  3. Integrating Seeding and Factories:
    • Combining seeding and factories to create complex data scenarios
    • Leveraging factory states and relationships to generate more realistic data
  4. Automated Testing with Seeding and Factories:
    • Utilizing seeding and factories in your automated testing suite
    • Ensuring consistent data across different test environments

By the end of this section, you’ll be equipped with the knowledge to effectively seed your database with test data and maintain the integrity of your application’s data throughout the development lifecycle.

Section 5: Working with Database Relationships

One of the powerful features of the Laravel database is the ability to define and manage relationships between your database tables. In this section, we’ll delve into the different types of relationships and how to implement them in your Laravel applications.

  1. One-to-One Relationships:
    • Defining and implementing one-to-one relationships
    • Accessing related data using Eloquent’s relationship methods
  2. One-to-Many Relationships:
    • Establishing and working with one-to-many relationships
