I have an image uploaded to Firestore storage which I want to display on my website. I am then storing the url for this image in my Firestore document:
I can successfully reference the data for this document and all the others in the collection, then display in my html as so:
<ng-container *ngIf="infinite | async as products">
<cdk-virtual-scroll-viewport itemSize="100" (scrolledIndexChange)="nextBatch($event, (products[products.length - 1].data.productName))">
<div class="product-row" fxLayout="row wrap" fxLayout.xs="column wrap" fxFlexFill fxLayoutAlign="center center">
<div fxFlex.gt-xs="50%" fxFlex.gt-md="30%" *cdkVirtualFor="let p of products; let i = index; trackByIndex">
<mat-card class="product-tile">
<img class="product-thumbnail" src="p.data.thumbnail" [routerLink]="p.id">
<div class="product-brand">
{{ p.id }}
</div>
<div class="product-details">
<span id="product-name">{{ p.data.productName }}</span> <span id="product-price">{{ p.data.price }}</span>
</div>
<div class="add-to-pad-button">
<button (click)="openDialog(p.id)" mat-raised-button color="accent">Add to Pad</button>
Click Me
</div>
</mat-card>
</div>
</div>
</cdk-virtual-scroll-viewport>
</ng-container>
In theory, I would assume that calling the reference to thumbnail, which is the image URL, would result in the image being displayed. However, the result is:
Am I incorrectly referencing the image URL?
Change p.data.thumbnail to {{ p.data.thumbnail }}

I am creating an Angular page to display the results of football matches and would like a warning message to be displayed when there are no matches. I used an ngIf to check if the array containing all matches is different from 0 but specifying in the else the ng-template to refer to gives me an error "Property 'noMatch' does not exist on type 'MainPageComponent'".
This is the piece of html code in which the matches are displayed, and if there are none, I would like the message contained in the ng-template to be displayed.
<div *ngIf="live.length > 0">
<h1 style="color: red;">Live ScoreBoard</h1>
<div *ngFor="let data of live">
<div class="title-box">
<p id="elapsed">{{ data.fixture.status.elapsed }}'</p>
</div>
<div class="title-box">
<div class="team">
<img id="homeLogo" src="{{ data.teams.home.logo }}">
<p id="homeName">{{ data.teams.home.name }}</p>
</div>
<p id="goals">{{ data.goals.home }} - {{data.goals.away}}</p>
<div class="team">
<img id="awayLogo" src="{{ data.teams.away.logo }}">
<p id="homeName">{{ data.teams.away.name }}</p>
</div>
</div>
<hr>
</div>
<ng-template #noPartite>
<p>No matches are scheduled today, however you can check the results of past matches <a routerLink="/matchday">here</a>and the standings here.</p>
</ng-template>
</div>
This is what the terminal returns
Error: src/app/Components/main-page/main-page.component.html:3:43 - error TS2339: Property 'noPartite' does not exist on type 'MainPageComponent'.
3 <div *ngIf="live.length > 0; else noPartite">
~~~~~~~~~
src/app/Components/main-page/main-page.component.ts:7:16
7 templateUrl: './main-page.component.html',
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Error occurs in the template of component MainPageComponent.
The position of noPartite template is important. You have to move out from <div> element with *ngIf as below:
<div *ngIf="live.length > 0; else noPartite">
...
</div>
<ng-template #noPartite>
...
</ng-template>

I am using p-picklist and I want to edit target list span data used for displaying the value.
I am using the source code: https://primefaces.org/primeng/showcase/#/picklist
How can I make product name editable in the target list.
<p-pickList
[source]="sourceProducts"
[target]="targetProducts"
sourceHeader="Available"
targetHeader="Selected"
[dragdrop]="true"
[responsive]="true"
[sourceStyle]="{'height':'30rem'}"
[targetStyle]="{'height':'30rem'}"
filterBy="name"
sourceFilterPlaceholder="Search by name"
targetFilterPlaceholder="Search by name"
>
<ng-template let-product pTemplate="item">
<div class="product-item">
<div class="image-container">
<img
src="assets/showcase/images/demo/product/{{product.image}}"
[alt]="product.name"
class="product-image"
/>
</div>
<div class="product-list-detail">
<h5 class="p-mb-2">{{product.name}}</h5>
<i class="pi pi-tag product-category-icon"></i>
<span class="product-category">{{product.category}}</span>
</div>
<div class="product-list-action">
<h6 class="p-mb-2">${{product.price}}</h6>
<span
[class]="'product-badge status-' + product.inventoryStatus.toLowerCase()"
>{{product.inventoryStatus}}</span
>
</div>
</div>
</ng-template>
</p-pickList>
Turning the <h5 class="p-mb-2">{{product.name}}</h5> into an input with [(ngModel)]="product.name" seem to work.
In order to check if the templated item is listed under target and not under source, you can check the element's position on the DOM; if it is inside .p-picklist-target, show the input, else show h5.

