[英]Grails. Domain class. Json string problem
i have this domain class: 我有这个领域类:
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 = {
}
}
I need to create a string JSON, which contains only information about these fields: 我需要创建一个字符串JSON,它只包含有关这些字段的信息:
String office;
String branch;
String name;
Integer code;
Integer number;
Integer term;
Integer amount;
Integer rate;
I try: 我尝试:
rezult = Credit.list(fetch:[debts:"lazy", fronts: 'lazy', securities: "lazy", lawyers:"lazy", quarantes:"lazy"])
render new JSON(success: true, message: 'ok', data:rezult);
but in JSON string i have all data :( debts, fronts, securities... inside string too. but i not need this data. 但是在JSON字符串中我拥有所有数据:(债务,前额,证券...也在字符串内。但是我不需要此数据。
How I do avoid using them? 如何避免使用它们?
ANSWER: 回答:
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
}
}
}
you are going to have to use the json builder to solve this problem 您将必须使用json构建器来解决此问题
You could try and set setRenderDomainClassRelations
on JSON
to false but I suppose what you really need is to use a builder and explicitly declare the JSON structure further: 您可以尝试将
JSON
上的setRenderDomainClassRelations
设置为false,但我想您真正需要的是使用构建器并进一步明确声明JSON结构:
render(builder:'json') {
success(true)
message('ok')
data {
office(rezult.office)
branch(rezult.branch)
// and so on
}
}
}
