python - 使用mysql syncdb错误

Question

(我在 django 1.6 上使用 python2.7.6)

我已经使用 django 创建了一个应用程序调用注册，当我使用 sqlite 时我可以毫无问题地执行 python manage.py syncdb 但现在我使用 mysql 我收到此消息:

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

    models = import_module('%s.models' % app_name)

    class SignUp(models.Model):
  File "/var/www/firstweb/signups/models.py", line 7, in SignUp
    first_name = models.CharField(max_lenght=255, null=True, blank=True)
  File "/usr/local/lib/python2.7/dist-packages/django/db/models/fields/__init__.py", line 685, in __init__
    super(CharField, self).__init__(*args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'max_lenght'

这是我在 models.py 中的应用:

from django.db import models
from django.utils.encoding import smart_unicode

# Create your models here.

class SignUp(models.Model):
        first_name = models.CharField(max_lenght=255, null=True, blank=True)
        last_name = models.CharField(max_lenght=255, null=True, blank=True)
        email = models.EmailField()
        timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
        updated = models.DateTimeField(auto_now_add=False, auto_now=True)

        def __unicode__(self):
                return smart_unicode(self.email)

您只是打错了字:使用“max_length”而不是“max_lenght”:

class SignUp(models.Model):
    first_name = models.CharField(max_length=255, null=True, blank=True)
    last_name = models.CharField(max_length=255, null=True, blank=True)
    email = models.EmailField()
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True)

    def __unicode__(self):
            return smart_unicode(self.email)
