這裏是(簡化)代碼:reject_if選項被忽略
class Biosimilar::AdverseEvent < ActiveRecord::Base
attr_accessibile :adverse_event_med_conds_attributes
has_many :adverse_event_med_conds,
:class_name => 'Biosimilar::AdverseEventMedCond',
:dependent => :destroy
has_many :med_conds,
:class_name => 'Biosimilar::MedCond',
:through => :adverse_event_med_conds
accepts_nested_attributes_for :adverse_event_med_conds,
:allow_destroy => true,
:reject_if => proc { |attributes| attributes.any? {|k,v| v.blank?} }
end
當提交表單時,該記錄上,即使用戶離開「med_cond_id」字段爲空「adverse_event_med_conds」表中創建。 reject_if不起作用!
有什麼建議嗎?
如果您明確檢查該屬性會發生什麼?例如。 '':reject_if => proc {| attributes |屬性[ 'med_cond_id']。空白? }'' – GSP
