Question

I’m trying to modify the UI of a Redmine installation (Redmine 0.7.3.devel.2093 (MySQL)).

When you view a project in Redmine, it generates a list of all the subprojects for the project.

For example, app/views/projects/index.rhtml calls the link_to function:

<% if @project_tree[project].any? %>     <p><%= l(:label_subproject_plural) %>:     <%= @project_tree[project].sort.collect {|subproject|         link_to(h(subproject.name), {:action => 'show', :id => subproject}, :class => (User.current.member_of?(subproject) ? 'subp fav' : 'subp'))}.join(', ') %></p> <% end %> 

Which outputs the following HTML:

<p>Subprojects: <a href='/projects/show/foo' class='subp fav'>Foo Subproject</a>, <a href='/projects/show/bar' class='subp'>Bar Subproject</a>, <a href='/projects/show/baz' class='subp fav'>Baz Subproject</a></p> 

We find that a comma-delimited list of subprojects is very difficult to visually parse. We’d like to have each subproject listed on its own line. (Any markup is fine — UL, OL, or P tags on each link would be ideal, but a BR instead of a comma would be totally fine.)

What is the best way to make this change? I can’t find where link_to is defined in the app; grepping for def link_to( and similar turns up nothing. I’m a UI type, so I don’t really get how Rails deals with this stuff — it doesn’t seem to be defined in the view templates.

You can do it directly in the code you provided. Just change

join(', ') 

to

join('<br />') 

That should do it.
