trulens.core.database.migrations.env¶
Functions¶
run_migrations_offline() -> None
Run migrations in 'offline' mode.
This configures the context with just a URL and not an Engine, though an Engine is acceptable here as well. By skipping the Engine creation we don't even need a DBAPI to be available.
Calls to context.execute() here emit the given string to the script output.
run_migrations_online() -> None
Run migrations in 'online' mode.
In this scenario we need to create an Engine and associate a connection with the context.
