python - django教程: unexpected indent error

Question

这是我的 model.py 代码:

from django.db import models
# Create your models here.

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
        def __str__(self):
        return self.question


class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)
        def __str__(self):
        return self.choice_text

当我运行以下命令时:

python manage.py runserver

这给了我以下错误:

mjrulesamrat@mjrulesamrat-Lenovo-G570:~/django_local/first_web$ python manage.py runserver Validating models...

Unhandled exception in thread started by Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/django/utils/autoreload.py", line 93, in wrapper fn(*args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/django/core/management/commands/runserver.py", line 98, in inner_run self.validate(display_num_errors=True) File "/usr/local/lib/python2.7/dist-packages/django/core/management/base.py", line 310, in validate num_errors = get_validation_errors(s, app) File "/usr/local/lib/python2.7/dist-packages/django/core/management/validation.py", line 34, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/usr/local/lib/python2.7/dist-packages/django/db/models/loading.py", line 196, in get_app_errors self._populate() File "/usr/local/lib/python2.7/dist-packages/django/db/models/loading.py", line 75, in _populate self.load_app(app_name, True) File "/usr/local/lib/python2.7/dist-packages/django/db/models/loading.py", line 99, in load_app models = import_module('%s.models' % app_name) File "/usr/local/lib/python2.7/dist-packages/django/utils/importlib.py", line 40, in import_module import(name) File "/home/mjrulesamrat/django_local/first_web/polls/models.py", line 7 def str(self): ^ IndentationError: unexpected indent

我正在使用 Django 1.6 和 python 2.7。

如果我在此代码中犯了一些错误，请指导我。因为当我在 python shell 中运行 follow 时，它给了我 poll 对象而不是问题。

>>> Poll.objects.all()
[<Poll: Poll object>]

观察/修复模型方法级别的缩进:

from django.db import models
# Create your models here.

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

    # HERE 
    def __str__(self):
        return self.question


class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

    # AND HERE
    def __str__(self):
        return self.choice_text
