Suddenly, I can't get alembic (1.3.3?). alembic history does work, but my
most recent migration crashes with an enormous stack-trace (as usual):
here's my current pretty-simple migration script:
"""Citation datasource optional
Revision ID: f5a6e316ee8d
Revises: 2a181e783d96
Create Date: 2020-03-26 08:54:59.547135
"""
# revision identifiers, used by Alembic.
revision = 'f5a6e316ee8d'
down_revision = '2a181e783d96'
branch_labels = None
depends_on = None
from alembic import op
import sqlalchemy as sa
def upgrade():
op.alter_column('citation', 'id_datasource',
existing_Type=sa.INTEGER(),
nullable=True)
pass
def downgrade():
op.alter_column('citation', 'id_datasource',
existing_Type=sa.INTEGER(),
nullable=False)
pass
Here's the last stanza of the stack trace:
File
"/home/rschottland/.local/share/virtualenvs/astorb_db-u7fxujye/lib/python3.7/site-packages/sqlalchemy/sql/base.py",
line 289, in _validate_dialect_kwargs
"named <dialectname>_<argument>, got '%s'" % k
TypeError: Additional arguments should be named <dialectname>_<argument>,
got 'index'
The whole 69 line stack trace is attached.
This is the 30th migration for this database going back to 2015. Nothing
like this has occurred before. Could my alembic package be corrupted? The
previous (successful) igration was only 3 days ago.
Any thoughts on this would be appreciated.
