Grails Gorm:Can'；删除后不能删除
我对戈姆有一个（对我来说很奇怪的）问题 我们必须清理我们项目中的一些数据，除了一件事情外，其他一切都很好 下面是我们的域类的摘录Grails Gorm:Can'；删除后不能删除,grails,gorm,Grails,Gorm,我对戈姆有一个（对我来说很奇怪的）问题 我们必须清理我们项目中的一些数据，除了一件事情外，其他一切都很好 下面是我们的域类的摘录 class Person { ... } class Grade { ... static hasMany = [speaker: Person] } 现在我正在搜索要删除的特定人群（重复）。找到它们后，我需要将要删除的人的所有实例切换到剩余的实例。下面是这一逻辑的摘录： def personDelete = Person.get(it.get
class Person {
...
}
class Grade {
...
static hasMany = [speaker: Person]
}
def personDelete = Person.get(it.get("bhlneuPerson"))
def personBase = Person.get(it.get("bhlPerson"))
...
def grades = Grade.withCriteria {
speaker {
eq("id", personDelete.id)
}
}
grades.each {
it.removeFromSpeaker(personDelete)
it.addToSpeaker(personBase)
it.save(failOnError: true)
}
...
people.each {
def pers = Person.get(it)
if(pers)
pers.delete()
}
