  1. POUsing helpers in rails 3 to output html
    text
    copied!<p>I'm trying my best to build a helper that outputs a &lt;'ul> consisting of all the members of a collection. For each member of the collection I want to print out a &lt;'li> that has a title, and a div of links to CRUD the member. This is pretty similar to what Rails outputs for scaffolding for the index view.</p> <p>Here is the helper I've got:</p> <pre><code>def display_all(collection_sym) collection = collection_sym.to_s.capitalize.singularize.constantize.all name = collection_sym.to_s.downcase html = '' html &lt;&lt; "&lt;ul class=\"#{name}-list\"&gt;" for member in collection do html &lt;&lt; content_tag(:li, :id =&gt; member.title.gsub(' ', '-').downcase.strip) do concat content_tag(:h1, member.title, :class =&gt; "#{name}-title") concat link_to 'Edit', "/#{name}/#{member.id}/edit" concat "\|" concat link_to 'View', "/#{name}/#{member.id}" concat "\|" concat button_to 'Delete', "/#{name}/#{member.id}", :confirm =&gt; 'Are you sure? This cannot be undone.', :method =&gt; :delete end end html &lt;&lt; '&lt;/ul&gt;' return html end </code></pre> <p>And that output exactly what I want. First of all, if anybody thinks there's a better way to do this, please feel free to correct me, I suspect that I'm doing this in a bass ackwards way, but at the moment its the only way I know how.</p> <p>I then attempted to wrap the links in a div as follows:</p> <pre><code>def display_all(collection_sym) collection = collection_sym.to_s.capitalize.singularize.constantize.all name = collection_sym.to_s.downcase html = '' html &lt;&lt; "&lt;ul class=\"#{name}-list\"&gt;" for member in collection do html &lt;&lt; content_tag(:li, :id =&gt; member.title.gsub(' ', '-').downcase.strip) do concat content_tag(:h1, member.title, :class =&gt; "#{name}-title") concat content_tag(:div, :class =&gt; "links-bar") do concat link_to 'Edit', "/#{name}/#{member.id}/edit" concat "\|" concat link_to 'View', "/#{name}/#{member.id}" concat "\|" concat button_to 'Delete', "/#{name}/#{member.id}", :confirm =&gt; 'Are you sure? This cannot be undone.', :method =&gt; :delete end end end html &lt;&lt; '&lt;/ul&gt;' return html end </code></pre> <p>However, I now no longer get any of the markup inside the div.links-bar output to the view. I'm sure this must have something to do with block and bindings, but I can for the life of me figure out what or how to go about fixing it. Can anybody offer any help?</p>
