findAll Resolving before it is done Updating

[eneuhauser]

I'm using ember-data 1.13.4 with the JSONAPISerializer/Adapter. I'm trying this.get('store').findAll('foo').sortBy('bar'), but it's returning an empty array. The findAll is resolving before the array is populated and the sortBy is creating a new array from the incomplete record array.

Upon inspection of this.get('store').findAll('foo').then(function(arrayProxy) {}), the arrayProxy is marked isUpdating === true. If I wait for it to be done updating, I can then apply my sort, but the original sortBy should work.

Edit:

In my adapter, I have shouldReloadAll return false, but this still happens when returning true and when calling findAll('foo', { reload: true }).

Additionally, I also want to have shouldBackgroundReloadAll return false, but when false, the initial network request is never made. If I change the logic to the following:

shouldBackgroundReloadAll: function(store, recordArray) {
  return recordArray.length === 0;
}

The network request is made the first time, but subsequent times do not clear the isUpdating flag. Instead of checking for isUpdating false, I have to check that the length is greater than 0. When set to true, the network request is made every time.

Try passing { reload: true } as the second parameter.. I had the same issue as you (array returned 0 items but isUpdating = true) and adding this second parameter fixed it for me.

Thanks @jmurphyau, but that didn't work for me. Also, I'd rather not do a reload. I have some volatile bits of information, but I'm also loading up lists of items that don't change very often, so I would like to reduce the network chattiness.

It seems it doesn't work for me either, I am loading the foo collection by running this.store.findAll('foo') and then trying this.store.findAll('foo').toArray() and it returns an empty array as well. Maybe I just don't get how to use it to get the data quickly the 2nd time, any help?

I also experienced this issue with Ember Data v1.13.5 when doing a findAll('some-model') call and { reload: true } fixed it.

@jmurphyau - What's the logic/reason that makes this the solution (or at least workaround).

[sir-dunxalot]

FYI, the adapter I am using is Emberfire's FirebaseAdapter.

I'm also experiencing this when doing (from a route):

this.get('store').findAll('model').then(function(collection) {collection.toArray()});

Anything that calls toArray appears to only return a subset of records. You can even do get('length') to see how few it may return (7 out of 46, in my case).

However, if you check it "later" using something like setTimeout after 1 second, the length is correct.

Update: using {reload: true} worked for me.

I am closing this issue since the documentation should have improved now that #4338 has been merged. Please feel free to reopen if you think this is still not documented sufficiently. Thanks!
