小编Dmi*_*nov的帖子

我无法从文档中找到它,但目前似乎不支持Master-Master复制.它是否正确？

我有以下型号

class Owner(models.Model):
    user    = models.OneToOneField(User, default=1, editable=True)
    phone   = models.CharField(max_length=40, null=True, blank=True)
    address = models.CharField(max_length=255, null=True, blank=True)
    city    = models.CharField(max_length=255, null=True, blank=True)
    state   = USStateField(null=True, blank=True)
    zip     = models.CharField(max_length=20, null=True, blank=True)

    def __str__(self):
        return "%s %s" % (self.user.first_name, self.user.last_name)


class Device(CreationModificationMixin):

    _STATUSES = (
        ('A', 'Active'),
        ('I', 'Inactive'),
        ('F', 'Failure'),
    )

    _TYPES = (
        ('S', 'Spa'),
        ('P', 'Pool'),
    )

    udid    = models.CharField(max_length=255, verbose_name="Unique ID / MAC Address", null=False, blank=False, unique=True)
    type    = models.CharField(max_length=1, choices=_TYPES, null=False, blank=False)

我已使用TokenAuthentication启用了使用DRF的用户身份验证

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
         'rest_framework.authentication.TokenAuthentication',
         'rest_framework.authentication.SessionAuthentication'
    ),

        'rest_framework.serializers.ModelSerializer',
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.AllowAny',
    ),
    #'EXCEPTION_HANDLER': 'apps.core.exceptions.custom_exception_handler'

}

我有以下型号:

class Device(CreationModificationMixin):
    """
    Contains devices (WW controllers).  A device may be associated with the Owner
    """
    _STATUSES = (
        ('A', 'Active'), # when everything is okay

    )

    _TYPES = (

我在 Fedora25 上运行以下命令，期望将直播流传输到 youtube，同时将最终组合流（截屏 + 网络摄像头 + 徽标 + 音频）保存到本地mp4文件中。

ffmpeg \

.. seealso::

   Class :class:`apps.business.models.Department`
      Explanation goes here

   `GNU tar manual, Basic Tar Format <http://link>`_
      Documentation for tar archive files, including GNU tar extensions.

这会创建与班级部门的正确链接。

如何将 HTML 输出更改为只有一个类名称，而不带“apps.business.models ”前缀？

那么它在 HTML 中读取 Class Department 吗？

我该如何解决？ …

我已从 name.com 获得证书。

我是如何创造秘密的

我在 vpk.crt 文件末尾添加了 ca.crt 内容。

我正在 docker 镜像中构建。我的印象是，如果我安装，psycopg2-binary vs psycopg2我不应该安装额外的 postgresql 开发库。我错了吗？

我无法让酒店收集器工作，我是开放遥测技术的新手，所以感觉我在某个地方犯了一个愚蠢的错误

这是我的 python 示例脚本，它应该创建一个示例跟踪，该跟踪应该被导出，由 opentelemetry-collector 拾取并推送到 grafana tempo 后端

from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import (
    OTLPSpanExporter,
)
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import (
    BatchSpanProcessor,
    ConsoleSpanExporter,
)

span_exporter = OTLPSpanExporter(
   # endpoint="http://tempo.monitoring:3100"
   endpoint="10.120.4.111"
   # endpoint="http://10.120.7.235:4317"
)
provider = TracerProvider()
processor = BatchSpanProcessor(ConsoleSpanExporter())
span_processor = BatchSpanProcessor(span_exporter)
provider.add_span_processor(processor)
provider.add_span_processor(span_processor)
trace.set_tracer_provider(provider)


tracer = trace.get_tracer(__name__)

with tracer.start_as_current_span("foo"):
    with tracer.start_as_current_span("bar"):
        with tracer.start_as_current_span("baz"):
            print("Hello world from OpenTelemetry Python!")
