Cakephp：如何使用 Twig 获取数据库表名列表

Question

I am creating a bake template using Twig for a cakePHP project. All what I want is to access the tables names of the database and their fields using twig to generate code based on these tables and fields.

I could easily access the tables names using (BUT THIS IS NOT WHAT I WANT)

use Cake\Datasource\ConnectionManager;

$db = ConnectionManager::get('default');
$collection = $db->getSchemaCollection();
$listTables = $collection->listTables(); 

I want to write something like that

{% set db = ConnectionManager.get('default') %}
{% set collection = db.getSchemaCollection() %}
{% set listTables = collection.listTables() %}

You can't use PHP Class or functions in twig directly. Also it's not best practice to use it this way.

Best solutions are:

1. Recommended: Put your login into the controller and pass the variable into the twig file. See passing variable section in the documentation here .

2. Another way you can do is write a Twig extension. A common structure is, writing a service with some utility functions, write a Twig extension as bridge to access the service from twig. The Twig extension will use the service and your controller can use the service too. Refer to this answer here .
