TextColumn/TextEntry Relation with links

[dharen008]

I've extended the TextColumn/TextEntry and added a feature to include a link if the data has a resource. Hopefully, this can be added to Filament as a default option, but feel free to use it in the meantime.

`<?php

namespace App\Extended\Tables\Columns;

use Filament\Tables\Columns\TextColumn as ExtendedTextColumn;
use Illuminate\Support\HtmlString;

class TextColumn extends ExtendedTextColumn
{

protected function setUp(): void
{
	parent::setUp();
}

// You should remove the clickable row by using recordUrl(null) or recordAction(null).
// If you don't use recordUrl(null), the resource will have an HTML issue.
public function listWithLinks( $resourceClass = null, $page = 'view', $columnText = 'name', $shouldOpenInNewTab = true )
{
	$newTab = !$shouldOpenInNewTab ?: ' target="_blank"';

	return $this->formatStateUsing( function ( $state, $record ) use ( $resourceClass, $page, $columnText, $newTab ) {
		$relationName	= explode( '.', $this->name )[ 0 ];
		$getCollection	= $record->$relationName;

		if ( $this->isBadge() || $this->isListWithLineBreaks() ) {
			$getModel		= $getCollection->where( 'name', $state )->first();
			$resourceClass	= $resourceClass ?: self::getModelResource( $getModel );

			// Check if the resource class exists
			if ( class_exists( $resourceClass ) ) {
				// Generate the URL for the "view" action on the resource
				$url = $resourceClass::getUrl( $page, [ $getModel->id ] );

				// You can use the generated URL in your link
				return new HtmlString( "<a href='{$url}'{$newTab}>{$getModel->$columnText}</a>" );
			} else {
				// Handle if the resource class does not exist
				return new HtmlString( "<span>{$getModel->$columnText}</span>" );
			}
		} else {
			$output = '';

			// Loop through the related records
			foreach ( $getCollection as $relation ) {
				$resourceClass = self::getModelResource( $relation );

				// Check if the resource class exists for the related model
				if ( class_exists( $resourceClass ) ) {
					// Generate the URL for the "view" page of the relation
					$url = $resourceClass::getUrl( $page, [ $relation->id ] );
					
					// Append the link for the relation to the output
					$output .= new HtmlString( "<a href='{$url}'{$newTab}>{$relation->$columnText}</a>, ");
				} else {
					// If the related resource does not exist, just show the relation's name
					$output .= new HtmlString( "<span>{$relation->$columnText}</span>, ");
				}
			}

			return new HtmlString( $output );
		}
	} );
}

public function getModelResource( $model )
{
	$modelClass = get_class( $model );
	return "App\\Filament\\Resources\\" . class_basename( $modelClass ) . 'Resource';
}
