為什么模型沒有出現在 django 網站上
[英]Why the Models not showing up in django website
問題描述
我正在制作一個新聞網站，我制作了一個圖像、標題、描述、url（用於可點擊圖像）的模型，但最終輸出不僅顯示出來而且沒有錯誤。

您是同時使用allprojects和flashes在你的模板，但你將它們傳遞到不同的模板獨立意見。
目前尚不清楚（至少對我而言）這些視圖中的哪些對應於該模板。 我猜您正在嘗試使用techhome()視圖，因為您似乎無法顯示 Flash 數據。 你需要通過雙方allprojects和flashes的context ，以模板，使他們能夠進行渲染。 例如，如果您希望techhome()顯示兩者，您可以執行以下操作：
def techhome(request):
allprojects = AllProject.objects.all()
flashes = Flash.objects.all()
context = {'allprojects':allprojects, 'flashes':flashes}
return render(request, 'techworld/techhome.html', context)
為什么Django中的模型方法的返回值不顯示在模板中？
