如何正确记录查询参数（搜索，过滤）Django Rest Framework？

Question

我是DRF渲染文档的新手。我不明白如何正确地在代码中对其进行文档化以呈现文档中的描述。我正在使用DRF文档。

例如：我有可以检索一些数据的路线。在相关视图中，我有：

search_fields = ('name', 'registration_date')

但是这些字段在文档页面上没有描述。 。

所以我想为他们添加描述。有办法吗？

Answer 1

概括

DRF 文档中有三种类型的描述（正如我所尝试的），它们依赖于两个位置的设置。

• 类型1：路径参数描述->在模型字段定义处设置
• 类型2：查询参数描述->在特定字段的过滤器定义中设置
• 类型 3：请求正文描述 -> 与类型 1 相同

类型 1 和类型 3 描述的模型字段定义

# my_project/my_app/models.py
from django.db import models
from django.utils.translation import gettext_lazy as _

class MyModel(models.Model):
    id = models.BigAutoField(primary_key=True, help_text=_("Field id - This will show up in DRF docs Path Parameter Description/Request Body Description, '_' meaning using django translation module"))
    field1 = models.IntegerField(help_text=_("Field field1 - This will show up in DRF docs Path Parameter Description/Request Body Description, '_' meaning using django translation module"))

用于类型 2 描述的特定字段定义的搜索过滤器

# my_project/my_app/filters.py
from rest_framework import filters

class MyFilter(filters.SearchFilter):
    search_param = 'field1'
    search_title = 'Exact matches Field1' # Shows up in DRF docs interactive query pop-up menu as the title for the query section of the field1
    search_description = 'This will show up in DRF docs Query Parameter Description'

序列化器和 ViewSet 配置

# my_project/my_app/serializers.py
from rest_framework import serializers

from my_app.models import MyModel

class MySerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

# my_project/my_app/views.py
from rest_framework import viewsets

from my_app.models import MyModel
from my_app.serializers import MySerializer
from my_app.filters import MyFilter

class MyViewSets(viewsets.ModelViewSet):
    queryset = MyModel.objects.all()
    serializer_class = MySerializer
    filter_backends = [MyFilter]
    search_fields = ['=field1', '@field1']
        # The first charactor '='/'^' is used by SearchFilter.filter_queryset while doing
        # the SearchFilter.construct_search method
        # and '=' for exact match while '^' for starts with search
        # One could get all options at rest_framework.filters.SearchFilter.lookup_prefixes
        # BTW my rest_framework version is djangorestframework==3.11.1

最后是 url 和设置配置

# my_project/my_app/urls.py
from django.urls import path, include
from rest_framework import routers

from my_app.views import MyViewSets

router = routers.DefaultRouter()
router.register('test', MyViewSets)

urlpatterns = [
    path('', include(router.urls))
]

# my_project/my_project/urls.py
from django.urls import path, include
from rest_framework.documentation import include_docs_urls

urlpatterns = [
    path('docs/', include_docs_urls('API Documentaion')),
    path('my_app/', include('my_app.urls'))
]
