Django Python __init __()TypeError'默认'教程

标签: python django default keyword typeerror

我正在浏览Django教程:https://docs.djangoproject.com/en/1.5/intro/tutorial01/

我有一个错误:

  

TypeError:__init__()有一个意外的关键字参数'Default'

当我打电话时会发生这种情况:

$python manage.py sql polls   

OR

$python manage.py syncdb

我被困住了,无法弄清楚我做错了什么。

我刚开始教程的“激活模型”部分并输入已安装的应用程序

引用: [settings.py]

'Engine': 'django.db.backends.sqlite3'
'NAME': '/Users/msmith/Documents/djangoPractice/database.db'

$ python manage.py syncdb

$ python manage.py startapp polls

[polls.models.py]

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(Default=0)

[settings.py] - 在列表底部添加了“民意调查”

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # Uncomment the next line to enable the admin:
    # 'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
    'polls',
)

$ python manage.py sql polls - >发生错误

在您的模型定义中,您有Default=而不是default=。检查案例。

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0) 
    #                           ^ Check the case here
