How do I override the controller name for a rails url helper?

I have an Post model with a category attribute and corresponding PostsController.

I would like to override the default url helper to produce the folowing:

@post = Post.create(category: 'posts')
<%= link_to 'Post Link', @post %>
# /posts/1

@post = Post.create(category: 'articles')
<%= link_to 'Article Link', @post %>
# /articles/2

I would like to call the default url helper for Post but have it create different urls based upon the category column.

Update

I ended up overriding the url helpers:

module PostsHelper
  def post_path(post, options={})
    self.send("#{post.category}_path", post, options)
  end

  def post_url(post, options={})
    self.send("#{post.category}_url", post, options)
  end
end

Named Routes is what you want:

get 'posts/:id', to: 'posts#<controller-action>', as: 'posts'

<%= link_to 'Post Link', posts_path(@post) %>

get 'articles/:id', to: 'posts#<controller-action>', as: 'articles'

<%= link_to 'Article Link', articles_path(@post) %>
