# Naming conflicts

#### Collection naming collisions

When importing collections to an admin panel, you may encounter naming collisions.

You can tackle them by renaming the collection that is causing issues.

There are two ways to rename collections: either provide a plain object which maps the old names to the new names, or a function which does the same.

Don't worry about leaving naming collisions: your development agent will warn you and crash at startup.

```php
use ForestAdmin\AgentPHP\Agent\Utils\Env;
use ForestAdmin\AgentPHP\DatasourceDoctrine\DoctrineDatasource;
use ForestAdmin\SymfonyForestAdmin\Service\ForestAgent;

return static function (ForestAgent $forestAgent) {
    // Rename the `customers` and `stores` collections.
    // Note that other collections won't be renamed.
    $forestAgent->addDatasource(
        new DoctrineDatasource(
            $forestAgent->getEntityManager(),
            ['url' => Env::get('DATABASE_URL')]
        ),
        [
            'rename' => [
                'Customer' => 'CustomerFromDoctrine',
                'Store' => 'StoreFromDoctrine',
            ],
        ]
    )
        ->build();
};
```

#### Field naming collisions

You can tackle them by renaming the fields that are causing issues too.

Use the [renameField method](/developer-guide-agents-php/agent-customization/fields/import-rename-remove.md#renaming-and-removing-fields-and-relations) to change the name inside your forestadmin-schema.
