React Router Redirect Conditional - reactjs

Question

I'm trying to make a button that only redirects the user to a new page after validation is completed correctly.
Is there a way of doing something like this?
How to I get a Route to be activated inside of a class method?
import validator from './validator';
class Example {
constructor(props) {
super(props)
this.saveAndContinue = thos.saveAndContinue.bind(this)
}
saveAndContinue () {
var valid = validator.validate(this.props.form)
if (valid) {
axios.post('/path')
<Redirect to='/other_tab'>
} else {
validator.showErrors()
}
}
render() {
<button onClick={this.saveAndContinue}>Save and Continue</button>
}
}

Answer 1

As discussed you should have access to the history object via this.props.history as described here.
If you look into the push function this will redirect you to any route you need.
For example:
// Use push, replace, and go to navigate around.
this.props.history.push('/home', { some: 'state' })

Like Purgatory said you can do it without using <Redirect />, but otherwise you could make your component a stateful component and then do a conditional render like so
render() {
!this.state.redirect ?
<button onClick={this.saveAndContinue}>Save and Continue</button> :
<Redirect to='/other_tab'>
}
And let the saveAndContinue() change the component state.
saveAndContinue () {
var valid = validator.validate(this.props.form)
if (valid) {
axios.post('/path')
this.setState({redirect: true});
} else {
validator.showErrors()
}
}
When the state changes it would cause a re-render and this time the <Redirect /> would be rendered.
Note: I didn't actually run this code snippet, so it may contain (hopefully minor) errors.
