If you've ever worked with the TMDb (The Movie Database) api for movies, you might have encountered this issue. I am struggling to display the genre names for each movie shown. My goal is to replace the numbers in genre_ids from the movies api with their respective name from the genres api because displaying numbers to users doesn't provide much information! However, I haven't been able to achieve the desired outcome and I'm not certain of the correct approach...
Movie adapter
import DS from 'ember-data';
const apiKey = 'SOME_API_KEY_HERE';
export default DS.RESTAdapter.extend({
host: `https://api.themoviedb.org/`,
namespace: '3',
pathForType() {
return `discover/movie?sort_by=popularity.desc&api_key=${apiKey}`;
},
});
Genre adapter
import DS from 'ember-data';
const apiKey = 'SOME_API_KEY_HERE';
export default DS.RESTAdapter.extend({
host: `https://api.themoviedb.org/`,
namespace: '3',
pathForType() {
return `genre/movie/list?api_key=${apiKey}`;
},
});
Movie serializer
import DS from 'ember-data';
export default DS.RESTSerializer.extend({
normalizeResponse(store, primaryModelClass, payload, id, requestType) {
payload = { movies: payload.results };
return this._super(store, primaryModelClass, payload, id, requestType);
}
});
Genre serializer
import DS from 'ember-data';
export default DS.RESTSerializer.extend({
normalizeResponse(store, primaryModelClass, payload, id, requestType) {
payload = { genres: payload.genres };
return this._super(...arguments);
}
});
Movie model
import DS from 'ember-data';
const { attr, hasMany } = DS;
export default DS.Model.extend({
vote_count: attr('number'),
video: attr('boolean'),
vote_average: attr('number'),
title: attr('string'),
popularity: attr('number'),
poster_path: attr('string'),
original_language: attr('string'),
original_title: attr('string'),
genre_ids: attr(),
backdrop_path: attr('string'),
adult: attr('boolean'),
overview: attr('string'),
release_date: attr('date'),
});
Genre model
import DS from 'ember-data';
export default DS.Model.extend({
name: DS.attr('string'),
});
Route
import Route from '@ember/routing/route';
import RSVP from 'rsvp'
export default Route.extend({
model() {
return RSVP.hash({
movies: this.store.findAll('movie'),
genres: this.store.findAll('genre'),
});
},
});
Movie-listing Component
import Component from '@ember/component';
import { computed } from '@ember/object';
export default Component.extend({
movieGenreIds: computed('<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ff929089969a8cd1bf9a9e9c97d1989a918d9a">[email protected]</a>_ids', function() {
return this.movies.map(movie => movie.genre_ids).reduce((a, b) => [...a, ...b]);
}),
genresNames: computed('movieGenreIds', 'genres', 'movies', function() {
let names = [];
this.genres.map((genre) => {
this.movieGenreIds.forEach(movieGenreId => {
if (parseInt(genre.id) === movieGenreId) {
names.push(genre.name);
}
})
})
return names;
}),
});
Movies API (each movie from the results array has this structure):
{
"vote_count": 1092,

"vote_average": 6.7,
"title": "Venom",
"popularity": 505.173,
"poster_path": "\/2uNW4WbgBXL25BAbXGLnLqX71Sw.jpg",
"original_language": "en",
"original_title": "Venom",
"genre_ids": [27,878,28,53,35], // <-- I'm interested in this property
"backdrop_path": "\/VuukZLgaCrho2Ar8Scl9HtV3yD.jpg",
"adult": false,
"overview": "When Eddie Brock acquires the powers of a symbiote, he will have to release his alter-ego “Venom” to save his life.",
"release_date": "2018-10-03"
}
Genres API
"genres":[
{"id":28,"name":"Action"},
{"id":12,"name":"Adventure"},
{"id":16,"name":"Animation"},

Hbs Template (the expected result)

genres:
{{#each genresNames as |genre|}}
{{genre}} <!-- a list of genre names for this particular movie -->
