Django Rest Framework serializer representation not working

I'm following the Django Rest Framework tutorial on serializers, but finding some unusual behavior. Where print repr(serializer_instance) is apparently supposed to print useful inspection, I can only get back this representation: 

<snippets.serializers.SnippetSerializer object at 0x10220f110>.

My code seems to line up exactly with that in the tutorial, and I'm using Django 1.7 and Python 2.7. Does anyone have any idea why this might be happening?

snippets/serializers.py:

from django.forms import widgets
from rest_framework import serializers
from snippets.models import Snippet, LANGUAGE_CHOICES, STYLE_CHOICES

class SnippetSerializer(serializers.ModelSerializer):

    class Meta:
        model = Snippet
        fields = ('id', 'title', 'code', 'linenos', 'language', 'style')

snippets/models.py:

from django.db import models
from pygments.lexers import get_all_lexers
from pygments.styles import get_all_styles

LEXERS = [item for item in get_all_lexers() if item[1]]
LANGUAGE_CHOICES = sorted([(item[1][0], item[0]) for item in LEXERS])
STYLE_CHOICES = sorted((item, item) for item in get_all_styles())

class Snippet(models.Model):
    created = models.DateTimeField(auto_now_add=True)
    title = models.CharField(max_length=100, blank=True, default='')
    code = models.TextField()
    linenos = models.BooleanField(default=False)
    language = models.CharField(choices=LANGUAGE_CHOICES, default='python', max_length=100)
    style = models.CharField(choices=STYLE_CHOICES, default='friendly', max_length=100)

    class Meta:
        ordering = ('created',)

shell:

$ python manage.py shell_plus
>>> from snippets.serializers import SnippetSerializer
>>> serializer = SnippetSerializer()
>>> serializer
    <snippets.serializers.SnippetSerializer object at 0x10220f110>
>>> print repr(serializer)
    <snippets.serializers.SnippetSerializer object at 0x10220f110>

I had the same problem until I realized that I had version 2.4 installed.

Simply read the release notes and update to version 3.0

E.g. if you use a requirements.txt, change the rest framework line to :

djangorestframework==3.0

and run 

pip install -r requirements.txt

I believe this is because you are returning the serializer object. In order to return the actual data you have to refer to the data attribute:

print repr(serializer.data)
