$resource callback?

[Jehu]

Hi,

i can't find out how to get a callback when data loading from server
has finished.
I've found some ideas to use $defer, but this is not acceptable
because one can not know how long the timeout must be set.

Can anyone give a hint for this topic?
Thanks!

myResource.$get([params,] callbackFn);

/i

I think your question is not about data loading, but initial template, is that right?
If so, the answer is that in Angular, one does write a directive or widget, put it on the template and it will be called by Angular in the right time.
If that's not clear, tell us your story,so we could help you figuring it out.

Oh, now I see the subject, it is about $resource service.

Thank you, i've tryed this, but now it works with an extra call of
self.$eval().
Seems to be a timing problem?

Here's my service:

angular.service('ResContacts', function($resource) {
var self = this;
return $resource(
'/contacts/:id',
{ id: '@_id' },
{
'save': { method: 'POST' },
'list': { method: 'GET', isArray: true },
'update': { method: 'PUT' },
'remove': { method: 'DELETE' }
}
);
}, { $inject:['$resource'], $eager:true });

And now it works like this in controller:

ResContacts.list(function(res) {
self.contacts = res;
self.$eval();
jQuery('#table-contacts').dataTable( {"aoColumns":
self.tblColumns} );
});

It works only with self.$eval() after setting self.contacts.
But it's ok, i think. Right?

it works, but it's a hack.

you are mixing the presentation and business logic. whenever you reference the dom from your controller a kitty dies, that's why you need the extra eval. :-)

create a table widget a feed it with the data from the controller. that's the right way to deal with this.
