Traits and Types

Entity​

A unit struct that implements EntityTrait representing a table in the database.

This trait contains the properties of an entity including

This trait also provides an API for CRUD actions

  • Select: find, find_*
  • Insert: insert, insert_*
  • Update: update, update_*
  • Delete: delete, delete_*

Column​

An enum that implements ColumnTrait representing all columns of the table and the column types and attributes.

It also implements

  • IdenStatic provides mapping to column identifier with static lifetime
  • Iterable allows SeaORM core to iterate over all column variants

Primary Key​

An enum that implements PrimaryKeyTrait representing the primary key. Each primary key variant must have a corresponding column variant.

It also implements

  • IdenStatic provides mapping to primary key identifier with static lifetime
  • Iterable allows SeaORM core to iterate over all primary key variants

Model​

A struct that implements ModelTrait storing the query result in memory. This is intended for readonly purposes, and it is stateless.

It also implements

Active Model​

A struct that implements ActiveModelTrait representing insert/update actions. This is intended to be edited and saved into database.

It also implements

Active Enum​

A enum that implements ActiveEnum representing value stored in database as a Rust enum variant.

Relation​

An enum that implements RelationTrait defined relations with other entities.

It also implements

  • Iterable allows SeaORM core to iterate over all relation variants

A generic trait, Related, defines join paths to help you query related entities together, especially helpful in many-to-many relations.

Linked​

A trait, Linked, defines complex join paths including chained relation, self referencing relation and multiple relations between two entities.
