Django 1.6:按布尔和喜欢对对象进行排序

Question

我有一个医生模型,我正在显示基于最喜欢的医生对象.如果医生是否获得赞助,我会为每位医生提供一个布尔字段.我想首先向赞助医生展示,然后根据最喜欢的人对其余的医生进行分类.

这是我要按netlikes排序的,它正在工作

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

我试过这个,但没有任何区别

doctors = Doctor.objects.all().order_by('sponsored').order_by('-netlikes')

医生model.py

class Doctor(models.Model):
    name = models.CharField(max_length=1300)
    title = models.CharField(max_length=1300, null = True, blank = True)
    specialization = models.ForeignKey(Specialization)
    clinic = models.ForeignKey(Clinic)
    education1 = models.CharField(max_length=1300)
    gender_choices = ( ('Male', 'Male'), ('Female','Female'),)
    gender = models.CharField(max_length=15, choices = gender_choices, null=True, blank = True)
    image = models.ImageField(upload_to='uploads/', null=True, blank = True)
    likes = models.IntegerField(default=0)
    dislikes = models.IntegerField(default=0)
    netlikes = models.IntegerField(default=0)
    submitted_on = models.DateTimeField(auto_now_add=True, null = True, blank = True)
    sponsored = models.BooleanField(default = False)

关于我如何首先展示赞助医生然后最高的喜欢？

Answer 1

你不能order_by在django中链接,最后一个会覆盖以前的所有排序.为了避免它,只需使用

doctors = Doctor.objects.all().order_by('sponsored', '-netlikes')
