无效的Django表单

Question

我有一个未通过is_valid()测试的表格.我创建了一个相同的表单,通过相同的数据输入传递测试.不知道为什么一个人会通过,一个人会失败.

以下是表格:

choices = ( (1,'Yes'),(0,'No'),
      )

class ActivitySaveForm(forms.Form):
    name = forms.CharField(
        label=u'Activity Name',
        widget=forms.TextInput(attrs={'size': 64})
    )
    url = forms.URLField(
        label=u'URL',
        widget=forms.TextInput(attrs={'size': 64})
    )
    desc = forms.CharField(
        label=u'Describe it',
                widget=forms.TextInput(attrs={'size': 250})
    )
    created = forms.DateField(
        label=u'Date Entered',initial=datetime.date.today,
    )
    priority = forms.CharField(
        label=u'priority: 1-5',
            widget=forms.TextInput(attrs={'size': 1})
    )
    difficulty = forms.CharField(
        label=u'How hard is it? 1-5',
            widget=forms.TextInput(attrs={'size': 1})
    )
    done = forms.TypedChoiceField(choices=choices, widget=forms.RadioSelect, coerce=int
    )   
    tags = forms.CharField(
        label=u'Tags',required=False,
            widget=forms.TextInput(attrs={'size': 64})
    )
#def __init__(self, *args, **kwargs):
    #super(CircuitForm, self).__init__(*args, **kwargs)

    #for key in self.fields:
        #self.fields[key].required = False


class AcTest(forms.Form):
    name = forms.CharField(
        label=u'Activity Name',
        widget=forms.TextInput(attrs={'size': 64})
    )
    url = forms.URLField(
        label=u'URL',
        widget=forms.TextInput(attrs={'size': 64})
    )
    desc = forms.CharField(
        label=u'Describe it',
                widget=forms.TextInput(attrs={'size': 250})
    )
    created = forms.DateField(
        label=u'Date Entered',initial=datetime.date.today,
    )
    priority = forms.CharField(
        label=u'priority: 1-5',
            widget=forms.TextInput(attrs={'size': 1})
    )
    difficulty = forms.CharField(
        label=u'How hard is it? 1-5',
            widget=forms.TextInput(attrs={'size': 1})
    )
    done = forms.TypedChoiceField(choices=choices, widget=forms.RadioSelect, coerce=int
    )   
    tags = forms.CharField(
        label=u'Tags',required=False,
            widget=forms.TextInput(attrs={'size': 64})
    )

以下是两者的测试和结果.

>>> data = {'name':'test',
...         'url': 'www.test.com',
...         'desc':'test desc',
...         'created': '01/01/1900',
...         'priority':1,
...         'difficulty':1,
...         'desc':'test desc',
...         'tags':'test desc'}
>>> f=ActivitySaveForm(data)
>>> f.is_valid()
False
>>> f=AcTest(data)
>>> f.is_valid()
True

不知道如何进一步诊断此错误,并没有找到使其工作的方法.感谢您的帮助.

我运行你的代码,对我来说,两种形式都无法验证.您可以这样做:print f.errors您将获得验证期间创建的错误消息的HTML.

为此,我得到:

<ul class="errorlist"><li>done<ul class="errorlist"><li>This field is required.</li></ul></li></ul>

换句话说,即使需要,您也没有为'done'字段指定值.添加'done':1到data字典后,表单将验证.

至于为什么一个表单被验证而另一个表单没有...我将所有这些都粘贴到一个小程序中,你可能会发现它们的行为方式相同.我只能推测出于某些原因你在两种情况下都没有真正传递相同的数据.或者当你进行测试时,表格中存在细微差别.但我不能确定.

无论如何,尝试打印错误,你应该获得洞察力.
