當列表對象

Question

我在models.py一類病人與

class Patient(models.Model): 
     cpf_id = models.CharField(null=True, blank=True, max_length=15, unique=True, validators=[validate_cpf]) 
     rg_id = models.CharField(max_length=15, null=True, blank=True) 
     name_txt = models.CharField(max_length=50) 
     number_record = models.AutoField(primary_key=True) 
     medical_record_number = models.CharField(max_length=25, null=True, blank=True) 
     natural_of_txt = models.CharField(max_length=50, null=True, blank=True) 
     citizenship_txt = models.CharField(max_length=50, null=True, blank=True) 
     street_txt = models.CharField(max_length=50, null=True, blank=True) 

     class Meta: 
      permissions = (
       ("view_patient", "Can view patient"), 
      ) 

     def __unicode__(self): # Python 3: def __str__(self): 
      return \ 
       self.name_txt, self.cpf_id, self.rg_id, self.medical_record_number,            self.natural_of_txt, \ 
       self.citizenship_txt, self.street_txt 

當我屬性的所有對象的變量或過濾器，使用例如某些對象的Django蟒誤差，

patient = Patient.objects.all() 

好的，沒有消息錯誤。

但是當我嘗試列表這個對象，我收到以下消息錯誤

Traceback (most recent call last): 
    File "<console>", line 1, in <module> 
    File "/usr/local/lib/python2.7/dist-packages/django/db/models/query.py", line 74, in  __repr__ 
    return repr(data) 
    File "/usr/local/lib/python2.7/dist-packages/django/db/models/base.py", line 423, in  __repr__ 
    u = six.text_type(self) 
TypeError: coercing to Unicode: need string or buffer, tuple found 

編輯：

發生時的代碼，當我在外殼位

>>> patient 

列出對象我創建了

>>>> patient = Patient.objects.all()

__unicode__()應該返回一個字符串，而不是元組：

def __unicode__(self): 
    return self.name_txt
