Description
Hi,
makemigrations very often fails under python3 with the following traceback:
$ python manage.py makemigrations Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line utility.execute() File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/core/management/__init__.py", line 377, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/core/management/base.py", line 288, in run_from_argv self.execute(*args, **options.__dict__) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/core/management/base.py", line 338, in execute output = self.handle(*args, **options) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/core/management/commands/makemigrations.py", line 111, in handle convert_apps=app_labels or None, File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/migrations/autodetector.py", line 40, in changes changes = self._detect_changes(convert_apps, graph) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/migrations/autodetector.py", line 107, in _detect_changes self.old_apps = self.from_state.render(ignore_swappable=True) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/migrations/state.py", line 67, in render model.render(self.apps) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/migrations/state.py", line 311, in render body, File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/models/base.py", line 171, in __new__ new_class.add_to_class(obj_name, obj) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/models/base.py", line 300, in add_to_class value.contribute_to_class(cls, name) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/models/fields/related.py", line 1572, in contribute_to_class super(ForeignObject, self).contribute_to_class(cls, name, virtual_only=virtual_only) File "/home/stefan/.virtualenvs/python3/lib/python3.4/site-packages/django/db/models/fields/related.py", line 264, in contribute_to_class 'app_label': cls._meta.app_label.lower() TypeError: unsupported operand type(s) for %: 'bytes' and 'dict'
Using python2 instead fixes the problem. I use Django 1.7 from pip.
