Nested form error in Rails app

Models relevant to this question: user, friend, interest, person_interest. Person_interest is polymoprhic and can store interests that either belong to a user or a friend.

Interests is pre-populated with approx. 30 interests. When a user registers they are asked to select their own interests, then lower in the form enter in their friends names select the interests of that person.

Trying to achieve this with <%= friend_f.input :interests, :as => :check_boxes, :label => false %>

but getting the following error:

NoMethodError in User_steps#show

Showing /Users/nelsonkeating/Desktop/ReminDeal/app/views/user_steps/show.html.erb where line #30 raised:

undefined method `to_i' for []:ActiveRecord::Relation

Do you have any reasons to avoid friend_f.association ?

<%= friend_f.association :interests, :as => :check_boxes, :label => false %>

Works for me. Or change :interests to :interest_ids in kasper's code, also should work.

<%= friend_f.input :interest_ids, :as => :check_boxes, :label => false, :collection => Interest.all %>

Try to write code <%= friend_f.input :interests, :as => :check_boxes, :label => false %> with :collection key. For example:

<%= friend_f.input :interests, :as => :check_boxes, :label => false, :collection => Interest.all %>
