ruby-on-rails - Rails admin以has_many嵌套形式隐藏hide_to字段

Question

我有两个模型

class Entity < ActiveRecord::Base
  # Associations
  has_many :contacts
  accepts_nested_attributes_for :contacts, :allow_destroy => true
end

class Contact < ActiveRecord::Base
  # Associations
  belongs_to :entity
end

现在在rails admin中，我得到以下选项。

添加新的联系表



添加新的实体表单

我需要在添加新实体的同时在联系表单中隐藏实体字段。

任何帮助将是有用的。

您可以像这样使用inverse_of自动隐藏字段

class Entity < ActiveRecord::Base
  # Associations
  has_many :contacts, inverse_of: :entity
  accepts_nested_attributes_for :contacts, allow_destroy: true
end

class Contact < ActiveRecord::Base
  # Associations
  belongs_to :entity, inverse_of: :contacts
end

If you set the :inverse_of option on your relations, RailsAdmin will automatically populate the inverse relationship in the modal creation window. (link next to :belongs_to and :has_many multi-select widgets)
