为什么这些模特没有出现在django网站上
为什么这些模特没有出现在django网站上
提问于 2020-10-29 03:33:43
我正在制作一个新闻网站，我做了一个模型的图像，标题，描述，url(可点击的图像)，但最终的输出不只是显示和没有错误。
还请查看我附加的输出屏幕截图和管理页面截图的图片链接

您在模板中同时使用了allprojects和flashes，但是可以将它们在单独的视图中传递给不同的模板。
不清楚(至少对我来说)这些视图中哪些与此模板相对应。我猜您正在尝试使用techhome()视图，因为您似乎无法获得闪存数据。您需要将allprojects和flashes作为context传递给模板，这样就可以呈现它们。例如，如果希望techhome()同时显示两者，则可以执行以下操作：
def techhome(request):
allprojects = AllProject.objects.all()
flashes = Flash.objects.all()
context = {'allprojects':allprojects, 'flashes':flashes}
return render(request, 'techworld/techhome.html', context)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
