问题
Have to create an edit Page editing a number of parameters on an instance of a'tale' resource.
However adding any element such as an MUI Card or even a div, is causing the app to freeze in various ways.
These are the approaches I have tried.
1) Adding a card component or placing my elements within a div for styling
export const EditorEditTale = (props) => {
return (
<Edit {...props} title="Tale Editor">
<SimpleForm >
<div>
<Image />
<TaleCardHeader props={ props } style={taleCardHeaderStyle.editor} />
</div>
</SimpleForm>
</Edit>
)
};
This is causing nothing to render.
Second approach, assuming that the record and basePath arent getting propagated to the children completely. Trying to use component like below.
const Input = ({record, basePath}) => {
return (
<div>
<LongTextInput source="taleText" />
</div>
)
}
This is causing the page to not render with everything in some kind of locking loop with the error - cannot read property touched of undefined.
How should I create a custom Edit page with a complex inputs and styling.
UPDATE: Been trying to write a custom form to substitute the SimpleForm component with no luck so far.

To create a custom form you can follow these steps:
- make an exact copy of SimpleForm to your project.
- rename SimpleForm to what you want.
- fix all the relative imports.
- test the new form until it works.
I made a minimum working form based on current master branch's SimpleForm
import React, { Children, Component } from 'react';
import PropTypes from 'prop-types';
import { reduxForm, Field } from 'redux-form';
import { connect } from 'react-redux';
import compose from 'recompose/compose';
import getDefaultValues from 'admin-on-rest/mui/form/getDefaultValues';
import FormField from 'admin-on-rest/mui/form/FormField';
import Toolbar from 'admin-on-rest/mui/form/Toolbar';
const formStyle = { padding: '0 1em 1em 1em' };
export class PostForm extends Component {
handleSubmitWithRedirect = (redirect = this.props.redirect) => this.props.handleSubmit(values => this.props.save(values, redirect));
render() {
const { children, invalid, record, resource, basePath, submitOnEnter, toolbar } = this.props;
return (
<form className="simple-form">
<Field name="name_of_a_field" component="input" />
{toolbar && React.cloneElement(toolbar, {
handleSubmitWithRedirect: this.handleSubmitWithRedirect,
invalid,
submitOnEnter,
})}
</form>
);
}
}
PostForm.propTypes = {
basePath: PropTypes.string,
children: PropTypes.node,
defaultValue: PropTypes.oneOfType([
PropTypes.object,
PropTypes.func,
]),
handleSubmit: PropTypes.func, // passed by redux-form
invalid: PropTypes.bool,
record: PropTypes.object,
resource: PropTypes.string,
redirect: PropTypes.oneOfType([
PropTypes.string,
PropTypes.bool,
]),
save: PropTypes.func, // the handler defined in the parent, which triggers the REST submission
submitOnEnter: PropTypes.bool,
toolbar: PropTypes.element,
validate: PropTypes.func,
};
PostForm.defaultProps = {
submitOnEnter: true,
toolbar: <Toolbar />,
};
const enhance = compose(
connect((state, props) => ({
initialValues: getDefaultValues(state, props),
})),
reduxForm({
form: 'record-form',
enableReinitialize: true,
}),
);
export default enhance(PostForm);
The above code works for AOR's example.
I hope this helps.
(import might be slightly different when you have AOR as npm dependency :
import getDefaultValues from 'admin-on-rest/lib/mui/form/getDefaultValues';
import FormField from 'admin-on-rest/lib/mui/form/FormField';
import Toolbar from 'admin-on-rest/lib/mui/form/Toolbar';
)

Documenting my final answer. You have to create a custom Redux Form. You can use AOR Input components straight. They come prewrapped for Redux Form.
import { Field, reduxForm } from 'redux-form';
import compose from 'recompose/compose';
import { connect } from 'react-redux';
class StyledForm extends Component {
// Newer version of aor needs this function defined and passed to save buttons. All props are being passed by parent List component.
handleSubmitWithRedirect = (redirect = this.props.redirect) => this.props.handleSubmit(values => this.props.save(values, redirect));
render() {
const { handleSubmit, invalid, record, resource, basePath } = this.props
return (<div>
<form onSubmit={handleSubmit} >
<Card >
<CardText >
//This component simply displays data, something not possible very easily with SimpleForm.
<HeaderComp basePath={basePath} record={record} />
<Field source="category_id"
optionText="categoryName"
reference="categories"
resource={resource}
record={record}
basePath={basePath}
name="NAME OF THE FIELD IN YOUR REDUX DATASTORE"
component={REFERENCEFIELDCOMP} />
//create complex div structures now.
<div >
<span>Tale</span>
<Field resource={resource} record={record} basePath={basePath} name="taleText" component={TextInput} />
</div>
</CardText >
<MuiToolbar>
<ToolbarGroup>
<SaveButton handleSubmitWithRedirect={this.handleSubmitWithRedirect}/>
//Add custom buttons with custom actions
<Field record={record} name="status" component={EditButtons} />
</ToolbarGroup>
</MuiToolbar>
</Card>
</form>
</div>)
}
};
const enhance = compose(
connect((state, props) => ({
initialValues: getDefaultValues(state, props),
})),
reduxForm({
form: 'record-form',
enableReinitialize: true,
}),
);
export default enhance(StyledForm);
You will have to either import or copy getDefaultValues from AOR in the node modules. I copied it into the file below.
import getDefaultValues from '../functions/getDefaultValues';
If you need a referenceField in your field. Then wrap it in a custom component like shown below
const DropDownSelector = ({optionText, ...props}) => {
return (
<ReferenceInput {...props} label="" >
<SelectInput optionText={optionText} />
</ReferenceInput>
)
}
