1. fcuser의 admin.py 구성

from django.contrib import admin
from .models import Fcuser

# Register your models here.


class FcuserAdmin(admin.ModelAdmin):
    # list_display는 튜플 형식으로서 전달하기 때문에 마지막에 꼭 ,를 붙여줘야 한다
    list_display = ('email',)


admin.site.register(Fcuser, FcuserAdmin)

2. order의 admin.py 구성

from django.contrib import admin
from .models import Order

# Register your models here.


class OrderAdmin(admin.ModelAdmin):
    list_display = ('fcuser', 'product',)


admin.site.register(Order, OrderAdmin)

3. product의 admin.py 구성

from django.contrib import admin
from .models import Product

# Register your models here.


class ProductAdmin(admin.ModelAdmin):
    list_display = ('name', 'price',)


admin.site.register(Product, ProductAdmin)

4. superuser 만들기

python manage.py createsuperuser

    description = models.TextField(verbose_name='상품설명')
    stock = models.IntegerField(verbose_name='재고')
    register_date = models.DateTimeField(
        auto_now_add=True, verbose_name='등록날짜')

    def __str__(self):
        return self.name

    class Meta:
        db_table = 'fastcampus_product'

04. order의 models.py 수정

from django.db import models

# Create your models here.


class Order(models.Model):
    # 어떤 사용자가 어떤 제품을 주문하기에 외래키인 ForeignKey가 필요
    # fcuser안에 있는 Fcuser라는 클래스를 불러온다!
    # ForeignKey를 사용할 때는 on_delete를 꼭 설정해줘야 한다(사용자가 삭제되었을 때 주문 데이터는 어떻게 처리할지)
    # on_delete=models.CASCADE로 설정하게 되면 사용자가 삭제되면 주문 데이터도 같이 삭제된다
    fcuser = models.ForeignKey(
        'fcuser.Fcuser', on_delete=models.CASCADE, verbose_name='사용자')
    product = models.ForeignKey(
        'product.Product', on_delete=models.CASCADE, verbose_name='상품')
    quantity = models.IntegerField(verbose_name='수량')
    register_date = models.DateTimeField(
        auto_now_add=True, verbose_name='등록날자')

    def __str__(self):
        return str(self.fcuser) + ' ' + str(self.product)

    class Meta:
        db_table = 'fastcampus_order'
        verbose_name = '주문'
        verbose_name_plural = '주문'
