ios - 添加关键路径不同于关系名称的 Restkit 关系映射

Question

我正在尝试将关系映射添加到我的请求映射之一。

POST 请求应该发送正文内容:

{"account":{"key":"the_key_goes_here","terms_of_service":1,"person_attributes":{"email":"test@example.com"}}}

我已将帐户映射设置为:

NSMutableDictionary *accountAttributes = [NSMutableDictionary dictionaryWithDictionary: @{@"key":@"key",@"terms_of_service":@"terms_of_service",@"source":@"source"}];
RKObjectMapping *requestMapping = [RKObjectMapping requestMapping];
[requestMapping addAttributeMappingsFromDictionary:accountAttributes];

现在，为了尝试将 person_attributes 添加到请求中，我执行以下操作:

NSMutableDictionary *userAttributes = [NSMutableDictionary dictionaryWithDictionary: @{@"first_name":@"first_name",@"last_name":@"last_name",@"email":@"email"}];
RKObjectMapping *userMapping = [RKObjectMapping requestMapping];
[userMapping addAttributeMappingsFromDictionary:userAttributes];
[requestMapping addRelationshipMappingWithSourceKeyPath:@"person" mapping:userMapping];

但是，这总是发送为:

{"account":{"key":"the_key_goes_here","terms_of_service":1,"person":{"email":"test@example.com"}}}

为了将 person 更改为 person_attributes，我将 relationshipmappingwithsourcekeypath 修改为:

[requestMapping addRelationshipMappingWithSourceKeyPath:@"person_attributes" mapping:userMapping];

但是，它每次都失败并出现错误，指出:实体帐户不符合键“person_attributes”的键值编码

我知道这是因为 Account 没有 person_attributes 值。有没有办法将 key 路径添加为 person 但将其作为 person_attributes 发送？

提前感谢您的帮助!

您需要使用 RKRelationshipMapping 类和 relationshipMappingFromKeyPath:toKeyPath:withMapping: 方法来创建关系，然后使用 addPropertyMapping: 进行设置>.
