谢
