this link http://alembic.zzzcomputing.com/en/latest/ops.html#alembic.operations.Operations.create_index suggest I can pass dialect specific options def upgrade(): op.drop_index('ix_taggable_resource_value', 'taggable') op.create_index('ix_taggable_resource_value', 'taggable', [ 'resource_value' ], postgresql_ops = { 'resource_value', 'text_pattern_ops' } ) NFO [alembic.migration] Running upgrade 2cbd9f4d11af -> 318381ec60ba, indexes 4 deletes Traceback (most recent call last): File "/home/kgk/Envs/bq059/bin/alembic", line 11, in <module> sys.exit(main()) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/config.py", line 298, in main CommandLine(prog=prog).main(argv=argv) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/config.py", line 293, in main self.run_cmd(cfg, options) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/config.py", line 279, in run_cmd **dict((k, getattr(options, k)) for k in kwarg) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/command.py", line 124, in upgrade script.run_env() File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/script.py", line 199, in run_env util.load_python_file(self.dir, 'env.py') File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/util.py", line 205, in load_python_file module = load_module_py(module_id, path) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/compat.py", line 58, in load_module_py mod = imp.load_source(module_id, path, fp) File "./migrations/env.py", line 76, in <module> run_migrations_online() File "./migrations/env.py", line 69, in run_migrations_online context.run_migrations() File "<string>", line 7, in run_migrations File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/environment.py", line 681, in run_migrations self.get_context().run_migrations(**kw) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/migration.py", line 225, in run_migrations change(**kw) File "./migrations/versions/318381ec60ba_indexes_4_deletes.py", line 22, in upgrade postgresql_ops = { 'resource_value', 'text_pattern_ops' } ) File "<string>", line 7, in create_index File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/operations.py", line 698, in create_index self._index(name, table_name, columns, schema=schema, **kw) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/ddl/impl.py", line 161, in create_index self._exec(schema.CreateIndex(index)) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/alembic/ddl/impl.py", line 76, in _exec conn.execute(construct, *multiparams, **params) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/engine/base.py", line 945, in execute return meth(self, multiparams, params) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/sql/ddl.py", line 68, in _execute_on_connection return connection._execute_ddl(self, multiparams, params) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/engine/base.py", line 996, in _execute_ddl if not self.schema_for_object.is_default else None) File "<string>", line 1, in <lambda> File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/sql/elements.py", line 436, in compile return self._compiler(dialect, bind=bind, **kw) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/sql/ddl.py", line 26, in _compiler return dialect.ddl_compiler(dialect, self, **kw) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/sql/compiler.py", line 216, in __init__ self.string = self.process(self.statement, **compile_kwargs) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/sql/compiler.py", line 242, in process return obj._compiler_dispatch(self, **kwargs) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/sql/visitors.py", line 81, in _compiler_dispatch return meth(self, **kw) File "/home/kgk/Envs/bq059/local/lib/python2.7/site-packages/sqlalchemy/dialects/postgresql/base.py", line 1670, in visit_create_index for expr in index.expressions TypeError: 'set' object has no attribute '__getitem__' An Unknown exception occured There was a problem initializing the Database -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
