Rails routing - custom routes for Resources

Question

I'm building currently one Rails app and I'd like to stick to all those fancy things like REST and Resources, but I'd like to customise my routes a little. I want my GET route to be little more verbose - the app I'm creating is a simple blog, so instead of GET /posts/1 I'd prefer something like GET /posts/1-my-first-post .

Any ideas how to do this? Didn't find anything on the web.

Answer 1

Routes:

map.resources :posts

Model:

class Post < ActiveRecord::Base
  def to_param
    "#{id.to_s}-#{slug}"
  end
end

Should do the trick.

Answer 2

Define a to_param method in your Model and all the url helpers will youse what you return with that method, eg:

class Post < ActiveRecord::Base
  der to_param
    slug
  end
end

You will also need to adapt your controllers for that. Replace:

Post.find(params[:id])

with:

Post.find_by_slug(params[:id])

Also note that the find method raises ActiveRecord::RecordNotFound exception when the record can't be found while using the find_by_* method no Exceptions will be raised so you need to check that manually.

您可以找到friendly_id插件很有用，因为它还可以处理重定向，如果您重命名slug（因此seo友好），处理名称冲突并与find方法无缝集成，因此您不需要触摸您的控制器方法（重定向除外）啄）。

Answer 4

Alternatively...

Add a method like this to application_helper.rb

def permalink(post)
  "#{post_path(post)}-#{post.slug}"
end

Then use the following in your views (using permalink(@post) instead of post_path )

<%= link_to @post.title, permalink(@post) %>

Alternatively...

Add a method like this to post.rb

def path
  "/posts/#{id}-#{slug}"
end

Then use the following in your views:
