default URL for a model in rails?
I have a class Post
I want the default URL of each posts to be http://domain.com/9383 instead of http://domain.com/posts/9383
I tried to fix it in the routes. I manage to accept domain.com/222 but if I use <%= url_for(@posts) %> I still get domain.com/po开发者_如何学Csts/222
How can I do it? Thank you
You can't change the behaviour of url_for(@post)
with routes. url_for
will assume a map.resources
setup if an ActiveRecord
instance is passed to it.
You should rather do this:
# routes.rb
map.post ":id", :controller => "posts", :action => "show"
# named route
post_path(@post)
# full link_to
link_to @post.title, post_path(@post)
If you're using url_for
, there's no way to tell it to omit the /posts/
section. I think you would need to create helper, maybe in application_helper.rb
def post_url(post)
"/#{post.id}"
end
Overriding url_for
seems to not be considered a best practice in Rails, although it seems terribly convenient to me. Here's a description of how to do it by customizing ApplicationController
