问题描述
在 Doctor 类中，我有RealmList- specializationList .
Inside Doctor class, I have RealmList - specializationList.
public class Doctor extends RealmObject {
@PrimaryKey
private String doctorId;
private FullName fullName;
private Age age;
private String organizationId;
private Position position;
private String category;
private String loyalty;
private RealmList<Specialization> specializationList;
private Contacts contacts;
private String key;
....
专业化类
public class Specialization extends RealmObject{
private String specializationName;
...
医生JSON:
[
{
"doctorId": "7d8e72d7-809b-4273-9a3f-fa21718dee7f",
"doctorFullName": {
"firstName": "FirstName0",
"lastName": "LastName0",
"middleName": "MiddleName0"
},
"doctorPosition": {
"positionName": "PositionName0",
"department": "Department0"
},
"organizationId": "7cfaf5c0-127a-4cfc-b73b-52a35fd02ffd",
"specializations": [
{
"specializationName": "Specialization name 3"
},
{
"specializationName": "Specialization name 2"
},
{
"specializationName": "Specialization name 1"
}
],
"key": "firstname0 middlename0 lastname0"
}
]
使用 createOrUpdateAllFromJson 方法解析JSON:
Parsing JSON using createOrUpdateAllFromJson method:
realm.createOrUpdateAllFromJson(Doctor.class, json);
我想做的是从医生对象获取RealmList:
What I am trying to do is getting RealmList from doctor object:
RealmList<Specialization> specializationList = doctor.getSpecializationList();
但是specializationList的大小为0.
But specializationList's size is 0.
领域文档:某些JSON API会返回Real尚不支持的原始类型的数组，例如整数或字符串.
Realm documentation:Some JSON APIs will return arrays of primitive types like integers or Strings, which Realm doesn’t support yet.
可以使用createOrUpdateAllFromJson解析JSON数组(专业化)吗?
Can JSON array(specializations) be parsed using createOrUpdateAllFromJson?
推荐答案
是的，Realm应该可以解析它，但是看起来您的命名不正确. Doctor类将其称为specializationList，但在JSON中为specializations.
Yes, Realm should be able to parse that, but it looks like your naming is not right. Your Doctor class calls it specializationList but in your JSON it is specializations.
如果您将Doctor类更改为以下类别，则应该可以使用:
If you change your Doctor class to the following it should work:
public class Doctor extends RealmObject {
@PrimaryKey
private String doctorId;
private FullName fullName;
private Age age;
private String organizationId;
private Position position;
private String category;
private String loyalty;
private RealmList<Specialization> specializations;
private Contacts contacts;
private String key;
....
