Hello, in a restful application, I am trying to create the thing mentioned int he subject: link to the association, e.g. /articles/1/comments. The "link\_to 'comments', @article.comments" doesn't do anything good for me... I can get the result via "link\_to 'comments', @article.comments.new", but creating new object just for link generation seems wrong (also, the intention is something completely different, the paths for 'create new comment' and 'comments' just coincide)... I can also get it by "link\_to 'comments', url\_for\_article\_comments( @article )", but I would like to have a shorter version (especially when used in multi-level relationships)... I am currently using Rails 2.0.1. Anybody knows the official way to do it? Could an upgrade of Rails help? izidor ---

I am confused today: link\_to 'comments', article\_comments\_path( @article )" is of course my code. ---

You're talking about nested resources here if I understand that right. So what sense would it make to link the comments index action for a not existing article? Or are you using a namespace article? ---

Eh, I am a bit confused today... Let me try to explain... The @article exists, and Rails could get to it from association object, I presume... I would like to get /articles/1/comments in a shortes possible way. It could be programmed by taking the association object @article.comments, retrieving its parent object, and constructing path. But it doesn't happen currently. The shortest way to get the path is "link\_to 'ccc', [@article, @article.comments.new]", but I don't like it... The correct way is "link\_to 'ccc', article\_comments\_path( @article )", but it is long (especially for multi-level paths)... izidor
