渲染时捕获ValueError：需要多于1个值才能解压缩

Question

我试图将生成的“选择”传递给我的模型字段，请问问题出在哪里？

#models.py
...

def quantity_total():
        for x in range(0,100): return "(" + str(x) + "," + str(x) + "),"

QUANTITY = (quantity_total())

class Package(models.Model):
   ...
   ...
   quantity =  models.SmallIntegerField(choices=QUANTITY, max_length=3)

谢谢你们

Answer 1

choices应该是2元组的迭代，而不是字符串。

def quantity_total():
        return ((x, str(x)) for x in xrange(100))
