Question

如何在 django-rest-framework 下拉列表中看到主题名称？现在它只是说 Subject object.

这是我的模型：

class Subject(models.Model):
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    owner = models.ForeignKey('auth.User', related_name='subjects')
    code = models.CharField(max_length=50)
    name = models.CharField(max_length=50)
    description = models.CharField(max_length=50)

    class Meta:
        ordering = ('created',)

    def __unicode__(self):
        return '%s' % (self.name)

class Grade(models.Model):
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    owner = models.ForeignKey('auth.User', related_name='grades')

    code = models.CharField(max_length=3)
    requirements = models.CharField(max_length=200)
    ranking = models.IntegerField()

    subject = models.ForeignKey(Subject, related_name='grades', on_delete=models.CASCADE)

    class Meta:
        unique_together = ('subject', 'ranking')
        ordering = ('ranking',)

    def __unicode__(self):
        return '%d: %s' % (self.ranking, self.code)

Answer 1

我看到您已经为您的模型定义了 __unicode__。但也许您正在使用 Python 3，在这种情况下，对于 Django 模型，您需要定义 __str__ 而不是 __unicode__

class Subject(models.Model):
    ...

    def __str__(self):                # Use this in Python 3
        return '%s' % (self.name)

无关，但这个更简洁return:

    def __str__(self):
        return self.name
