Hi guys.
When I subscribe object by LiveQuery, data can not be decoded to PHObject, code:
import Foundation
import ParseCore
import ParseLiveQuery
classSuggestion:PFObject,PFSubclassing{@NSManagedvartitle:String?@NSManagedvardocument:Document?classfunc parseClassName()->String{return"Suggestion"}}classSuggestions{letsubscribe:Subscription<Suggestion>init(){ParseLiveQuery.Client.shared.shouldPrintWebSocketTrace =true
subscribe =ParseLiveQuery.Client.shared.subscribe(Suggestion.query()!.includeAll()as!PFQuery<Suggestion>).handleEvent{
log.I("recive \($1)") // never logging
}}}
Reiceived Json on WebSocket callback:
{
"op":"delete",
"clientId":"d81000da-4f64-4819-a470-8aade320322a",
"requestId":2,
"object":{
// I think should have a "__type": "Object" here"document":{
"__type":"Pointer",
"className":"Document",
"objectId":"EtZCPMTygF"
},
"title":"Suggestion 20",
"createdAt":"2024-01-18T13:41:59.930Z",
"updatedAt":"2024-01-18T13:41:59.930Z",
"className":"Suggestion",
"objectId":"aN94A8fXYB"
}
}
I checked the code in PHDecoder and found that because of no "__type": "Object" in "object", it can not be decoded to PHObject or its subclass.
PHDecoder snippet(line 43):
- (id)decodeDictionary:(NSDictionary *)dictionary {
NSString *op = dictionary[@"__op"];
if (op) {
return [[PFFieldOperationDecoder defaultDecoder] decode:dictionary withDecoder:self];
}
NSString *type = dictionary[@"__type"];
if (type) {
if ([type isEqualToString:@"Date"]) {
return [[PFDateFormatter sharedFormatter] dateFromString:dictionary[@"iso"]];
} elseif ([type isEqualToString:@"Bytes"]) {
return [PFBase64Encoder dataFromBase64String:dictionary[@"base64"]];
} elseif ([type isEqualToString:@"GeoPoint"]) {
return [PFGeoPoint geoPointWithDictionary:dictionary];
} elseif ([type isEqualToString:@"Polygon"]) {
return [PFPolygon polygonWithDictionary:dictionary];
} elseif ([type isEqualToString:@"Relation"]) {
return [PFRelation relationFromDictionary:dictionary withDecoder:self];
} elseif ([type isEqualToString:@"File"]) {
return [PFFileObject fileObjectWithName:dictionary[@"name"]
url:dictionary[@"url"]];
} elseif ([type isEqualToString:@"Pointer"]) {
NSString *objectId = dictionary[@"objectId"];
NSString *localId = dictionary[@"localId"];
NSString *className = dictionary[@"className"];
if (localId) {
// This is a PFObject deserialized off the local disk, which has a localId// that will need to be resolved before the object can be sent over the network.// Its localId should be known to PFObjectLocalIdStore.return [self_decodePointerForClassName:className localId:localId];
} else {
return [self_decodePointerForClassName:className objectId:objectId];
}
} elseif ([type isEqualToString:@"Object"]) {
// 🟨🟨🟨🟨🟨🟨🟨🟨// Should go here, but no "__type": "Object" in "object", so it can not be decoded to PHObject or its subclass.// 🟨🟨🟨🟨🟨🟨🟨🟨NSString *className = dictionary[@"className"];
NSMutableDictionary *data = [dictionary mutableCopy];
[data removeObjectForKey:@"__type"];
[data removeObjectForKey:@"className"];
NSDictionary *result = [selfdecodeDictionary:data];
return [PFObject _objectFromDictionary:result
defaultClassName:className
completeData:YESdecoder:self];
} else {
// We don't know how to decode this, so just leave it as a dictionary.return dictionary;
}
}
NSMutableDictionary *newDictionary = [NSMutableDictionarydictionaryWithCapacity:dictionary.count];
[dictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
newDictionary[key] = [selfdecodeObject:obj];
}];
return newDictionary;
}
And I added some workaround code to ParseLiveQuery/ParseLiveQuery/Internal/ClientPrivate.swift, everything is working fine. here is the code:
