I've looked at the complex_form example app on GitHub, but I'm not sure I understand how it works.
For now I've managed to display the partial using the render command, and stopped at the "add new item" link... Here's the current code:
<%= f.error_messages %>
<p> <%= f.label :name %><br /> <%= f.text_field :name %> </p>
<table id="recipe_ingredients"> <tr> <th>ingredient</th> <th>in units</th> <th>quantity</th> <th>delete?</th> </tr> <% f.fields_for :recipe_ingredients do |ri_f| %> <%= render :partial => 'recipe_ingredient', :locals => { :f => ri_f } %> <% end %> </table> <p> <%# Add new item link here... %> </p>
<p> <%= f.label :preparation %><br /> <%= f.text_area :preparation %> </p>
What I'm not clear about in the example app at GitHub[1] is where the link for creating the new item appears in the template code. (Unfortunately, I wasn't able to get the project up on my box, so I don't even know how the templates are rendered.)
If someone could explain (even if only in short) what is going on with the app, or maybe point me to a simpler solution/example, I'd appreciate it.
