I am trying to run
python manage.py migrate
or
python manage.py makemigrations
I got this error:
Running migrations: No migrations to apply. Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line utility.execute() File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/core/management/__init__.py", line 345, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/core/management/base.py", line 348, in run_from_argv self.execute(*args, **cmd_options) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/core/management/base.py", line 399, in execute output = self.handle(*args, **options) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/core/management/commands/migrate.py", line 183, in handle executor.loader.project_state(), File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/db/migrations/loader.py", line 338, in project_state return self.graph.make_state(nodes=nodes, at_end=at_end, real_apps=list(self.unmigrated_apps)) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/db/migrations/graph.py", line 280, in make_state project_state = self.nodes[node].mutate_state(project_state, preserve=False) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/db/migrations/migration.py", line 88, in mutate_state operation.state_forwards(self.app_label, new_state) File "/Users/rostunov/temp/venv/lib/python2.7/site-packages/django/db/migrations/operations/models.py", line 547, in state_forwards model_state = state.models[app_label, self.name_lower] KeyError: ('list', u'user')
It happen after I pulled another version of my app from the git.
I don’t have this error with the same code on the another machine.
I’ve tried to use --fake
with zero
or to squashmigrations
to previous but this also doesn’t help.
Cannot get how to solve it.

Answer
The problem was in migration files.
While I was making commit into git somehow I’ve deleted one of the migration files, so the order was like 0001 0003 0004
without 0002
.
In the second migration file I’ve created a model named user.
The problem was that when I run python manage.py migrate
django could not find the place where the model named user has been created (this model has been created in 0002
file).
I solved it by manually adding this code to the 0001
migration file:
migrations.CreateModel( name='user', fields=[ (...necessary fields...), ], options={ 'ordering': ('title',), }, ),
