Convert from haml to erb - ruby-on-rails-3

Question

I try to convert the code from haml to erb but I'm getting stuck and don't know why.
Here is the original code I want to convert: https://github.com/gmarik/simple-backend-example/blob/master/app/views/backend/resource/_index.html.haml
And here is what I have right now. Can someone take a look at it and give me some hints. Thanks.
I doubt this line the most:
%tr[resource]{odd_or_even}
I think that it might be like:
<tr> <% #resource{odd_or_even} %>
RubyMine gave me an error at this line:
<%= paginate collection %>
<% content_for(:header) do %>
<h1><%= resource_class.model_name.human(count: 2) %></h1>
<ul class="tabs">
<li class="active"><%= link_to "Index", "#" %></li>
<li><%= link_to "New", new_resource_path %> </li>
</ul>
<table class='zebra-striped'>
<thead>
<tr>
<% attributes.each do |attr| %>
<th> <%= resource_class.human_attribute_name(attr) %></th>
<th> </th>
</tr>
</thead>
<tbody>
<% collection.each do |resource| %>
<tr> <% #resource{odd_or_even} %>
<% attributes.each do |attr| %>
<td> <%= resource.public_send(attr).to_s.truncate(20) %> </td>
<td class='row-actions'>
<%= link_to 'show', resource_path(resource) %>
|
<%= link_to 'edit', edit_resource_path(resource) %>
|
<%= link_to 'destroy', resource_path(resource), method: :delete, confirm: "Are you sure?" %>
</td>
<% end %>
</tbody>
</table>
<%= paginate collection %>

Looking at the documentation here : http://haml.info/docs/yardoc/file.REFERENCE.html#object_reference_
I'd say it's :
<tr id="<%= "#{resource.class.name.underscore}_#{resource.to_key}" %>" class="<%= resource.class.name.underscore %>">
This is to translate %tr[resource].
Now, the {odd_or_even} will just convert the result hash of the helper odd_or_even to map them as attributes on the tr.
If we take a look at the definition of the method here : https://github.com/gmarik/simple-backend-example/blob/master/app/helpers/backend/application_helper.rb
We see it's just a call to cycle in order to set an extra class. Therefore we end up with:
<tr id="<%= "#{resource.class.name.underscore}_#{resource.to_key}" %>" class="<%= "#{resource.class.name.underscore} #{cycle("odd", "even", name: "rows")}" %>">
Now, all of this won't fix the problem of paginate. Add the error message if you're still stuck on this.
