golang办公流程引擎初体验js-ojus/flow——系列四

1.办公流程概念 

流程大致是这样的：

1.管理员定义好流程类型doctype，这个下面再分流程类型workflow1，workflow2，workflow下再具体分为节点node1，node2，

再定义通用的状态state，通用的动作action，以及根据workflow1下的节点来定义流程走向transition，

再定义contex里的用户-组-角色-权限

2.对于一个要走流程的文件document_001数据表的某个文件，先建立一个document，再给它定义多个事件event，根据workflow1下的节点多少来定义，节点数-1个事件，也就是transition的个数。这个事件就是定义将document_001里的某个文件从状态1 state1改为state2的动作action。

3.开始走流程了，用事件event来修改document_001数据表里某个文件的状态，这个状态从state1变为state2，符合node1里的state1到node2里的state2，也符合transition里的state1——action1——state2

2.测试代码

3.flow自身的测试

安装mysql

建立flow数据库的用户：

CREATE USER 'travis'@'localhost' IDENTIFIED BY '';

在Navicat里新建一个flow数据库，选择utf8mb4——它源码里有个地方交代了。

开始数据库里的表下面是没有内容的，与下图不同。

然后给用户travis赋权。

必须将setup_db.sh文件拷贝到sql文件夹上一级，否则会出现下列错误：

将sql文件里的setup_db.sh和setup_blob_dirs.sh拷贝到上一级目录里（flow文件夹里），然后cmd窗口进入这个文件夹，运行

setup_db.sh -t

setup_blob_dirs.sh

go test

4.mysql和sqlite数据库问题

Flow里的sql语句是mysql的，和sqlite差别很大。从数据表初始化的sh文件开始就不同，一直到flow的go文件里的数据表插入数据，查询数据，jion连接表格，unique多列集合的约束，枚举数据类型，生成view数据表视图等等，太多的不同了。

在sqlite里，新建表用sh文件，也可以用改造好的beego自动建表，
