我的一些远程Celery任务似乎永远不会成为我的经纪人(RabbitMQ).这appears是随机发生的.我的日志中没有错误,它们永远不会发送给工作人员或失败.Flower/Rabbit从不报告任务失败.

我曾经tcpflow -p -c -i eth0 port 5672监控发送任务的API上的流量(client).

当API成功发送任务时,传出流量的记录如下:

当我尝试在运行10.8的MAC上的virtualenv中安装MySQL-python时出现以下错误.

vertualenv EnvironmentError: mysql_config not found

如何确定安装的ColdFusion服务器是32位还是64位？

我很乐意看到一个解决我的问题的答案,无论是登录服务器还是以编程方式从CFML代码.

我已经设置了一个新的Amazon Linux实例,下一步安装Railo的步骤是什么？

尝试运行Django开发服务器时出现以下错误.我正在使用OS X 10.8.我还使用virtualenv系统安装包.

在我的Django设置中,我有以下内容:

DEBUG = os.environ ['DEBUG_VALUE']

哪里 DEBUG_VALUE = False

但是,当我这样做时,Django继续显示完整的错误消息.如果我手动添加DEBUG = False它工作,并显示500错误.

出于某种原因,Django在使用该os.environ值时忽略了它.

我确认DEBUG_VALUE是False但输出到文件.

我甚至尝试过:

DEBUG = bool(os.environ ['DEBUG_VALUE'])

并仍显示完整错误.

Django Rest Framework 有一个PrimaryKeyRelatedField，它列出了我与类别的关系的 ID many-to-many...

class CatalogueItemsSerializer(serializers.HyperlinkedModelSerializer):
    url = serializers.HyperlinkedIdentityField(view_name='catalogue_item_detail')
    name = serializers.CharField(min_length=2, max_length=60)
    categories = serializers.PrimaryKeyRelatedField(many=True, read_only=True)

我想覆盖create()类别字段上获取大量发布的 ID（传统上 DRF 希望我发送 URL）。

JSON 帖子：

{
"name": "test",
"categories": [1,2]
}

序列化器创建：

def create(self, validated_data):
    categories = validated_data.pop('categories', None)
    print(categories) # This shows and empty/None even when ID are posted!

我遇到的问题是categories上面是空的，我假设因为PrimaryKeyRelatedField设置为read_only=True，但根据 DRF，这必须为真。

我的问题是...如何使用PrimaryKeyRelatedFieldwithvalidated_data.pop来获取我提交的 ID 列表？

我可以使用self.context.get("request").data['categories']，但这很糟糕，需要我把它变成一个列表+其他东西。

我最近为我的 django 项目之一编写了一些测试。我现在想做的是从脚本调用测试命令。

我希望解析测试结果并保存它们。这对于 django 测试框架来说是可能的吗？

在执行任何迁移命令时,我正在努力在Django中调试模糊的错误消息:

我正在尝试更新DRF transform_<name>以使用新to_representation方法。当我尝试执行此操作时，出现以下错误，我很难找到。我已经在所有序列化器上对此进行了测试，并且得到了相同的结果：
