将枚举列表传递给条件
我有一个域 Payment
class Payment {
String name
PaymentType paymentType
}
PaymentType is an ENUM
来搜索特定付款类型的所有付款，这很简单，
def results = Payment.createCriteria.list = {
'in' ('paymentType', PaymentType.valueOf(params.paymentType))
}
当我想针对多种付款类型搜索所有付款时，我该如何处理这种情况，即如果参数。 paymentType 是一个数组吗？
I have a domain Payment
class Payment {
String name
PaymentType paymentType
}
PaymentType is an ENUM
to search all payments of a particular payment type is simple
def results = Payment.createCriteria.list = {
'in' ('paymentType', PaymentType.valueOf(params.paymentType))
}
how can i handle the situation when I want to search all Payments against more then one payment type i.e. if params.paymentType is an array?

如果 paymentType 是一个数组，你可以这样做：
If paymentType is an array, you can do something like this:
@ataylor：
我不太确定..但不应该是
def results = Payment.createCriteria().list {'in' (' paymentType',new params. paymentType.collect{PaymentType.valueOf(it)})
}
否则你会得到一个错误
groovy.lang.MissingPropertyException: No such property: params for class: grails.orm.HibernateCriteriaBuilder@ataylor:
I am not really sure.. but shouldnt it be
def results = Payment.createCriteria().list {'in' ('paymentType',new params.paymentType.collect{PaymentType.valueOf(it)})
}
or you'll be getting an error
groovy.lang.MissingPropertyException: No such property: params for class: grails.orm.HibernateCriteriaBuilder
