我不知道为什么每当我添加一些验证码时，我网站索引页面上的这个表单都会产生属性错误。有谁能看到这个问题？
表格代码 -
region_choice = (
('', 'Region'),
('1', 'Auckland'),
('2', 'Wellington'),
('3', 'Christchurch')
)
suburb_choice = (
('', 'None'),
('1', 'Glendowie'),
('2', 'Kohimarama'),
('3', 'Herne Bay')
)
industry_choice = (
('', 'Business Industry'),
('1', 'Accounting'),
('2', 'Agriculture, fishing & forestry'),
('3', 'Automotive'),
('4', 'Banking, finance & insurance'),
('5', 'Construction & Architecture'),
('6', 'Customer service'),
)
employment_type_choice = (
('', 'None'),
('1', 'Full Time'),
('2', 'Part Time'),
('3', 'One-off'),
('4', 'Other')
)
class JobQuickSearchForm(forms.Form):
business_address_region = forms.ChoiceField(region_choice, required=False, widget=forms.Select(attrs={'class': 'qs-form-input'}))
business_industry = forms.ChoiceField(industry_choice, widget=forms.Select(attrs={'class': 'qs-form-input'}))
keywords = forms.CharField(max_length=20, widget=forms.TextInput(attrs={'class': 'qs-form-input', 'placeholder': 'Enter Keywords...'}))
def clean(self):
if self.business_address_region and self.business_industry and self.keywords == '':
raise ValidationError("You must specify either email or telephone")

我认为问题可能出在clean（）函数中。 尝试使用cleaning_data字典访问字段：
def clean(self):
cleaned_data = super(JobQuickSearchForm, self).clean()
if cleaned_data['business_address_region'] and cleaned_data['business_industry'] and cleaned_data['keywords'] == '':
raise ValidationError("You must specify either email or telephone")
我建议检查一下＆＃39;关键字＆＃39;在与空字符串进行比较之前键入cleaning_data。
if 'keywords' in cleaned_data ...
我没有测试它，但你可以尝试一下：）。
或者你可以跳过＆＃34; super＆＃34;调用，并使用self.cleaned_data，如文档中所示。

我相信您正在寻找清理过的数据，您应该能够像这样访问：
cleaned_data = super(JobQuickSearchForm, self).clean()
business_address_region = cleaned_data.get('business_address_region')
# etc.
