"如何在 django 中修复循环？"

Question

我在 djano 中的循环有问题（也许我不明白这一点）。我在模板中有循环，它必须从数据库中输出值，但是我知道如何创建循环，它可以从（id = 1）输出值，因为这个一次又一次地循环输出值（id = 0）。

vds.html

{% for item in allobjects %}



  <div class="container-fluid">
        <div class="body2">
      <li class="title">{{item.title}}</li>
      <li class="listram">{{item.ram}}<small>ГБ(озу)</small></li>
      <img class="ram2"width="51px" height="49px" src="/static/main/images/ram.png" ></img>
      <li class="cpu">{{item.cpu}} vCore</li>
      <img class="cpu1"width="51px" height="50px"  src="/static/main/images/cpu.png" ></img>

视图.py

    servers = VDSTARIFS.objects.all() ##Maybe filter 
    context1 = {

更改您的views.py<\/code>以将id=1<\/code>的值返回为

def vds(request):
    servers = VDSTARIFS.objects.filter(id=1)
    context1 = {
        'allobjects': servers
    }
    return render(request, 'vds.html', context1)
