一些用户是有“任务”的“编码员”。

class Coder(models.Model):
    """Every user can be a coder. Coders are assigned to Assignments"""
    user = models.OneToOneField(User, related_name='coder')

def __unicode__(self):
    return self.user.username

class Assignment(models.Model):
    """An assignment covers a range of years, 
    has multiple coders and one specific task"""
    title = models.CharField(blank=True, max_length=100)
    start_date = models.DateField(default=datetime.datetime.today)
    end_date = models.DateField(default=datetime.datetime.today)
    country = models.ForeignKey(Country, default=1, related_name='assignments')
    coders = models.ManyToManyField(User, related_name='assignments')
    screening = models.BooleanField(default=False)
    classifying = models.BooleanField(default=False)

def __unicode__(self):
    return self.country

如果编码员已登录，我如何向他们展示已分配给他们的所有作业？
以下视图不起作用，它给了我“'Coder' 对象没有属性'assignments'”。

def user_view(request):
    if request.user.is_authenticated():
        assignments = request.user.coder.assignments.all()
    else:
        pass
    return render(request, 'account.html')

为什么这不起作用？我怎样才能让它工作？

使用request.user.coder.assignments.all().

您没有在调用中传递任务来渲染
