Query predicates do not properly support lists for observeQuery() #1229

Closed Abdelazeem777 closed 2 years ago

Abdelazeem777 commented 2 years ago

Describe the bug I am using observeQuery to get a stream for my changes on (Chat) table, every chat object contains usersInfo item which is a list of JSON.

So when any changes happen to this table I am getting this exception.

Unhandled Exception: type 'CastList<Object?, String>' is not a subtype of type 'String?' of 'other'

I think the problem is with your map casting executed with every chat item.

To Reproduce

  1. Just listen to any changes that happen to a table containing items with a list of AWSJSON using observeQuery.

  2. then you will get this exception: Unhandled Exception: type 'CastList<Object?, String>' is not a subtype of type 'String?' of 'other'

Expected behavior Should return all changed objects without any exceptions.

After Some playing with the code, I figure out the lint that caused this issue.

 @override
  Stream<Chat> observeUserChatsChanges(String userId) {
    return Amplify.DataStore.observeQuery(
      Chat.classType,
      where: Chat.USERSID.contains(userId), //<== This line is causing the issue
      sortBy: [Chat.LASTMESSAGESENDTIME.descending()],
    )
        .where((snapshot) => snapshot.items.isNotEmpty)
        .map((snapshot) => snapshot.items.first);
  }

So if I removed this line the exception will disappear but still, this is not a solution for this bug. I still need to filter my chats by userId

Hi @Abdelazeem777 Thanks for reporting this issue.

What's the data type of the field userId of the Chat model? Do you mind to paste the schema here?

Abdelazeem777 commented 2 years ago

@HuiSF usersId is a list of String (ID).

My guess is that the .contains() query predicate isn't properly handling lists for observeQuery. I can test this theory out.

Related - If we address issue https://github.com/aws-amplify/amplify-flutter/issues/840, that would help identify these issues with proper typing.

Jordan-Nelson commented 2 years ago

I was able to reproduce this in the DataStore example app with the following code.

// set up subscription
Amplify.DataStore.observeQuery(
  StringListTypeModel.classType,
  where: StringListTypeModel.VALUE.contains('123'),
).listen((QuerySnapshot<StringListTypeModel> snapshot) {
  setState(() {
    print(snapshot.items.length);
  });
});

// add button inside build method
ElevatedButton(
  onPressed: () async {
    await Amplify.DataStore.save(
      StringListTypeModel(value: ['123', 'abc']),
    );
  },
  child: Text('Create String List'),
),

@Abdelazeem777 - I am looking into a fix for this. In the meantime, below is a workaround. If you choose to use this workaround, I would advise testing it thoroughly for your use cases and keeping an eye out for a more permanent fix.

Work Around

Chat.USERSID is of type QueryField. The .contains() method on the QueryField class isn't properly handling lists. This workaround adds a new method, .listContains(), which does properly handle lists. Note: If you try to use .listContains() on a field that isn't a list, it will throw an exception.

  1. Add the following extension to your app, and import it where you would like to use .listContains(). 
    
extension ListQueryField on QueryField<dynamic> {
QueryPredicateOperation listContains(dynamic value) =>
  QueryPredicateOperation(
    this.fieldName,
    ListContainsQueryOperator(value),
  );
}

class ListContainsQueryOperator extends QueryFieldOperator<List> { final dynamic value;

const ListContainsQueryOperator(this.value) : super(QueryFieldOperatorType.contains);

@override bool evaluate(List? other) { if (other == null) { return false; } return other.contains(value); }

@override Map<String, dynamic> serializeAsMap() { return serializeAsMapWithOperator( QueryFieldOperatorType.contains.toShortString(), value, ); } }


2. Update the code snippet you had shared to use the new method.
```dart
 @override
  Stream<Chat> observeUserChatsChanges(String userId) {
    return Amplify.DataStore.observeQuery(
      Chat.classType,
      where: Chat.USERSID.listContains(userId), // <== UPDATED
      sortBy: [Chat.LASTMESSAGESENDTIME.descending()],
    )
        .where((snapshot) => snapshot.items.isNotEmpty)
        .map((snapshot) => snapshot.items.first);
  }

Support for lists has been release in version 0.5.0. The .contains() query predicate now supports Lists.
