Interact with databases in Elixir apps using Ecto: define schemas with fields, associations, and embeds; build queries via Ecto.Query DSL for filtering, joining, aggregating, and preloading; validate, cast, and transform data with changesets before inserts and updates.
Use when validating and casting data with Ecto changesets including field validation, constraints, nested changesets, and data transformation. Use for ensuring data integrity before database operations.
Use when querying data with Ecto.Query DSL including where clauses, joins, aggregates, preloading, and query composition. Use for building flexible database queries in Elixir applications.
Use when defining data structures using Ecto schemas including fields, associations, embedded schemas, and schema metadata. Use for modeling domain data in Elixir applications.
Use when defining and working with Ecto schemas including field types, associations, and embedded schemas. Use when modeling database entities in Elixir.
