Laravel Eloquent Relationships | An Intro

Did you know that Laravel Eloquent is a tool that helps us work with databases in a simple way?

It helps us to define relationships between tables in the database and easily access data. Furthermore, relationships help us connect different tables and perform operations on them without writing complex queries.

Let’s take a look at some of the different types of relationships we can define in Eloquent:

• One-to-One Relationship:

  This is like having a special connection between two tables. For example, if we have a table for users and another table for their profiles, each user can have only one profile. It’s like a one-to-one connection.
• One-to-Many Relationship:

  In this case, one record in a table can be related to multiple records in another table. For example, if we have a table for blog posts and another table for comments, each post can have many comments. It’s like a one-to-many connection.
• Many-to-Many Relationship:

  This is when both tables can have multiple related records. For instance, if we have a table for users and another table for roles, one user can have multiple roles, and one role can be assigned to multiple users. It’s like a many-to-many connection.
• Has-Many-Through Relationship:

  It allows us to connect two tables indirectly through a third table. For example, if we have a table for countries, a table for posts, and a table for users, we can use this relationship to get all posts written by users from a specific country.
• Polymorphic Relationships:

  This allows a model to belong to different types of models. For instance, if we have a table for comments, they can belong to either a blog post or a video. It’s like a versatile relationship.
