我在数据库中创建了一个模型和两个值。第一个是西里尔字母,第二个是拉丁文。
from __future__ import unicode_literals
from django.db import models
class Lecturer(models.Model):
fname = models.CharField('First name', max_length=200)
mname = models.CharField('Middle name',max_length=200)
lname = models.CharField('Last name', max_length=200)
pub_date = models.DateTimeField('Date published')
def __str__(self):
return "{} {} {}" .format(self.fname, self.mname, self.lname)
但是当我尝试点击链接并编辑西里尔字母值时,出现错误。

最佳答案
要在 Python 2.7 中通过 __unicode__
使用 __str__
方法,请使用提供的 python_2_unicode_compatible装饰者:
from __future__ import unicode_literals
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
@python_2_unicode_compatible
class Lecturer(models.Model):
fname = models.CharField('First name', max_length=200)
mname = models.CharField('Middle name',max_length=200)
lname = models.CharField('Last name', max_length=200)
pub_date = models.DateTimeField('Date published')
def __str__(self):
return "{} {} {}" .format(self.fname, self.mname, self.lname)
否则你将不得不使用 __unicode__
而不是 __str__
。
