初学者render字典参数传递
自己琢磨了一下，把字典参数分别命名了，便于理解页面跳转顺序，给大家参考一下。
urls.py
urlpatterns = [ url(r'^index/', views.index), url(r'^article/(?P<article5_id>[0-9]+)$', views.article_page,name='article_page'), url(r'^edit/(?P<article4_id>[0-9]+)$', views.edit_page,name='edit_page'), url(r'^edit/action$', views.edit_action,name='edit_action'), ]
views.py
def index(request):
articles=models.Article.objects.all()
return render(request, 'blog/index.html',{'article1':articles})
def article_page(request,article5_id):
article=models.Article.objects.get(pk=article5_id)
return render(request,'blog/article_page.html',{'article2':article})
def edit_page(request,article4_id):
if str(article4_id)=='0':
return render(request,'blog/edit_page.html')
article = models.Article.objects.get(pk=article4_id)
return render(request,'blog/edit_page.html',{'article3':article})
def edit_action(request):
title=request.POST.get('title','TITLE')
content=request.POST.get('content','CONTENT')
article1_id=request.POST.get('article7_id','0')
if article1_id=='0':
models.Article.objects.create(title=title,content=content)
articles=models.Article.objects.all()
return render(request, 'blog/index.html',{'article1':articles})
article6=models.Article.objects.get(pk=article1_id)
article6.title=title
article6.content=content
article6.save()
return render(request,'blog/article_page.html',{'article2':article6})index.html
