accepts_nested_attributes_for

Hello,

I'm using accepts_nested_attributes_for for my project.

Models

   Course:              belongs_to :user              has_many :holes              has_many :scores              accepts_nested_attributes_for :holes

  Hole :             belongs_to :user             belongs_to :course             has_many :beacons             accepts_nested_attributes_for :beacons

Beacon:

     belongs_to :user            belongs_to :course            belongs_to :hole

  def course_params           params.require(:course).permit(:name, :street, :city, :state, :zip, :course_role,                                        :latitude, :longitude, :course_image, :phone_number,                                        :restaurant_phone_number, :restaurant_menu_file,                                        :welcome_message, :fromtheproshop_message, :user_id,                                        :fromtheclubhouse_message, :aroundtheclub_message,

                              :holes_attributes => [:id, :name, :hole_image, :user_id,

                             :beacons_attributes => [:id, :name,:user_id,                                                      :caddy_tip, :smartest_play, :be_aware]                                                     ])     end

each Course contains 18 holes and each hole have 3 beacons,I need to edit all in single page shown in image(Ox_alt(1).jpg).In that image if we assume user clicked on hole-9 then display hole-9's 3 beacons and edit and submit then after user may want to edit hole 15 or any, then i need to display that user clicked hole beacons. I've completed with static hole-id in my logic. But I.m struck in get user clicked hole beacons dynamically.

views/course/edit.html logic is:

<%= form_for (@course), remote: true do |cb| %> <div class="course-name1"> <%= cb.text_field :name, class: "form-control" %></div> <div id="tabs"> <ul> <% (cb.object.holes).each do |i| %> <div class="hole-one"> <li><h3 class="hole-one-one"><a href="#<%= i.id %>-hole" id="hole-<%= i.id %>" class="hole" ><%= i.id %></a></h3> <div class="circular circle-green circle-left"></div> </li> </div> <% end %> </ul> </div>

<%= cb.fields_for :holes do |hb| %> <% if hb.object.id == 19 %> #here give hole-id =19 without this i'll get all beacons i.e 18*3 edit page <h3> <%= hb.object.name %></h3> <%= hb.fields_for :beacons do |bb| %> <% if hb.object.id == 19 %> <div class="caddy-tip-label"> <%= bb.label :CaddyTip, class: "from-shop2" %></div> <div class="caddy-tip-textarea"> <%= bb.text_area :caddy_tip, class: "form-control from-shop4", id:"textarea" %></div> <% end %> <% end %> <% end %> <% end %> <% end %>
