Python SQLAlchemy Basics Introduction to SQLAlchemy Creating a Model

Base.metadata.create_all(engine)

would this work to create just the users table?

User.metadata.create_all(engine)

if not, how would I do that?

Best,

Jaeson

Hey jaesonshin, good question! According to the create_all docs, the parameter tables may list the tables to create. Default is None where all would be created.

Try Base.metadata.create_all(tables=[User])

Doc entry:

sqlalchemy.schema.MetaData.create_all(bind=None, tables=None, checkfirst=True)

Create all tables stored in this metadata.

Conditional by default, will not attempt to recreate tables already present in the target database.

Parameters

bind – A Connectable used to access the database; if None, uses the existing bind on this MetaData, if any.

tablesOptional list of Table objects, which is a subset of the total tables in the MetaData (others are ignored).

checkfirst – Defaults to True, don’t issue CREATEs for tables already present in the target database.

Oh.. I should have read the documentation more carefully... Thanks for putting up with this :)
