Django Unicode无法正常工作

Question

im newbie at Python writing, and I'm trying to set up my database to manage it in django admin panel. My problem is that when i define unicode it's not working and I don't know why.

class Doors(models.Model):
door_uid = models.IntegerField(primary_key=True)
door_owner = models.IntegerField()
door_ownertype = models.IntegerField()
door_name = models.CharField(max_length=32)

  class Meta:
    verbose_name = 'Drzwi'
    verbose_name_plural = 'Drzwi'
    managed = True
    db_table = 'hrp_doors'

    def __unicode__(self):
        return self.door_uid

after doing it, it still shows 'HrpDoors object'. What am I doing wrong?

Answer 1

Not sure about why you get an HrpDoors object.

You may have an indentation problem. Also your unicode function is returning an integer:

class HrpDoors(models.Model):
    door_uid = models.IntegerField(primary_key=True)
    ...

    class Meta:
        ...

    def __unicode__(self):
        return unicode(self.door_uid)

Answer 2

In your case, the __unicode__ attribute is a method of class Meta where as it should be for HrpDoors

Try this:

class HrpDoors(models.Model):
    door_uid = models.IntegerField(primary_key=True)
    door_owner = models.IntegerField()
    door_ownertype = models.IntegerField()
    door_name = models.CharField(max_length=32)

    class Meta:
        verbose_name = 'Drzwi'
        verbose_name_plural = 'Drzwi'
        managed = True
        db_table = 'hrp_doors'

    def __unicode__(self): #Look at the indentation of unicode - same level as attributes of class model
        return u'%s' % self.door_uid #Also, return unicode explicitly
