Hi, I''m currently stuck with a problem I just can''t find a clever solution for. I checked every tutorial, issuetracker, API reference I could find but found nothing to "enlighten" me --> I desperately need your help :-). My Question is: is it possible to use nested forms for habtm associations? --> Here some more info about what I wanted to do and what failed ### Basic info ### I''ve got following model associations: Customer has_many :inquiries attr_accessible :inquiry_ids accepts_nested_attributes_for :inquiries Inquiry belongs_to :customer has_and_belongs_to_many :machines accepts_nested_attributes_for :machines attr_accessible :machine_ids Machine has_and_belongs_to_many :inquiries I''m on Rails 2.3.5 and formtastic 0.9.7 ### What I want ### I wanted to build a nested form (using formtastic + haml), so a User could enter his data and create an inquiry regarding several machines (he put into a cart in advance) so I set up this: - semantic_form_for @customer do |form| - form.inputs do = form.input :companyname = form.input :salutation, :as => :radio, :label => "Gender", :collection => [["Mister", "m"], ["Mrs.", "f"]] = form.input :first_name = form.input :last_name = form.input :street = form.input :zip = form.input :city = form.input :phone = form.input :mobile = form.input :fax = form.input :email - form.inputs :for => [:inquiries, @inquiries] do |inquiry_form| = inquiry_form.input :text, :hint => t("inquiryinfo") - inquiry_form.inputs :for => [:machines, @machines] do |machine_form| = machine_form.input :id, :as => :hidden = form.commit_button :label => t("send") ### PROBLEM ### - the form renders fine for the customer and inquiry fields --> OK! - the form renders the hidden field only for the FIRST machine in my @machines collection (and there is definitly more then 1 machine in the collection, I already checked this with array size and by outputting the machines in a for each loop) ### QUESTION ### - Did I miss some configuration? - are nested forms not usable for habtm associations??? --> if so, how could I handle my "use case" in the controller? I''d be sooo happy I any of you could help me out with this.....I''m really lost :-( P.S.
