In v12.0.0 classic editor build (latest version), the code structure changed. I don't know how to modify the following code

[gongzhiq]

hello，How to modify this code so that it can run

import { downcastElementToElement, downcastAttributeToAttribute } from '@ckeditor/ckeditor5-engine/src/conversion/downcast-converters';
import { upcastElementToElement, upcastAttributeToAttribute  } from '@ckeditor/ckeditor5-engine/src/conversion/upcast-converters';

class myWidget extends Plugin {
    init() {
        const editor = this.editor;
        const model = editor.model;
		
        model.schema.register( 'myWidget', {
            inheritAllFrom: '$block',
            isObject: true
        } );
		
		model.schema.register( 'myWidget2', {
            inheritAllFrom: '$block',
			allowIn: 'myWidget',
            isObject: true
        } );


        editor.conversion.for( 'dataDowncast' )
            .add( downcastElementToElement( {
                model: 'myWidget',
                view: ( modelItem, writer ) => {
                    return writer.createContainerElement( 'div', { class: "note_bookinfo_name" } );
                }
            } ) );

        editor.conversion.for( 'editingDowncast' )
            .add( downcastElementToElement( {
                model: 'myWidget',
                view: ( modelItem, writer ) => {
                    const div = writer.createContainerElement( 'div', { class: "note_bookinfo_name"} );
                    return toWidget( div, writer);
                }
            } ) );

        editor.conversion.for( 'upcast' )
            .add( upcastElementToElement( {
                view: {
                    name: 'div',
                    key: 'class'
                },
                model: 'myWidget'
            } ) );
			
	    editor.conversion.for( 'dataDowncast' )
            .add( downcastElementToElement( {
                model: 'myWidget2',
                view: ( modelItem, writer ) => {
                    return writer.createContainerElement( 'objectid', { class: "note_bookinfo_id" } );
                }
            } ) );

        editor.conversion.for( 'editingDowncast' )
            .add( downcastElementToElement( {
                model: 'myWidget2',
                view: ( modelItem, writer ) => {
                    const objectid = writer.createContainerElement( 'objectid', { class: "note_bookinfo_id"} );
                    return toWidget( objectid, writer);
                }
            } ) );

        editor.conversion.for( 'upcast' )
            .add( upcastElementToElement( {
                view: {
                    name: 'objectid',
                    key: 'class'
                },
                model: 'myWidget2'
            } ) );
    }
}

Thank you very much

Hi!

Sorry for the trouble with the API change. It's a change for good so, though, so I'm sure it was worth it :)

With every release we publish a changelog which describes all breaking changes. This time wasn't different – v12.0.0. In this changelog you will find a Migration guide with information how to update your code.
