Eloquent Relationships

When to use

• The user has slow pages or a flood of queries from accessing a relationship inside a loop and needs to eager load with with(), load(), or loadMissing().
• The user needs a many-to-many association through a pivot table — users and roles, posts and tags — with belongsToMany and optional pivot columns.
• The user needs to relate two Eloquent models — a user has many posts, a post belongs to a user, an order has one invoice.
• The user needs one model (comments, images) to belong to several parent types and reaches for morphTo/morphMany polymorphic relations.
