Question

I am facing some problems with model.py file

the code of model.py is:

from django.db import models

import datetime
from django.utils import timezone

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
 def __unicode__(self):
        return self.question
 def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)


class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice = models.CharField(max_length=200)
    votes = models.IntegerField()
 def __unicode__(self):
        return self.choice

when i am run this command python manage.py shell the following error occurs

File "/home/ghrix/testing/demo/polls/models.py", line 9
    def __unicode__(self):
                         ^
IndentationError: unindent does not match any outer indentation level

this error occur after i add some lines of code in my model.py file

import datetime from django.utils import timezone

In Poll class

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

In Choice class

def __unicode__(self):
        return self.choice

Answer 1

Python is very sensitive to indentation. Your particular code should look like this:

from django.db import models

import datetime
from django.utils import timezone

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

    def __unicode__(self):
        return self.question

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


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

    def __unicode__(self):
        return self.choice

Remember, the suggested indentation is 4 spaces for each level. The problem you’re having is that your attributes like say Poll.question should be defined at the same level as the method __unicode__.
