动态表单自定义字段解决方案

1. 背景：

有些项目可能会有要求，客户可以自定义设计字段，并且字段还需要在后台设置可展示、可搜索。

2. 场景：

比如说报名场景，我们并不知道客户想让用户填哪些东西。下面我就举个例子，场景前提介绍：

我有一个平台，动态表单是平台功能，可以独立运行
我有一个比赛系统，比赛系统是平台下的产品，依赖平台生存
我需要在平台上设计一个动态表单功能可以提供给子产品使用

实现大概过程：

在平台创建动态报名表单
比赛系统创建比赛选择创建的报名表单
搜索、展示报名数据

3. 实现步骤

3.1 设计动态表单

使用市面上的开源表单设计器修改一下生成结构，改成我们想要的结构如：

{"form": "apply","form_name": "报名申请表","form_desc": "报名申请表，请各位选手认真填写，填写前请认真阅读报名要求，如不符将会拒绝","start_time": "2023-10-19 09:29:37","end_time": "2023-10-19 09:29:37","create_time":"2023-10-19 09:29:37","pay": true,"pay_price": 100,"pay_desc": "支付描述","system_module": "ims","system_module_router": "","system": "赛事管理系统","theme": "default","cssCustom": "","ruleJsCustom": "","modify": "已提交数据是否可修改，0-不可修改/1-不可修改/3-部分可修改","children_unique": ["uuid"],"children": [{"filed": "contestId","type": "hiddenFiled","value": "00a0ca716cc0487d909b5c8654d1cbc0""column_name": "比赛id","column_desc": "比赛id隐藏字段",},{"id": "","sort": 1,"filed": "name","column_name": "姓名","column_desc": "姓名与身份证上的姓名必须相同","type": "text","require": true,"min": 2,"max": 30,"ruleText": "姓名必须填写，且字符在2-30个范围内"},{"id": "","sort": 2,"filed": "participation_type","column_name": "参加身份","column_desc": "个人/企业","type": "radio","require": true,"default": "1","choose": [{ "label": "个人", "value": "1" },{ "label": "企业", "value": "2" }],"ruleText": "参加身份必须选择"},{"id": "","sort": 3,"filed": "hobby","column_name": "爱好","column_desc": "爱好Tag","type": "checkbox","require": false,"min": 1,"max": 3,"choose": [{ "label": "唱歌", "value": "1" },{ "label": "跳舞", "value": "2" },{ "label": "打球", "value": "2" },{ "label": "滑雪", "value": "2" }],"ruleText": "爱好必须选择1-3个"},{"sort": 4,"filed": "introduce","column_name": "介绍","column_desc": "尽量写一些特长优势","type": "textarea","require": true,"max": 500,"ruleText": "介绍字符在500个范围内"},{"id": "","sort": 5,"filed": "tel","column_name": "电话号码","column_desc": "电话号码，只支持中国地区电话号码","type": "number","require": true,"rule": "tel","ruleText": "电话号码填写错误"},{"id": "","sort": 6,"filed": "birthday","column_name": "生日","column_desc": "出生年月日","type": "year / date / dateTime","require": false,"format": "yyyy-mm-dd"}.......]
}

该结构支持许多自定义设计，如是否需要支付、哪些角色可以提交数据、字段数据查重、提交过的数据是否能修改、常见字段设计、定制化组件等等。这些数据结构存在mysql，这一部分主要是和前端商量怎么样把客户想要设计的表单渲染出来，最终这段json，会渲染成html、js代码，然后返回到前端。

3.2 后端接受表单创建请求

后端在收到创建动态表单请求的时候，需要在mongodb中创建一个集合，一个集合对应着一个表单类型。

3.3 用户填写数据，前端发送用户填写的数据到后台

后端平台收到这个请求，通过表单配置中的system_module区分，转发到子产品中，子产品做一些业务操作、验证等等，验证通过存到mongodb对应集合中，例如

{"_id": "4dc000acd35648c5b273f52b80fa8166","form": "apply","userId": 1001,..."children": [{"filed": "contestId","id": "1","type": "hiddenFiled","label": "比赛Id","value": "00a0ca716cc0487d909b5c8654d1cbc0","searchText": "第十届互联网大赛"},{"filed": "name","filed": "","id": "2","type": "text","label": "姓名","value": "张三","searchText": "张三"},{"filed": "participation_type","id": "3","type": "radio","label": "参加身份","value": "0","ItemText": "个人","searchText": "个人"}]
}
