  accepts_nested_attributes_for :job_invoice_items
end

In the view

<%= form_for @job_invoice do |f| %>
  ....
    <%= f.fields_for :job_invoice_items do |builder| %>
      <tr>
        <td class="line_no">1</td>
        <td><%= builder.text_field :description %></td>
        <td class="qty"><%= builder.text_field :quantity %></td>
        <td class="unit_price"><%= builder.text_field :unit_price %></td>
        <td class="line_price"></td>
      </tr>
    <% end %>
<% end %>

On submit:

Parameters: {"utf8"=>"✓", "authenticity_token"=>"lCj6XbLdj0XO0LPR6Cy+LLixjuri9nMbh6+/DB7Wpr4=", "job_no"=>"WWH11", "job_invoice"=>{"notes"=>"test", "job_invoice_items_attributes"=>{"0"=>{"description"=>"felix 23", "quantity"=>"3", "unit_price"=>"0.0", "id"=>"1"}}}, "commit"=>"Save changes", "id"=>"2892511"}

Thoughts:
- When there is no job_invoice_items -> f.fields_for doesn't render anything.. -> must be a way
- How to make it to render 10 empty rows?
