Python Django formwizard和ModelFormSet保存

我正在重写我们应用程序的一大块，它要求用户创建一个

项目

，并附带

奖励

表单分为不同的步骤，前两个步骤是正常的

项目

，下一个步骤是

奖励

，最后是一个简单的预览，让用户来回切换以创建一个完美的

项目

for rw in form_list[2].save(commit=False):
    rw.project = project
    rw.save()

渲染重定向时，它显示所有数据都已清理，这意味着表单有效，并且所有项目数据都保存到project

我可以看到奖励数据不会保存，因为它没有被调用，但我迄今为止尝试的每个解决方案都失败了

如何在保存时在此解决方案中实施奖励？

也许有人可以解释一下，非常感谢

这样行吗？假设

奖励

有

项目

for rw in form_list[2].save(commit=False):
    rw.project = project
    rw.save()

@Rohan在中编辑了这个问题，在解决方案最终奏效时，我对整个过程进行了过度思考：(
