Question

我收到了这个错误：

IndentationError：使用unicode时预期会出现缩进块

但没有：

def __unicode__(self):
    return self.BankName

它正常工作。

我的models.py:

from django.db import models
class Bank(models.Model):
    BankName=models.CharField(max_length=20)
    CardNum=models.CharField(max_length=20)
    def __unicode__(self):
    return self.BankName

输入python manage.py runserver

时

Validating models...

    return  self.BankName
         ^
IndentationError: expected an indented block

请帮帮我。

from django.db import models
class Bank(models.Model):
    BankName=models.CharField(max_length=20)
    CardNum=models.CharField(max_length=20)
    def __unicode__(self):
        return self.BankName

请read the Python tutorial sections on control structures, which describes multi-level indentation。
