the exception thrown:
lovefield.js:2113 Uncaught NotFoundError: Failed to execute 'transaction' on 'IDBDatabase': One of the specified object stores was not found.
Ello folks, I've been fighting with Lovefied for quite some time attempting to get my db schema initialized. I've wrapped everything in try catch blocks that I suspected there could be an issue and haven't gotten anything there. I've tracked it down to the lovefield function throwing the exception.scanRowId_ but, I'm still at a loss as to what is causing this. If it were something as straight forward as missing tables or missing fields It should have broke something on the way. Any thought on what is the cause?
Exibit 1: lovelace source code
the section that reads : try { var tx = opt_tx || db.transaction([tableName]); req = tx.objectStore(tableName).openCursor(null, "prev"); } catch (e) { reject(e); return; } is where the exception is being thrown.
lf.backstore.IndexedDB.prototype.scanRowId_ = function(opt_tx) {
var tableNames = this.schema_.tables().map(function(table) {
return table.getName();
}), db = this.db_, maxRowId = 0, extractRowId = function(cursor) {
if (this.bundledMode_) {
var page = lf.backstore.Page.deserialize(cursor.value);
return Object.keys(page.getPayload()).reduce(function(prev, cur) {
return Math.max(prev, cur);
}, 0);
}
return cursor.key;
}.bind(this), scanTableRowId = function(tableName) {
return new goog.Promise(function(resolve, reject) {
var req;
try {
var tx = opt_tx || db.transaction([tableName]);
req = tx.objectStore(tableName).openCursor(null, "prev");
} catch (e) {
reject(e);
return;
}
req.onsuccess = function(ev) {
var cursor = ev.target.result;
cursor && (maxRowId = Math.max(maxRowId, extractRowId(cursor)));
resolve(maxRowId);
};
req.onerror = function() {
resolve(maxRowId);
};
});
}, execSequentially = function() {
if (0 == tableNames.length) {
return goog.Promise.resolve();
}
var tableName = tableNames.shift();
return scanTableRowId(tableName).then(execSequentially);
};
return new goog.Promise(function(resolve) {
execSequentially().then(function() {
resolve(maxRowId);
});
});
};
Exibit 2: The code that builds the db schema
var buildSchema = function() { schemaBuilder = lf.schema.create(urlConfig.dsName, urlConfig.versionNumber); console.assert(tableSchemas, 'tableSchemas!=null'); console.assert(schemaBuilder, 'schemaBuilder!=null'); angular.forEach(tableSchemas, function(val, key) { var item = tableSchemas[key]; console.assert(item, 'item should not be null'); var tableName = item['tsName']; console.assert(tableName, 'tableName should not be null'); var fields = item['metaRecords']; console.assert(fields, 'fields should not be null'); var table; var isPrimary = ''; try { table = schemaBuilder.createTable(tableName); } catch (error) { console.log('failed to createTable(' + tableName + ')'); console.log(error); } for (var x = 0; x < fields.length; x++) { var field = fields[x]; try { table.addColumn(field['fieldName'], eval(field['dataType'])); } catch (error) { console.log('failed at table.addColumn(' + field['fieldName'] + ',' + eval(field['dataType']) + ')'); console.log(error); } try { if (field['isPrimary'] === '1') { isPrimary = field['fieldName']; } else { table.addNullable([field['fieldName']]); } } catch (error) { console.log('failed at table.addNullable(' + field['fieldName']); console.log(error); } } try { if (isPrimary !== '') { if (isPrimary === 'autoid') { table.addPrimaryKey([isPrimary], true); } else { table.addPrimaryKey([isPrimary]); } } } catch (error) { console.log('failed at table.addPrimaryKey('+ [isPrimary]+')'); console.log(error); } }); // persistservice.setVal('dbInitialized', true); };
Exibit 3: The code that breaks on
Specificly, the break happens at the promise return.
return schemaBuilder.connect().then(function(db) {
/**
* Instantiates the DB connection (re-entrant).
* @return {!IThenable<!lf.Database>}
*/
var getDbConnection = function() {
if (db_ != null) {
return db_;
}
if (!schemaBuilder) {
buildSchema();
}
return schemaBuilder.connect()
.then(function(db) {
db_ = db;
op = lovefield.op;
fn = lovefield.fn;
lf = lf;
onConnected_();
return db;
});
};
