Django 1.6 Cant在模板中显示模型中的多个字段

Question

我正在尝试在模板中显示医生模型的众多字段。 每个医生都有不只一种语言。 因此，我试图显示与每个医生相关的语言。 我的问题是它什么也没给我显示

这是我要显示的模板

 {% for a in doctor.languages.all %}
            <p>{{a}}</p>
        {% endfor %}

这是models.py

class Language(models.Model):
    '''
    a = "English"
    b = "Arabic"
    c = "Hindi"
    d = "Urdu"
    e = "Bengali"
    f = "Malayalam"
    g = "French"
    h = "Spanish"
    '''
    name = models.CharField(max_length=200)
    def __unicode__(self):
        return self.name

class Doctor(models.Model):
    name = models.CharField(max_length=30)
    specialization = models.ForeignKey(Specialization)
    clinic = models.ForeignKey(Clinic)
    seekers = models.ManyToManyField(DoctorSeeker, through='Review')
    language = models.ManyToManyField(Language)
    education1 = models.CharField(max_length=100)
    education2 = models.CharField(max_length=100, null = True)
    gender_choices = ( ('M', 'Male'), ('F','Female'),)
    gender = models.CharField(max_length=5, choices = gender_choices, null=True)
    profile_pic = models.ImageField(upload_to='uploads/', null=True)
    statement = models.TextField(null=True)
    affiliation = models.CharField(max_length=100, null = True)

    def __unicode__(self):
      return u"%s %s" % (self.name, self.specialization)

Answer 1

该字段称为language ，而不是languages ：

{% for a in doctor.language.all %}
    <p>{{ a }}</p>
{% endfor %}
