Derive Macro Model 

#[derive(Model)]
{
    // Attributes available to this derive:
    #[prax]
}

Derive macro for defining Prax models manually.

This derive macro allows you to define models in Rust code instead of using a .prax schema file. It generates the same query builder methods and type-safe operations.

Attributes

Unknown #[prax(...)] keys are rejected with a compile error.

Struct-level

• #[prax(table = "table_name")] - Map to a different table name
• #[prax(schema = "schema_name")] - NOT YET SUPPORTED: rejected with a compile error by the derive macro

Field-level

• #[prax(id)] - Mark as primary key
• #[prax(auto)] - Auto-increment field
• #[prax(unique)] - Unique constraint
• #[prax(default = "value")] - Database-side default value. The expression is applied by the database (e.g. via migrations), not by generated code; its presence makes the field optional in the generated CreateInput
• #[prax(column = "col_name")] - Map to different column
• #[prax(relation(...))] - Define relation

Example

#[derive(prax::Model)]
#[prax(table = "users")]
struct User {
    #[prax(id, auto)]
    id: i32,

    #[prax(unique)]
    email: String,

    #[prax(column = "display_name")]
    name: Option<String>,

    #[prax(default = "now()")]
    created_at: chrono::DateTime<chrono::Utc>,
}
