Question

这是我的forms.py

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

class RegistrationForm(forms.Manipulator):
    def __init__(self):
        self.fields = (
            forms.TextField(field_name='username',
                            length=30, maxlength=30,
                            is_required=True, validator_list=[validators.isAlphaNumeric,
                                                              self.isValidUsername]),
            forms.EmailField(field_name='email',
                             length=30,

    def save(self, new_data):
        u = User.objects.create_user(new_data['username'],

        u.is_active = False
        u.save()

这是我打算使用的模板 https://github.com/yourcelf/django-registration-defaults/tree/master/registration_defaults/templates。

根据它，我在settings.py中做了更改，但它给了我一个错误

Error: Can't find the file 'settings.py' in the directory containing 'manage.py'. It appears you've customized things.
You'll have to run django-admin.py, passing it your settings module.
(If the file settings.py does indeed exist, it's causing an ImportError somehow.)

使用这些模板是个好主意还是应该使用我自己的自定义模板？

Answer 1

哇，您使用的是什么版本的Django？ forms.Manipulator在1.0版本中被删除 - 三年前 - 在此之前被弃用了一年。

Answer 2

我猜你的项目有一个导入问题 - 但是Django抓住了这个并没有向你展示真正的错误。请注意，这不需要从settings.py导入 - 它可以在项目的任何位置导入。

尝试跑步：

python settings.py

python应该告诉你导入问题是什么。如果没有输出，你的问题就在其他地方 - 但这很可能是候选人。

在django中创建注册模板时出错。怎么调试？
