修改django中的querydict

修改django中的querydict

在正常的请求/响应周期中访问时，request.POST和request.GET上的QueryDicts将是不可变的.要得到可变版本，您须要使用QueryDict.copy（）.或者,使用一个小技巧

# data == request.GET or request.POST
_mutable = data._mutable

# set to mutable
data._mutable = True

# сhange the values you want
data['param_name'] = 'new value'

# set mutable flag back
data._mutable = _mutable
