link_to and no route match problem

I have try to use link_to like so:

<%= link_to post.title, {:controller => 'posts', :action => 'show', :id => post.title}, :title => post.title %>

If title contains a period (.), I get the following error:

No route matches {:controller=>"posts", :action=>"show", :id=>"test.title"}

But if no period is included, everything works.

Can anyone help me?

I found the solution.http://www.ruby-forum.com/topic/101911#222985

The solution that you linked is the worst one. Overriding rails internals to fit your problem is wrong. I rather use the gem called friendly_id, this will creates a url proof slug from your id. It's easy to set up and use.

It thinks that in the route it is expecting the format ".title" and that has not been configured. Because your route would look something like this "/posts/test.title" could you not rather use "/posts/test-title" as that is a better url structure for most web servers?

If you do need to hack it, in rails 2 you can use the ":requirements" option like this:

map.connect '/post/:id/:title', :controller => 'forum', :action => 'show_post', :requirements => { :title => /.*/ }

The problem is :title => post.title Try using the post object in there instead.

link_to post.title, :controller => 'posts', :action => 'show', :id => post

or even better

link_to post.title, post
