类型错误：无法将序列乘以类型为"unicode"的非整数

Question

@api.ochange('长度'，'宽度'(

def_compute_size_id(self(:

for s in self:
if (s.length and s.width):
s.size_wise = s.length * s.width

Answer 1

您应该将变量强制转换为类型int:

@api.onchange('length','width')
def _compute_size_id(self):
for s in self:
if (s.length and s.width):
s.size_wise = int(s.length )* int(s.width)
