Hello, I wish I had the time to figure this out but I'm on a limited timeline to convince people to look at RoR instead of Drupal, so I need to get something relatively simple working fast. Any help or pointers would be appreciated!
I have two HABTM many models, recipe_item and purchase_item. I need a form to designate in my view that any number of purchase_items or recipe_items can be a component of a given recipe_item. It looks like Ryan Bates' screencast on nested model forms provides a lot of help on a similar issue, but I'm having trouble picking apart the logic for my issue. Regardless at the moment as a test I'm just trying to get a single select on the recipe_item view to submit the purchase_item association. When I submit I get this error:
PurchaseItem(#20112400) expected, got Array(#102050)
Here is my code:
Models:
class PurchaseItem < ActiveRecord::Base has_and_belongs_to_many :recipe_items end
class RecipeItem < ActiveRecord::Base has_and_belongs_to_many :purchase_items end
Controllers are left completely as generated by 2.3 Rails scaffolding.
New recipe_item View:
<h1>New recipe_item</h1>
<% form_for(@recipe_item) do |f| %> <%= f.error_messages %>
<p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> <p> <% f.fields_for :purchase_items do |n| %> <%= n.label :purchase_item_id %> <%= n.select :purchase_item_id, PurchaseItem.all.collect {|a| [a.name, a.id] }%> <% end %> </p> <p> <%= f.submit 'Create' %> </p> <% end %>
<%= link_to 'Back', recipe_items_path %>
I'm aware this can be DRYed up but like I said right now I just need to demonstrate something working for my team. Any help would be appreciated!
Thanks, Andy
