我正在从教程中学习djangorest框架，并坚持与授权和权限相关的第四个主题。
我收到了一个值错误，即
invalid literal for int() with base 10: 'owner_id'
我认为这与下面的models.py文件中Snippet模型中的所有者列有关
from django.db import models
from pygments.lexers import get_all_lexers, get_lexer_by_name
from pygments.styles import get_all_styles
from pygments import highlight
from pygments.formatters.html import HtmlFormatter
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())
# Create your models here.
class Snippet(models.Model):
created = models.DateTimeField(auto_now_add = True)
title = models.CharField(max_length = 100, blank = True, default = '')
code = models.TextField(default = '')
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)
owner = models.ForeignKey('auth.User', related_name = "snippets")
highlighted = models.TextField(default = "")
class Meta:
ordering = ('created',)
def save(self, *args, **kwargs):
"""
Use the `pygments` library to create a highlighted HTML
representation of the code snippet.
"""
lexer = get_lexer_by_name(self.language)
linenos = self.linenos and 'table' or False
options = self.title and {'title': self.title} or {}
formatter = HtmlFormatter(style=self.style, linenos=linenos,
full=True, **options)
self.highlighted = highlight(self.code, lexer, formatter)
super(Snippet, self).save(*args, **kwargs)
另外，找到views.py
from snippets.models import *

style = serializers.ChoiceField(choices=STYLE_CHOICES, default='friendly')
owner = serializers.ReadOnlyField(source='owner.username')
def create(self, validated_data):
return Snippet.objects.create(**validated_data)
def update(self, instance, validated_data):
instance.title = validated_data.get('title', instance.title)
instance.code = validated_data.get('code', instance.code)
instance.linenos = validated_data.get('linenos', instance.linenos)
instance.language = validated_data.get('language', instance.language)
instance.style = validated_data.get('codstylee', instance.style)
instance.save()
return instance
class UserSerializer(serializers.ModelSerializer):
snippets = serializers.PrimaryKeyRelatedField(many = True, queryset = Snippet.objects.all())
class Meta:
model = User
fields = {"id", "username", "snippets"}
和urls.py
from django.conf.urls import url
from snippets import views
from rest_framework.urlpatterns import format_suffix_patterns
urlpatterns = [
url(r'^snippets/$', views.SnippetList.as_view()),
url(r'^snippets/(?P<pk>[0-9]+)/$', views.SnippetDetail.as_view()),
url(r'^users/$', views.UserList.as_view()),
url(r'^users/(?P<pk>[0-9]+)/$', views.UserDetail.as_view()),
]
urlpatterns = format_suffix_patterns(urlpatterns)

python manage.py migrate
