我正在尝试将 Haystack 和 Whoosh 与我的 Django 应用程序结合使用。我按照 Haystack 文档上的步骤操作，但在搜索时出现此错误

AttributeError at /search/
'module' object has no attribute 'get_model'

search_indexes.py -

import datetime
from haystack import indexes
from movies.models import Movie


class MovieIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    title = indexes.CharField(model_attr='title')

    def get_model(self):
        return Movie

    def index_queryset(self, using=None):
        """Used when the entire index for model is updated."""
        return self.get_model().objects.all()

我在任何地方都找不到关于这个错误的帮助，我做错了什么？

最佳答案

在我看来，这像是 Haystack 和 Django 版本之间的兼容性问题。 Django 最近重新设计了 get_model 系统(我认为在 1.9 中)，所以如果您升级了 Django 而不是 Haystack - 或者反之亦然 - 这可能就是问题所在。

我猜索引文件中的 get_model() 引用是一个潜在的转移注意力的问题，问题出在 Haystack 内部，因为它无法在它所在的位置找到该方法预计。

关于python - Django-Haystack 给出属性错误？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34576561/
