grails 2+ url mapping specific rules

Question

EDIT

I had forget a "/" so it is actually working. I don't remove this post as it might be useful for others

I have read many SO answer about grails urlMapping but didn't find any answer that fit my needs.

Let say I have two Domain: Project and Contributor

class Project{
   String name;
   String urlName; //is the name converted to url
   static belongsTo = [contributor: Contributor]
}

//a contributor has many Projects, then in the `Project` 
//table I have `contributor_id`
class Contributor{
    String userName;
    static hasMany = [projets: Project]
}

My urls looks like this:

www.mysite.com/frank/frank-s-nice-project/comments
www.mysite.com/bill/bill-s-great-project/comments
www.mysite.com/lucie/lucie-s-awesome-project/comments

Which is corresponding to : www.mysite.com/username/urlName/comments

username comes from Contributor Domain. urlName comes from Project Domain

How can I set urlMappgings.groovy to always redirect to the same controller/action when url matches "/$username/$urlName/comments"

I have tried like this but with no success.

static mappings = {
    "/$username/$urlName/comments"(controller: 'comment', action: 'index)
}

Thanks for your help.

Answer 1

I answer my question to make it as accepted answer,

This actually works

static mappings = {
    "/$username/$urlName/comments"(controller: 'comment', action: 'index)
}
