问题
I currently have URLs which look like this:
things?category_id=6&country_id=17
and I would like to have URLs which look like this:
/printer_cartridges/united_kingdom
Is there a way in Rails 3, without hard coding all of the categories and countries in the router to have the URLs as I would like above, perhaps using find_by_name or the such like? What is the best way to approach this?
回答1:
match '/:category_slug/:country_slug', :to => 'things#index'
Then you'll need to update your action to look up everything using params[:category_slug] and params[:country_slug] instead of the ids. Look at the slugged gem to generate slugs.
回答2:
In your category model add the method
def to_param
"#{category_name.parameterize}/#{location_name.parameterize}"
end
where category_name and location_name are where you input where you have have the names stored.
