[英]Rails 3 link_to routes (edit) nested resources
Sorry if this has been asked elsewhere, but I can't figure this out. 对不起,如果有人在其他地方询问,但我无法弄清楚这一点。 I have a forum with sections, topics, and replies. 我有一个论坛,其中包含部分,主题和回复。 I'm trying to edit and delete replies from the show topic view. 我正在尝试编辑和删除show topic视图中的回复。 This is the structure: 这是结构:
resources :sections do
resources :topics do
resources :replies
end
end
So I do a rake routes to see where I'm linking my edit reply. 所以我做了一个rake路线,看看我在哪里链接我的编辑回复。 I see that its edit_section_topic_reply and in my link_to I add _path to it. 我看到它的edit_section_topic_reply和我的link_to中我添加了_path。 Now this is what I can't figure out. 现在这是我无法弄清楚的。 What parameters am I passing it? 我通过什么参数? Shouldn't it be: 不应该是:
<%= link_to 'Edit', edit_section_topic_reply_path(@reply, @topic, @section) %>
I get a ActionController::RoutingError
in Topics#show
when I do this. 当我这样做时,我在Topics#show
得到一个ActionController::RoutingError
。
No route matches {:topic_id=>#<Topic id: 2, section_id: 2, user_id: nil, subject: "subject", body: "body", created_at: "2011-03-04 08:37:37", updated_at: "2011-03-04 21:37:16">, :controller=>"replies", :action=>"edit", :section_id=>nil, :id=>#<Section id: 2, name: "Section", description: "Section Description", created_at: "2011-03-04 07:50:56", updated_at: "2011-03-04 07:50:56">}
It seems like it isn't passing IDs, but the nest before, my new topic works fine 好像它不是传递ID,而是之前的巢,我的新主题运行正常
new_section_topic_reply_path(@topic, @section)
I really dislike this aspect of the link_to
helper. 我真的不喜欢link_to
帮助器的这个方面。 In the interest of making your code more readable and less prone to error, I would suggest that you be explicit about which IDs you are passing in. 为了使您的代码更具可读性并且不易出错,我建议您明确说明您传入的ID。
<%= link_to 'Edit', edit_section_topic_reply_path(:id => @reply.id,
:topic_id => @topic.id,
:section_id => @section.id) %>
I've run into too many subtle and seemingly insane bugs due to params being out of order in a link_to
. 由于params在一个link_to
出现故障,我遇到了太多微妙而看似疯狂的错误。
编辑链接的另一种方法
<%= link_to [:edit,@section,@topic,@reply] %>
我认为正确的顺序应该是:
<%= link_to 'Edit', edit_section_topic_reply_path(@section, @topic, @reply) %>
