articles > admin.py:

from django.contrib import admin
from articles.models import Article  # articles 앱의 Article 모델

admin.site.register(Article)

 

articles > models.py:

from django.db import models


class Article(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def __str__(self): # 모델 클래스 객체의 문자열 표현을 리턴

self.title

.accepted_renderer not set on Response
>>> you forgot to add the @api_view and the @renderer_classes decorator to your view.

 

/articles/index/

 

 

articles > views.py:

from rest_framework.response import Response
from rest_framework.decorators import api_view


@api_view(['GET'])
def index(request):
    return Response("연결 완료!")

 

api_view란? rest_framework에서 API를 간편하게 사용하게 하기 위한 브라우저블 API로

 

직접 브라우저에서 조작이 가능하게 해주고

 

돌려주는 response 또한 있는데 rest_framework.response

 

/articles/index/ - GET

/articles/index/ - GET, POST

db의 articles의 데이터 가져오기

 

articles > views.py:

from rest_framework.response import Response
from rest_framework.decorators import api_view
from articles.models import Article


@api_view(['GET'])
def index(request):
    articles = Article.objects.all()
    print(articles) # <QuerySet [<Article: hi>]>
    return Response(articles)

 

Object of type Article is not JSON serializable
>>> Response에 담을 수 있는 값은 string, dictionary, list

 

/articles/index/

 

def index(request):
    articles = Article.objects.all()
    article = articles[0]
    article_data = {
        'title': article.title,
        'content': article.content,
        'created_at': article.created_at,
        'updated_at': article.updated_at,
    }
    return Response(article_data)

 

/articles/index/
