[英]Help convert a nested route to Rails 3
I have a comment form (in comments/_form.html.erb) that I use in my other controllers (posts and tags). 我有一个评论表(在comments / _form.html.erb中),我在其他控制器(帖子和标签)中使用。
<% form_for([@post, Comment.new], :html => { :multipart => true }) do |f| %>
<%= f.text_field :commenter %>
<%= f.text_field :email %>
<%= f.text_area :body %>
<%= f.submit 'submit' %>
<% end %>
In my Comment model I have: 在我的评论模型中,我有:
belongs_to :post
In the rails 2 version of my application my routes.rb
included map.resources :posts, :has_many => :comments
which worked fine but the same configuration in Rails 3 throws an undefined method error: 在我的应用程序的rails 2版本中,我的
routes.rb
包括map.resources :posts, :has_many => :comments
工作正常但Rails 3中的相同配置引发了未定义的方法错误:
undefined method `post_comments_path' for #<#<Class:0xf94920>:0xf8d540>
I thought Rails 2.x routes were just depreciated until 3.1 comes out. 我认为Rails 2.x路线只是折旧,直到3.1出来。 How do I convert this to Rails 3?
我如何将其转换为Rails 3? Thanks for reading my question.
感谢您阅读我的问题。
In Rails 3, you can define nested routes as such: 在Rails 3中,您可以定义嵌套路由:
resources :posts do
resources :comments
end
I think you may also need to define form_for a little differently: 我想你可能还需要以不同的方式定义form_for:
<%= form_for [:post, @comment] do |f| %>
