这是我的模型:

class Claim(models.Model):
def __str__(self):              
    return self.claim_id
policy = models.ForeignKey(Policy);
claim_id = models.CharField(max_length=50, unique=True, db_index=True);
loss_dt = models.DateTimeField();
loss_location = models.CharField(max_length=100);
clam_stat = models.CharField(max_length=2, default='open');
cas_aia_cds_1_2 = models.CharField(max_length=50);
cas_aia_cds_3_4 = models.CharField(max_length=50);
reported_dt = models.DateTimeField();
loss_desc = models.TextField();
class Meta:
    ordering = ['-loss_dt','reported_dt']

在views.py中:

  def home(request):
try:
    claims = m.Claim.objects.all()
    claims_list = []

    for c in claims:
        claims_list.append(c.loss_desc)

    context = RequestContext(request, {
        'claim_list': claims_list
    })
    return render_to_response(request, 'home.html', context_instance=context)
except m.Claim.DoesNotExist:
    raise Http404

我想做的是将声明对象列表发送到模板。
任何想法将不胜感激。

render_to_response 不接受 request 作为参数。

将其删除,其余保持原样。
