Django-Haystack/Whoosh - Rebuild Index Error

Python 2.5, Django 1.2.1, most recent haystack, most recent whoosh

This is my first delve into Django-Haystack. I was following the "Getting Started" guide from Haystack and everything seemed to be going along fine, until I went to build the index.

So, running "manage.py rebuild_index" shot this back at me:

Traceback (most recent call last):
  File "/Users/steenb/Documents/Aptana Studio Workspace/bucksac/buckshr/manage.py", line 11, in <module>
    execute_manager(settings)

  File "/Library/Python/2.5/site-packages/haystack/backends/whoosh_backend.py", line 212, in clear
    self.index.commit()
AttributeError: 'FileIndex' object has no attribute 'commit'

Not sure even where to start with this... has anyone run into this before?

Any thoughts on a solution?

Update: Tried this with python 2.6 as well, got the same error. Is there some Whoosh configuration that I have not done?

Update: After using the below suggestion from philippbosch, the first error didn't show up anymore but now I am getting this:

    writer = AsyncWriter(self.index.writer, postlimit=self.post_limit)
TypeError: __init__() got an unexpected keyword argument 'postlimit'

I am wondering if I am using an incompatable version of Whoosh.... I grabbed the latest which is 1.0.0b2 ... http://pypi.python.org/pypi/Whoosh/

update: Turns out it is a version problem. Currently, Haystack is tied to whoosh 0.3.18

I had the same problem just now. Did you try »update_index« instead of »rebuild_index«? That seemed to work for me …

Installing Whoosh 0.3.18 solved the problem on my side

If you found this question while attempting to delete an entry from an index, you might need to use an IndexWriter to delete the entry, rather than a FileIndex object; e.g.:

Instead of:

ix = open_dir('index')
ix.delete_by_term('path', u'/a/b/c')
ix.commit()

which throws the error discussed above, you can delete a file by running:

ix = open_dir('index')
writer = ix.writer()
writer.delete_by_term('path', u'/a/b/c')
writer.commit()
