Example Code

from typing import Optional

from sqlmodel import Field, Session, SQLModel, create_engine, select


class RealWordEN(SQLModel, table=True):
    id: int = Field(primary_key=True)
    string: str
    type: Optional[str]
    number: Optional[str]
    tense: Optional[str]

    __tablename__ = "real_words_EN"


engine = create_engine("mysql+mysql://root:root@localhost:8889/words", echo=True)
# engine = create_engine("mysql://root:root@localhost:8889/words", echo=True)


with Session(engine) as session:
    statement = select(RealWordEN)
    words = session.exec(statement)

Description

I’ve been trying to interact with an existing MySQL DB. When I try the run this code I get the following error message:

raise exc.NoSuchModuleError(
sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:mysql.mysql

I also tried with th DB URL format: engine = create_engine("mysql://root:root@localhost:8889/words", echo=True). In that case, I get a different error message:

ModuleNotFoundError: No module named 'MySQLdb'

Is there some MySQL connection Python module that needs to be installed as well along sqlmodel? I’ve been trying with installing pymysql, aiomysql, with similar errors.

For the record, I didn’t mean it’s not being actively maintained as such, but its only at ver 0.0.6, with 64 open pull requests. Some fix simple bugs and have been sat there for 6 months without anyone looking at them. And there hasn’t been a release in 4 months. And you are right that it does seem to be in a pretty good spot.

For what its worth SQLModel does make the whole FastAPI + SQLAlchemy thing a lot nicer, but you can’t side step really knowing SQLAlchemy. The alternative is to define separate Pydantic and SQLAlchemy models for basically the same thing. Also the type hinting in this library is really nice.

I’d say stick with it

Hello,

I just tried to recreate your issue. It seems like mysqlclient is the only connector that I can get to work using:

engine = create_engine("mysql://root:root@localhost:8889/words", echo=True)

Unfortunately, I couldn’t find any recommended connector in the documentation.
