Question

我想自定义搜索表单的SearchQuerySet以搜索所有可能的结果，例如sql表达式＆＃34; LIKE＆＃34;，文档说：

SearchForm   最基本的表单类型，此表单由单个字段q字段（用于查询）组成。在搜索时，表单将获取q字段的已清理内容，并在您提供的自定义SearchQuerySet或默认SearchQuerySet上执行auto_query。

要自定义表单将使用的SearchQuerySet，请使用您要使用的SearchQuerySet将searchqueryset参数传递给构造函数。如果将此表单与SearchView结合使用，表单将接收您为视图提供的任何SearchQuerySet，而无需额外的工作。

可以将auto_query更改为icontains搜索吗？

这是我的班级，我必须修改？：

class ContactSearchForm(HighlightedModelSearchForm):
    name = forms.CharField(max_length=100,required=False)
    surname = forms.CharField(max_length=100,required=False)
    work = forms.CharField(max_length=100,required=False)
    province =  forms.CharField(max_length=100,required=False)
    status = forms.CharField(max_length=100,required=False)
    sex =  forms.CharField(max_length=100,required=False)
    city =  forms.CharField(max_length=100,required=False)
    street =  forms.CharField(max_length=100,required=False)
    zip =  forms.CharField(max_length=100,required=False)


    def no_query_found(self):
        return self.searchqueryset

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

        if not self.is_valid():
            return self.no_query_found()

        if self.cleaned_data['name']:
            sqs = sqs.filter(content__icontains = self.cleaned_data["name"])
        if self.cleaned_data['surname']:
            sqs = sqs.filter(content__icontains = self.cleaned_data['surname'])
        if self.cleaned_data['work']:
            sqs = sqs.filter(content__icontains = self.cleaned_data['work'])
        if self.cleaned_data['province']:
             sqs = sqs.filter(content__icontains = self.cleaned_data['province'])
        if self.cleaned_data['status']:
             sqs = sqs.filter(content__icontains = self.cleaned_data['status'])
        if self.cleaned_data['sex']:
             sqs = sqs.filter(content__icontains = self.cleaned_data['sex'])
        if self.cleaned_data['city']:
            sqs = sqs.filter(content__icontains = self.cleaned_data['city'])
        if self.cleaned_data['street']:
            sqs = sqs.filter(content__icontains = self.cleaned_data['street'])
        if self.cleaned_data['zip']:
            sqs = sqs.filter(content__icontains = self.cleaned_data['zip'])

        return sqs

问题是你正在调用已经执行auto_query的父类搜索方法。你不需要这样做：

sqs = super(ContactSearchForm,self).search()

相反，这应该是您的搜索方法：

def search(self):
    if not self.is_valid():
        return self.no_query_found()

    sqs = self.searchqueryset
    for key, value in self.cleaned_data.items():
        if value:
            sqs = sqs.filter(content__icontains=value)

    if self.load_all:
        sqs = sqs.load_all()

    return sqs
