我试图将paginate链接到我的嵌套路由而不是常规的posts变量。 我知道我应该将一些参数传递给分页，但我不知道如何传递它们。 
 
 基本上有一个存储在@posts的数组，另一个param paginate可以访问的是category_id 。 
 
 嵌套路线是/category/1/posts但是在下一个和之前打开将paginate返回一个类似这个posts?page=1&category_id=7的网址posts?page=1&category_id=7 。 
 
 <%= will_paginate @most_recent_posts "What do I do here?" %>
 
 
 这是Yannis回答的结果： 
 
 在您的控制器中，您可以： 
 
@posts = @category.posts.paginate
 
 在你看来： 
 
<%= will_paginate(@post) %>
 
 这样做会出现以下URL 
 
posts?page=2&post_category_id=athlete_management
 
 
 routes.rb＃有更多的路线，但这些是相关的路线 
 
map.resources :posts
map.resources :post_categories, :has_many => :posts
 
 解 
 
 map.resources :post_categories do |post_category|
   post_category.resources :posts
  end
  map.resources :posts 
 
 必须在块之后声明资源 
 
 谢谢斯蒂芬！ 

I'm trying to get will paginate to link to my nested route instead of the regular posts variable. I know I'm supposed to pass some params to paginate but I don't know how to pass them.
 
Basically there is an array stored in @posts and the other param paginate has access to is category_id.
 
The nested route is /category/1/posts but hitting next and previous on will paginate returns a url like this posts?page=1&category_id=7.
 
 <%= will_paginate @most_recent_posts "What do I do here?" %>
 
 
This is the result of Yannis's answer:
 
In your controller you can do:
 
@posts = @category.posts.paginate
 
And in your view:
 
<%= will_paginate(@post) %>
 
Doing this comes up with the following URL
 
posts?page=2&post_category_id=athlete_management
 
 
routes.rb #there are more routes but these are the relevant ones
 
map.resources :posts
map.resources :post_categories, :has_many => :posts
 
solution
 
 map.resources :post_categories do |post_category|
   post_category.resources :posts
  end
  map.resources :posts 
 
Had to declare the resource after the block
 
Thanks stephen!
