我有這個領域類:Grails。領域類。 JSON字符串問題
package test
class Credit {
String office;
String branch;
String name;
Integer code;
Integer number;
Integer term;
Integer amount;
Integer rate;
static hasMany = [ debts : Debt,
fronts : Front,
securities : Security,
lawyers : Lawyer,
guarantes : Guarante]
static constraints = {
}
}
我需要創建一個字符串,JSON,其中包含有關這些領域的唯一信息:
String office;
String branch;
String name;
Integer code;
Integer number;
Integer term;
Integer amount;
Integer rate;
我嘗試:
rezult = Credit.list(fetch:[debts:"lazy", fronts: 'lazy', securities: "lazy", lawyers:"lazy", quarantes:"lazy"])
render new JSON(success: true, message: 'ok', data:rezult);
但JSON字符串我有所有數據:(債務,前線,證券......內部字符串也是如此。 但我不需要這些數據。
我如何避免使用它們?
答:
render(contentType:"text/json") {
success=true
message='ok'
totalCount=Credit.count()
data = array {
for(d in results) {
data office:d.office,
branch:d.branch,
name: d.name,
code:d.code,
number:d.number,
term:d.term,
amount:d.amount,
rate:d.rate
}
}
}
