特定模块在Django中有表单导入错误

Question

我在导入表单字段时遇到了一些问题。在我的 forms.py 文件里，有以下代码：

from django import forms
from django.forms import ModelForm
from koalified.seeker.models import *
from django.contrib.auth.models import User

class RegistrationForm(ModelForm):
    username = forms.CharField(label=(u'Username'))
    password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))
    ver_password = forms.CharField(label=(u' Verify Password'), widget=forms.PasswordInput(render_value=False))
    email = forms.EmailField()

    class Meta:
            model = Seeker
            exclude = ('user','verified','premium')

    def clean_username(self):
            ''' Checking username availability '''
            username = self.cleaned_data['username']
            try:
                    User.objects.get(username=username)
            except User.DoesNotExist:
                    if len(username)  >= 5 and len(username) < 21:
                        return self.cleaned_data['username']
                    else:
                        raise forms.ValidationError("Username must be between 5 and 20 characters")
            raise forms.ValidationError("That username is already in use")

    def clean_ver_password(self):
            password = self.cleaned_data.get('password')
            ver_password = self.cleaned_data.get('ver_password')

            if not ver_password:
                    raise forms.ValidationError("You must confirm your password")
            if password != ver_password:
                    raise forms.ValidationError("Passwords do not match")
            return ver_password

我一直收到“视图不存在”的错误。我查了一下，建议我去命令行（shell）尝试导入。以下是导入的输出结果：

Traceback (most recent call last):
    File "<console>", line 1, in <module>
    File "/home/jmcguffee1/django.koalified.com/koalified/koalified/seeker/forms.py", line 6, in <module>
    class RegistrationForm(ModelForm):
    File "/home/jmcguffee1/django.koalified.com/koalified/koalified/seeker/forms.py", line 7, in RegistrationForm
    username = forms.CharField(label=(u'Username'))
    AttributeError: 'module' object has no attribute 'CharField'

我查看了一些问题，发现有人可能是拼写错误，但我试了很多次，还是无法加载这个表单。我的其他模块，比如登录表单，工作得很好。

from django.contrib.auth.models import User
from django import forms

class LoginForm(forms.Form):
    username = forms.CharField(label=(u'Username'))
    password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))

我尝试手动导入字段，结果是可以的，比如：

from django.forms.fields import CharField, EmailField
username = CharField()

这样可以正常工作。我又回到命令行，导入了 django.forms，并尝试从那里加载。

from django import forms
username = forms.CharField(label=(u'用户名'))
username

我检查了 models.py 和 views.py，确认没有循环调用，也没有其他导入 django forms 的地方。看起来这个特定的模块没有正确加载表单字段。如果还有不清楚的地方，我可以提供更多信息。

这是问题的解决方案：

>>> from django import forms
>>> print 'form is : ', forms
form is :  <module 'django.forms' from '/home/jmcguffee1/django.koalified.com/kf/lib/python2.6/site-packages/Django-1.4.3-py2.6.egg/django/forms/__init__.pyc'>
>>> from koalified.seeker.models import *
>>> print 'form is : ', forms
form is :  <module 'django.forms.forms' from '/home/jmcguffee1/django.koalified.com/kf/lib/python2.6/site-packages/Django-1.4.3-py2.6.egg/django/forms/forms.pyc'>
