REST API Django 不显示不同端点中的所有表

Question

我正在学习 REST API Django，感谢您的耐心等待并帮助理解以下案例。

在myproject/abcapp/forms.py

from django import forms
from .models import *

class ProfileForm(forms.ModelForm):
    class Meta:
        model=Profile
        fields = "__all__"
       
  
class Zoo_data_2020Form(forms.ModelForm):
    class Meta:
        model=Zoo_data_2020
        fields = "__all__"

在myproject/abcapp/models.py

from django.conf import settings
from django.db import models


class ProfileQuerySet(models.QuerySet):
    pass

class ProfileManager(models.Manager):
    def get_queryset(self):
        return ProfileQuerySet(self.model,using=self._db)


class Profile(models.Model):
    name=models.CharField(settings.AUTH_USER_MODEL,max_length=200) 
    subtype=models.CharField(max_length=500)
    type=models.CharField(max_length=500)
    gender=models.CharField(max_length=500)
  
    objects = ProfileManager()

    class Meta:
        verbose_name = 'Profile'
        verbose_name_plural = 'Profiles'

        managed = False
        db_table ='profiles'

    def __str__(self):
        return '{}'.format(self.name)
          
      
class Zoo_data_2020QuerySet(models.QuerySet):
    pass
  
class Zoo_data_2020Manager(models.Manager):
    def get_queryset(self):
        return Zoo_data_2020QuerySet(self.model,using=self._db)

class Zoo_data_2020(models.Model):
    name=models.CharField(max_length=200)
    size=models.DecimalField(decimal_places=3,max_digits=100000000)
    weight=models.DecimalField(decimal_places=3,max_digits=100000000)
    age=models.DecimalField(decimal_places=3,max_digits=100000000)
    
    objects = Zoo_data_2020Manager()

    class Meta:
        verbose_name = 'zoo_data_2020'
        verbose_name_plural = 'zoo_data_2020s'

        managed = False
        db_table ='zoo_data_2020'

    def __str__(self):
        return '{}'.format(self.name)

在myproject/abcapp/api/views.py中：

from rest_framework import generics, mixins, permissions
from rest_framework.views import APIView
from rest_framework.response import Response
import json
from django.shortcuts import get_object_or_404
from abcapp.models import *
from .serializers import *


def is_json(json_data):
    try:
        real_json = json.loads(json_data)
        is_valid = True
    except ValueError:
        is_valid = False
    return is_valid


class ProfileDetailAPIView(generics.RetrieveAPIView):
    
    permission_classes = []
    authentication_classes = []
    queryset= Profile.objects.all()
    serializer_class = ProfileSerializer
    lookup_field = 'id'


class ProfileAPIView(generics.ListAPIView):
    permission_classes = []
    authentication_classes= []
    serializer_class = ProfileSerializer

    passed_id = None
    search_fields = ('id','name','animal')
    queryset = Profile.objects.all()


    def get_queryset(self):
        qs = Profile.objects.all()
        query = self.request.GET.get('q')
        if query is not None:
            qs=qs.filter(name__icontains=query)
        return qs


  
class Zoo_data_2020DetailAPIView(generics.RetrieveAPIView):
    
    permission_classes = []
    authentication_classes = []
    queryset= Zoo_data_2020.objects.all()
    serializer_class = Zoo_data_2020Serializer
    lookup_field = ('id','name')
 

class Zoo_data_2020APIView(generics.ListAPIView):
    permission_classes =[]
    authentication_classes= []
    serializer_class = Zoo_data_2020Serializer

    passed_id = None
    search_fields = ('id','name')
    queryset = Zoo_data_2020.objects.all()


    def get_queryset(self):
        qs = Zoo_data_2020.objects.all()
        query = self.request.GET.get('q')
        if query is not None:
            qs=qs.filter(name__icontains=query)
        return qs

在myproject/abcapp/api/serializers.py中：

from rest_framework import serializers

from abcapp.models import *


class ProfileSerializer(serializers.ModelSerializer):
     class Meta:
        model=Profile
        fields = "__all__"
        
        read_only_fields = ['name']


class Zoo_data_2020Serializer(serializers.ModelSerializer):
     class Meta:
        model = Zoo_data_2020
        fields = "__all__"
        
        read_only_fields = ['name']

在myproject/abcapp/api/urls.py中：

from django.urls import path
from .views import *

urlpatterns = [
    path('', ProfileAPIView.as_view()),
    path('<id>/', ProfileDetailAPIView.as_view()),
    path('', Zoo_data_2020APIView.as_view()),
    path('<id>/', Zoo_data_2020DetailAPIView.as_view()),]

在myproject/urls.py中：

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/profile/', include('abcapp.api.urls')),
    path('api/zoodata2020/', include('abcapp.api.urls')),

]

所以当我调用 http://127.0.0.1:8000/api/profile/ 时，我从 table 的配置文件中获取数据，但是当我调用 http://127.0.0.1:8000/api/zoodata2020/ 时，我得到 数据再次来自 table 配置文件而不是 Zoo_data_2020。但是当我从 myproject/abcapp/api/urls.py 中删除时：

path('', ProfileAPIView.as_view()), path('<id>/', ProfileDetailAPIView.as_view()),

然后它向我显示来自 table Zoo_data_2020 的数据，但是我无法从 table 个人资料
中获取数据
如何解决？我确定我在应用程序和项目中的 urls.py 中都做错了。那么我需要做些什么才能使端点分开？以及如何同时显示它们？

我想调用 http://127.0.0.1:8000/api/profile/?search=TIGER and as result to give me information from both tables profiles and zoo_data_2020 as they contain different data but about the same 'name' which is TIGER. But currently when for example i call http://127.0.0.1:8000/api/profile/?search=TIGER 它只显示来自表格 Profile 的数据而不是来自 Zoo_data_2020

请帮助理解它以及如何修复它。提前致谢。

在项目 urls.py 中，您不必多次引用同一个应用程序，您可以在应用程序的 urls.py

中执行此操作

试试这个

myproject/urls.py:

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/', include('cfs.api.urls')),    
]

myproject/abcapp/api/urls.py:

urlpatterns = [
    path('profile', ProfileAPIView.as_view()),
    path('profile/<id>/', ProfileDetailAPIView.as_view()),
    path('zoo_data', Zoo_data_2020APIView.as_view()),
    path('zoo_data/<id>/', Zoo_data_2020DetailAPIView.as_view()),
]

REST API Django 不显示不同端点中的所有表

REST API Django does not show all tables in different endpoints

python

mysql
