这段代码从DJANGO 哪里copy的  但是我mysql连接正常啊。。。

结果添加这段代码就报了错误。。

from django.db import models

class Publisher(models.Model):

    name = models.CharField(maxlength=30)

    address = models.CharField(maxlength=50)

    city = models.CharField(maxlength=60)

    salutation = models.CharField(maxlength=10)

    first_name = models.CharField(maxlength=30)

    last_name = models.CharField(maxlength=40)

    email = models.EmailField()

    headshot = models.ImageField(upload_to='/tmp')

class Book(models.Model):

    title = models.CharField(maxlength=100)

     authors = models.ManyToManyField(Author)

    publisher = models.ForeignKey(Publisher)

    publication_date = models.DateField()

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

是max_length而不是maxlength

maxlength or max_length ?

晕，楼上比我快。。

django 0.96之后对编码风格进行了修改，你用的是1.0之前的例子吧

对。。

嘿嘿，非常感谢大家~~  我这个问题在 官方的man找到了。。
