1.圖書管理系統後端介面

1.1 books/models.py 中設定表

from django.db import models

class Books(models.Model):
    btitle = models.CharField(max_length=20)  # 標題
    bpub_date = models.DateField()  # 日期
    bread = models.IntegerField()  # 閱讀
    bcomment = models.IntegerField()  # 評論
    is_delete = models.BigIntegerField(default
 
=False) # 是否刪除

1.2 urls.py 中設定路由

from django.urls import path

from books import views

urlpatterns = [

    path('book/', views.BooksView.as_view()),
]

1.3 book/views.py 檢視函式

import json

from django.http import JsonResponse
from rest_framework.views import View

from .models import
 
 *


class BooksView(View):
    def get(self, request):
        books = Books.objects.filter(is_delete=False)
        book_list = books.values('id', 'btitle', 'bpub_date', 'bread', 'bcomment')
        book_list = list(book_list)
        data = {
            "code": 0,
            "msg": "success",
            
 
"books": book_list
        }
        return JsonResponse(data)

    def post(self, request):
        body_json = request.body.decode()
        body_dict = json.loads(body_json)
        btitle = body_dict.get('btitle')
        bpub_date = body_dict.get('bpub_date')
        bread = body_dict.get('bread')
        bcomment = body_dict.get('bcomment')

        book = Books(btitle=btitle, bpub_date=bpub_date, bread=bread, bcomment=bcomment)
        book.save()
        return JsonResponse({"code": 0, "msg": "success"})

    def put(self, request):
        body_json = request.body.decode()
        body_dict = json.loads(body_json)
        id = body_dict.get('id')
        btitle = body_dict.get('btitle')
        bpub_date = body_dict.get('bpub_date')
        bread = body_dict.get('bread')
        bcomment = body_dict.get('bcomment')

        book = Books.objects.get(id=id)
        book.btitle = btitle
        book.bpub_date = bpub_date
        book.bread = bread
        book.bcomment = bcomment
        book.save()
        return JsonResponse({"code": 0, "msg": "success"})

    def delete(self, request):
        body_json = request.body.decode()
        body_dict = json.loads(body_json)
        id = body_dict.get('id')

        book = Books.objects.get(id=id)
        book.is_delete = True
        book.save()
        return JsonResponse({"code": 0, "msg": "success"})
