ReactJS Router V4 history.push not working

Question

I have upgraded to React Router V4 and now struggling with the history.push method.

I have an index.js file:

import React from "react";
import { render } from "react-dom";
import { BrowserRouter, Route } from 'react-router-dom';
import createBrowserHistory from 'history/createBrowserHistory';

const history = createBrowserHistory();

import { Main} from "./components/Main";
import { About } from "./components/About";
import { Cars} from "./components/Cars";


class App extends React.Component {

render() {
    return (
        <BrowserRouter history={history}>

            <div>
                <Route path={"/"} component={Main} />
                <Route path={"/cars"} component={Cars}/>
                <Route path={"/about"} component={About}/>
            </div>
        </BrowserRouter>
    )
  }
}

render(<App/>, window.document.getElementById("app"));

And then I have another file, where I added a simple to return to a certain page which looks like this:

import React from "react";
import createBrowserHistory from 'history/createBrowserHistory';

const history = createBrowserHistory();

export class Cars extends React.Component {
  navigateBack() {
    history.push('/')
  }

  render() {
    return(
        <div>
            <h3>Overview of Cars</h3>
            <p>Model: </p>
            <button onClick={this.navigateBack} className="btn btn-primary">Back</button>
        </div>
    )
  }
}

So, I cannot figure out whats going wrong here. When I click on the button, the URL changes to / but thats all. Is there someone who can help me out?

EDIT

I found out, that it works when I do this:

this.props.history.push('/home')

and

<button onClick={this.onNavigateHome.bind(this)}

but it seems wrong somehow??

when I do

this.context.history.push('/home')

I get Cannot read property 'context' of null but why?? Is my <BrowserRouter> setup wrong??

Anyway, thanks for the help :)

Answer 1

You have to import {withRouter} from 'react-router-dom' and export your class in this way

export default withRouter(Cars)
