答案 0 :(得分:2)
当堆栈跟踪指出时,发生该错误是因为用户的email
字段为空。
这意味着User user= new User(params)
失败。那是因为你给出了错误的参数来初始化用户,例如,“用户类”没有“地址”属性。您应该new Employer()
代替。

GORM将nullable: false
设置为域的每个字段的默认约束。因此,当您在域中保存一行时,由于nullable:false
,您给出的错误将会解决。要解决此问题,一种方法是将nullable:true
设置为GORM的默认约束。您可以在Config.groovy
grails.gorm.default.constraints = { '*'(nullable:true, blank:true) }
当您需要为任何字段设置nullable:true
时,您将手动将其设置在域类中。
