Django的教程惡作劇

Question

阿羅哈CHAPS，

經與Django的教程

https://docs.djangoproject.com/en/1.8/intro/tutorial01/

有一點小毛病正如你可以看到下面，它說「問題」沒有定義。

c:\Python34\Scripts\mysite>python manage.py makemigrations polls 
Traceback (most recent call last): 
File "manage.py", line 10, in <module>

class Choice(models.Model): 
File "c:\Python34\Scripts\mysite\polls\models.py", line 8, in Choice 
question = models.ForeignKey(Question) 
NameError: name 'Question' is not defined 

這裏是我的models.py文件提前

from django.db import models 

class Question(models.Model): 
question_text = models.CharField(max_length=200) 
pub_date = models.DateTimeField('date published') 

class Choice(models.Model): 
    question = models.ForeignKey(Question) 
    choice_text = models.Charfield(max_length=200) 
    votes = models.IntegerField(default=0) 

感謝所有幫助

Answer 1

不嵌套類。讓你的縮進級別正確。選擇需要與問題處於同一水平，而不是問題內部。這裏的錯誤縮進和堆棧跟蹤會將其刪除。

Answer 2

from django.db import models 

class Question(models.Model): 
    question_text = models.CharField(max_length=200) 
    pub_date = models.DateTimeField('date published') 

class Choice(models.Model): 
    question = models.ForeignKey(Question) 
    choice_text = models.Charfield(max_length=200) 
    votes = models.IntegerField(default=0) 

Identation是問題
