如何在django admin中填充外键中的数据

Question

class LogCall(models.Model):
    customer = models.ForeignKey(Company, verbose_name=_('Company '))
    date = models.DateTimeField(verbose_name=_('Date Call '), default=datetime.now())
    duration = models.CharField(verbose_name=_('Duration '), max_length=100, default='00:00:00 ')
    category = models.CharField(verbose_name=_('category '), max_length=100, choices=categoryCall, default=2)
    priority = models.CharField(verbose_name=_('Priority '), max_length=100, choices=priorityCall, default=2)
    summary = models.CharField(verbose_name=_('summary '), max_length=100, )
    status = models.CharField(verbose_name=_('Status '), max_length=100, choices=statusCall,
                              default=2)    

class Log_list(models.Model):
    log_reff = models.ForeignKey(LogCall, verbose_name=_('Source'))
    customer = models.CharField(verbose_name=_('Customer'), max_length=100)
    summary = models.CharField(verbose_name=_('Summary'), max_length=100)
    status = models.CharField(verbose_name=_('Status'), max_length=100, choices=statusCall)

我想根据更改选项字段foreignkey从模型LogCall中的数据自动填充到模型Log_list。 可以帮我？？我是django的新手
