Cannot create form with multiple select option

Should you be using collection_select instead?

This is how I've used casein_select for one-to-one relationships before. I can't see any reason why multiple wouldn't be passed through. If you're able to share your project with me, I can take a look.

<%= casein_select f, f.object, :column, Column.order(:title).collect {|c| [c.title.titlecase, c.id]}, {:include_blank => '-- None --', :casein_label => "Choose an existing column"} %>

As for other advice: in general, you can use the form partials directly for nested attributes:

<%= f.fields_for :column do |column_form| %>
    <%= render :partial => 'casein/columns/form', :locals => { :f => column_form } %>
<% end %>

Casein's support for relationships in the scaffolding isn't great, but when not using nested attributes, I usually scaffold out the child models using the --no-index option (this stops it being added to the tabbed navigation, removes the unneeded controller methods, limits the appropriate routes, etc.) which will generate all the view partials. Then I add render the child's _index partial at the bottom of the parent's show view, plus I add a button to create a new child object into the sidebar of the parent's show view. It requires a little copying and pasting, but you can quickly build up the views.

Getting better automated support for relationships in the scaffolder would be great though — I just don't have time right now, but I'm always looking for help to expand the project ;)

Thanks so much for the help, and the quick reply! Much appreciated! I got the form to render- still working through a few things but overall everything makes sense. We all really like how straighforward/lightweight Casein is.

If we end up using Casein in our project, we'll definitely look into helping with the scaffolding for relationships :) Thanks so much for making this project open source!
