Question

所以我尝试使用自定义搜索表单，以便我可以分别搜索多个模型字段。（比如，按资产＃，按部门等搜索设备）我现在有以下代码：

SEARCH_CHOCIES = (('Asset #','Asset #'), ('Calibrated by','Calibrated by'), ('Department','Department'),
 ('Description','Description'), ('Expiring soon','Expiring soon'), ('Flagged','Flagged'),
     ('Manufacturer','Manufacturer'), ('Model','Model'), ('Serial #','Serial #'), ('Test','Test'))

class MultipleSearchForm(SearchForm):
    search_type = forms.ChoiceField(required = False, choices = SEARCH_CHOCIES)
    search_content = forms.CharField(required = False)

    def search(self):
        sqs = super(MultipleSearchForm, self).search()

        if not self.is_valid():
            return self.no_query_found()
        choice = self.cleaned_data['search_type']
        content = self.cleaned_data['search_content']
        if choice:
            if content:
                if choice == 'Asset #':
                    sqs = sqs.filter(self.cleaned_data['asset_number'] == content)

        return sqs

urls.py：

url(r'^search/', search_view_factory(view_class = SearchView, form_class = MultipleSearchForm), name='haystack_search'),

现在它只在您选择按资产＃搜索时处理搜索。我有以下问题：

当我尝试使用此功能时，转到http://127.0.0.1:8000/calbase/search/并按资产＃搜索，我收到以下错误消息：

/ calbase / search /
中的KeyError
＆＃39; asset_number＆＃39;

Exception Type: KeyError at /calbase/search/
Exception Value: 'asset_number'

这里我只想比较＆＃34; asset_number＆＃34;查询结果字段与搜索内容一起查找我们想要搜索的内容。这里有什么问题？

现在在搜索视图中，除了我创建的搜索类型和搜索内容之外，还有旧的＆＃34;搜索＆＃34;领域。我怎么杀了它？
对于某些搜索类型，例如部门和测试，我希望搜索内容字段也是一个选择字段，以便用户可以从下拉菜单中进行选择。对于所有其他搜索类型，我希望搜索内容只是一个字段。这可行吗？

非常感谢
