Issue
I have a "post" component and I would like each one to have a different image, but they are generating with the same image.
In post component template i have:
<img src="{{this.post.image}}" alt="" style="width: 512px">
post component:
users: User[];
@Input() post: Post;
constructor(private user_service: UserService) { }
ngOnInit() {
this.users = this.user_service.getUsers();
}
in Home template:
<app-post *ngFor="let post of posts" [post]="post"></app-post>
Home component:
ionViewDidEnter() {
this.posts = this.posts_service.getPosts();
}
In postServices:
getPosts(): Array<Post> {
let res = this.http.get<Array<Post>>(this.API_URL);
let posts: Array<Post> = [];
res.subscribe(response => {
response.map(post => {
let p: Post = {} as Post;
p.id = post.id;
p.author_id = post.author_id;
p.created_at = post.created_at;
p.updated_at = post.updated_at;
p.image = post.image;
posts.push(p);
})
})
return posts;
}
Finnaly, posts data:
[
{
id: 1,
author_id: 1,
created_at: "2020-01-01T00:00:00.000Z",
updated_at: "2020-01-01T00:00:00.000Z",
image: "https://thiscatdoesnotexist.com"
},
[...]
]
All posts image are the same url.
I believe the current script is pulling the image for all posts at the same time, or in a single request. I would like each post to have its own request/image.

Solution
The problem is the same url, browser use a cached version of the result, you can add a random value at the end.
https://thiscatdoesnotexist.com/?v=<RANDOM>
HTML
<img [src]="randNumberUrl(this.post.image)" alt="" style="width: 512px">
TS
get randNumberUrl(u) {
return u + "?v=" + Math.floor(Math.random() * 99999)
}
