Scrapy学习第九课

目标：搭建类似博客的简单页面

实例：具体代码如下

1、view.py

from django.shortcuts import render
from django.http import HttpResponse

from . import models

def home(request):
    articles = models.Articles.objects.all()
    return render(request, 'learn/home.html', {'articles':articles})


def article_page(request, article_id):
    article = models.Articles.objects.get(pk = article_id)
    return render(request, 'learn/article_page.html', {'article': article})

def edit_page(request, article_id):
    if str(article_id) == '0':
        return render(request,'learn/edit_page.html')
    article = models.Articles.objects.get(pk = article_id)
    return render(request, 'learn/edit_page.html', {'article': article})

def edit_action(request):
    title = request.POST.get('title', 'TITLE')
    content= request.POST.get('content', 'CONTENT')
    id = request.POST.get('id','ID')
    if not id:
        models.Articles.objects.create(title=title, content = content)
    else:
        models.Articles.objects.filter(id=id).update(title=title,content=content)
    
    articles = models.Articles.objects.all()
    return render(request, 'learn/home.html', {'articles':articles})

知识点：

1、测试在python3.7版本下，命令行输入python manage.py shell 进入的界面如下，非以前版本式的命令行解释器

但是同样可以与数据库交互：
