My problem is, that the controller just send an undefiend and not the data from http of service. I inspect it with chrome. I am new at ionic. By calling the AppSqliDBFactory.getMasterdataId() method, it shows an undefiend, also at the scope variable.
.controller('ReadMasterdataCtrl', function ($scope, $state, $ionicNavBarDelegate, MasterdataService, AppSqliDBFactory){
$scope.masterdataId;
$scope.masterdataData;
AppSqliDBFactory.getMasterdataId().then( function (masterdata){
$scope.masterdataId = masterdata[0].masterdataId;
}).catch(function (err){
console.log(err);
});
//here is the error -> no data at "$scope.masterdataData = masterdata;"
MasterdataService.getMasterdataDB($scope.masterdataId)
.then(function (masterdata) {
$scope.masterdataData = masterdata;
console.log("getMasterdataDB respont");
console.log($scope.masterdataData);
}).catch(function (err) {
console.log(err);
});
})
//Service
.factory('MasterdataService', function ($q, $http, SERVER_URL) {
//Create JSON Object
var srv = {};
//Array for JSON Objects
srv.masterdata = [];
srv.getMasterdataDB = function (masterdataId) {
var deferred = $q.defer();
var masterdata;
var masterdataId = masterdataId;
var baseUrl = 'xxxx';
$http.get(SERVER_URL + baseUrl + masterdataId).success(function (response){
masterdata = response[0];
console.log(masterdata);
return deferred.resolve(masterdata);
}).error(function (err){
return deferred.reject(err);
});
return deferred.promise;
//return srv.getMasterdata();
};
// Public API
return {
getMasterdataDB: function ( masterdataId) {
return $q.when(srv.getMasterdataDB( masterdataId));
}
};
});
Simplified:
AppSqliDBFactory.getMasterdataId().then(function (masterdata) {
$scope.masterdataId = masterdata[0].masterdataId;
});
MasterdataService.getMasterdataDB($scope.masterdataId).then(function (masterdata) {
$scope.masterdataData = masterdata;
});
When MasterdataService.getMasterdataDB() is called, AppSqliDBFactory.getMasterdataId() may not have been resolved yet, so $scope.masterdataId can be undefined (which is probably what is happening in your case).
You have to call AppSqliDBFactory.getMasterdataId() after AppSqliDBFactory.getMasterdataId() has been resolved:
AppSqliDBFactory.getMasterdataId().then(function (masterdata) {
$scope.masterdataId = masterdata[0].masterdataId;
MasterdataService.getMasterdataDB($scope.masterdataId).then(function (masterdata) {
$scope.masterdataData = masterdata;
});
});
Or with chaining:
AppSqliDBFactory.getMasterdataId().then(function (masterdata) {
$scope.masterdataId = masterdata[0].masterdataId;
return MasterdataService.getMasterdataDB($scope.masterdataId);
}).then(function (masterdata) {
$scope.masterdataData = masterdata;
});

I have a large aggrogate query that required me to pass "allowDiskUse: true" as an option. This would not work with the aggegate as described here:
https://github.com/meteorhacks/meteor-aggregate/issues/11
My meteor method is defined here. When I call the method I need to wait for ondata to complete before anything is returned to the client, but nothing I try allows me to get that data in a safe way up to the front end.
Meteor.methods({
'getSummary': function (dept,startDate,endDate,filterType) {
f = myQuery(startdate,enddate,dayFinalGroup);
f.on("data", Meteor.bindEnvironment(function(row) {
//load an array or something here to return
}));
f.once("end", Meteor.bindEnvironment(function() {
// tidy up, in my case end the stream
}));
//here I'd return the array loaded
},
});
This is my front end.
Meteor.call(
'getSummary',0,Session.get('start_date'),Session.get('end_date'),1,
function(error, result){
if(error){
console.log(error);
} else {
Session.set('sumTotals',result);
}
}
);
Finally Got it. I utilized wrapSync
'getSummary': function (dept,startDate,endDate,filterType) {
console.log(dept);
console.log(startDate);
console.log(endDate);
console.log(filterType);
var startdate = new Date(startDate);
var enddate = new Date(endDate);
var arr = [];
f = myQuery(startdate,enddate,dayFinalGroup);
var fetchCursor = Meteor.wrapAsync(function fetchCursor (cursor, cb) {
cursor.each(function (err, doc) {
if (err) return cb(err);
if (!doc) return cb(null, { done: true }); // no more documents
arr.push(doc);
});
});
var myData = fetchCursor(f);
return arr;
I'm trying to create a custom command in nightwatch that runs a query on a Postgres database and returns the result. The query runs just fine and outputs the result to the console but then the execution of the test stops. I don't understand how callbacks work. How can I fix this custom command?
