我有多个选择,如下所示:
<g:select name="receiptItems" from="${HealthService.findAllByDoctor(Doctor.findBySecUser(new ReceiptController().getCurrentlyLoggedUser()))}"
multiple="multiple" optionKey="id"
optionValue="${{it.healthServiceType.healthService}}"
size="5" value="${receiptInstance?.healthServices*.id}" class="many-to-many"
onchange="${remoteFunction(
controller: 'Receipt',
action: 'sumReceiptItems',
params: '\'receiptItemsSelected=\' + jQuery(this).val()',
onSuccess: 'updateTotalAmount(\'totalAmount\', data, \'00000\')')}"/>
每次选择后,使用
remoteFunction
,将调用 Controller 中的方法进行一些计算并更新totalAmount字段。它工作正常,但是,当调用save
方法时,healthServices
字段为null ...而且我不明白为什么。我也尝试过
receiptInstance?.healthServices.collect{it.id}
但我有相同的结果。
有什么建议吗?
最佳答案
您将选择标签命名为“ receiveItems ”,因此在Controller中检查该参数,然后将其添加到receiveInstance:
params?.receiptItems?.each {
def service = HealthService.get(it)
receiptInstance.addToHealthServices(service)
}
