[英]How convert Realm data to Json on Swift? Realm version 10.11.0
在 Realm 版本 10.7.6 之前,我可以使用下面的代码转换为字典,然后转换为 json,但 ListBase class 不再存在。
extension Object {
func toDictionary() -> NSDictionary {
let properties = self.objectSchema.properties.map { $0.name }
let dictionary = self.dictionaryWithValues(forKeys: properties)
let mutabledic = NSMutableDictionary()
mutabledic.setValuesForKeys(dictionary)
for prop in self.objectSchema.properties as [Property] {
// find lists
if let nestedObject = self[prop.name] as? Object {
mutabledic.setValue(nestedObject.toDictionary(), forKey: prop.name)
} else if let nestedListObject = self[prop.name] as? ListBase { /*Cannot find type 'ListBase' in scope*/
var objects = [AnyObject]()
for index in 0..<nestedListObject._rlmArray.count {
let object = nestedListObject._rlmArray[index] as! Object
objects.append(object.toDictionary())
}
mutabledic.setObject(objects, forKey: prop.name as NSCopying)
}
}
return mutabledic
}
}
let parameterDictionary = myRealmData.toDictionary()
guard let postData = try? JSONSerialization.data(withJSONObject: parameterDictionary, options: []) else {
return
}
List
现在显然继承自RLMSwiftCollectionBase
,因此您可以改为检查它。 此外,这是斯威夫特。 使用[String: Any]
而不是NSDictionary
。
extension Object {
func toDictionary() -> [String: Any] {
let properties = self.objectSchema.properties.map { $0.name }
var mutabledic = self.dictionaryWithValues(forKeys: properties)
for prop in self.objectSchema.properties as [Property] {
// find lists
if let nestedObject = self[prop.name] as? Object {
mutabledic[prop.name] = nestedObject.toDictionary()
} else if let nestedListObject = self[prop.name] as? RLMSwiftCollectionBase {
var objects = [[String: Any]]()
for index in 0..<nestedListObject._rlmCollection.count {
let object = nestedListObject._rlmCollection[index] as! Object
objects.append(object.toDictionary())
}
mutabledic[prop.name] = objects
}
}
return mutabledic
}
}
感谢@Eduardo Dos Santos。 只需执行以下步骤。 你会对 go 很好。
