延續文章：在pythonanywhere設計Django網站的卡片(Card)功能(新增For Template)
1.定義資料庫
1 2 3 4 5 6 7 8 9 10 11 | from django.db import models
# Create your models here.
class vegetableDB(models.Model):
image = models.CharField(max_length = 20, null = False)
title = models.CharField(max_length = 20, blank = True, default='')
subtitle = models.CharField(max_length = 20, blank = True, default='')
def __str__(self):
return self.image
|
2.修改mysite/myapp/views.py
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | from django.shortcuts import render from myapp.models import vegetableDB # Create your views here. def index(request): slide1 = {'image':'fruits01.jpg', 'active':'active', 'interval':'10000', 'title':'水果01', 'subtitle':'好水果在雲林'} slide2 = {'image':'fruits02.jpg', 'active':'', 'interval':'2000', 'title':'水果02', 'subtitle':'好水果在雲林'} slide3 = {'image':'fruits03.jpg', 'active':'', 'interval':'3000', 'title':'水果03', 'subtitle':'好水果在雲林'} slides = [slide1, slide2, slide3] return render(request, 'index.html', locals()) def vegetable(request): vegetables = vegetableDB.objects.all().order_by('id') return render(request, 'vegetable.html', locals()) def fruit(request): return render(request, 'fruit.html', locals()) |
3.重新Reload並執行，但發生錯誤，是因為沒有資料庫
4. 開啟Bash，下達 python manage.py makemigrations
5.修改mysite/mysite/settings.py，把static拿掉。

python manage.py makemigrations
python manage.py migrate
7.執行後發現蔬菜內的照片全部不見，這是因為資料庫內沒有任何資料。
8.建立超級使用者
python manage.py createsuperuser
9.登入後台
cmlin.pythonanywhere.com/admin
在下圖依然沒有看到資vegetableDB資料
1 2 3 4 5 6 7 8 9 | from django.contrib import admin from myapp.models import vegetableDB # Register your models here. class vegetableAdmin(admin.ModelAdmin): list_display=('id', 'image', 'title', 'subtitle') admin.site.register(vegetableDB, vegetableAdmin) |
11.在後台新增一筆資料
12.重新載入
