link_to 'comments', @article.comments ?

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?

Above is typo, I tried "link_to 'comments', [@article, @article.comments.new]....

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)...
