python之在 django rest framework searchfilter 中禁用多重搜索

有没有办法使用 SearchFilter 在 Django-rest-framework 中禁用多重搜索？

默认情况下，如果空格和/或逗号出现在搜索字符串中，django-rf 将应用多重搜索。

xyz.com/?search=x,y

此搜索将返回包含 x 或 y(以逗号分隔)的结果。

我想让它返回的结果包含“x,y”作为字符串的一部分。

请您参考如下方法:

很难为此想出一个好的论据和用例，但既然你想实现这样的搜索，你就必须需要它。 我会将现有的 SearchFilter 子类化并覆盖 filter_queryset 方法:

 def filter_queryset(self, request, queryset, view): 
    search_fields = getattr(view, 'search_fields', None) 
    search_terms = self.get_search_terms(request) 
 
    if not search_fields or not search_terms: 
        return queryset 
 
    orm_lookups = [ 
        self.construct_search(six.text_type(search_field)) 
        for search_field in search_fields 
    ] 
 
    base = queryset 
    conditions = [] 
    for search_term in search_terms: 
        queries = [ 
            models.Q(**{orm_lookup: search_term}) 
            for orm_lookup in orm_lookups 
        ] 
        conditions.append(reduce(operator.or_, queries)) 
    queryset = queryset.filter(reduce(operator.and_, conditions)) 
 
    if self.must_call_distinct(queryset, search_fields): 
        # Filtering against a many-to-many field requires us to 
        # call queryset.distinct() in order to avoid duplicate items 
        # in the resulting queryset. 
        # We try to avoid this if possible, for performance reasons. 
        queryset = distinct(queryset, base) 
    return queryset 

这是该方法的外观。看一眼它会告诉你这一行: conditions.append(reduce(operator.or_, queries)).

您可以将其更改为: conditions.append(reduce(operator.and_, queries)).

这可能会返回您预期的结果
