Rails - Oct 2005 - Helpers, recursion

I need some advice on how to best solve this problem without repeating
myself too much and not writing hacked-up HTML in my helper (unless
that''s acceptable).

Here''s what I''ve got so far:

My controller
	@project = Project.find(params[''id'']

My view

<%=display_recursive_tasks(@project) %>

(my helper)


  def display_recursive_tasks(project)
  
    ret = "<blockquote>"
    ret += display_tasks_for_project(project)
    for child in project.children
      ret += display_recursive_tasks(child)
    end
    ret += "</blockquote>"
    return ret
  end
  
  def display_tasks_for_project(project)
    
    ret = ""
    for task in project.tasks
      link = link_to task.name, :controller=>''task'',
:action=>''show'',
:pid=>project.id, :id=>task.id
      ret += "#{link}<br />" 
    end
      
    return ret
  end


What I would like to do is actually display a table of information (the
name, esthorus, due_on, priority, status) for each task.  I could just
render the html code right there, but is there a better way to do that,
like with a partial or component?

Thanks in advance to anyone who can help.

Hi Brian,

I was looking for help with recursion, so thanks for putting this out
there... my only comment per your message, though, is not to use
<blockquote> for indentation. Use it for blockquotes. If you want to
show hierarchy using indentation, use nested lists or something and
apply margins to them using CSS.

If you had nested ULs, for instance, the following:

ul ul {margin: 0 0 0 2em}

Would put a 2em left margin on each successive level, and since each
would already be within one that is indented, the hierarchy should
show.

:)

Yeah.... I know that the blockquote was a bad thing to do and being a
standards-guy, I know it was a cop-out, but I was running into some
validation issues with nested lists in my recursive loop and I needed to
post the question

(which never got answered by the way!)
