Django-Haystack/Whoosh - 重建索引错误

Question

Python 2.5、Django 1.2.1、最近的干草堆、最近的嗖嗖

这是我第一次深入研究 Django-Haystack。我按照 Haystack 的“入门”指南进行操作，一切似乎都进行得很好，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？

对解决方案有什么想法吗？

更新： 也用 python 2.6 试过这个，得到了同样的错误。有没有我没有做过的 Whoosh 配置？

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：

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

    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....我抓住了最新的 1.0.0b2 ...http://pypi.python.org/pypi/Whoosh/

更新： 原来是版本问题。目前，Haystack 与 whoosh 0.3.18 相关联

Answer 1

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

Answer 2

安装Whoosh 0.3.18解决了我这边的问题

Answer 3

如果您在尝试从索引中删除条目时发现此问题，您可能需要使用IndexWriter 来删除该条目，而不是使用FileIndex 对象；例如：

代替：

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

抛出上面讨论的错误，您可以通过运行删除文件：

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