Alembic-自动生成空迁移

Alembic-自动生成空迁移

根据@zzzeek，在我将以下内容包括在内之后

env.py

，我就可以使用

--autogenerate

option

在

env.py

下面

run_migrations_online()

from configuration import appfrom core.expense.models import user # added my model herealembic_config = config.get_section(config.config_ini_section)alembic_config['sqlalchemy.url'] = app.config['SQLALCHEMY_DATAbase_URI']engine = engine_from_config(    alembic_config,    prefix='sqlalchemy.',    poolclass=pool.NullPool)

然后我跑

alembic revision --autogenerate -m "Added initial table"

了

def upgrade():    ### commands auto generated by Alembic - please adjust! ###    op.create_table('users',    sa.Column('uuid', sa.GUID(), nullable=False),    sa.Column('email', sa.String(), nullable=False),    sa.Column('password', sa.String(), nullable=False),    sa.Column('created_on', sa.DateTime(timezone=True), nullable=True),    sa.Column('last_login', sa.DateTime(timezone=True), nullable=True),    sa.PrimaryKeyConstraint('uuid'),    sa.UniqueConstraint('email'),    sa.UniqueConstraint('uuid')    )    ### end Alembic commands ###

谢谢迈克尔的所有帮助！
