Django Haystack-显示结果而无需搜索查询？ [英] Django Haystack - Show results without needing a search query?

问题描述

即使没有插入搜索查询，我仍要显示与选定方面匹配的所有结果。类似于某些商店应用程序的工作方式，例如亚马逊

I would like to display all results which match selected facets even though a search query has not been inserted. Similar to how some shop applications work e.g. Amazon

例如显示所有蓝色且价格在$ 10- $ 100之间的产品。

如果未指定搜索查询，Haystack不会返回任何值。

Haystack does not return any values if a search query is not specified.

有什么想法可以解决吗？

Any ideas how I can get around it?

谢谢！

推荐答案

如果有人还在寻找，则建议在干草堆代码中提供一个简单的解决方案：

If anyone is still looking, there's a simple solution suggested in haystack code:

https://github.com/toastdriven/django-haystack/blob/master /haystack/forms.py#L34

class SearchForm(forms.Form):
    def no_query_found(self):
    """
    Determines the behavior when no query was found.

    By default, no results are returned (``EmptySearchQuerySet``).

    Should you want to show all results, override this method in your
    own ``SearchForm`` subclass and do ``return self.searchqueryset.all()``.
    """
    return EmptySearchQuerySet()
