我跟随模特:
class CapstoneMilestone < ActiveRecord::Base
attr_accessible :capstone_id, :milestone_id, :rank, :id, :status, :statusweight, :rating, :ratingweight
belongs_to :milestone
belongs_to :capstone
accepts_nested_attributes_for :capstone, :allow_destroy => false
accepts_nested_attributes_for :milestone, :allow_destroy => false
end
class Milestone < ActiveRecord::Base
has_many :capstone_milestones
has_many :capstones, :through => :capstone_milestones
attr_accessible :id, :name, :description, :department_id, :project
accepts_nested_attributes_for :capstone_milestones, :allow_destroy => true
end
我也有一个formtastic形式:
<% semantic_form_for(@capstone_milestone) do |form| %>
<%= form.semantic_errors :state %>
<% form.inputs do %>
<%= form.input :capstone_id , :as => :select, :collection => Capstone.all %>
<%= form.input :milestone_id, …
