Ich verwende Ionic zum Erstellen meiner Hybrid-App.Ionic + sqlite: Zugriff auf SQLite-Tabellen auf IOS (Cordova SQLite) nicht möglich
Ich benutze SQLite als Datenbank. Auf Android kann ich ohne Probleme auf alle meine gespeicherten Daten zugreifen, aber auf iOS schlägt es fehl. Ich Abrufen der folgende Fehler in der Xcode-Debug-Konsole (ich bin mit einem iPhone 6s Plus Test):
[debug] OPEN database: rcsappmobile.db
[debug] Initializing SQLitePlugin
[debug] Detected docs path: /var/mobile/Containers/Data/Application/<UUID>/Documents
[debug] Detected Library path: /var/mobile/Containers/Data/Application/<UUID>/Library
[debug] no cloud sync at path: /var/mobile/Containers/Data/Application/<UUID>/Library/LocalDatabase
[debug] open full db path: /var/mobile/Containers/Data/Application/<UUID>/Library/LocalDatabase/rcsappmobile.db
[debug] Good news: SQLite is thread safe!
[debug] DB opened: rcsappmobile.db
[debug] SELECT av.id, av.name FROM app_venues av WHERE av.active ORDER BY av.venuename ASC
[debug] result:
[debug] {"$$state":{"status":0}}
[debug] MultipleResultHandler
[debug] Default Error Handler -> Error processing SQL: undefined: undefined
[debug] Default Error Handler -> Error processing SQL: 5: a statement error callback did not return false: no such table: app_venues
Bisher mein Problem.
EDIT: Es scheint, als ob das Plugin, das ich verwende, um die Datenbank zu seinem Ziel zu kopieren, löscht alle vorbelegten Inhalt! Ich habe die Datenbank über xcode überprüft und es war leer!
, dass mein Code ist:
controllers.js:
var dashboardCtrl = function ($scope, $ionicPlatform, $cordovaDevice, DbAccess) {
console.log('dashboardCtrl');
$ionicPlatform.ready(function() {
console.log('dashboard -> platform ready');
DbAccess.openDb();
});
};
dashboardCtrl.$inject = ['$scope', '$ionicPlatform', '$cordovaDevice', 'DbAccess'];
var venuesCtrl = function ($scope, $ionicPlatform, $cordovaDevice, VenuesQueries) {
console.log('venuesCtrl');
$ionicPlatform.ready(function() {
console.log('venue -> platform ready');
VenuesQueries.getVenues().then(function(result) {
$scope.outputs = result;
var len = Object.keys(result).length;
if(len > 0) {
$scope.outputs = result;
} else {
console.log('No records found in database.');
}
}, function(error) {
console.error(error);
});
});
