I am using Cakephp 2.3.0, loading following component.
class BreadCrumbsComponent extends Component {
public $components = array();
public $controller = null;
public function initialize($controller) {
}
public function startup($controller) {
$this->controller = $controller;
}
public function beforeRender($controller) {
}
public function shutDown($controller) {
}
public function beforeRedirect($controller, $url, $status = null, $exit = true) {
}
public function handle($controllerName = NULL, $actionName = NULL) {
pr($this->controller->modelClass);
}
}
It get error following error
Trying to get property of non-object [APP\Controller\Component\BreadCrumbsComponent.php, line 38]
I am unable to access $this->controller there. Any reason? How do I make it work?
Read here startup method is called after the controller so need to initialize controller in initialize method as below,
public function initialize(&$controller, $settings = array()) {
$this->controller = $controller;
}

I am having issue with the route and controller.
The error code consist of sql column not found which is looking for column id from items table. Which im quite curious due to the differences with my migration.

If I have a service injection like this:
export class MyService {
private fooService: IFooService;
public static $inject = [ "fooService" ];
constructor(fooService: FooService) {
this.fooService = fooService;
}
}
But I would like to give fooService a parameter in its constructor, so can I?
If you want to calculate something or provide the parameter in the run/config phase use a Provider
class MyServiceProvider implements ng.IServiceProvider {
private customParameter;
public setCustomParameter(val) {
this.customParameter = val;
}
public $get():Function {
return () => {
return new MyService(this.customParameter);
};
}
}
You now can inject the MyServiceProvider in the config phase and call the setCustomParameter.
If you know what what the parameter is, you can use regular injection and just define an angular variable like this:
angular.constant(CONSTANT_NAME, 'CONSTANT_VALUE');
export class fooService {
public static $inject = [ "CONSTANT_NAME" ];
constructor(CONSTANT_NAME) {
}
}
I started to learn angularjs and trying to put together Angularjs+Breezejs+EntityFramework.
Here is my context cs file:
public class GrantsDbContext : DbContext {
public GrantsDbContext() {
Database.SetInitializer<GrantsDbContext>(new MigrateDatabaseToLatestVersion<GrantsDbContext, Configuration>());
}
public DbSet<OrgItem> OrgList;
}
OrgItem is just model-class (contained: ID, FullName, ShortName), and I set automigrate, and write default connection string in Web.config
That's breeze controller cs file:
[BreezeController]
public class DbController : ApiController {
private EFContextProvider<GrantsDbContext> _contextProvider = new EFContextProvider<GrantsDbContext>();
[HttpGet]
public String Metadata() {
return _contextProvider.Metadata();
}
[HttpPost]
public SaveResult SaveChanges(JObject saveBundle) {
return _contextProvider.SaveChanges(saveBundle);
}
[HttpGet]
public IQueryable<OrgItem> OrgList() {
return _contextProvider.Context.OrgList;
}
}
Here is angular service, that created manager for breeze:
angular.module('app').factory("entityManagerFactory", ["breeze", emFactory]);
function emFactory(breeze) {
new breeze.ValidationOptions({ validateOnAttach: false }).setAsDefault();
var serviceName = "breeze/db";
var metadataStore = new breeze.MetadataStore();
var provider = {
newManager: newManager
};
return provider;
function newManager() {
var mgr = new breeze.EntityManager({
serviceName: serviceName,
metadataStore: metadataStore
});
return mgr;
}
}
That's my controller that called query:
angular.module("app")
.controller("OrgCtrl", ['entityManagerFactory', OrgCtrl]);
function OrgCtrl(entityManagerFactory) {
var vm = this;
vm.orgs = [];
var manager = entityManagerFactory.newManager();
var orgsQuery = new breeze.EntityQuery("OrgList").select("ID, FullName, ShortName");
manager.executeQuery(orgsQuery).then(succesCallback).catch(failCallback);
function succesCallback(data) {
vm.orgs = data.result;
}
function failCallback(error) {
console.log(error);
}
}
When I firstly started the app, database was created with one table '_MigrationHistory' and then I got the error: 'Error: cannot execute _executeQueryCore until metadataStore is populated.'
'localhost:49934/breeze/db/Metadata' is available (200 OK).
All libraries updated with nuget.
Help please to solve this problem!
Thanks!
I'm making a mp3/steaming radio with MVC, where I'm trying to load an URL from a array.
I have a radio class:
public class Radio
{
private var titel:String;
private var url:URLRequest;
private var cover:Bitmap;
public function Radio(titel:String, url:URLRequest, cover:Bitmap)
{
this.titel = titel;
this.url = url;
this.cover = cover;
}
public function getTitel():String {
return titel;
}
public function getURL():URLRequest {
return url;
}
public function getCover():Bitmap {
return cover
}
}
In the controller i have this:
public function selectRadio(radio:Radio):void{
model.selectRadio(radio);
}
In view I have the button with the eventlistner:
radio.addEventListener(MouseEvent.CLICK, function():void {
controller.selectRadio(model.getRadio(0));
});
And finally in the model i have:
private var radio:Radio = new Radio("P3", new URLRequest("http://live-icy.gss.dr.dk:80/A/A05L.mp3"), drp3);
private var radioArray:Array = new Array(radio);
private var r:Number;
public function selectRadio(radio:Radio):void {
var s:Sound = new Sound();
var chan:SoundChannel = s.play();
s.load();
trace("radio");
}
public function getRadios():Array {
return radioArray;
trace("All radio channels collected");
}
public function getRadio(radioNumber:int):Radio {
r = radioNumber;
return radioArray[radioNumber];
trace("Actual radio collected");
}
The problem is in the selectRadio function. I don't know how to load the URL in the arrays. It should be s.load(--something in here--); The reason why I'm doing this, is because I want to have multiple radio stations.
Hope you can help :)
var s:Sound = new Sound(radio.getURL());
var chan:SoundChannel = s.play();
load function will be called automatically by the constructor, also don't forget to stop previous SoundChannel.

i am trying to make a "game" in Flex similar to Shake&Fidget. I'm saving all the user data in a mysql database and I retrieve the data using ZendFramework (PHP).
I thought of saving all the user and character info I'm going to need into am AS class so I can use that data in every view.
The data recived from the database is correct. I was able to load it in my app labbels but everytime i changed views it had to ask it again, so i thought of making this classes in order to just ask once for the information.
I'll post here the files so it's all more clear.

The first View goes to the login screen, it works OK. So i'll go to the view that loads and "tries" to show the character data.

Thanks in advance to anyone that get so far in this help cry :D i'd apreciate any sugestions that you can make.
ok so the reason it doesn't work with data is that event though you said
data = new Character();
data is still actually an object (that now looks like a character). to make it work
var myChar:Character = Character(data); // cast it to a Character and it now knows the method
myChar.modStats()
the reason the other call didn't work is the way you called it:
Character::modStats(...)
This say look for a method called modStats in the namespace Character. Instead call this
character.modStats()
and it will work.
You Sir are my personal Hero :D, i've just tried it and it shows the data.
I changed the constructor for the character in Character.AS like this:
public function Character(obj:Object)
{
this._stats = new FinalStats();
this._gear = new GearList();
}
I'm not entirely sure if this is correct, but as you mentioned in your answer:
var myChar:Character = Character(data);
I supose i'll have to use that data object to initialice myChar...am i right? Well, later when i have the time i'll try to add new views and buttons to go through views and see if the data is there :D
