[英]Save list in mongodb using grails
im new to mongodb so a little confused on how do i save the list object in mongodb using grails, basically i have a list of hasmap , which is in turn is a string,list map , like this 我是mongodb的新手,所以我对如何使用grails在mongodb中保存列表对象有些困惑,基本上我有一个hasmap列表,而hasmap列表又是一个字符串,列表映射,像这样
List<HashMap<String, ArrayList<Object>>> changedProperties = new ArrayList<HashMap<String, ArrayList<Object>>>()
and here is my domain class that have this type of property 这是我的具有此类属性的域类
class DatabaseEvent {
String type
String entityClass
String objectId
Date dateCreated
User loggedInUser
List<HashMap<String, ArrayList<Object>>> changedProperties
}
if i simply pass this type of list , it is not saving. 如果我只是通过这种类型的列表,则无法保存。
[[description:[null, some test]], [name:[Testing 12, Testing 1]], [displayOrder:[4, 11]]]
im passing the above list , but it rejects with this error 我通过上面的列表,但它拒绝此错误
rejected value [[{description=[null, some test]}, {name=[Testing 12, Testing 1]}, {displayOrder=[4, 11]}]]