exports.command = function(sql, callback) {
var self = this;
var pg = require('pg');
var conString = self.globals.testinfo.connectionString;
var db = new pg.Client(conString);
db.connect(function(err) {
if(err) {
console.error('could not connect', err);
}
else {
db.query(sql, function(err, result) {
if(err) {
console.log('error running query', err);
}
else {
console.log(result.rows.length);
db.end();
}
});
}
}),
function(result) {
if (typeof callback === 'function') {
callback.call(self, result);
}
}
return this;
};
I had to wrap the database connection in a perform command to get this working. I'm not sure if this is the best way to handle the callback, but it works. Here's the updated version of the custom command:
exports.command = function(sql,callback) {
var self = this;
var pg = require('pg');
var cs = self.globals.testinfo.connectionString;
self.perform(function(self,done) {
pg.connect(cs,function(err,db,done) {
if(err) {
return console.error(err);
}
db.query(sql, function(err,result) {
done();
if(err) {
return console.error(err);
}
console.log(result.rows.length);
callback(result.rows[0]);
});
});
pg.end();
done();
});
};
Here's how I call the custom command in the test:
browser.myCustomCommand('select * from table limit 1;', function(row) {
browser.assert.deepEqual(row.column,'some value');
});
Can you try this:
exports.command = function(sql, callback) {
var self = this;
var pg = require('pg');
var conString = self.globals.testinfo.connectionString;
var db = new pg.Client(conString);
var cb= function(result) {
if (typeof callback === 'function') {
callback.call(self, result);
}
};
db.connect(function(err) {
if(err) {
console.error('could not connect', err);
cb(false);
}
else {
db.query(sql, function(err, result) {
if(err) {
console.log('error running query', err);
cb(false);
}
else {
console.log(result.rows.length);
db.end();
cb(true);
}
});
}
}),
return this;
};
And in your test :
'test' : function(browser){
browser.yourCommandName(sql,function(result){
console.log(result); //if connect is good result would be true and false if fail to connect.
});
}
Ps: the result in callback can be as an object(contain rows or anything you want), instead of boolean only in this example.
And Nightwatch is used for end-to-end testing, it is not aimed for Database testing,i think you should find another framework to test database connection.
I made a factory in service.js file
angular.module('app.services', [])
.factory('Auth', function($firebaseAuth){
var ref = new Firebase('https://loginmy-reddit.firebaseio.com');
return $firebaseAuth(ref);
})
.service('BlankService', [function(){
}]);
I want to use the ref for logging out the user which is in my main.js file
angular.module('app')
.controller('MainCtrl',function($scope,$state,Auth){
$scope.login = function(authMethod){
Auth.$authWithOAuthPopup(authMethod).then(function(authdata){
console.log(authdata);
$scope.signedInUser = authdata;
$state.go('menu.home');
}).catch(function(error){
console.log(error);
})
}
$scope.logout=function(){
ref.unauth();
//state.go('main');
}
How can i logout the user retaining the ref in service.js file..
You can extend your current service a bit like this:
.factory('Auth', function($firebaseAuth){
var ref = new Firebase('https://loginmy-reddit.firebaseio.com');
return {
login: function(){
return $firebaseAuth(ref);
},
logout: function () {
ref.unauth()
}
}
})
And use it in your controller like this:
$scope.login = function(authMethod){
Auth.login().$authWithOAuthPopup(authMethod).then(function(authdata){
console.log(authdata);
$scope.signedInUser = authdata;
$state.go('menu.home');
}).catch(function(error){
console.log(error);
})
}
$scope.logout=function(){
Auth.logout();
//state.go('main');
}
I've this javascript viewmodel defined:
function PersonViewModel() {
// Data members
this.Name = ko.observable();
this.Function_Id = ko.observable();
this.SubFunction_Id = ko.observable();
this.Functions = ko.observableArray();
this.SubFunctions = ko.observableArray();
// Whenever the Function changes, update the SubFunctions selection
this.Function_Id.subscribe(function (id) {
this.GetSubFunctions(id);
}, this);
// Functions to get data from server
this.Init = function () {
this.GetFunctions();
this.Function_Id('#(Model.Function_Id)');
};
this.GetFunctions = function () {
var vm = this;
$.getJSON(
'#Url.Action("GetFunctions", "Function")',
function (data) {
vm.Functions(data);
}
);
};
this.GetSubFunctions = function (Function_Id) {
var vm = this;
if (Function_Id != null) {
$.getJSON(
'#Url.Action("GetSubFunctions", "Function")',
{ Function_Id: Function_Id },
function (data) {
vm.SubFunctions(data);
}
);
}
else {
vm.SubFunction_Id(0);
vm.SubFunctions([]);
}
};
this.Save = function () {
var PostData = ko.toJSON(this);
var d = $.dump(PostData);
alert(d);
$.ajax({
type: 'POST',
url: '/Person/Save',
data: PostData,
contentType: 'application/json',
success: function (data) {
alert(data);
}
});
};
}
$(document).ready(function () {
var personViewModel = new PersonViewModel();
personViewModel.Init();
ko.applyBindings(personViewModel);
});
When the Submit button is clicked, the data from the select lists is posted, but NOT the 'Function_Id'.
When I choose a different value in the Function dropdown list, and the click the Submit button, the value for 'Function_Id' is correctly posted.
How to fix this ?
It's because the scope of the this keyword in javascript
this.Init = function () {
this.GetFunctions(); // this === PersonViewModel.Init
this.Function_Id('#(Model.Function_Id)'); // calls PersonViewModel.Init.Function_Id(...)
};
You should store the refrence to the PersonViewModel instance.
var self = this;
self.Init = function () {
self.GetFunctions();
self.Function_Id('#(Model.Function_Id)'); // calls PersonViewModel.Function_Id(...)
};
Firebug is giving me no error messages, but it's not working. The idea is regardless of whether the user picks an option from dropdown or if they type in something in search box, I want the alert() message defined below to alert what the value of the variable result is (e.g. {filter: Germany}). And it doesn't. I think the javascript breaks down right when a new Form instance is instantiated because I tried putting an alert in the Form variable and it was never triggered. Note that everything that pertains to this issue occurs when form.calculation() is called.
markup:
<fieldset>
<select name="filter" alter-data="dropFilter">
<option>Germany</option>
<option>Ukraine</option>
<option>Estonia</option>

Thank you for anyone who responds. I spent a lot of time trying to make this work.
The initial problem as to why the alert() was not being triggered when Form is instantiated is because, as you can see, the elements property belongs to the Form object, not fieldset object. And as you can see in the html, I place the fields as descendents of the fieldset object, not form.
