Entity

[Ilqjx]

I use sea-orm-cli to generate entities, but I don't see Entity in the file.

pub use super::animal::Entity as Animal;

//! SeaORM Entity. Generated by sea-orm-codegen 0.6.0

use sea_orm::entity::prelude::*;

#[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
#[sea_orm(table_name = "animal")]
pub struct Model {
    #[sea_orm(primary_key, auto_increment = false)]
    pub id: i32,
    pub name: String,
}

#[derive(Copy, Clone, Debug, EnumIter)]
pub enum Relation {}

impl RelationTrait for Relation {
    fn def(&self) -> RelationDef {
        panic!("No RelationDef")
    }
}

impl ActiveModelBehavior for ActiveModel {}

Hey @Ilqjx, welcome! Good questions!

The DeriveEntityModel proc_macro actually defined Entity struct and implemented EntityName trait for you under the hood.

#[derive(Copy, Clone, Default, Debug, DeriveEntity)]
pub struct Entity;

impl EntityName for Entity {
    fn schema_name(&self) -> Option<&str> {
        None
    }

    fn table_name(&self) -> &str {
        "cake"
    }
}

Adapted from https://www.sea-ql.org/SeaORM/docs/generate-entity/expanded-entity-structure#entity

The source code of DeriveEntityModel proc_macro:

sea-orm/sea-orm-macros/src/derives/entity_model.rs

Lines 45 to 59 in 56cf4ea

	quote! {
	#[derive(Copy, Clone, Default, Debug, sea_orm::prelude::DeriveEntity)]
	pub struct Entity;
	#[automatically_derived]
	impl sea_orm::prelude::EntityName for Entity {
	fn schema_name(&self) -> Option<&str> {
	#schema_name
	}
	fn table_name(&self) -> &str {
	#table_name
	}
	}
	}
