O! My Models

O! My Models (omymodels) is a library to generate from SQL DDL Python Models for GinoORM (I hope to add several more ORMs in future).

You provide an input like:

CREATE TABLE "users" (
  "id" SERIAL PRIMARY KEY,
  "name" varchar,
  "created_at" timestamp,
  "updated_at" timestamp,
  "country_code" int,
  "default_language" int
);

CREATE TABLE "languages" (
  "id" int PRIMARY KEY,
  "code" varchar(2) NOT NULL,
  "name" varchar NOT NULL
);

and you will get output:

from gino import Gino


db = Gino()


class Users(db.Model):

    __tablename__ = 'users'

    id = db.Column(db.Integer(), autoincrement=True, primary_key=True)
    name = db.Column(db.String())
    created_at = db.Column(db.TIMESTAMP())
    updated_at = db.Column(db.TIMESTAMP())
    country_code = db.Column(db.Integer())
    default_language = db.Column(db.Integer())


class Languages(db.Model):

    __tablename__ = 'languages'

    id = db.Column(db.Integer(), primary_key=True)
    code = db.Column(db.String(2))
    name = db.Column(db.String())

How to install

pip install omymodels

How to use

From cli

omm path/to/your.ddl

# for example
omm tests/test_two_tables.sql

You can define target path where to save models with -t, –target flag:

# for example
omm tests/test_two_tables.sql -t test_path/test_models.py

Small library is used for parse DDL- https://github.com/xnuinside/simple-ddl-parser.

What to do if types not supported in O! My Models and you cannot wait until PR will be approved

First of all, to parse types correct from DDL to models - they must be in types mypping, for Gino it exitst in this file:

omymodels/gino/types.py types_mapping

If you need to use fast type that not exist in mapping - just do a path before call code with types_mapping.update()

for example:

from omymodels.gino import types  types_mapping
from omymodels import create_gino_models

types.types_mapping.update({'your_type_from_ddl': 'db.TypeInGino'})

ddl = "YOUR DDL with your custom your_type_from_ddl"

models = create_gino_models(ddl)
