React setState fetch API - reactjs

Question

I am starting to learn React and creating my second project at the moment. I am trying to usi MovieDb API to create a movie search app. Everything is fine when I get the initial list of movies. But onClick on each of the list items I want to show the details of each movie. I have created a few apps like this using vanilla JS and traditional XHR call. This time I am using fetch API which seems straightforward ans simply to use, however when I map through response data to get id of each movie in order to retrieve details separately for each of them I get the full list of details for all the items, which is not the desired effect. I put the list of objects into an array, because after setState in map I was only getting the details for the last element. I know that I am probably doing something wrong within the API call but it might as well be my whole REACT code. I would appreciate any help.
My code
App.js
import React, { Component } from 'react';
import SearchInput from './Components/SearchInput'
import './App.css';
class App extends Component {
constructor(props) {
super(props);
this.state =
{
value: '',
showComponent: false,
results: [],
images: {},
};
this.handleSubmit = this.handleSubmit.bind(this);
this.handleOnChange = this.handleOnChange.bind(this);
this.getImages = this.getImages.bind(this);
this.getData = this.getData.bind(this);
}
ComponentWillMount() {
this.getImages();
this.getData();
}
getImages(d) {
let request = 'https://api.themoviedb.org/3/configuration?api_key=70790634913a5fad270423eb23e97259'
fetch(request)
.then((response) => {
return response.json();
}).then((data) => {
this.setState({
images: data.images
});
});
}
getData() {
let request = new Request('https://api.themoviedb.org/3/search/movie?api_key=70790634913a5fad270423eb23e97259&query='+this.state.value+'');
fetch(request)
.then((response) => {
return response.json();
}).then((data) => {
this.setState({
results: data.results
});
});
}
handleOnChange(e) {
this.setState({value: e.target.value})
}
handleSubmit(e) {
e.preventDefault();
this.getImages();
this.setState({showComponent: true});
this.getData();
}
render() {
return (
<SearchInput handleSubmit={this.handleSubmit} handleOnChange={this.handleOnChange} results={this.state.results} images={this.state.images} value={this.state.value} showComponent={this.state.showComponent}/>
);
}
}
export default App;
SearchInput.js
import React, {Component} from 'react';
import MoviesList from './MoviesList';
class SearchInput extends Component {
render() {
return(
<div className='container'>
<form id='search-form' onSubmit={this.props.handleSubmit}>
<input value={this.props.value} onChange={this.props.handleOnChange} type='text' placeholder='Search movies, tv shows...' name='search-field' id='search-field' />
<button type='submit'>Search</button>
</form>
<ul>
{this.props.showComponent ?
<MoviesList value={this.props.value} results={this.props.results} images={this.props.images}/> : null
}
</ul>
</div>
)
}
}
export default SearchInput;
This is the component where I try to fetch details data
MovieList.js
import React, { Component } from 'react';
import MovieDetails from './MovieDetails';
let details = [];
class MoviesList extends Component {
constructor(props) {
super(props);
this.state = {
showComponent: false,
details: []
}
this.showDetails = this.showDetails.bind(this);
this.getDetails = this.getDetails.bind(this);
}
componentDidMount() {
this.getDetails();
}
getDetails() {
let request = new Request('https://api.themoviedb.org/3/search/movie?api_key=70790634913a5fad270423eb23e97259&query='+this.props.value+'');
fetch(request)
.then((response) => {
return response.json();
}).then((data) => {
data.results.forEach((result, i) => {
let url = 'https://api.themoviedb.org/3/movie/'+ result.id +'?api_key=70790634913a5fad270423eb23e97259&append_to_response=videos,images';
return fetch(url)
.then((response) => {
return response.json();
}).then((data) => {
details.push(data)
this.setState({details: details});
});
});
console.log(details);
});
}
showDetails(id) {
this.setState({showComponent: true}, () => {
console.log(this.state.details)
});
console.log(this.props.results)
}
render() {
let results;
let images = this.props.images;
results = this.props.results.map((result, index) => {
return(
<li ref={result.id} id={result.id} key={result.id} onClick={this.showDetails}>
{result.title}{result.id}
<img src={images.base_url +`${images.poster_sizes?images.poster_sizes[0]: 'err'}` + result.backdrop_path} alt=''/>
</li>
)
});
return (
<div>
{results}
<div>
{this.state.showComponent ? <MovieDetails details={this.state.details} results={this.props.results}/> : null}
</div>
</div>
)
}
}
export default MoviesList;
MovieDetails.js
import React, { Component } from 'react';
class MovieDetails extends Component {
render() {
let details;
details = this.props.details.map((detail,index) => {
if (this.props.results[index].id === detail.id) {
return(
<div key={detail.id}>
{this.props.results[index].id} {detail.id}
</div>
)} else {
console.log('err')
}
});
return(
<ul>
{details}
</ul>
)
}
}
export default MovieDetails;

Answer 1

Theres a lot going on here...
//Here you would attach an onclick listener and would fire your "get details about this specific movie function" sending through either, the id, or full result if you wish.
//Then you getDetails, would need to take an argument, (the id) which you could use to fetch one movie.
getDetails(id){
fetch(id)
displayresults, profit
}
results = this.props.results.map((result, index) => {
return(
<li onClick={() => this.getDetails(result.id) ref={result.id} id={result.id} key={result.id} onClick={this.showDetails}>
{result.title}{result.id}
<img src={images.base_url +`${images.poster_sizes?images.poster_sizes[0]: 'err'}` + result.backdrop_path} alt=''/>
</li>
)
});

Thanks for all the answers but I have actually maanged to sort it out with a bit of help from a friend. In my MovieList I returned a new Component called Movie for each component and there I make a call to API fro movie details using each of the movie details from my map function in MovieList component
Movielist
import React, { Component } from 'react';
import Movie from './Movie';
class MoviesList extends Component {
render() {
let results;
if(this.props.results) {
results = this.props.results.map((result, index) => {
return(
<Movie key={result.id} result={result} images={this.props.images}/>
)
});
}
return (
<div>
{results}
</div>
)
}
}
export default MoviesList;
Movie.js
import React, { Component } from 'react';
import MovieDetails from './MovieDetails';
class Movie extends Component {
constructor(props) {
super(props);
this.state = {
showComponent: false,
details: []
}
this.showDetails = this.showDetails.bind(this);
this.getDetails = this.getDetails.bind(this);
}
componentDidMount() {
this.getDetails();
}
getDetails() {
let request = new Request('https://api.themoviedb.org/3/search/movie?api_key=70790634913a5fad270423eb23e97259&query='+this.props.value+'');
fetch(request)
.then((response) => {
return response.json();
}).then((data) => {
let url = 'https://api.themoviedb.org/3/movie/'+ this.props.result.id +'?api_key=70790634913a5fad270423eb23e97259&append_to_response=videos,images';
return fetch(url)
}).then((response) => {
return response.json();
}).then((data) => {
this.setState({details: data});
});
}
showDetails(id) {
this.setState({showComponent: true}, () => {
console.log(this.state.details)
});
}
render() {
return(
<li ref={this.props.result.id} id={this.props.result.id} key={this.props.result.id} onClick={this.showDetails}>
{this.props.result.title}
<img src={this.props.images.base_url +`${this.props.images.poster_sizes?this.props.images.poster_sizes[0]: 'err'}` + this.props.result.backdrop_path} alt=''/>
{this.state.showComponent ? <MovieDetails details={this.state.details}/> : null}
</li>
)
}
}
export default Movie;
