Rails 4.0.3 Active-Admin has_many 复选框未保存

Question

我使用 rails 4.0.3 并尝试在 Active-Admin 中设置多对多的复选框。未保存复选框选择。这就是我所拥有的

class Product < ActiveRecord::Base
  has_many :categorizations
  has_many :categories, :through => :categorizations
  accepts_nested_attributes_for :categorizations
end

class Category < ActiveRecord::Base
  has_many :categorizations
  has_many :products, :through => :categorizations
  accepts_nested_attributes_for :categorizations
end

class Categorization < ActiveRecord::Base
  belongs_to :category
  belongs_to :product
end

ActiveAdmin.register Product do

  permit_params :title, :price, category_ids:[:id]

  form do |f|
    f.semantic_errors *f.object.errors.keys
    f.inputs "Product" do
      f.input :title
      f.input :price
      f.input :categories, :as => :check_boxes
    end
    f.actions
  end
end

我也尝试过使用 has_and_belongs_to_many 但仍然无法保存选择。

任何指导将不胜感激。

干杯

尝试添加

permit_params :title, :price, category_ids:[:id], categories_attributes: [:id, :your_fields, :_update,:_create]

Answer 2

我发现将以下内容添加到您的 active_admin 文件 product.rb 可以修复它。

ActiveAdmin.register Product do
  permit_params category_ids: []
end
