I want to serve PDF document on my website using the django admin only. I am totally lost this is what i have as my model

class Examination(models.Model):
    examination_name = models.CharField(max_length=50)

    class Meta:
        verbose_name='examination'
        verbose_name_plural='examinations' 

    def __unicode__(self):
        return self.examination_name


# Create your models here.
class Year(models.Model):
    examinations = models.ForeignKey('Examination')
    examination_year = models.CharField(max_length=4)

    class Meta:
        verbose_name='year'
        verbose_name_plural='years'

    def __unicode__(self):
        return self.examination_year


class PastQuestion(models.Model):
    years = models.ForeignKey(Year)
    file = models.FileField(upload_to='uploads/', max_length=100,)
    posted_by = models.CharField(max_length=50)


    def __unicode__(self):
        return self.years
