尝试从模型填充表单字段时出现NameError-Java 学习之路

我正在探索django表格并有一个问题，我希望有人可以帮助我 .

我正在效仿Creating forms from models | Django documentation

我有表格;

# forms.py

from django import forms
from my_project.my_app.models import Author

class AuthorForm(forms.Form):
    name = forms.CharField(max_length=100)
    title = forms.CharField(max_length=3,
            widget=forms.Select(choices=TITLE_CHOICES))
    birth_date = forms.DateField(required=False)

和模型;

#models.py

from django.db import models

TITLE_CHOICES = (
    ('MR', 'Mr.'),
    ('MRS', 'Mrs.'),
    ('MS', 'Ms.'),
)
class Author(models.Model):
    name = models.CharField(max_length=100)
    title = models.CharField(max_length=3, choices=TITLE_CHOICES)
    birth_date = models.DateField(blank=True, null=True)

    def __unicode__(self):
        return self.name

但是，当我尝试访问表单时收到以下错误;

名称为'TITLE_CHOICES'的NameError未定义请求方法：GET请求URL：http：//192.168.1.111：8000 / Django版本：1.2.4异常类型：NameError异常值：名称'TITLE_CHOICES'未定义

我是否应该做些什么来允许forms.py访问models.py中的TITLE_CHOICES？

提前致谢 .

TITLE_CHOICES 应该在类中定义：

from django.db import models

class Author(models.Model):
    TITLE_CHOICES = (
        ('MR', 'Mr.'),
        ('MRS', 'Mrs.'),
        ('MS', 'Ms.'),
    )
    name = models.CharField(max_length=100)
    title = models.CharField(max_length=3, choices=TITLE_CHOICES)
    birth_date = models.DateField(blank=True, null=True)

    def __unicode__(self):
        return self.name

并以形式：

from django import forms
from my_project.my_app.models import Author

class AuthorForm(forms.Form):
    name = forms.CharField(max_length=100)
    title = forms.CharField(max_length=3,
            widget=forms.Select(choices=Author.TITLE_CHOICES))
    birth_date = forms.DateField(required=False)
