Learning Spine.js for a new app. The Spine framework is elegant. I am not quite able to get the Ajax persistence working. No error messages, just no activity.
I have a REST api http://localhost:8080/services/api/myservice/persons
that returns a JSON list of Person objects, via both the browser and the jQuery.ajax(...)
call below in this minimal test.
But calling Person.fetch() yields neither ajaxSuccess
nor ajaxFailure
, nor trigger a refresh
event. Nor does the server register a request. I included "ajax.js" and extended Spine.Model.Ajax. Presumably I'm missing a basic setup, would be grateful for hints.
<script type="text/javascript" src="/appLib/jquery-1.7.js"></script>
<script type="text/javascript" src="/appLib/spine/spine.js"></script>
<script type="text/javascript" src="/appLib/spine/ajax.js"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
Spine.Model.host = "http://localhost:8080/services/api/myservice";
var Person = Spine.Model.sub();
Person.configure("firstName", "lastName");
Person.extend("Spine.Model.Ajax");
// these callbacks are never called
Person.bind("refresh", function() {alert("refreshed "+Person.count());}); // never called
Person.bind("ajaxSuccess", function() {alert("ajax success");}); // never called
Person.bind("ajaxError", function(record, xhr, settings, error) {
alert("ajaxError"+error); // never called
});
Person.fetch(function() {alert("Fetch "+Person.count());}); // 0
Person.each(function() {alert("Found");}); // never called
// but this direct ajax call works fine
jQuery.getJSON(Spine.Model.host + "/persons", function(result) {
for (var i=0, l=result.length; i<l; i++) {
var person = Person.init(result[i]);
person.save();
}
alert(Person.count()); // shows correct result
Person.each(function(p) {alert(p.lastName);}); // shows correct results
});
});
</script>
Yes, you're extending it with a string - that's never going to work.
Change:
Person.extend("Spine.Model.Ajax");
To:
Person.extend(Spine.Model.Ajax);
