How do I add checkboxes to admin-on-rest admin on rest create form and post the checkbox value to backend - admin-on-rest

Question

I have added the material-ui/Checkbox component in admin-on-rest create form with source attribute. But after I click save button, I could not see the checkbox value in posted data.
But I can see 'title' and 'body' fields value in posted data. Can someone please tell, Why this code is not working?
Here is my sample code:
export const PostCreate = (props) => (
<Create {...props} >
<SimpleForm>
<TextInput source="title" />
<LongTextInput source="body" />
<Checkbox
label="Label on the left"
labelPosition="left"
source="test"
value="yes"
/>
</SimpleForm></Create>
);

Answer 1

Sure Checkbox is not a react-on-admin component. Please use BooleanInput

Answer 2

The BooleanInput.js module from rect-admin, Switch is replaced with Checkbox:
import React, { Component } from 'react'
import PropTypes from 'prop-types'
import FormControlLabel from '#material-ui/core/FormControlLabel'
import FormGroup from '#material-ui/core/FormGroup'
import Checkbox from '#material-ui/core/Checkbox'
import { addField, FieldTitle } from 'ra-core'
const sanitizeRestProps = ({
alwaysOn,
basePath,
component,
defaultValue,
formClassName,
initializeForm,
input,
isRequired,
label,
locale,
meta,
options,
optionText,
optionValue,
record,
resource,
allowEmpty,
source,
textAlign,
translate,
translateChoice,
...rest
}) => rest
export class CheckboxInput extends Component {
handleChange = (event, value) => {
this.props.input.onChange(value)
}
render() {
const {
className,
input,
isRequired,
label,
source,
resource,
options,
...rest
} = this.props
return (
<FormGroup className={className} {...sanitizeRestProps(rest)}>
<FormControlLabel
control={
<Checkbox
color="primary"
checked={!!input.value}
onChange={this.handleChange}
{...options}
/>
}
label={
<FieldTitle
label={label}
source={source}
resource={resource}
isRequired={isRequired}
/>
}
/>
</FormGroup>
)
}
}
CheckboxInput.propTypes = {
className: PropTypes.string,
input: PropTypes.object,
isRequired: PropTypes.bool,
label: PropTypes.string,
resource: PropTypes.string,
source: PropTypes.string,
options: PropTypes.object,
}
CheckboxInput.defaultProps = {
options: {},
}
export default addField(CheckboxInput)
