I setting up a scenario very similar to the Editable Row example from the x-editable demo site. In this scenario, a there is a simple table with three columns for data and a fourth for edit and delete buttons. A third button outside of the table adds a row to the table. When the form is editable, the data columns become editable (the primary feature of x-editable library). For this demo, the first column becomes a simple text edit and the second two columns become drop lists.
The table is created by having an ng-repeat on a row template. I need to do a few different things that all involve accessing the scope created by the ng-repeat. I need to
- detect when the row is editable and when it is not
- filter the options for the second drop list when the first drop list changes
In order to try to work with this demo, I've added a controller for the individual row. That has given me some access to the form (name = rowform), but I'm still not able to set a watch on the "make" property. I can't even find what property of the form is changing when the user makes a selection.
How do I set up a watch on the 'make' property?
Page Controller
angular.module('app').controller("quoteBuckingRaterController",
function ($scope, $q, $filter, listService, transactionDataService) {
$scope.equipment = [];
$scope.makes = [];
$scope.models = [];
$scope.showModel = function(equip) {
if(equip.model) {
var selected = $filter('filter')($scope.models, {id: equip.model});
return selected.length ? selected[0].name : 'Not set';
} else {
return 'Not set';
}
};
$scope.showMake = function(equip) {
if (equip.model) {
var selected = $filter('filter')($scope.models, { id: equip.model });
if (selected.length && selected.length > 0) {
if (equip.make != selected[0].make)
equip.make = selected[0].make;
return selected[0].make;
}
else {
return 'Not set';
}
} else {
return 'Not set';
}
};
$scope.checkName = function (data, id) {
if (!data) {
return "Description is required";
}
};
$scope.checkModel = function (data, id) {
if (!data) {
return "Model is required";
}
};
$scope.saveEquipment = function (data, id) {
$scope.inserted = null;
};
$scope.cancelRowEdit = function (data, id) {
$scope.inserted = null;
};
$scope.removeEquipment = function(index) {
$scope.equipment.splice(index, 1);
};
$scope.addEquipment = function() {
$scope.inserted = {
id: $scope.equipment.length+1,
name: '',
make: null,
model: null
};
$scope.equipment.push($scope.inserted);
};
$scope.filterModels = function (make) {
$scope.models = _.where($scope.allModels, function(item) {
return item.make == make;
});
};
//called by another process when page loads
$scope.initialize = function (loaded) {
return $q(function (resolve, reject) {
if (!loaded) {
listService.getEquipmentModels().then(function (data) {
$scope.allModels = data;
$scope.models = data;
//uses underscore.js
$scope.makes = _.chain(data)
.map(function (item) {
var m = {
id: item.make,
name: item.make
};
return m;
})
.uniq()
.value();
resolve();
});
}
});
}
});
Row Controller
angular.module('app').controller("editRowController",
function ($scope) {
$scope.testClick = function () {
alert('button clicked');
};
$scope.make = null;
$scope.$watch('make', function () {
alert('how do I tell when the make has been changed?');
this.$parent.$parent.filterModels(make.id);
});
});
