I have set up several form that takes info for an upload logic: like one takes then picture, one the description, one other setting. Now I want that this is all stored in one single form, but while it still worked when using different form now I get this error:
ERROR TypeError: Cannot read property 'controls' of undefined
I have no idea why is that. I also cannot submit a new description which I want to make with <div (ngSubmit)="addTag()">
Here is my code:

When ı run app and click notifications data appears in the template after a 10-15 seconds.
I checked the data with the console log when I was pulling datas, datas are coming normally(fast), the problem is that it shows late in HTML.
When I enter the notifications page : https://prnt.sc/11dtqkj
After waiting for 10-15 seconds :
https://prnt.sc/11dttn4
How can ı fix this problem ?
notifications.page.ts :
ionViewWillEnter(){
this.auth.currentUser.then(user=>{
this.userUid = user.uid
this.db.database.ref("/users/"+user.uid+"/notifications/").once("value",snap=>{this.notifications=[],snap.forEach(a=>{
this.db.database.ref("/users/"+a.child("who").val()+"/name").once("value",a2=>{let temp_a=a;
this.db.database.ref("/users/"+temp_a.child("who").val()+"/pp").once("value",a3=>{let temp_a2=temp_a; let a2_name = a2.val();
let type = temp_a2.child("type").val();
let not_key = temp_a2.key;
let name = a2_name;
let pp = a3.val();
let who = temp_a2.child("who").val();
let formId = temp_a2.child("formId").val();
let result = temp_a2.child("result").val();
if(type=="request"){
this.notifications.push({notKey:not_key,type:type,name: name,pp:pp,who:who,formId:formId});
}
else if(type=="response"){
this.notifications.push({type:type,name:name,pp:pp,who:who,result:result});

As per screenshot attachment, I would like all Ion Items sliding to open together when I trigger the Edit Button in a div,
Currently it only slides out the 1st delete ion items and the others remain unopened.
this is my code
HTML
<div class="editcontainer1" (click)="trigger()">Edit</div>
<ion-item-group *ngFor="let p of cart" #myItemsId >
<ion-item-sliding #slidingItem lines="none">
<div class="maincontainer">
<ion-item>
</ion-item>
<ion-item-options side="end">
<ion-item-option color="danger"
(click)="removeCartItem(p)">
<div style="color: seashell;">Delete</div>
</ion-item-option>
</ion-item-options>
</div>
</ion-item-sliding>
</ion-item-group>
TS
trigger() {
this.itemSlidingList.open('end');
}
else {
this.itemSlidingList.close();
}
how do i modify to become opens all?
openAllSlides(item) {
let a = Array.prototype.slice.call(item.el.children)
a.map((val) => {
val.open();
})
}
thank you.
Screenshot
you can do something like:
<ion-list>
<ion-item-group #myItemsId> <!-- use ITEM id for group -->
<ion-item-sliding *ngFor="let item of items">
<ion-item>
<ion-label>Item Options</ion-label>
</ion-item>
<ion-item-options side="end">
<ion-item-option >Unread</ion-item-option>
</ion-item-options>
</ion-item-sliding>
</ion-item-group>
</ion-list>
<ion-button (click)="openAllSlides(myItemsId)">open all slides</ion-button>
.ts
openAllSlides(item){
let a = Array.prototype.slice.call( item.el.children )
a.map((val)=>{
val.open();
})
}
I've try to use console.log to view the value, but noticeSet2[index] value is undefined. And when I print noticeSet, it will show all the data in the array. And I've try to print the index at console.log, and it show the index that match the array.
I try to create a sub menu in the sub menu of a main menu which is noticeSet and the main menu work just fine. I try the similar method and it doesn't work. all I need to solve now is to show the noticeSet2[index] value. Thanks
toggleItem(index, item) {
//this.noticeSet2[index].open = !this.noticeSet2[index].open;
console.log("here");
console.log(this.noticeSet2[0]);
console.log(this.noticeSet2[index]);
console.log(index);
let obj = {resident_id: this.resident_id,id: item.id}
this.authService.postData(obj, "getSubCategoryList").then((result) =>{
this.responseData = result;
if(this.responseData.feedData){
//this.noticeSet2[item.id] = this.responseData.feedData;
this.noticeSet3[this.noticeSet2[item.id]] = this.responseData.feedData;
this.isDataAvailable = true;
//console.log(this.noticeSet);
}
}, (err) => {
});
}
<ion-list *ngFor="let item of noticeSet; let i = index;" lines="none" class="accordion-list" detail="false"
no-padding >
<button ion-item tappble style="font-weight:bold;color:#424242;" (click)="getSubCategoryList(i,item)" [ngClass]="{'section-active':item.open,'section':!item.open}">

This is because you use value inside the promise.
You have two ways to proceed:
First one is to use
.then( function() => { [...] }
instead of
.then((result) => { [...] }
it will works.
The Second one is to use special variable NOT inside your {}.
var that = this;
// ...
.then(function() { that.variable })
Hope this help.
I have an ionic list that is filled with an ngfor. The list fills without problem, it locks up a bit, however in the console a syntax error appears for one of the ngfor tags.
My Ionic info is:
ionic (Ionic CLI) : 4.12.0
Ionic Framework : ionic-angular 3.9.2
#ionic/app-scripts : 3.2.3
This is the code of my template:
<ion-content padding>
Tap sobre el producto para añadirlo a favoritos.

<h2 style="padding: 15px 15px;"> {{ task.nombre }}
<ion-icon *ngIf="task.favs == 1" name="star"></ion-icon>
<ion-icon *ngIf="task.favs == 0" name="star-outline"></ion-icon>
