Django系列：开发自己的RestAPI

1、项目结构

2、models

init.py

from .BookModel import Book

BookModel

from django.db import models


class Book(models.Model):
    b_name = models.CharField(max_length=32)
    b_price = models.FloatField(default=1)

    def to_dict(self):
        return {'id': self.id, 'b_name': self.b_name, 'b_price': self.b_price}

3、views

init.py

from .BookAPI import book, books

BookAPI.py

from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt

from Api.models import Book

@csrf_exempt
def books(request):
    if request.method == "GET":
        book_list = Book.objects.all()

        book_list_json = []

        for book in book_list:
            book_list_json.append(book.to_dict())

        data = {
            'status': 200,
            'msg': 'ok',
            'data': book_list_json
        }

        return JsonResponse(data=data)

    elif request.method == "POST":
        b_name = request.POST.get('b_name')
        b_price = request.POST.get('b_price')

        book = Book()
        book.b_name = b_name
        book.b_price = b_price
        book.save()

        data = {
            'status': 201,
            'msg': 'add success',
            'data': book.to_dict()
        }

        return JsonResponse(data=data, status=201)


@csrf_exempt
def book(request, bookid):
    if request.method == "GET":
        book_obj = Book.objects.get(pk=bookid)

        data = {
            'msg': 'ok',
            'status': 200,
            'data': book_obj.to_dict()
        }

        return JsonResponse(data=data)
    elif request.method == "DELETE":

        book_obj = Book.objects.get(pk=bookid)

        book_obj.delete()

        data = {
            'msg': 'delete success',
            'status': 204,
            # 'data': {}
        }

        return JsonResponse(data=data, status=204)

4、urls.py

from django.conf.urls import url

from Api import views

urlpatterns = [
    url(r'^books/$', views.books, name='books'),
    url(r'^books/(?P\d+)/', views.book, name='book'),
]

5、static->>CreateBook.html

    
    
    
    



    


        


            BookName： 
            

            BookPrice: 

        

        Create

    

6、static->>BookList.html
