以 10 为底的 int() 的无效文字：'John Doe'

Question

我有一个模型病人和另一个检查，现在我想根据名字检索病人的检查，但是我被错误的 int() 以 10: 'John Doe' 为底的无效文字所覆盖

这是我的看法

def see_exam(request, name):
    exam = Test.objects.filter(patient__user__exact=name)

    context = {
        'exam' : exam
    }

    return render(request, 'account/labtechs/see_results.html', context)

模型考试

class Test(models.Model):
    exam = models.ForeignKey(Exam)
    patient = models.ForeignKey(Patient)
    date = models.DateField()
    result = models.TextField(default="negative")
    done_by = models.CharField(max_length=120)
    def __unicode__(self):
        return self.exam.name

患者模型

class Patient(models.Model):
    """docstring for Patient"""
    user = models.OneToOneField(MyUser)
    date_of_birth = models.DateTimeField(blank=True, null=True)
    age = models.IntegerField(default=1)
    sex = models.OneToOneField(Sex)
    religion = models.CharField(max_length=120, blank=True, null=True)
    village = models.CharField(max_length=120)
    status = models.OneToOneField(Status, blank=True, null=True)
    relative = models.CharField(max_length=120)
    phone = models.IntegerField(default=1)
    allergies = models.TextField(default="", blank=True, null=True)
    defficiencies = models.TextField(default="", blank=True, null=True)
    created_at = models.DateTimeField(auto_now=True)
    updated_at = models.DateTimeField(auto_now_add=True)
    def __unicode__(self):
        return "%s %s" %(self.user.first_name, self.user.last_name)

Answer 1

更改查询

exam = Test.objects.filter(patient__user__exact=name)

到

exam = Test.objects.filter(patient__user__name__exact=name)
#------------------------------------------^

注意添加的user__name。在这里，我假设您的 MyUser 类具有您要比较的属性 name。

在您的查询中，您尝试将字符串 name 与不兼容的对象 user（或者更确切地说该对象的内部 id）进行比较。
