[英]grails command object and fields with prefixes
Im using grails 1.3.7 and here is the case... 我正在使用grails 1.3.7,情况就是这样...
Have a huge form with a few different prefixes for its fields (later used in data binding) and trying to validate thru a
command object ... however the lovely DOT used in prefixes is giving me a hard time and cannot get the names mapped properly in command object... any suggestion please?
具有巨大的形式,其字段带有几个不同的前缀 (后来用于数据绑定),并试图通过
命令对象进行验证...但是,前缀中使用的可爱的DOT给我带来了麻烦,并且无法正确映射名称在命令对象中...有什么建议吗?
in the form have fields like field like this one: 表单中的字段像这样的字段:
<input name="dealer.name" value="${dealer.name}" type="text">
and for command object: 对于命令对象:
class somethingCommand {
String name
Map dealer = [:]
static constraints = {
dealer validator: {
val, obj ->
obj.properties["name"] != ""
}
}
}
what if.... we look at it in another way and map the parameters before passing to command object... how should I pass my parameters to a command object without using grails magic?!?!?! 如果...。我们以另一种方式看待它并在传递给命令对象之前映射参数...我应该如何在不使用grails magic的情况下将参数传递给命令对象?!?!?!
tnx n
Databinding properties with prefixes to command objects is supported: 支持带有命令对象前缀的数据绑定属性:
For the command: 对于命令:
class DealerCommand {
String name
Map dealer = [:]
}
Properties named 'name', 'dealer', 'dealer.name' and 'dealer.dealer' will be bound correctly to the command object. 名为“ name”,“ dealer”,“ dealer.name”和“ dealer.dealer”的属性将正确绑定到命令对象。

you could grab the "dealer" map in the controller via 您可以通过以下方式在控制器中获取“经销商”地图
def dealerMap = params["dealer"]
and then create a dealer command opject by hand and bind the map content to it. 然后手动创建经销商命令,将地图内容绑定到该命令。
def dealerCommand = new DealerCommand()
bindData(dealerCommand , dealerMap)
you can then use the validation of the command object as normal 然后您可以像平常一样使用命令对象的验证
