You can paste authenticity_token
into react component.
Using gem react-rails
= react_component 'Form', authenticity_token: form_authenticity_token
form_authenticity_token
is the rails helper.
So you can paste it into your form.
<form role="form" accept-charset="UTF-8" action='/action' method='post'>
...
<input type="hidden" name="authenticity_token" value={this.props.authenticity_token} />
...
</form>
It’s not the best solution. I would be happy if someone will tell a better solution.
