I'm following a course to update an item with React using Axios. I'm following the steps but I meet a problem with a function. When I click on the update button, it should redirect me to a page with the item form prepopulated but I got an error: TypeError: Cannot read property 'push' of undefined
See my code bellow with the handleUpdate function where the problem come from:
export default class ListBooks extends React.Component {
constructor(props) {
super(props);
this.state = { error: null, data: [], number: "", name: "" }
}
componentDidMount() {
Axios.get(process.env.REACT_APP_API_PATH_BOOKS)
.then(res => {
this.setState({ data: res.data });
})
.catch(errorThrown => {
this.setState({ error: errorThrown });
})
}
/**
* Use to delete a book by the number.
*/
handleDelete = (index) => {
const id = this.state.data[index].name
Axios.delete(process.env.REACT_APP_API_PATH_BOOKS + id)
.then(res => {
console.log(res);
console.log(res.data);
this.setState(prevState => ({ ...prevState, data: prevState.data.filter((book) => book.name !== id) }))
})
.catch(errorThrown => {
this.setState({ error: errorThrown });
})
}
handleUpdate = event => {
event.preventDefault();
this.props.history.push(`/admin/${this.state.number}/edit`);
console.log(this.props);
}
render() {
const { data } = this.state;
return (
<div>
<Container>
{data.map((books, index) =>
<div key={books.number}>
<ListGroup>
<ListGroup.Item disabled id={"book-admin" + data[index].number}>{books.number}. {books.name} {books.author}
</ListGroup.Item>
</ListGroup>
<Button variant="outline-warning" size="sm" className="btn-admin-change" onClick={this.handleUpdate}>Modifier</Button>
<Button variant="outline-danger" size="sm" className="btn-admin-change" onClick={() => this.handleDelete(index)}>Supprimer</Button>
</div>
)}
</Container>
</div>
)
}
}
I have never used this.props.history that way before and I don't really understand how it should work. Does anyone can explain me the problem here?
If you are using React-router Dom library for Routing below steps would help..
ie import { withRouter } from "react-router";
and wrap your component with withRouter(component_name);
Plz refer this link https://reactrouter.com/web/api/withRouter
looks like history props is missing so with above changes this should work
