Im making forum and i have problem with paths.

Here is code:
http://pastie.caboo.se/6389

With this code, it works. But its a bit weird to use so many paths

me something.

Try using named routes, and then you can use the magic named route URL
helper methods.

routes.rb:

map.with_options(:controller => ‘forum’) do |m|
m.category ‘/forum/show_category/:id’
m.forum ‘/forum/show_forum/:id’
m.title ‘/forum/show_title/:id’
end

show_topic.rhtml

<%= link_to category_url(@list.first.forum.category) %> >>
<%= link_to forum_url(@list.first.forum) %> >>
<%= link_to topic_url(@list.first) %>

The named URL helpers act like url_for, but generate the URL using the
corresponding named route. You can pass arguments that get mapped to the
URL params in order, or using a hash for the mapping.

Ooops, I messed up the named routes. Need the :action requirement.

It is almoust what i wanted. But if i go to forum or category page or
new topic page, i cant use same function.

When im in topic page, it must show:
Category_name → Forum_name → Topic_name

If im doing new reply i need to get:
Category_name → Forum_name → Topic_name → New_Reply

If im looking for categories i need to get:
Category_name

I just dont know how to do this. Im not going to put like 8 if to
function?
There just must be a better way…

I have done something similar with a system of categories,
subcategories, products.

It involves methods to call url_for with the proper options, and some
routes

Code here: Parked at Loopia

It allows you to do product_url(@product), which will generate:
“/products/parent_cat/sub_cat/1”

and category_url(@category) which gnereates: “/products/foo” or
“/products/foo/bar” based on wether @category is a parent or a child.
