How do you pass in a dynamic form name in redux form?

Question

Im trying to use this code to pass a dynamic form name into reduxForm.

Here is the code that I found:

let FormAddress = compose(connect((state, props) => ({form: props.form})), reduxForm({destroyOnUnmount: false, asyncBlurFields: []}))(ValidationForm);

From this article: https://github.com/erikras/redux-form/issues/603#issuecomment-254271319

But I'm not really sure whats going on.

This is how I'm currently doing it:

const formName = 'shippingAddress';
const form = reduxForm({
  form: formName
});

export default connect(mapStateToProps)(CityStateZip);

But I would like to be able to pass it in using props, like this:

const formName = 'shippingAddress';
const form = reduxForm({
  form: props.form
  // validate
});

export default connect(mapStateToProps)(CityStateZip);

But when I try that, it complains that it doesnt know what props is - because I believe it's outside the scope of the function above.

Can someone help me?

Answer 1

The parent component which calling the FormAddress component should send the name of the form in props as props.form:

var formId="SomeId" <FormAddress form={formId} />  // and in your FormAddress component have  const form = reduxForm({   //no need to put form again here as we are sending form props. }); 

This works for me.

That snippet basically uses the compose function from redux library. Here's something you can try...

<FormAddress name="shippingAddress" />

So in your components/FormAddress.js file

import React from 'react'; import { compose } from 'redux'; import { connect } from 'react-redux'; import { reduxForm } from 'redux-form';  class FormAddress extends React.Component { ... }  const mapStateToProps = (state, ownProps) => {     return {         form: ownProps.name,         // other props...     } }  export default compose(     connect(mapStateToProps),     reduxForm({         //other redux-form options...     }) )(FormAddress); 

Hope this helps!
