我有一个模型,它模拟了一条多达30个车站的列车线,因此该模型有30个可空字段。
模型.py
class TempLine(models.Model):
picking_mode = models.IntegerField(default=1)
start_station = models.CharField(max_length=2000)
end_station = models.CharField(max_length=2000, null=True)
station_1 = models.CharField(max_length=2000, null=True)
station_2 = models.CharField(max_length=2000, null=True)
station_3 = models.CharField(max_length=2000, null=True)
station_4 = models.CharField(max_length=2000, null=True)
station_5 = models.CharField(max_length=2000, null=True)
station_6 = models.CharField(max_length=2000, null=True)
station_7 = models.CharField(max_length=2000, null=True)
station_8 = models.CharField(max_length=2000, null=True)
station_9 = models.CharField(max_length=2000, null=True)
station_10 = models.CharField(max_length=2000, null=True)
station_11 = models.CharField(max_length=2000, null=True)
station_12 = models.CharField(max_length=2000, null=True)
station_13 = models.CharField(max_length=2000, null=True)
station_14 = models.CharField(max_length=2000, null=True)
station_15 = models.CharField(max_length=2000, null=True)
station_16 = models.CharField(max_length=2000, null=True)
station_17 = models.CharField(max_length=2000, null=True)
station_18 = models.CharField(max_length=2000, null=True)
station_19 = models.CharField(max_length=2000, null=True)
station_21 = models.CharField(max_length=2000, null=True)
station_22 = models.CharField(max_length=2000, null=True)
station_23 = models.CharField(max_length=2000, null=True)
station_24 = models.CharField(max_length=2000, null=True)
station_25 = models.CharField(max_length=2000, null=True)
station_26 = models.CharField(max_length=2000, null=True)
station_27 = models.CharField(max_length=2000, null=True)
station_28 = models.CharField(max_length=2000, null=True)
station_29 = models.CharField(max_length=2000, null=True)
station_30 = models.CharField(max_length=2000, null=True)
使用ajax请求逐个添加数据。
所以我必须从
station_1
…检查是否没有,添加..如果没有..去下一个吧。
以下是我尝试的方法:
def adding_inline_stations(request):
in_line_station = request.GET.get('inLine_stations', None)
obj = TempLine.objects.filter()[0]
for f in obj._meta.get_fields[3:]:
if f is None:
f = in_line_station
f.save()
else:
pass
返回错误的
TypeError: 'method' object is not subscriptable
