的Django模型：意外的关键字错误信息

我使用Django在几个星期前我开始一个Django应用程序，并写了model.py这些线路的Django模型：意外的关键字错误信息

from django.db import models 
class Publisher(models.Model): 
    name = models.CharField(max_length=30) 
    address = models.CharField(max_lenght=50) 
    city = models.CharField(max_length=60) 
    state_province = models.CharField(max_length=30) 
    country = models.model.CharField(max_length=50) 
    website = models.URLField() 

class Author(models.Model): 
    first_name = models.CharFiled(max_length=30) 
    last_name = models.CharField(max_length=40) 
    email = models.EmailField() 

class Book(models.Model): 
    title = models.CharField(max_length=100) 
    authors = models.ManyToManyField(Author) 
    publisher = models.ForeignKey(Publisher) 
    publication_date = models.DateField()

当我试图验证或sqlall

python manage.py validate 
or 
python manage.py sqlall appname

它打印此错误消息

    TypeError: __init__() got an unexpected keyword argument 'max_lenght'

请帮我解决这个错误

异常消息再清楚不过：

TypeError: __init__() got an unexpected keyword argument 'max_lenght'

这里的那一行，看起来像一个错字。

address = models.CharField(max_lenght=50) 
           ^

不想粗鲁，但是你有没有想读取错误信息？

unexpected keyword argument 'max_lenght'

（你拼错max_length）

编辑：

错误信息的绝对量可能会令人生畏，但有一个不错的提示，在第一行：

Traceback (most recent call last):

从底部开始寻找，你的错误可能被发现。

另一个提示（尽管这次没有帮助）是扫描你写的文件中的错误代码（而不是django库代码），有时在列表中间。
