在反应锅炉板项目之后,我想使用react-redux-forms并查看'get started'指南,它说只使用combineForms。我试图解决这个问题好几个小时,文档没有多大帮助。希望有人能够告诉我这里发生的事情。
我的研究时间让我相信:
以下是我的文件:

从react-boiler-plate克隆后,大部分代码几乎都没有被触及,只是将index.js更改为只有表格并修改了reducer.js。
我可以从redux dev工具中看到我有表单键:
但是我收到的错误消息是该应用无法加载:
提前感谢一百万!
答案 0 :(得分:0)
终于弄明白了。因为我使用的是immutableJS,所以我只需要改变导入:
import { Form, Control } from 'react-redux-form';
为:
import { Form, Control } from 'react-redux-form/immutable';
