一直坚持这一点,我正在使用向导 gem 并希望以嵌套形式保存租户属性。属性正在保存,但在数据库中输出 nil。似乎无法理解为什么不确定它是否是宝石,或者我在模型或控制器中遗漏了一些明显的东西。
参数
Parameters: {"utf8"=>"✓", "authenticity_token"=>"xPqiDsUpnuLHCSnU+XuAUce4b/cTnM/gv6T7wxdIz4g=", "property"=>{"tenants_attributes"=>{"0"=>{"title"=>"Mr", "firstname"=>"Foo", "surname"=>"bar", "dateofbirth(1i)"=>"2013", "dateofbirth(2i)"=>"7", "dateofbirth(3i)"=>"21", "telno"=>"01143268375", "contact_type"=>"foo", "email"=>"example@gmail.com"}}}, "commit"=>"Create Tenant", "property_id"=>"58"}
这是将租户属性显示为 nil 的日志。
INSERT INTO "tenants" ("contact_type", "created_at", "dateofbirth", "email", "firstname", "property_id", "surname", "telno", "title", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [["contact_type", nil], ["created_at", Sun, 21 Jul 2013 10:53:00 UTC +00:00], ["dateofbirth", nil], ["email", nil], ["firstname", nil], ["property_id", nil], ["surname", nil], ["telno", nil], ["title", nil], ["updated_at", Sun, 21 Jul 2013 10:53:00 UTC +00:00]]
