Get new records from the store

[josepjaume]

I guess I'm doing something wrong, but I've been looking all allong the documentation and the source code and I can't seem to find the proper way to do this using the REST adapter.

My scenario is simple: I have loaded all my app's contacts:

App.store.findAll(App.Contact)

Later on, I perform a POST to a particular location in my backend, which creates a few more contacts. Since the first request is cached, every action I perform (find, findAll, etc.) seems to return results from the cached Array instead of doing the round trip to the server.

What's the proper way to update the store with the new records from the backend?

Thanks and amazing work!

@josepjaume well for now, the only way to refresh records from server is to perform a findQuery

In a simple senario you should do App.Contact.createRecord({}) and them commit your store, this way your list of contacts in the store will be up to date.
It is probably not the best idea to bypass the store when manipulating your rest-api if you decide to use ember-data

First of all, thanks for answering so fast!

I don't get exactly how should I perform that findQuery - could you post an example?

In my particular scenario, I can't (or at least I think so) do it the standard way. I'm implementing a contact importer that adds new contacts based on the contents of a CSV.

Maybe returning the new contacts in the response and then passing it to the store's loadMany would be the best way to handle it?

$.ajax({url: '/import/csv', data: data, dataType: 'json', success: function(results){
  App.store.loadMany(App.Contact, results);
});

Yep this would work, and I think In your case it is a good way to do it.

As for findQuery, for example you could do this :

App.store.findQuery(App.Contact, {name: 'toto'});

and it will call

/contacts?name=toto

This kind of requests are never cached by ember-data

I've implemented the solution I proposed and it works, but I can confirm yours work too :D.

So, just for the record, those two options work:

App.store.findQuery(App.Contact, {});
App.store.loadMany(App.Contact, data.contacts);

I think I will stick with loading the new records because it seems more ember-idiomatic, but it's awesome to know the cache can be so easily overriden.

Thanks!

Can we close this? We do have an issue on reloading/loding more records stuff in #51

[josepjaume]

Absolutely! Sorry about that, I looked through the issues but I couldn't find what I was looking for.

Thanks for your help.

hello, i'm trying this approach

$.ajax({url: '/import/csv', data: data, dataType: 'json', success: function(results){
App.store.loadMany(App.Contact, results);
});

and i'm getting an error
"Uncaught Error: DS.StateManager:ember563 could not respond to event setData in state rootState.loaded. "

can you provide more details of how this works?
