Question

我已经编写了以下代码，但我想不出如何引用EmploymentRecordForm中包含的 employment_record_date_display_type 的提交值。

我尝试了 employment_record_date_display_type = EmploymentRecordForm.employment_record_date_display_type ，但却出现以下错误：

类型对象'EmploymentRecordForm'没有属性'employment_record_date_display_type'

以下是我的forms.py文件中的验证码：

class EmploymentRecordForm(forms.ModelForm):
    .............
    def clean_employment_record_completion_date(self):

        employment_record_display_type = self.cleaned_data.get('employment_record_display_type')
        employment_record_date_display_type = ?????????
        employment_record_commencement_date = self.cleaned_data.get('employment_record_commencement_date')
        employment_record_completion_date = self.cleaned_data.get('employment_record_completion_date')

        if employment_record_display_type == 0:
            if employment_record_completion_date is not None and employment_record_commencement_date is not None:
                if employment_record_commencement_date > employment_record_completion_date:
                    if employment_record_date_display_type == 2 or employment_record_date_display_type == 3:
                        raise forms.ValidationError(_("To Date must be greater than the From Date."))
                    elif employment_record_date_display_type == 4 or employment_record_date_display_type == 5:
                        raise forms.ValidationError(_("Finish Date must be greater than the Start Date."))
                    elif employment_record_date_display_type == 6 or employment_record_date_display_type == 7:
                        raise forms.ValidationError(_("End Date must be greater than the Begin Date."))
                    elif employment_record_date_display_type == 8 or employment_record_date_display_type == 9:
                        raise forms.ValidationError(_("This Date must be greater than the other Date."))
                    else:
                        raise forms.ValidationError(_("Completion Date must be after the Commencement Date."))

        return employment_record_completion_date

如何引用jobs_record_date_display_type的提交值？

Answer 1

您应该编写自定义验证程序类，并在您希望应该具有验证程序列表属性的字段中。像这样：

price = models.IntegerField(validators=[MyCustomValidator])

django自定义验证 - 引用提交的表单值
