Question

（我在django 1.6上使用python2.7.6）

我用django创建了一个应用程序调用注册，当我使用sqlite我没有问题做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)

  File "/usr/local/lib/python2.7/dist-packages/django/db/models/loading.py", line 99, in load_app
    models = import_module('%s.models' % app_name)
  File "/usr/local/lib/python2.7/dist-packages/django/utils/importlib.py", line 40, in import_module
    __import__(name)
  File "/var/www/firstweb/signups/models.py", line 6, in <module>
    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)

你有一个错字：使用＆＃39; max_length＆＃39;而不是＆＃39; max_lenght＆＃39;：

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)

使用mysql的syncdb错误
