代码生成器说明

代码生成器—不支持功能说明

Online表单属于低代码在线开发概念，在线js增强、sql增强、自定义按钮、等一些高级组件不支持代码生成，请了解。

不支持清单

• 不支持默认值表达式的生成
• JTreeSelect树形下拉框 编辑操作时无法赋值issues/I1R1RC
• 代码生成器生成自定义树，下载代码时树失效问题 #2271
• 自定义按钮 #1525
• 表单自动生成不会生成field_href字段 #1435
• 请问一下，online表单中的 js增强，java增强，自定义按钮之类的功能，如果生成代码，是不是就全部失效了 #2021
• 控件默认值显示不正确，#{sysUserName}，没有做转换 #2214
• 生成代码后和online表单开发中展现的不一样 #2411
• Online表单开发，mysql中bigint类型导入表单类型对应Integer,插入数据时超过长度限制 #3029
• Jeecg Boot 2.2 【dadf6a7】版本，生成代码后控件失效，变【文本框】 #1363
• 在线表单开发中功能测试代码与代码生成的代码功能不一致 （select二级联动） #1302
• online表单开发 联动组件怎么设置查询  #1456
• 子表使用了省市区组件，不能正常显示
• 代码生成下载到本地功能无法使用 #3039
• 主键策略如何切换生成
• 代码生成器无法用自定id作为主键策略 #1033
• online表单配置数据库表字段类型问题 #1483
• 在线生成表单 主键策略想设置成自增，但是修改后还是插入的很长的ID 从而报错issues/I3CPK8
• online表单拓展参数 #4787

已支持清单

• 使用代码生成器时,如果项目目录(文件夹路径)存在特殊符号时, 会被转义,导致读取文件时提示无法找到文件. #2567
• 建议代码生成，列表加上图片预览功能，我们框架已经内置预览， #3022
• 生成的代码无法上传/下载 图片或文件（阿里oss）

生成代码功能的代码在哪个分支？还是这部分没有开源呢

生成代码功能的代码在哪个分支？还是这部分没有开源呢

人家靠这吃饭呢，怎么可能开源

[lengfaqiang]

这类的问题是怎么回事的呢？当前读取下替换问题
freemarker.core.InvalidReferenceException: The following has evaluated to null or missing:
==> po.isShowList [in template "default\one\java\${bussiPackage}\${entityPackage}\vue3\${entityName}__data.tsi" at line 10, column 9]

---

Tip: It's the step after the last dot that caused this error, not those before it.

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
