我有一个django网站,它使用Haystack和Xapian后端进行搜索索引。我为其中一个正在索引的模型添加了一个新字段,然后将该字段添加到该模型的SearchIndex中。我已经运行:django-haystack - 将新字段添加到索引后更新索引导致错误
python manage.py update_index
更新索引,但我发现了以下错误:

我使用的版本是1.2的Django Django的和,草垛1.0。 1。将这些升级到最新版本目前不适合我。
我解决了这个问题,在search_indexes中为空字段添加了'null = True'。 – Paolo
@Guandalino:我认为我的问题一定与你的问题有所不同,正如你从下面的答案中看到的解决方案是相反的 – hellsgate
