My JSON array of objects has the following structure:
https://i.sstatic.net/1IUVE.png
When generating a <ul>, I need to fetch an ID from an API for each <li>:
<ul>
<li v-for="genre in movie.genre_ids">
{{ genre }} // 19
</li>
</ul>
However, instead of displaying the number, I want to show the name of the genre associated with that ID.
How can I achieve this in my code?
Transform your genres array into an object with the IDs as keys:
computed: {
genresFormatted() {
const genres = {};
this.genres.forEach(genre => {
genres[genre.id] = genre.name;
});
return genres;
}
}
Now, accessing the name property when iterating becomes much simpler:
<li v-for="id in movie.genre_ids" :key="id">
{{ genresFormatted[id] }}
</li>
