How to update existing record in localstorage store

[kostysh]

Hi,
I have problem with updating of existing record in localstorage store.
Adding a new records with:


store.add(newRecord);

store.sync();


- no problem.
But if I try update already created record:


var record = store.findRecord('id', createdId);

record.set(updatedRecord); //updatedRecord is key-value object with new record


- error:
Uncaught TypeError: Cannot call method 'update' of undefined (in PR3 ST2)
and
Uncaught TypeError: Cannot read property 'isModel' of undefined (in PR2 ST2)

Where it may be my mistake?

local storage has been a little broken. This will get fixed before way before GA

[kostysh]

hmm.. it is a pity
perhaps there is a patch to fix the problem until the next release?

Is there any other way to locally store data at the moment? I'm really in need of this :-?

You'd have to implement your own version of it, which wouldn't be too difficult.

I see there is no activity in this thread since December. Any updates on this?

[kostysh]

All works fine for now

Perhaps I didn't explain myself correctly. Is there a way to update the localStorage records? Something along the lines of:

record.update({fieldkey:fieldval, ...})?

I know you can use record.setData({...}), but what if you have a record with several fields, and you are interested in updating only a few of those fields?

Thank you in advance.

storeObj.add({field: 'value'});
storeObj.sync();// Or setup autoSync: true in store config

Correct me if I'm wrong, but your code snippet adds a new record to the store. It does not update an existing record.

[kostysh]

Yes, you right.


Code below shows howto update record in store:


var record = storeObj.getAt(0);// Or use findRecord
record.set({field: 'value'});
storeObj.sync();

Thanks..

This is what I mean.

Suppose at one point I did something like this:
myStore.add({field1: 'val1', field2: 'val2', ..., fieldn: 'valn' });
And I needed to update one of the fields in that record, but leave the rest of the fields intact. I'd like to be able to do something along the lines of:


var rec = myStore.getById(myRecId);
rec.update({fieldx: 'valuex'})
myStore.sync();


I guess what I'm looking for doesn't exists. But it'd be a great feature to have.
