How do embedded schemas differ from regular schemas?

Regular schemas map to specific database tables, while embedded schemas are used for data structures that are typically stored as JSON within a parent record's field.

When should I use virtual fields?

Use virtual fields for data needed during processing but not stored in the database, such as password confirmation fields or calculated full names.

Can I use this for many-to-many relationships?

Yes, this skill provides the correct syntax and patterns for defining many_to_many associations using join tables and join_through options.

What is an Ecto schema?

An Ecto schema maps a database table or a data source to an Elixir struct, defining the fields, types, and constraints for your application's data layer.

Does this skill help with data validation?

Yes, it includes patterns for defining changesets within schema modules to validate required fields, formats, and numeric constraints.

データベース管理

Models database entities in Elixir by defining Ecto schemas, complex associations, and embedded data structures.

概要

Ecto Schema Modeling provides specialized guidance for architecting the data layer of Elixir and Phoenix applications. It enables developers to define robust database entities with precise field types, manage complex relational associations like many-to-many, and utilize embedded schemas for flexible JSON storage. By incorporating best practices for virtual fields and changeset validations, this skill ensures that your application's data structures are type-safe, maintainable, and aligned with professional Elixir development standards.
