python - Django 中按降序排列类别

Question

我正在尝试为诊所创建一个个人资料，以便我可以向每个专业的医生展示。我想向最少医生展示最多医生的专业知识。

例如:

Dentists:
Names of all dentists (7)

Pediatricians
Names of pediatricians (4)

OB/GYN
Names of all obgyns (2)

模型.py

class Doctor(models.Model):
    name = models.CharField(max_length=1300)
    specialization = models.ForeignKey(Specialization, related_name = "doctor_specialization")
    sub_specialization = models.ForeignKey(Specialization, related_name = "doctor_subSpecialization", null = True, blank = True)
    clinic = models.ForeignKey(Clinic)

class Clinic(models.Model):
        name = models.CharField(max_length=500)
        slug = models.CharField(max_length=200, blank = True, null = True, unique = True)
        contact_no = models.IntegerField() 

class Specialization(models.Model):
    name = models.CharField(max_length=30)

View .py

def clinicProfile(request, slug):
    clinic = get_object_or_404(Clinic, slug=slug)
    doctors = Doctor.objects.all().order_by('-netlikes')

    d.update({'clinic': clinic, 'doctors': doctors, })

    return render(request, 'm1/clinicprofile.html', d)

Answer 1

很简单。不用 ('-netlikes')，只需使用 ('netlikes') 就可以了。您的函数应该如下所示。

 def clinicProfile(request, slug):
 clinic = get_object_or_404(Clinic, slug=slug)
 doctors = Doctor.objects.all().order_by('netlikes')
