Using react-rte with redux-form
import React, { Component, PropTypes } from 'react'

@gsdean I am facing the same issue, if I use componentWillReceiveProps then cursor bounces around in the editor box. and serverside value is accessible only in nextProps.input.value and not in this.props.input.value. As componentWillReceiveProps always gets executed when value changes and set the state again and cursor bounce around.

did you had any solution for serverside data rendering with rte and redux-form?

@pbibalan your solution worked to compare the current state and next props. thank you!!

@pbibalan or anyone else, would you be able to provide a complete example of how you implemented and actually render the component in the form. I've literally spent 5 hrs on this now and am about to loose my mind.

Below attempt isn't recognized by redux-form. Initial value isn't available and value on submit...
<RichTextField name="overview" onChange={(value)=> value.toString('html')} />

Below attempt produces "Warning: Failed prop type: The prop onChange is marked as required in RichTextMarkdown, but its value is undefined"....

<Field
      component={RichTextField}
       type="text" 
       name="overview"
       onChange={(value)=> value.toString('html')}
/> 

I would really appreciate some help here.
Thanks!

@cantuket Hey,
recently got solved almost the same issue
this solution probably solve your's:

<Field
      component={RichTextField}
       type="text" 
       name="overview"
       input={{ value: whateverState || yourValue, onChange:(value)=> value.toString('html') }}
/>

there are the Shape proptype in subj gist:

  static propTypes = {
    input: PropTypes.shape({
      onChange: PropTypes.func.isRequired,
      value: PropTypes.string
    }).isRequired

you should pass input object to Field component with value and onChange
onChange can be your custom function:
i.e. myFunc =(val)=>{ doWhatEverWith(val)}
input={{ value: whateverState || yourValue, onChange:myFunc* }} *or this.myFunc if you defined it inside a class

None of the above work for me. The editor gets rendered but it is not being picked up in redux form.

I can't believe there is not a single example of the actual usage of this component.

Here is what I have:

RichTextEditor component:

import React, { Component, PropTypes } from 'react';
import RichTextEditor from 'react-rte';

class RichTextMarkdown extends Component {

    static propTypes = {
        input: PropTypes.shape({
            onChange: PropTypes.func.isRequired,
            value: PropTypes.string
        }).isRequired
    };
    constructor(props) {
        super(props);
        this.state = {
            value: this.props.input.value === '' ? RichTextEditor.createEmptyValue() : RichTextEditor.createValueFromString(this.props.input.value, 'html'),
        };
    }

    componentWillReceiveProps(nextProps) {
        if (nextProps.input.value !== this.state.value.toString('html')) {
            this.setState({
                value: nextProps.input.value ?
                    RichTextEditor.createValueFromString(nextProps.input.value, 'html') :
                    RichTextEditor.createEmptyValue()
            });
        }
    }

    onChange = (value) => {
        this.setState({ value });
        console.log(value.toString('html'));

        this.props.input.onChange(value);
    };

    render() {
        return (
            <RichTextEditor value={this.state.value} onChange={this.onChange} />
        );
    }
}

export default RichTextMarkdown;

Actual usage of the component:


import RTE from '../../../elements/RichTextMarkdown ';

// ... form omitted
 <Field
        component={RTE}
        type="text"
        name="comment_closing_page"
        value="test"
        input={{ value: 'TEST', onChange: value => value.toString('html') }} />

When I submit the form I get all of my other fields but I can't get hold of the values for the text editor. Any one know why this is?

Yep, I'm too.
So, I fixed it.

import React, {Component} from 'react';
import RichTextEditor from 'react-rte';

class RichTextMarkdown extends Component {

    constructor(props) {
        super(props);
        this.state = {
            value: this.props.input.value === '' ?
                RichTextEditor.createEmptyValue() :
                RichTextEditor.createValueFromString(this.props.input.value, 'html')
        };
    }

    componentWillReceiveProps(nextProps) {
        if (nextProps.input.value !== this.state.value.toString('html')) {
            this.setState({
                value: nextProps.input.value ?
                    RichTextEditor.createValueFromString(nextProps.input.value, 'html') :
                    RichTextEditor.createEmptyValue()
            });
        }
    }

    onChange(value) {
        const isTextChanged = this.state.value.toString('html') != value.toString('html');
        this.setState({value}, e => isTextChanged && this.props.input.onChange(value.toString('html')));
    };

    render() {
        return (
            <RichTextEditor value={this.state.value} onChange={this.onChange.bind(this)} />
        );
    }
}

export default RichTextMarkdown;

The problem is concurrent updates of component internal state and redux state. So, we need to put onChange dispatch in setState callback.

And you shouldn't specify input prop of Field, redux does it by itself. Use it like a simple input:

<Field name="description" component={RichTextMarkdown} />

A bit old posting, but could you explain why you put const wasSubmitting?

In my case, putting the following part into OP's code solved the initialization issue with asynchronous API calls.

componentWillReceiveProps(nextProps) {
    const isPristine = nextProps.meta.pristine; 

    if (nextProps.input.value && isPristine) {
      this.setState({
        value: this.RichTextEditor.createValueFromString(nextProps.input.value, 'markdown')
      });
    }
  }

based on this thread, I changed the componentWillRecieveProps in order to support React 16

sstur/react-rte#242 (comment)

componentWillReceiveProps(nextProps) {    
    this.state.value.setContentFromString(nextProps.value, "html");
}
