[英]Rails Nested Route For Singular Resource
I have a nested route on a singular resource 我在单一资源上有一个嵌套路由
map.resource :account, :controller => "users" do |page|
page.resources :feeds
end
I'm trying to make a form to add a feed. 我正在尝试制作一个表单来添加Feed。 I start with this...
我从这开始......
<% form_for @feed do |f| %>
undefined method `feeds_path' for #<ActionView::Base:0x2123174>
So I try 所以我试试
<% form_for [current_user,@feed] do |f| %>
undefined method `user_feeds_path' for #<ActionView::Base:0x20b3e00>
I guess that is due to renaming it from "users" to "account"? 我想这是因为将它从“用户”重命名为“帐户”? So I tried
所以我试过了
<% form_for account_feeds_path(@feed) do |f| %>
`@/account/feeds.%23%3Cfeed:0x22ea5c0%3E' is not allowed as an instance variable name
Not sure what that error means. 不确定该错误意味着什么。 So I've resorted to using doing this which works:
所以我已经使用了这样做:
<% form_for @feed, :url=>{:action=>:create} do |f| %>
Is that really the best way? 这真的是最好的方式吗? In other words, is there no way to use named routes in this situation?
换句话说,在这种情况下是否无法使用命名路由?
I think what you want to do is 我想你想做的是
<% form_for [:account, @feed] do |f| %>
form_for will then look to use the account_feeds_path with POST when @feed is a new record and account_feed_path(@feed) with PUT when @feed is not a new record. 当@feed是新记录时,form_for将使用带有POST的account_feeds_path,当@feed不是新记录时,将使用PUT将account_feed_path(@feed)用于。
I think you're getting confused here about nested (+named) routes and singular resources. 我认为你在这里对嵌套(+命名)路由和奇异资源感到困惑。 I'm guessing that what you're trying to do is have a singular
feed
resource that belongs to a user (account), right? 我猜你正在尝试做的是拥有一个属于用户(帐户)的单一
feed
资源,对吧?
If so, your existing routes 如果是这样,您现有的路线
map.resource :account, :controller => "users" do |page|
page.resources :feeds
end
should perhaps be 也许应该是
map.resources :accounts, :controller => "users" do |account|
account.resource :feed
end
Note that accounts
are plural resources, but the feed is singular. 请注意,
accounts
是多个资源,但Feed是单数。 That gives you the usual RESTful routes on your accounts (ie your users)... but a singular 'feed' resource. 这为您的帐户(即您的用户)提供了通常的RESTful路线......但这是一个单一的“Feed”资源。 You won't need to refer to the id of your feed - but usually just work from the @account.feed
您无需参考Feed的ID - 但通常只需使用@ account.feed即可
use rake routes
to show you the full list of routes that this creates. 使用
rake routes
向您显示此创建的路由的完整列表。
account_feed_path(@account)
, for instance will give you the Show page for a feed. 例如,
account_feed_path(@account)
将为您提供Feed的显示页面。
The paths therefore give you the ability to use form helpers like so: 因此,路径使您能够使用表单助手,如下所示:
<% form_for :feed, account_feed_path(@account) do |f| %>
<% end %>
