Django ModelForm没有调用干净

Question

我正在执行基本的Django ModelForm创建/验证/保存操作.当在Eclipse调试器下运行代码时调用is_valid()并且在创建表单和调用is_valid()之后设置断点时,不会调用我的自定义清理方法.

我已经多次遍历Django基本代码,看起来ModelForm类上的错误字典从未设置为None,这会触发验证.我怀疑这是由于与调试器的交互访问ModelForm的_errors属性以显示在变量窗格中.

当我删除所有断点并让代码自然流动时,我可以通过发出print语句来证明自定义清理代码正在运行.

这是Django ModelForm设计中的一个缺陷,Eclipse问题还是我咆哮错误的树？

models.py

from django.db import models

class TestModel1(models.Model):
    field1 = models.CharField(max_length=45)
    field2 = models.IntegerField(default=2)
    field3 = models.CharField(max_length=45, null=True, blank=True)

forms.py

from order.models import TestModel1
from django.forms import ModelForm

class OrderTestForm(ModelForm):

    def clean_field1(self):
        return self.cleaned_data['field1']

    def clean_field2(self):
        return self.cleaned_data['field2']

    class Meta:
        model = TestModel1

我的测试工具:

from forms import OrderTestForm

row = {'field1': 'test value', 'field2': '4', }

ff = OrderTestForm(row)

#ff.full_clean()
if ff.is_valid():
    ff.save()
else:
    print ff.errors

如果你尝试：

from order.models import TestModel1
from django.forms import ModelForm

class OrderTestForm(ModelForm):
    class Meta:
        model = TestModel1

    def clean_field1(self):
        value = self.cleaned_data['field1']
        print value 
        return value

    def clean_field2(self):
        value = self.cleaned_data['field2']
        print value 
        return value
