Question

I have a store model with the following:

  def to_param
    slug + "-info"
  end

The urls will be like:

/dell-info
/ibm-info
/apple-info

My route for this is clearly wrong:

match '/:slug-info' => 'stores#info', :as => :stores

How can I fix this? If I use match '/:slug(-info)' as the route it works but matches BOTH /dell and /dell-info

Answer 1

You could add some constraints to the route and then strip off the “-info” in your controller:

match '/:slug' => 'stores#info', :as => :stores, :constraints => { :slug => /-info$/ }

and then, in your controller:

def info
  slug = params[:slug].sub(/-info$/, '')
  #...
end

Or better, have a method on your model that can remove the “-info” suffix while it looks up an object based on the slug:

# In the model
def self.for_slug(slug)
  slug = slug.sub(/-info$/, '')
  find_by_slug(slug)
end

# In the controller
def info
  thing = Thing.for_slug(params[:slug])
  #...
end
