Question

我已经在StackOverflow和Google上详尽地查找了这个，但没有找到答案来帮助我，所以我问这个，虽然我知道这个主题在这里几乎没有讨论过。

我在比赛和主题之间有HABTM关系，我的日志显示了在发布新比赛或编辑现有比赛时的ID数组，但它根本没有在我的postgres数据库中记录任何内容。

我正在使用ActiveAdmin 1.0和Rails 4

下面是我的代码：

class Contest < ActiveRecord::Base
    attr_accessor :subjects_ids

    has_and_belongs_to_many :subjects
    belongs_to :examination_board 
    belongs_to :bureau
    belongs_to :role
    belongs_to :degree
    belongs_to :career
end

class Subject < ActiveRecord::Base
    attr_accessor :contests_ids

    has_many :questions
    has_and_belongs_to_many :contests
end

ActiveAdmin.register Contest do

  permit_params :name,
                :year,
                :state,
                :city,
                :examination_board_id,
                :role_id,
                :degree_id,
                :career_id,
                :bureau_id,
                subjects_ids: [:id]

  # scope :states

  index do
    column "Nome", :name
    column "Banca Examinadora", :examination_board
    column "Matérias" do |subject|
      div :class => 'subjects' do
        subjects = ['yo','la','ho'].join(', ')
      end
    end
    actions
  end

  form do |f|
    f.semantic_errors 
    f.inputs          
    f.input :subjects, as: :check_boxes, collection: Subject.all
    f.actions         
  end

end

我感谢任何建议，谢谢大家！

Answer 1

嗯，事实证明我距离它不远。我唯一的问题是这一行：

subjects_ids：[：id]

我不应该把那个＆＃34;：id＆＃34;加上正确的名称是＆＃34; subject_ids＆＃34;。

就是这样，它现在就像一个魅力。
