Django中的新应用程序问题

Question

我是Django的新手。我创建了一个名为“Directorio”的新应用程序，现在我需要验证SQL。

这里是我的models.py

from django.db import models 

class Directorio(models.Model): 
    n_site = models.CharField(max_length=60) 
    url = models.CharField(max_length=100) 
    user_db_ins = models.CharField(max_lenght=50) 
    user_db_upd = models.CharField(max_lenght=50) 
    user_system_ins = models.CharField(max_lenght=50) 
    user_system_upd = models.CharField(max_lenght=50) 
    date_inserted = models.DateTimeField(auto_now_add=True) 
    date_last_update = models.DateTimeField(auto_now=True) 

这里是我的settings.py安装的应用程序

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

这个我想validade用命令的SQL后：

python manage.py sql directorio 

而我得到这个错误：

Traceback (most recent call last): 
    File "manage.py", line 11, in <module> 
    execute_manager(settings)

    models = import_module('.models', app_name)

545, in __init__ 
    super(CharField, self).__init__(*args, **kwargs) 
TypeError: __init__() got an unexpected keyword argument 'max_lenght' 

我无法理解错误，有人能给我一个线索吗？

最好的问候，

安德烈，

长度拼写为你的代码lenght。请检查错误。

user_db_ins = models.CharField(max_lenght=50) 
user_db_upd = models.CharField(max_lenght=50) 
user_system_ins = models.CharField(max_lenght=50) 
user_system_upd = models.CharField(max_lenght=50)
