python - 没有搜索结果

Question

我刚刚使用 django 1.3 安装并设置了 haystack 和 solr，但是当我搜索(使用 haystack 默认模板)时，我什么也没得到。我复制并粘贴了 solr 架构并更新了索引，但没有得到任何结果。也许我的模型/表没有连接到 solr？我该如何解决？我不知道发生了什么......

非常感谢!

搜索索引:

class PostIndex(SearchIndex):
    text = CharField(document=True, use_template=False)

    def index_queryset(self):
        """Used when the entire index for model is updated."""
        return Post.objects.all()


site.register(Post, PostIndex)

搜索配置:

import haystack

haystack.autodiscover()

设置:

HAYSTACK_SITECONF = 'site.search_config'
HAYSTACK_SEARCH_ENGINE = 'solr'
HAYSTACK_SOLR_URL = 'http://127.0.0.1:8983/solr'

谢谢!

您需要以某种方式填充搜索索引中的text字段；将其映射到模型字段 - 或 - use a template for this !首先，您应该可以使用模板，因此设置 use_template=True 并添加模板。阅读 this paragraph有关如何创建模板文件的更多信息!
