在bootstrap中，让初始化的时候向表中插入数据，结果category表中可以插入数据，goods表中总是失败，这是为什么呢？
下面是表对应的domain
package my


class Goods {


String title
String description
BigDecimal price
String photoUrl
Category category
}



package my


class Category {


String categoryName
static hasMany = [goods:Goods]
static constraints = {
categoryName(unique:true)
}
}
