使用此代碼時出現此錯誤,我想知道是什麼導致錯誤和任何可能的修復。無法讀取屬性「連接器」的未定義
型號代碼:
'use strict';
module.exports = function(Projects) {
Projects.getProjectData = function(cb) {
var sql = 'select * from projects';
// call sql query from postreSQL
Projects.app.datasources.postgres.connector.query(sql, function(err, result) {
if (err) {
console.log('Error retrieving projects result ...');
console.log(err);
return cb(err);
}
cb(err, result[0].jsondata);
});
}
Projects.remoteMethod(
'getProjectData', {
returns: [{
type: 'string',
required: true,
root: true
}],
http: {
verb: 'get'
}
}
);
};
我已經安裝回送連接器的PostgreSQL &生成的模型,但是當我試圖通過編寫自定義的API收到錯誤。
