I am using a basic scenario in which I run upgrade on an empty db using
Flask-Migrate and alembic. This used to work under Alembic 0.6.7, but now
I'm getting this:
File "/usr/local/lib/python2.7/site-packages/flask_migrate/__init__.py",
line 98, in upgrade
command.upgrade(config, revision, sql = sql, tag = tag)
File "/usr/local/lib/python2.7/site-packages/alembic/command.py", line
165, in upgrade
script.run_env()
File "/usr/local/lib/python2.7/site-packages/alembic/script.py", line
382, in run_env
util.load_python_file(self.dir, 'env.py')
File "/usr/local/lib/python2.7/site-packages/alembic/util.py", line 241,
in load_python_file
module = load_module_py(module_id, path)
File "/usr/local/lib/python2.7/site-packages/alembic/compat.py", line 79,
in load_module_py
mod = imp.load_source(module_id, path, fp)
File "migrations/env.py", line 72, in <module>
run_migrations_online()
File "migrations/env.py", line 65, in run_migrations_online
context.run_migrations()
File "<string>", line 7, in run_migrations
File "/usr/local/lib/python2.7/site-packages/alembic/environment.py",
line 742, in run_migrations
self.get_context().run_migrations(**kw)
File "/usr/local/lib/python2.7/site-packages/alembic/migration.py", line
296, in run_migrations
for step in self._migrations_fn(heads, self):
File "/usr/local/lib/python2.7/site-packages/alembic/command.py", line
154, in upgrade
return script._upgrade_revs(revision, rev)
File "/usr/local/lib/python2.7/site-packages/alembic/script.py", line
303, in _upgrade_revs
revs = list(revs)
File "/usr/local/lib/python2.7/site-packages/alembic/revision.py", line
581, in _iterate_revisions
upper_ancestors = set(self._get_ancestor_nodes(uppers, check=True))
File "/usr/local/lib/python2.7/site-packages/alembic/revision.py", line
551, in _iterate_related_revisions
map_[rev_id] for rev_id in fn(rev))
File "/usr/local/lib/python2.7/site-packages/alembic/revision.py", line
531, in <lambda>
fn = lambda rev: rev._all_down_revisions
AttributeError: 'NoneType' object has no attribute '_all_down_revisions'
I'm not sure this is an Alembic issue, but not sure where to start
investigating either... Any clues anyone?
Thanks
