Hey everybody.
I am using ion-datetime to select a date, however when the datepicker pops up it’s too low on the screen and I’ve been trying to move it to the center though nothing seems to work.

changing the picker position using top and also translateY but none of them work.
Here’s the relevant HTML line

<ion-label>{{ 'Execution date' | translate }}</ion-label>
          <ion-datetime [disabled]="!getExecLater()" displayFormat="MM/DD/YYYY" [(ngModel)]="transaction.bookingDate" name="bookingDate">

and here’s the relevant CSS code

page-new-transaction {
 .picker-wrapper {
      top:0px;
      transform: translateY(-50%);
    }
}

Thank you for your help

EDIT: I am not sure if the changes that my css file makes to .picker-wrapper are limited only to this page or to all instances of picker-wrapper along my app, maybe it is a bad idea

Hello. I just changed my code to have an ng-repeat in my column to this:

<ion-grid>
    <ion-row>
      <ion-virtual-scroll [items]="places" approxItemHeight="200px">
        <ion-col size="12" size-lg="6" *virtualItem="let place">
          <ion-card (click)='viewDetails(place.id)' no-padding no-margin>

When I have ng-repeat in ion-col and no virtual scroll, it works great. There are two columns. When I do it this way it creates one column with 50% width. Do you know what could be causing it to break to a new line even though it is properly doing the column size 6 and 50% max width (Verified by CSS)? Also if I place the ion-card-header before ion-row or ion-grid it creates a lot of errors. Beta 19 here.

I added the unit testing framework based on Karma and Jasmine to my ionic 3 project as described here and the refered link. Along the way I had to update webpack to v4 or more because the current Karma or Jasmine version depend on it.

Unit tests now work well but now my whole project fails to run because www/build does not contain main.js, vendor.js and main.css files. The app builds but fails with a blank screen, debugger 404s about the mentioned files.

How can I recreate the files? I can fall back to a previous version before karma and jasmine install and get things back up running, but I would like unit testing run parallel with a working app develop environment…

It does not allow me to upload my application to the AppStore Due to lack of functionality and in the design for general the app in Ios I had to add <preference name = “CordovaWebViewEngine” value = “CDVUIWebViewEngine” /> in the config.xml was what I found to the solution that all requests failed I am clear if it is because of this or if it is because of the very large and visual icons. What should I have at least to authorize it with good functionality? How do I solve the design?

Hello,

I have been practising Ionic 4 for a few days and I have a problem that I can’t solve on my own. Basically I have a tabs app (created with ionic start tabs). I also have a service and in my app and a function in it that returns a string. In my tab controller I declare a new variable and call the service function to assign its return value to the variable. However, this string does not automatically update in the view if it changes. I have tried reassigning the value to it inside ionViewWillEnter but this only gets called when the tab is loaded for the first time. Any ideas how I should address this?

export class Tab3Page {
  constructor (public storage: Storage, public router: Router, public platform: Platform, public ds: DataService) {}
  public loggedUser: any = this.ds.getLoggedUser();
  ionViewWillEnter() {
    this.refresh();
  }

  refresh() {
    let loggedUser = this.ds.getLoggedUser();
    console.log("Logged user: ", loggedUser);
    this.loggedUser = loggedUser;
  }

  logout () {
    //logout stuff
  }
}

In my view I use to display logged user’s username like:

{{ loggedUser.username }}

Thanks.

I’ve developed for a client an Ionic 3 app that sends informative text messages - SMS to clients.
For this app I received the following Google Play warning:

" Hello Google Play Developer,
In October, we announced updates to our Permissions policy that will limit which apps are allowed to request Call Log and SMS permissions. This is the second notification to let you know that this policy may impact one or more of your apps.

Only an app that has been selected as a user’s default app for making calls or text messages, or whose core functionality is approved for one of the exception use cases, will be able to access Call Log or SMS permissions.

Below, we’ve listed a sample of apps from your catalog which may not meet the requirements for permission requests.

Action required

Please read through the Permissions policy and the Play Console Help Center article, which describes intended uses, exceptions, invalid uses, and alternative options for use of Call Log or SMS permissions, to determine which of the following options apply to your affected app(s):

* Option 1) Your app does not require access to Call Log or SMS permissions: Remove the specified permissions from your app’s manifest, or migrate to an alternative implementation by January 9, 2019 . If you require additional time to remove permissions or migrate to an alternative option, submit a Permissions Declaration Form to request an extension until March 9, 2019.

* Option 2) Your app is a default handler, or you believe your app qualifies for an exception: If you haven’t already done so, submit a request using the Permissions Declaration Form by January 9, 2019 . We are currently reviewing submissions and will respond to your request. *Note: You do not need to make changes to your app in order to be eligible to submit a request.*"

It seems that the solution would be " Option 1) Your app does not require access to Call Log or SMS permissions: Remove the specified permissions from your app’s manifest."
But I don’t understand what to do. Where should I change and what? Should I modify my config.xml or the way I use this.sms.send() ? Or something else?

In my app I use SMS Plugin (https://ionicframework.com/docs/native/sms/)

To send the text messages I use a vector and call for each element the sms.send();

  for(var i=0;i<this.v_sms_complet.length;i++){
                if (this.v_sms_complet[i].CHECK_OK==true){
                         v_only_idsms_checked.push(this.v_sms_complet[i].id_sms);
                        
                          //send sms
                          this.sms.send(this.v_sms_complet[i].phone, this.v_sms_complet[i].text_sms);
                          this.sleep(0.5);//0.5 second pause after each sms
                }
        }

Thanks in advance!

Hi all! I’m quite new to Ionic and I’m working on a simple to-do list app for an assignment. I’m sort of stuck when it comes to updating a task. I’ve gotten as far as to when the user clicks “edit” on a task it present the Edit page along with the parameters passed by NavParams. But when the Update Task button is clicked I get the error: Cannot read property ‘set’ of undefined.

I’m not too sure what is causing this as I have no variable called ‘set’.

Clicking the edit button on a task does the following:

(click)="editTask(task.key, task.taskname, task.taskpriority)"

and the function is as follows:

editTask(id, taskname, taskpriority){
    //console.log(id, taskname, taskpriority);
    this.navCtrl.push(EdittaskPage, {
      key: id,
      taskname: taskname,
      taskpriority: taskpriority
    });  
  }

My EdittaskPage.ts has the following:

export class EdittaskPage {
	myTaskList$: Observable<Task[]>;
	task: Task = {
		id:'',
		taskname:'',
		taskpriority:'',
		listid:1
	}

  constructor(public navCtrl: NavController, public navParams: NavParams, public taskListService: TaskListService, public db: AngularFireDatabase) {

  	this.task.id = this.navParams.get('key'),
  	this.task.taskname = this.navParams.get('taskname'),
  	this.task.taskpriority = this.navParams.get('taskpriority')
  }


  closeModal(){
  this.navCtrl.pop();
  }
 	
  updateTask(task: Task){
  	this.taskListService.updateTask(task);
  }

}

On my EdittaskPage.html I have the following when the “save task” button is clicked:

(click) = "updateTask(task)"

which calls the function from the typescript file above
The function from the EdittaskPage.ts then calls a function from a service as follows:

private taskListRef = this.db.list<Task>
	 ('todoAppdb',ref=>ref.orderByChild("listid").equalTo(1));

	 constructor(private db: AngularFireDatabase){
	 }

     updateTask(task: Task){
	 	return this.taskListRef.update(task.key, task);
	 }

Any help would be much appreciated, thank you!
