Question

我列出了具有相似属性的医生。我想根据他们喜欢的数量按降序在我的模板中列出它们。

这是我需要展示的模板

{% for doc in doctors %}
                <h2><a href="/docprofile/{{doc.id}}/">{{doc.name}}</a></h2>
                <h3> {{doc.specialization}}</h3>
                <h4> {{doc.clinic.name}}</h4>
                <h4> {{doc.clinic.address}}</h4>

                <div class="like">
                  <img class="like" src="/static/meddy1/images/like.png">
                  <p>{{doc.likes}}</p>
                </div>

       {% endfor %}
      </div>
    </div>

这是我的views.py

@csrf_exempt
def doclistings(request):
    d = getVariables(request)
    doctors = Doctor.objects.all()

    paginator = Paginator(doctors, 20) #Show 20 doctors per page
    page =  page = request.GET.get('page')
    try:
        doctors = paginator.page(page)
    except PageNotAnInteger:
        doctors = paginator.page(1)
    except EmptyPage:
        doctors = paginator.page(paginator.num_pages)
    d['doctors'] = doctors
    d['paginator'] = paginator

    return render_to_response('meddy1/doclistings.html',d)

Answer 1

使用order_by()：

doctors = Doctor.objects.all().order_by('-likes')

您还可以在Model Meta类中定义default ordering：

class Doctor(models.Model):
    class Meta:
        ordering = ['-likes']
