support type alias

[huang12zheng]

Motivation

I want to def some native type with alias name.

type FirstName = String;
type LastName = String;
type ActorId = u32;

But, it get a error,

seaography::macros::Filter,
  |     ^^^^^^^^^^^^^^^^^^^^^^^^^^ could not find `sea_orm_active_enums` in `entities` 

Proposed Solutions

source from

let filter_item = if default_filters.contains(&type_literal.as_str())
                || type_literal.starts_with("Vec")
            {
                quote! {
                    seaography::TypeFilter<#ty>
                }
            } else {
                let ident = format_ident!("{}EnumFilter", type_literal);
                quote! {
                    crate::entities::sea_orm_active_enums::#ident
                }
            };

1. It may need to check whether the identifier is an enum

2. Generate a schema that uses ident directly

Additional Information

maybe the same as #76

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

#[derive(
    Clone,
    Debug,
    PartialEq,
    DeriveEntityModel,
    async_graphql::SimpleObject,
    seaography::macros::Filter, // could not find `sea_orm_active_enums` in `entities`
    // pub struct Filter {
    //     pub or: Option<Vec<Box<Filter>>>,
    //     pub and: Option<Vec<Box<Filter>>>,
    //     actor_id: Option<crate::entities::sea_orm_active_enums::ActorIdEnumFilter>,
    //     first_name: Option<crate::entities::sea_orm_active_enums::FirstNameEnumFilter>,
    //     last_name: Option<crate::entities::sea_orm_active_enums::LastNameEnumFilter>,
    //     last_update: Option<seaography::TypeFilter<DateTimeUtc>>,
    // }
)]
#[sea_orm(table_name = "actor")]
#[graphql(complex)]
#[graphql(name = "Actor")]
// pub struct Model {
//     #[sea_orm(primary_key)]
//     pub actor_id: i32,
//     pub first_name: String,
//     pub last_name: String,
//     pub last_update: DateTimeUtc,
// }
pub struct Model {
    #[sea_orm(primary_key)]
    pub actor_id: ActorId,
    pub first_name: FirstName,
    pub last_name: LastName,
    pub last_update: DateTimeUtc,
}

type FirstName = String;
type LastName = String;
type ActorId = u32;

#[derive(Copy, Clone, Debug, EnumIter, DeriveRelation, seaography::macros::RelationsCompact)]
pub enum Relation {}

impl ActiveModelBehavior for ActiveModel {}

Hey @huang12zheng, sorry for the delay and thanks for the report!!

Actually, I think this proposal can solve this issue. Which is more generic and foolproof:

• A generic filter for any types and database enums #87
