干草堆改变SearchQuerySet of SearchForm

Question

我希望自定义搜索表单的SearchQuerySet，以搜索所有可能的结果，比如sql表达式" like "，文档中这样写道：

SearchForm最基本的表单类型，这个表单包含一个字段，Q字段(用于查询)。在搜索时，表单将获取Q字段的清理内容，并在您提供的自定义SearchQuerySet或关闭默认SearchQuerySet上执行一个SearchQuerySet。 要自定义表单将使用的SearchQuerySet，请将一个searchqueryset参数传递给构造函数，其中包含您想要使用的SearchQuerySet。如果将此表单与SearchView结合使用，该表单将收到您向视图提供的任何SearchQuerySet，而不需要额外的工作。

是否可以将auto_query更改为图标搜索？

那是我的课，我要修改的地方是：

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

Answer 1

问题是您正在调用已执行auto_query的父类搜索方法。你不需要这么做

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
