我在这里看到了类似的例子。但这对我不起作用。我想为帖子创建/提交活动。有几天下一个帖子。并且活动在特定日期下。请参阅下面的模型。
楷模：
class Post < ActiveRecord::Base
has_many :dayinposts
has_many :activitys, :through => :dayinposts
end
class Dayinpost < ActiveRecord::Base
belongs_to :post
has_many :activitys
end
class Activity < ActiveRecord::Base
belongs_to :dayinpost
end
路线：
resources :posts do
resources :dayinposts do
resources :activitys
end
end
耙路线
post_dayinpost_activitys GET /posts/:post_id/dayinposts/:dayinpost_id/activitys(.:format) activitys#index
POST /posts/:post_id/dayinposts/:dayinpost_id/activitys(.:format) activitys#create
显示.html.erb
<% @post.dayinposts.each do |dayinpost| %>
<% dayinpost.activitys.each do |activity| %>
<p>
<b>Action:</b>
<%= activity.action %>
</p>
<% end %>
<%= form_for([@post, dayinpost, dayinpost.activitys.build]) do |f| %>
<div class="field">
<%= f.label :action %><br />
<%= f.text_field :action %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
<% end %>
错误
undefined method `post_dayinpost_activities_path' for #<#<Class:0x40cb6d8>:0x40c9890>
但我在 rake 路线中看到了它......在此先感谢！
