尝试访问$ scope.mySlot.id,但它未定义。无法访问资源的.id值
$scope.removeMe = function() {
var shouldRemove = confirm('Remove you from this field trip?');
if (shouldRemove) {
var data = null;
UserService.me().then(function(me){
var data = {userID: me.id, eventID: tripID}
console.log(data);
return data;
}).then (function(data){
var mySlot = GreenTripFilledSlotsFactory.get(data);
return mySlot;
}).then (function(mySlot) {
$scope.mySlot = mySlot;
console.log("this is $scope.mySlot: ");
console.log($scope.mySlot); //this shows up as a resource with proper values
console.log("this is $scope.mySlot.id: ")
console.log($scope.mySlot.id); //this is undefined
}).then (function(success){
return $scope.mySlot.$delete(); // this isn't working'
}).then(function(success){
console.log('mySlot deleted');
route.reload();
}).catch(function(error){
console.log(error);
})
}
};
在console.logs中显示$ scope.mySlot作为资源,它列出了它的值。但我很困惑为什么$ scope.mySlot.id是未定义的。
工厂:
.factory('GreenTripSlotsFactory', ['$resource', function($resource) {
return $resource('/api/GreenTripSlots/:id/', {id: '@id' }, {
update: {method: 'PUT' }
});
}])
.factory('GreenTripFilledSlotsFactory', ['$resource',
function($resource) {
return $resource('/api/GreenTripSlots/:userID/:eventID/:slotID',
{id: '@id' }, {
update: {method: 'PUT' }
});
}])
BACKEND contollers:
// = /api/GreenTripSlots/:userID/:eventID
router.route('/:userID/:eventID')
.get(function(req,res) {
procedures.procGetSlotByUserAndTrip(req.params.userID,
req.params.eventID).then(function(greenTripUserSlot){
res.send(greenTripUserSlot);
}, function(err) {
console.log(err);
res.sendStatus(500);
})
})
// = /api/GreenTripSlots:/userID/:eventID/:slotID
router.route('/:userID/:eventID/:slotID')
.get(function(req,res) {
procedures.procGetSlotByUserAndTrip(req.params.userID,
req.params.eventID).then(function(greenTripUserSlot){
res.send(greenTripUserSlot);
}, function(err) {
console.log(err);
res.sendStatus(500);
})
})
.delete(function(req, res){
procedures.procRemoveMe(req.params.slotID).then(function(){
res.sendStatus(204);
}, function(err) {
console.log(err);
res.sendStatus(500);
});
})
后台程序:
exports.procGetSlotByUserAndTrip = function(userID, eventID) {
return db.fnRow('procGetSlotByUserAndTrip', [userID, eventID])
}
exports.procRemoveMe = function(slotID) {
return db.fnEmpty('procRemoveMe', [slotID])
SQL存储过程获取:
CREATE DEFINER=`CharleyHannah`@`localhost` PROCEDURE
`procGetSlotByUserAndTrip`(pUserId INT, pEventId INT)
BEGIN
SELECT *
FROM userEvents u
WHERE u.userID = pUserId & u.eventID = pEventId;
END
SQL存储过程进行删除:
CREATE DEFINER=`CharleyHannah`@`localhost` PROCEDURE
`procRemoveMe`(pSlotId int)
BEGIN
DELETE
FROM userEvents
WHERE id = pSlotId;
END
我正在成功地获得me.id(其是用户表中的用户ID)。 然后,我通过它成功地获取行中,其中userID和tripID存在于一个联接表中。 这显示在$ scope.mySlot的console.log中但是我无法访问$ scope.mySlot中的数据以使用删除请求 – lightcollector7
