意外的缩进错误，但缩进看起来正确

问题描述

我一直在尝试运行此代码，并且抛出缩进错误.不管我尝试什么，结果都是一样的.

I have been trying to run this code and it throws an indent error. No matter what I try, the result is the same.

如果我删除def __str__(self):之前的缩进和其余代码，它可以正常工作，但是在输出时，它不显示问题，而是显示"Question object".

If I delete the indent before def __str__(self): and the rest of the code, it works fine, but on output, instead of displaying the question, it shows 'Question object'.

def __str__(self):
^
IndentationError: unexpected indent

这是代码:

from __future__ import unicode_literals
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.utils import timezone

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

    def __str__(self):
        return self.question_text

    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

    def __str__(self):
        return self.choice_text

推荐答案

我猜您正在混合使用空格和制表符....

I guess you are mixing spaces and tabs ....
