AngularJS inline edit inside of ng-repeat - angularjs

Question

Im working with AngularJS to display a table of app keys (app identifiers) and I would like to use an edit button to display a small form in that table row. Then the user can edit the fields and click "save" or "cancel"
Demo: http://jsfiddle.net/Thw8n/
I have the inline form working great. I click edit and a form appears. Cancel works great too.
My problem is
How do I connect the save button with a function that will make a $http call to an API
How do I get the data from that row to send to the $http call?
How do I disable editMode once the call comes back?
Here is the actual code Im using in my controller (in the JSFiddle Im not able to make the http call). The first $http fills out the form, the editAppKey function is what is called by the save button.
function AppKeysCtrl($scope, $http, $location) {
$http({
method: 'POST',
url: 'http://' + $location.host() + ':1111/sys/appkey/save',
data: {
// How do I get the data?
}
}).
success(function(data, status, headers, config) {
$scope.appkeys = data;
}).
error(function(data, status, headers, config) {
$scope.appkeys = [{ "appkey" : "ERROR", "name" : "ERROR", "created" : "ERROR" }];
});
$scope.editAppKey = function() {
$http({
method: 'POST',
url: 'http://' + $location.host() + ':1111/sys/appkeys'
}).
success(function(data, status, headers, config) {
alert("Success!");
$scope.editMode = false;
}).
error(function(data, status, headers, config) {
alert("There was an error.");
});
}
}

When we press on "Edit" button and change one of fields , we also change our main model appkeys. Its mean that on "Cancel" we need restore old model.
Its mean that we need at least:
So this is a snippets of HTML:
<td>
<button type="submit" data-ng-hide="editMode" data-ng-click="editMode = true; editAppKey(entry)" class="btn btn-default">Edit</button>
<button type="submit" data-ng-show="editMode" data-ng-click="editMode = false; saveField()" class="btn btn-default">Save</button>
<button type="submit" data-ng-show="editMode" data-ng-click="editMode = false; cancel()" class="btn btn-default">Cancel</button>
</td>
And our controller:
$scope.newField = {};
$scope.editing = false;
$scope.appkeys = [
{ "appkey" : "0123456789", "name" : "My new app key", "created" : tmpDate },
{ "appkey" : "abcdefghij", "name" : "Someone elses app key", "created" : tmpDate }
];
$scope.editAppKey = function(field) {
$scope.editing = $scope.appkeys.indexOf(field);
$scope.newField = angular.copy(field);
}
$scope.saveField = function() {
if ($scope.editing !== false) {
$scope.appkeys[$scope.editing] = $scope.newField;
$scope.editing = false;
}
};
$scope.cancel = function() {
if ($scope.editing !== false) {
$scope.appkeys[$scope.editing] = $scope.newField;
$scope.editing = false;
}
};
Demo Fiddle
[EDIT]
I you want to edit several rows at once, use array of newFields instead $scope.newField

You can pass e.g. current index as a parameter to the editAppKey() function:
... data-ng-click="editAppKey($index)"
and in the JS file:
$scope.editAppKey = function(index) {
window.console.log(appkeys[index]); // do what ever you want
}
as for the disabling once the request is back. If I undestand, you want to allow only one time edit and after editAppKey() is called once on some row, disable it, right? If so, maybe something like
<button type="submit" data-ng-hide="editMode" data-ng-click="editMode = true" class="btn btn-default"
data-ng-disabled="entry.isDisabled">Edit</button>
and in the editAppKey() function, something like
$scope.editAppKey = function(index){
$http.post(url, data).onsuccess(function(){
$scope.appkeys[index].isDisabled = true;
});

In case someone need multiple edit at once:
Just do the following:
on html cancel button, pass the index
data-ng-click="editMode = false; cancel($index)"
on JS side:
1) $scope.newField = {}; to $scope.newField = [];
2) inside editAppKey function, $scope.newField = angular.copy(field); to $scope.newField[$scope.editing] = angular.copy(field);
3) change the saveField function to:
$scope.saveField = function(index) {
$scope.appkeys[$scope.editing] = $scope.newField;
};
4) change the cancel function to:
$scope.cancel = function(index) {
$scope.appkeys[index] = $scope.newField[index];
$scope.editing = false;
};
