Building a website with SEO considerations leads to have slugs in the urls.
There is the trivial case of /products/256-my-great-product easily done
changing Product#to_param. But there many others cases not as trivial.
Considering the route (i use a plain match-like route instead of resourcesfor
the example) :
get "/products/:type_slug/:brand_slug/:token-:slug", :to =>
"controller#action", :as => "product"
*I'd add that the id is in fact a md5-like id (NoSQL : mongodb,
couchdb....), so we want naturally use a short token.*
Obviously, link_to("My product", @myproduct), url_for(@myproduct) and
product_path(@myproduct) fail.
To generate such a route, we need to do :
product_path(:type_slug => product.type_slug, :brand_slug =>
product.brand_slug, :token => product.token, :slug => product.slug)
So here is the thing. Doing link_to("My product", @myproduct),
url_for(@myproduct) and product_path(@myproduct) is nice.
If we manually define :
class Product
def to_params
{
:token => token,
:slug => slug,
:brand_slug => brand_slug,
:type_slug => type_slug
}
endend
Then we could use product_path(@myproduct.to_params).
And if the named url helpers recognize that our object respond_to?
:to_params, using this #to_params-returned Hash to build the url, we could
use product_path(@myproduct). For now, a named url helper is just basically
replacing the dynamic url segments from left to right by its arguments from
first to last, applying them a #to_param.
And if the polymorphic_url recognize that our object respond_to? :to_params,
passing this #to_params-returned Hash to the named url helper, we could use
link_to("My
product", @myproduct), url_for(@myproduct).
Just enough to be nice. And SEO-friendly without pain.
Waiting for comments, thoughts and anything else helpful :)
Maxime.
