我正在使用django(1.5.11)和mongoDB(2.4.9)构建一个网站。由于我想添加REST API,我还安装了Django REST框架(3.0.5)。但我无法让序列化器与一个非常简单的模型一起正常工作(见下文),而是我得到了这个错误:
ValueError at /api/message/
invalid literal for int() with base 10
我认为这个错误与mongoDB标识符不是整数的事实有关。另请注意,我不想使用MongoEngine(和Django Rest Framework Mongoengine),因为我不想继续使用django哲学。
任何线索或提示?请在下面找到我的应用程序的最小示例。
models.py
from django.db import models
from djangotoolbox import fields
class Message(models.Model):
created_on = models.DateTimeField(auto_now_add=True, null=True)
text = models.TextField()
tags = fields.ListField()
views.py
from django import http, template
from rest_framework import generics, renderers, parsers
from . import models, serializers
def messageList(request):
if request.method == 'GET':
messages = models.Message.objects.all()
serializer = serializers.MessageSerializer(messages, many=True)
return JSONResponse(serializer.data)
class JSONResponse(http.HttpResponse):
def __init__(self, data, **kwargs):
content = renderers.JSONRenderer().render(data)
kwargs['content_type'] = 'application/json'
super(JSONResponse, self).__init__(content, **kwargs)
serializers.py
from rest_framework import serializers
from . import models
class MessageSerializer(serializers.ModelSerializer):
class Meta:
model = models.Message
fields=('id' , 'text',)
urls.py
from django.conf.urls import patterns, include, url
from . import views
urlpatterns = patterns('',
url(r'^api/message/$', views.messageList),
)
答案 0 :(得分:2)
您必须在序列化程序中将id字段添加为字段
<强> serializers.py 强>
class MessageSerializer(serializers.ModelSerializer):
id = serializers.CharField()
class Meta:
model = models.Message
fields=('id' , 'text',)
