in ExtJS, is it better to call Model.save() or Store.Sync()?

extjs

Solution

automatically refreshes the Model with results from the server

`Store.sync()` refreshes modified records as well (provided you have setup the server response correctly).

So, technically, both methods do the same. However, in my opinion, you can use `Model.save()` only in one case: when you don't have `store`. Why? Because when you have store and nevertheless you use `Model.save()` that's mean that you have setup connection (proxy) configuration for both `store` and `model`. And that's mean that you have duplicated code which is potentially harder to maintain.

So, to summarize, you use `Model.save()` only if you use standalone model, without store (it may be the case when you have `form` which is not connected to any grid. So you create standalone model for such form), and you use `Store.sync()` in other cases.
