使用accepts_nested_attributes_for时忽略验证失败（即防止回滚）？

因此，假设我有 Person 和 Child 模型：

class Person < ActiveRecord::Base
    has_many :children
    accepts_nested_attributes_for :children
end

class Child < ActiveRecord::Base
    belongs_to :parent, :class_name => "Person"
    validates_presence_of :name
end

现在，当我使用嵌套表单并保存具有 2 个新子项的 Person 时，如果其中一个子项无法验证（即它将回滚），则整个事务将失败。

如何忽略此验证失败并仅保存有效的 1 个人和 1 个孩子？我不希望整个交易失败，因为 1 个孩子未通过验证。我只是想保存有效记录...

非常感谢您的帮助，谢谢！

PS 使用 :reject_if 如果不是我的选择，因为我需要能够访问无效记录，直到将其保存到数据库中（此时我想拒绝剩余的记录）无效的）

So suppose I have the Person and Child models:

class Person < ActiveRecord::Base
    has_many :children
    accepts_nested_attributes_for :children
end

class Child < ActiveRecord::Base
    belongs_to :parent, :class_name => "Person"
    validates_presence_of :name
end

Now when I use a nested form and save a Person with 2 new children, the entire transaction will fail if one of the children fails to validate (i.e. it will rollback).

How do I ignore this validation failure and just save the 1 Person and 1 child that are valid? I do not want the entire transaction to fail because 1 child failed the validation. I simply want to save the valid records...

Help much appreciated, thanks!

P.S. using :reject_if if not an option for me because I need to be able to access the invalid records up until the moment I save it into the database (at which time I want to reject the ones that remain invalid)
