Django 2.0 haystack whoosh update index, rebuild index throw error

Question

I am using django 2.0 with haystack+whoosh as a search. I configured as it is said in the documentation. Occurred problem is when i run ./manage.py rebuild_index it shows this error:

Traceback (most recent call last):
  File "./manage.py", line 15, in <module>
    execute_from_command_line(sys.argv)
  File "/home/zorig/.virtualenvs/ftm/lib/python3.5/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line

TypeError: Unknown option(s) for clear_index command: batchsize, workers. Valid options are: commit, help, interactive, no_color, nocommit, noinput, pythonpath, settings, skip_checks, stderr, stdout, traceback, using, verbosity, version.

after that i tried update_index it shows me this error:

values.append(current_object())
TypeError: __call__() missing 1 required keyword-only argument: 'manager'

So has anyone faced this error? Is it related to django 2.0 because i managed it work well with django 1.11.

Answer 1

Your installed version of Haystack does not support Django 2.0. Support for Django 2.0 was added in Haystack 2.8, which was released in March 2018.
