# Migrations/Tables

Commenter publishes following three migrations/tables. When migrating these tables, name collisions may occur if your project already uses the same table names as Commenter's tables. This page provides guidance on how to avoid such collisions.

| Migration Name                                                                                                                                   | Table Name |
| ------------------------------------------------------------------------------------------------------------------------------------------------ | ---------- |
| [create\_comments\_table](https://github.com/Lakshan-Madushanka/laravel-comments/blob/main/database/migrations/create_comments_table.php.stub)   | comments   |
| [create\_guests\_table](https://github.com/Lakshan-Madushanka/laravel-comments/blob/main/database/migrations/create_guests_table.php.stub)       | guests     |
| [create\_reactions\_table](https://github.com/Lakshan-Madushanka/laravel-comments/blob/main/database/migrations/create_reactions_table.php.stub) | reactions  |

Imagine your project already has a `comments` table, and you want to rename Commenter's `comments` table to `lakm_comments`.

#### Step-1

Create a model. 

```
php artisan make:model LakmComment
```

#### Step-2

Extend the model with the relevant base model. You can find the respective base models in the `config/commenter.php` configuration file. Then, define the table name in the `$table` property, with the public accessible.

```
 
 // config/commenter.php
 
 use LakM\Comments\Models\Comment;
 
 /**
   * Comment Model
   * Must extend base model LakM\Comments\Models\Comment
   */
  'model' => Comment::class,
```

```
// app/models/LakmComment.php

<?php

namespace App\Models;

use LakM\Comments\Models\Comment;

class LakmComment extends Comment
{
    public $table = 'lakm_comments'; // This line is a must have
}

?>
```

#### Step-3

Go to config/comment.php file and change the relevant model class.

```
// config/commenter.php
 
 use App\Models\LakmComment;
 
 /**
   * Comment Model
   * Must extend base model LakM\Comments\Models\Comment
   */
  'model' => LakmComment::class,
```

#### Step-4

Go to the relevant migration file and change the table name.

```
// database/migrations/{timestamp}_create_comments_table.php

 public function up(): void
    {
        Schema::create('lakm_comments', function (Blueprint $table) {
            ...
        });

        Schema::table('lakm_comments', function (Blueprint $table) {
            $table->foreign('reply_id')->references('id')->on('lakm_comments')->cascadeOnDelete();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('lakm_comments');
    }
```

{% hint style="info" %}
Though it is not necessary, it is recommended to rename the migration file as well. In the above example, it can be renamed to `{timestamp}_create_lakm_comments_table.php`.
{% endhint %}

## 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://lakm.gitbook.io/commenter/configuration/migrations-tables.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.
