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)

这是我的settings.py INSTALLED APPS

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',
)

在此之后，我尝试使用以下命令验证SQL：

python manage.py sql directorio

我收到了这个错误：

Traceback (most recent call last):

    execute_manager(settings)

 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，有人能给我一些线索吗？

最诚挚的问候，

安德烈，

长度拼写为代码中的长度。请检查拼写错误。

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)
