CLI generate enum with numeric like variants

[billy1624]

PR Info

• Closes sea-orm-cli: Ident cannot be a number #579

Fixes

• When generating ActiveEnum with number like variants. Those variants can't be formatted as Rust identifier. This can be fixed by add an _ before the number like variants.

The SQL of Enum type.

create type tea as enum ('1', '2');

The generated ActiveEnum

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

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

#[derive(Debug, Clone, PartialEq, EnumIter, DeriveActiveEnum)]
#[sea_orm(rs_type = "String", db_type = "Enum", enum_name = "tea")]
pub enum Tea {
    #[sea_orm(string_value = "1")]
    _1,
    #[sea_orm(string_value = "2")]
    _2,
}

Hey @yb3616, you can try it by cloning the branch. Then, cd into sea-orm/sea-orm-cli folder. Finally, run the sea-orm-cli with the following command

cargo run -- generate entity --database-url postgres://root:root@localhost/active_enum_tests -o output_folder

@yb3616 what is your use case for this? Isn't it strange to use a enum with numeric variants?

#1172 may be 'starts_with numeric'?
