[英]How to nullify the fields that fail validation and save the domain?
Suppose there is a domain as defined below.假设有一个定义如下的域。
class Book {
String title
Author author
}
Now, i save an instance of this domain.现在,我保存了这个域的一个实例。 The author domain has some constraints.
作者域有一些限制。 So, during save the validation for author fails now instead of not saving the whole domain i want to nullify the author(The author can be null) and save the title string as it was.
因此,在保存作者验证期间现在失败而不是不保存整个域,我想取消作者(作者可以为空)并按原样保存标题字符串。 In other words how do i nullify any number of fields whose validation failed and save rest of the properties values?
换句话说,我如何取消验证失败的任意数量的字段并保存其余的属性值? Is there a convenient way to do so?
有没有方便的方法呢? Thanks!
谢谢!
This could be one of following :这可能是以下之一:
In beforeInsert hook
do something like below:在
beforeInsert hook
执行如下操作:
def beforeInsert() { this.validate() if(this.hasErrors()){ // get all errors and iterate through it and set the field to null for same } }
While saving the domain you could use在保存您可以使用的域时
domain.save(validate:false)
domain.save(验证:假)
Thanks!!谢谢!!