it's my first time posting so critic for etiquette.
been using *ngFor="let item of items" in a ionic project but I ran into a problem, that being that once *ngFor is used in the a tag, I don't know who I can transfare the data for a selected item into a tag that is outside of the original tag containing it.
code:
<ion-list>
<div class="wrapper">
<ion-item-group class="day" *ngFor="let day of Excursion_Schedule" >
<ion-item-divider class="dayCard" (click)="day.displayItineraryFlag= !day.displayItineraryFlag"><ion-icon name="ios-arrow-forward" item-right></ion-icon>{{day.ExcSch_date | date:'dd'}}</ion-item-divider>
<!-- CODE I WANT TO MOVE --> <ng-container *ngIf="day.displayItineraryFlag">
<div ion-item class="cardtitle" *ngFor="let place of day.Excursion_CustomRoadMap">
<p>check</p>
<ion-item-divider class="cardtitle" *ngIf="place.Exc_CustomRoadMap_Name" (click)="place.displayStationDetailsFlag= !place.displayStationDetailsFlag">
<div class="textW">{{place.Description}} - {{place.Exc_CustomRoadMap_StartTime}}</div>
<br>
<div *ngIf="place.displayStationDetailsFlag">
<div class="mapNpic">
<img class="pics" src="{{place.Photo}}" alt="">
<img class="pics" src="https://media-cdn.tripadvisor.com/media/photo-s/14/5f/96/77/nice-view-of-the-sunset.jpg" alt="">
</div>
<div class="dits">
<br> <br>
<h3>Adress</h3>
<h3>Phone Number</h3>
<h3>Email</h3>
<h3>Website</h3>
</div>
</div>
</ion-item-divider>
</div>
</ng-container>
</ion-item-group>
</div>

<!-- PLACE WHERE I WANT TO MOVE ng-container TO -->

Just use interpolation. To achieve this you have to write the selected item into a variable and then interpolate it into the outer area. Here is an example:
TS
selectedItem: any;
Excursion_Schedule: Array<any> = [];
HTML
<div><span>{{selectedItem}}</span>
<div *ngFor="let day of Excursion_Schedule">
<!-- write the selected day into the local variable here -->
</div>
</div>
<div class="container">
<div class="container__usernamesContainer">
<a class="container__usernamesContainer--text" *ngFor="let user of getUsers()">
Username: {{ user.getUsername() }}
</a>
</div>
<div class="container__statusesContainer">
<span class="container__statusesContainer--text" *ngFor="let status of getUsers()">
<span [ngClass]="'{{ user.getUsername() }}'">
Status: {{ status.getStatusLabel() }}
</span>
</span>
</div>
</div>
i am trying to set [ngClass]="'{{ user.getUsername() }}'" dynamically, and i do not get the value. how can i achive that?
There are two things going on here. You have two different *ngFor loops both iterating over the array returned by getUsers(). One you do let users of getUser(), and the other you do let status of getUsers(). But you then try to uncalled user instead of status in the second loop. Below is what your code should be.
<div class="container">
<div class="container__usernamesContainer">
<a class="container__usernamesContainer--text" *ngFor="let user of getUsers()">
Username: {{ user.getUsername() }}
</a>
</div>
<div class="container__statusesContainer">
<span class="container__statusesContainer--text" *ngFor="let status of getUsers()">
<span [ngClass]="status.getUsername()">
Status: {{ status.getStatusLabel() }}
</span>
As you are using property binding you don't need to use interpolation:
[ngClass]="user.getUsername"
You just need to bind the property that you want to use
So this is kinda difficult to explain so I have a sort video of the issue with annotations
It seems like static text is not rendering (see the H3 tag). The dynamic stuff like {{ foo.bar }} and things in loops seem to work fine. It is happening to all pages as far as I can tell.
I used the AngularClass repo as a starting point.
When the page is loaded directly or refreshed (F5 etc)
When its accessed via a link from another page

<h3>GPS raw data</h3>
<div class="row" *ngIf="gps && gps.location">

<div class="col-md-4">
<strong>Latitude:</strong> {{ gps.location.latitude }}

There is no errors in the console.

Another image to possibly clear up what the actual problem is. Note the HTML has content in the title, its hard coded. But its not displayed.
1) 1st solution, it should be *ngIf and not ng-if
<div class="row" *ngIf="gps && gps.location"> //<<<===here
<div class="col-md-4">
<strong>Time:</strong> {{ gps.location.timestamp }}
</div>
<div class="col-md-4">
<strong>Latitude:</strong> {{ gps.location.latitude }}
</div>
<div class="col-md-4">
<strong>Longitude:</strong> {{ gps.location.longitude }}
</div>
</div>
2) 2nd solution, don't use *ngIf and use ?. operator as shown below,
<div class="row" >
<div class="col-md-4" >
<strong>Time:</strong> {{ gps?.location.timestamp }} //<<<==here
</div>
<div class="col-md-4">
<strong>Latitude:</strong> {{ gps?.location.latitude }} //<<<==here
</div>
<div class="col-md-4">
<strong>Longitude:</strong> {{ gps?.location.longitude }} //<<<==here
</div>
</div>
I encountered the same issue on Chrome and fixed it by removing the font-size style applied on that element. Not sure why, might be a bug of Chrome.
