# Naming Method

`namingMethod()` method in the `Attachment` class allows users to choose one of the three available naming methods for file uploads. These methods are:

1. `HASH_FILE`: This method generates a unique name for the uploaded file based on the file's contents using the `md5` algorithm.
2. `TIME`: This method generates a name for the uploaded file based on the current timestamp.
3. `SLUG`: This method generates a name for the uploaded file using a slug representation of the original filename.

Users can set the naming method for an attachment by passing one of these options as a parameter to the `namingMethod()` method. For example:

```php
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Mostafaznv\Larupload\Enums\LaruploadNamingMethod;
use Mostafaznv\Larupload\Storage\Attachment;
use Mostafaznv\Larupload\Traits\Larupload;

class Media extends Model
{
    use Larupload;

    public function attachments(): array
    {
        return [
            Attachment::make('file')
                ->namingMethod(LaruploadNamingMethod::HASH_FILE)
        ];
    }
}
```

This will set the naming method for the attachment to the `HASH_FILE` method.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mostafaznv.gitbook.io/larupload/advanced-usage/attachment/naming-method.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
