在我的项目中,我使用django rest框架.要过滤结果,我使用django_filters后端.有我的代码:

models.py

from django.db import models


class Region(models.Model):
    name = models.CharField(max_length=100, blank=True, null=False)


class Town(models.Model):
    region = models.ForeignKey(Region)
    name = models.CharField(max_length=100, blank=True, null=False')

filters.py

import django_filters
from models import Town


class TownFilter(django_filters.FilterSet):
    region = django_filters.CharFilter(name="region__name", lookup_type="contains")
    town = django_filters.CharFilter(name="name", lookup_type="contains")

    class Meta:
        model = Town
        fields = ['region', 'town']

views.py

from models import Town
from rest_framework import generics
from serializers import TownSerializer
from filters import TownFilter


class TownList(generics.ListAPIView):
    queryset = Town.objects.all()
    serializer_class = TownSerializer
    filter_class = TownFilter

所以,我可以将？region …

我知道Celery worker可以接收消息协议v2格式的消息。该协议通过lang标头支持多种语言：

...
application_headers={
    'lang': 'py',
    'task': 'proj.tasks.add',
    ...
}
...

在书面文档中，工作人员可以将消息重定向到支持该语言的工作人员，并且没有有关如何以Java，PHP等编写工作人员或任务的信息。
