A Trait for overriding the ActiveModel behavior

Example

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

 // Use [DeriveEntity] to derive the EntityTrait automatically
#[derive(Copy, Clone, Default, Debug, DeriveEntity)]
pub struct Entity;

/// The [EntityName] describes the name of a table
impl EntityName for Entity {
    fn table_name(&self) -> &str {
        "cake"
    }
}

// Derive the ActiveModel
#[derive(Clone, Debug, PartialEq, DeriveModel, DeriveActiveModel)]
pub struct Model {
    pub id: i32,
    pub name: String,
}

impl ActiveModelBehavior for ActiveModel {}
