Using Queries w/ syncState wipes out everything not queried

[taykcrane]

Hey Tyler,

Ran into an issue with re-base I can't seem to overcome. I have an array in state called "concerns", and when I sync it with firebase using the below code, and then make any Write operation, it wipes out everything not synced, i.e. anything that wasn't in my query.

componentWillMount = () => {
    base.syncState("concerns", {
      context: this,
      state: "concerns",
      asArray: true,
      queries: {
        orderByChild: "userId",
        equalTo: this.props.user.uid,
      },
    });
};

In your documentation under "Using Firebase Queries", your example uses syncState and limits by a query. I don't understand how this works if, after syncing, firebase deletes all the unsynced queries. Seems to make the feature entirely useless. I hope I'm missing an easy fix here, can you please help?

"re-base": "^3.2.1",
"react": "^16.0.0",
"react-dom": "^16.0.0",

@taykcrane Thanks for reporting this. I think that might be a bug in syncState because I believe in previous versions of the re-base that did work. I am not 100% sure but will check the tests to make sure that was covered at some point and figure out what happened. Sorry about that. Until I can sort that out, I would recommend using bindToState or listenTo for reading and then have separate methods for writes (using push, update, or remove as needed) over syncState when dealing with lists/collections.

@qwales1 damn, I was hoping I missed something simple. I love the simplicity of syncState, so instead of separate methods for reading/writing, I may hold out and see if you indeed find a bug in syncState. Appreciate you looking into this so quickly. LMK if you need any more code from me.

Did you find a way ? I have a similar problem, i have this architecture

• tweet
  • 0
    • user
      • screen_name: 'maxisix'

this.ref = base.syncState(tweet, {
context: this,
state: "tweet",
queries: {
orderByChild: "user",
orderByChild: "screen_name",
equalTo: "maxisix"
}
});

@maxisix I did not find a way. Any updates @qwales1?

I solved this problem by making users my top-level node, syncing the whole node, and abandoning queries entirely. Couldn't get it to work.
