Expand description

Available attributes on a column (struct field)

Fields§

§primary_key: Flag§insertable_primary_key: Flag

Marks a primary key, but includes it in the Insert struct.

§default: Flag

Specifies that a default exists at the database level.

§default_value: Option<LitStr>

Specify a default value on the Rust side.

§join_table: Option<LitStr>

Example: pub struct User { pub org_id: i32, #[ormlite(join_table = “user_role”)] pub roles: Join<Vec>, }

§foreign_field: Option<Path>

Example: pub struct User { pub id: i32, #[ormlite(foreign_field = Post::author_id)] pub posts: Join<Vec>, }

pub struct Post { pub id: i32, pub author_id: i32, }

§column: Option<LitStr>

The name of the column in the database. Defaults to the field name.

Required for many to one joins. Example: pub struct User { #[ormlite(column = “organization_id”)] pub organization: Join, }

§skip: Flag

Skip serializing this field to/from the database. Note the field must implement Default.

§json: Flag
