    field1 = forms.CharField(max_length=100)
    field2 = forms.EmailField()

    def clean_field1(self):
        data = self.cleaned_data['field1']
        # 添加特定的验证逻辑
        if len(data) < 5:
            raise forms.ValidationError("字段1的长度不能少于5个字符")
        return data

from django.shortcuts import render

            pass
    else:
        form = MyForm()
    
    return render(request, 'my_template.html', {'form': form})
