python - Django-Haystack/Whoosh - 重建索引错误

Question

Python 2.5，Django 1.2.1，最近的 haystack，最近的 whoosh

这是我第一次深入研究 Django-Haystack。我一直在遵循 Haystack 的“入门”指南，一切似乎都进行得很顺利，直到我开始构建索引。

所以，运行“manage.py rebuild_index”向我反击:

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/django/core/management/__init__.py", line 438, in execute_manager
    utility.execute()
  File "/Library/Python/2.5/site-packages/django/core/management/__init__.py", line 379, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 191, in run_from_argv
    self.execute(*args, **options.__dict__)
  File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 218, in execute
    output = self.handle(*args, **options)
  File "/Library/Python/2.5/site-packages/haystack/management/commands/rebuild_index.py", line 13, in handle
    call_command('clear_index', **options)
  File "/Library/Python/2.5/site-packages/django/core/management/__init__.py", line 166, in call_command
    return klass.execute(*args, **defaults)
  File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 218, in execute
    output = self.handle(*args, **options)
  File "/Library/Python/2.5/site-packages/haystack/management/commands/clear_index.py", line 38, in handle
    sb.clear()
  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'

甚至不知道从哪里开始......以前有人遇到过这个吗？

有什么解决方案吗？

更新:也用 python 2.6 试过这个，得到了同样的错误。是不是有什么Whoosh配置没做？

更新:使用 philippbosch 的以下建议后，第一个错误不再出现，但现在我得到了这个:

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/django/core/management/__init__.py", line 438, in execute_manager
    utility.execute()
  File "/Library/Python/2.5/site-packages/django/core/management/__init__.py", line 379, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 191, in run_from_argv
    self.execute(*args, **options.__dict__)
  File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 218, in execute
    output = self.handle(*args, **options)
  File "/Library/Python/2.5/site-packages/haystack/management/commands/update_index.py", line 69, in handle
    return super(Command, self).handle(*apps, **options)
  File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 282, in handle
    app_output = self.handle_app(app, **options)
  File "/Library/Python/2.5/site-packages/haystack/management/commands/update_index.py", line 123, in handle_app
    index.backend.update(index, small_cache_qs[start:end])
  File "/Library/Python/2.5/site-packages/haystack/backends/whoosh_backend.py", line 163, in update
    writer = AsyncWriter(self.index.writer, postlimit=self.post_limit)
TypeError: __init__() got an unexpected keyword argument 'postlimit'

我想知道我是否使用了不兼容的 Whoosh 版本....我捕获了最新的 1.0.0b2 ... http://pypi.python.org/pypi/Whoosh/

更新:原来是版本问题。目前，Haystack 绑定(bind)到 whoosh 0.3.18

我刚才遇到了同样的问题。您是否尝试使用 »update_index« 而不是 »rebuild_index«？这似乎对我有用……
