Django部落格修改文章
阿新 • • 發佈：2018-12-02
一 思路
新文章為空，修改文章有內容
修改文章頁面有文章物件
通過文章的ID區分：0為新文章，其他為修改文章
二 修改資料方法
article.title = title
article.save()
三 程式碼
1 blog/views.py
from django.shortcuts import render from django.http import HttpResponse from . import models def index(request): articles = models.Article.objects.all() return render(request, 'blog/index.html',{'articles': articles}) def article_page(request,article_id): article = models.Article.objects.get(pk=article_id) return render(request,'blog/article_page.html',{'article':article}) def edit_page(request,article_id): if str(article_id) == '0': return render(request,'blog/edit_page.html') article = models.Article.objects.get(pk=article_id) return render(request, 'blog/edit_page.html', {'article': article}) def edit_action(request): title = request.POST.get('title', 'TITLE') content = request.POST.get('content', 'CONTENT') article_id = request.POST.get('article_id', '0') # 新增文章 if article_id == '0': models.Article.objects.create(title=title,content=content) articles = models.Article.objects.all() return render(request, 'blog/index.html', {'articles': articles}) # 修改文章 article = models.Article.objects.get(pk=article_id) article.title = title article.content = content article.save() return render(request, 'blog/article_page.html', {'article': article})
2 blog/urls.py
from django.conf.urls import url, include from . import views urlpatterns = [ url(r'^index/$', views.index), url(r'^article/(?P<article_id>[0-9]+)$', views.article_page, name='article_page'), url(r'^edit/(?P<article_id>[0-9]+)$', views.edit_page,name='edit_page'), url(r'^edit/action$', views.edit_action,name='edit_action'), ]
