如果你能帮助我,我将非常感激。如果你能提供一些资源来更好地理解这些概念,请提供。我已经通过了一些教程来达到这个阶段,但我现在被卡住了
干杯您可以更新
主页
的上下文
字典页面,将最新的\u公文包\u列表
传递到其模板
class HomePage(Page):
body = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('body', classname="homepage"),
]
def get_context(self, request):
context = super(HomePage, self).get_context(request)
context['latest_portfolio_list'] = PortfolioPage.objects.live()
return context
然后在主页模板中循环查看lastest\u portfolio\u列表
class HomePage(Page):
body = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('body', classname="homepage"),
]
def get_context(self, request):
context = super(HomePage, self).get_context(request)
context['latest_portfolio_list'] = PortfolioPage.objects.live()
return context
参考:
“PortfolioPage”对象不可编辑>错误。有什么想法吗?如果传递单个项目,您不需要模板中的循环。您可以在模板上下文中将此项目作为最后一个项目组合
传递,并直接访问它
再次感谢您。花了几分钟的时间来解决它,但它已经排序好了!您太棒了!
