Model creation in Laravel - Step-by-Step Execution

Concept Flow - Model creation

Run artisan command

↓

Create Model file

↓

Model class created

↓

Add properties/methods

↓

Use model in app

The flow shows how running a command creates a model file, then you add details, and finally use it in your app.

Execution Sample

Laravel

php artisan make:model Product

// Model file created at app/Models/Product.php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Product extends Model {
  protected $fillable = ['name', 'price'];
}

This code creates a Product model with fillable fields name and price.

Execution Table

Step	Action	Result	File/Code Affected
1	Run 'php artisan make:model Product'	Model file 'Product.php' created	app/Models/Product.php
2	Open 'Product.php'	Model class 'Product' extends base Model	app/Models/Product.php
3	Add protected $fillable property	Allows mass assignment for 'name' and 'price'	app/Models/Product.php
4	Use Product model in controller	Can create/read/update/delete products	app/Http/Controllers/ProductController.php
5	Exit	Model ready for database interaction	N/A

💡 Model file created and ready to use in app

Variable Tracker

Variable	Start	After Step 3	Final
Product model	Not created	Created with fillable ['name', 'price']	Ready to use in app

Key Moments - 3 Insights

Why do we run 'php artisan make:model Product'?

This command creates the model file automatically, as shown in step 1 of the execution table.

What does the $fillable property do?

It allows mass assignment of specified fields, explained in step 3 of the execution table.

Where do we use the model after creation?

In controllers or other parts of the app to interact with the database, as in step 4.

Visual Quiz - 3 Questions

Look at the execution table, what happens at step 2?

A Database table is created

B Model class 'Product' is created extending base Model

C Model file is deleted

D Controller is generated

💡 Hint

Check the 'Result' column in step 2 of the execution table

At which step do we add the $fillable property?

A Step 4

B Step 1

C Step 3

D Step 5

💡 Hint

Look for the step mentioning 'Add protected $fillable property'

If we skip step 3, what would happen?

A Mass assignment will be blocked for all fields

B Model cannot be created

C Model file won't be created

D Controller won't work

💡 Hint

Step 3 explains $fillable allows mass assignment

Concept Snapshot

Model creation in Laravel:
- Run 'php artisan make:model ModelName' to create model file
- Model class extends base Model
- Use $fillable to allow mass assignment
- Use model in controllers for DB operations
- Model file saved in app/Models/

Full Transcript

To create a model in Laravel, you run the artisan command 'php artisan make:model Product'. This creates a file named Product.php in the app/Models directory. Inside this file, a class named Product extends the base Model class. You can add properties like $fillable to specify which fields can be mass assigned. After creating the model, you use it in your controllers or other parts of your app to interact with the database. This process helps organize your data logic cleanly.
