4.x - Missing datasource

[davidyell]

This is a (multiple allowed):

• bug

• enhancement

• feature-discussion (RFC)

• CakePHP Version: 4.0.0-alpha1

• Platform and Target: PHP 7.3.2 + nginx 1.15.9

Migrated from the main repo.

What you did

I created a new project using composer.
$ composer create-project cakephp/app:4.x-dev CakePHP4

What happened

When I visited my development url, I got an exception for a missing datasource.

Missing Datasource Configuration
Cake\Datasource\Exception\MissingDatasourceConfigException

Error: The datasource configuration debug_kit was not found in config/app.php.

What you expected to happen

I was expecting to see the CakePHP welcome page

How did you sidestep the issue?

I am using a domain name not in the safe list for DebutKit. So I had to force enable DebugKit, which fixed this issue.

For those looking to get past this issue, you could (but not recommended except for testing), disable the DebugKit being loaded alltogether.

In src\Application.php

public function bootstrap(): void
{
      $this->addPlugin('DebugKit'); <-- COMMENT OUT THIS

      // Call parent to load bootstrap from files.
      parent::bootstrap();

      if (PHP_SAPI === 'cli') {
          try {
              $this->addPlugin('Bake');
          } catch (MissingPluginException $e) {
              // Do not halt if the plugin is missing
          }
      }

      /*
       * Only try to load DebugKit in development mode
       * Debug Kit should not be installed on a production system
       */
      if (Configure::read('debug')) {
          $this->addPlugin('DebugKit'); <-- COMMENT OUT THIS
      }
  }

Again, not recommended. But at least the page shows up now.

This error message also appears to happen when the pdo_sqlite extension is not installed.

[THAMEY]

Installing the pdo_sqlite3 extension did resolve the issue for me. This should be noted in the documentation as requirement for the development environment.

[dereuromark]

How could this be asserted on install/usage? With a meaningful exception?
maybe someone can make a PR here?

[Manojkumarbashnet]

In app file:

.../config/app.php

in option "Datasources": create new sub option like this:

'debug_kit' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'port' => Dbport,
'username' => 'username',
'password' => password,
'database' => Dbname,
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => true,
'log' => false,'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
]

Save file app and refresh your website. Done.

This error message also appears to happen when the pdo_sqlite extension is not installed.

its works ty

[CHOUKI-Mouhssine]

in src/application.php
before line $this->addPlugin('DebugKit'); add this line Configure::write('DebugKit.forceEnable', true);

Example :

if (Configure::read('debug')) {
  Configure::write('DebugKit.forceEnable', true);
  $this->addPlugin('DebugKit');
}
