Question

有人可以帮忙吗？

我想从数据库中打印一些计数（总记录中，完整字段= true，而另一个则为false。

下面我做错了什么？

谢谢

function myFunction() {
  var i, dicepic;
  var itotal = ktotal = ltotal = jtotal = totalgeral = 0;
  var dice = Math.floor(Math.random() * 1000) + 1;

  for (i = 0; i < dice; i++) {
    itotal++;
    totalgeral++;

    var k;
    for (k = 1; k < 7; k++) {
      ktotal++;
      totalgeral++;
      document.getElementById("first-picture" + k).src = 'images/empire.jpg';
    }

    var l;
    for (l = 1; l < 7; l++) {
      ltotal++;
      totalgeral++;
      document.getElementById("first-picture" + l).src = 'images/black.jpg';
    }

    var j;
    for (j = 1; j < 7; j++) {
      jtotal++;
      totalgeral++;
      var dicepic = Math.floor(Math.random() * 11) + 1;
      document.getElementById("first-picture" + j).src = 'images/image' + dicepic + '.jpg';
      document.getElementById("vari1").innerHTML = "Value of i is: " + i;
      document.getElementById("vari2").innerHTML = "Value of Dice is: " + dice;
      document.getElementById("pic-code-" + j).innerHTML = "Code is: " + dicepic;
    }
  }

  document.getElementById("vari3").innerHTML = "Value of Dice is: " + dice;
  document.getElementById("loop-i").innerHTML = "Loop I: " + itotal;
  document.getElementById("loop-k").innerHTML = "Loop K: " + ktotal;
  document.getElementById("loop-l").innerHTML = "Loop L: " + ltotal;
  document.getElementById("loop-j").innerHTML = "Loop J: " + jtotal;
  document.getElementById("loops-total").innerHTML = "Total: " + totalgeral;

def task_count(request):
    completetasks = Todo.objects.filter(complete=True).count()
    incompletetasks = Todo.objects.filter(complete=False).count()
    return render(request, 'counts.html')

COUNTS.HTML

urlpatterns = [
    url(r'^$', views.todo, name='index'),
    url(r'^create/$', views.create_task, name='create'),
    url(r'^counts/$', views.task_count, name='counts'),

在您的视图文件中这样更改

def task_count(request):
    completetasks = Todo.objects.filter(complete=True).count()
    incompletetasks = Todo.objects.filter(complete=False).count()
    context = {
        'completetasks': completetasks,
        'incompletetasks': incompletetasks
    }
    return render(request, 'counts.html', context)

然后在counts.html

{{ completetasks }}
{{ incompletetasks }}

将数据库值打印到html django
