Orm 一对多非互惠

我对menu.cfc和menuItem.cfc的多对一/一对多关系有问题。它们都扩展了node.cfc（在末尾声明）

index.cfm

<cfset oMenu = entityNew( "menu" )>
<cfset oMenu.setTitle( "Main menu" )>
<cfset entitySave( oMenu )>
<cfset ORMFlush()>

<cfset oMenuItem = entityNew( "menuItem" )>
<cfset oMenuItem.setTitle( "First main menu item" )>
<cfset oMenuItem.setMenu( oMenu )>
<cfset entitySave( oMenuItem )>
<cfset ORMFlush()>

<cfdump var="#oMenu.getMenuItems()#">
<!--- array[empty] --->
<!--- WHY ?--->

<cfset oMenu = entityNew( "menu" )>
<cfset oMenu.setTitle( "Main menu" )>
<cfset entitySave( oMenu )>
<cfset ORMFlush()>

<cfset oMenuItem = entityNew( "menuItem" )>
<cfset oMenuItem.setTitle( "First main menu item" )>
<cfset oMenuItem.setMenu( oMenu )>
<cfset entitySave( oMenuItem )>
<cfset ORMFlush()>

<cfset oMenu.addMenuItem( oMenuItem )>
<cfset entitySave( oMenu)>
<cfset ORMFlush()>

<cfdump var="#oMenu.getMenuItems()#">

在数据库中，我的菜单项。菜单id是正确的

我也试过了

<cfset oMenu = entityNew( "menu" )>
<cfset oMenu.setTitle( "Main menu" )>
<cfset entitySave( oMenu )>
<cfset ORMFlush()>

<cfset oMenuItem = entityNew( "menuItem" )>
<cfset oMenuItem.setTitle( "First main menu item" )>
<cfset entitySave( oMenuItem )>
<cfset ORMFlush()>

<cfset oMenu.addMenuItem( oMenuItem )>

<cfdump var="#oMenu.getMenuItems()#">
<!--- array[empty] --->

在数据库中，我的menu\u item.menu\u id为空

如果你知道我做错了什么，那就好了。 谢谢

我通过这样做

和

解决了这个问题

它现在似乎起作用了

index.cfm

<cfset oMenu = entityNew( "menu" )>
<cfset oMenu.setTitle( "Main menu" )>
<cfset entitySave( oMenu )>
<cfset ORMFlush()>

<cfset oMenuItem = entityNew( "menuItem" )>
<cfset oMenuItem.setTitle( "First main menu item" )>
<cfset oMenuItem.setMenu( oMenu )>
<cfset entitySave( oMenuItem )>
<cfset ORMFlush()>

<cfdump var="#oMenu.getMenuItems()#">
<!--- array[empty] --->
<!--- WHY ?--->

<cfset oMenu = entityNew( "menu" )>
<cfset oMenu.setTitle( "Main menu" )>
<cfset entitySave( oMenu )>
<cfset ORMFlush()>

<cfset oMenuItem = entityNew( "menuItem" )>
<cfset oMenuItem.setTitle( "First main menu item" )>
<cfset oMenuItem.setMenu( oMenu )>
<cfset entitySave( oMenuItem )>
<cfset ORMFlush()>

<cfset oMenu.addMenuItem( oMenuItem )>
<cfset entitySave( oMenu)>
<cfset ORMFlush()>

<cfdump var="#oMenu.getMenuItems()#">

您是否尝试过

EntityReload（）

从数据库中重新加载实体数据？是的，我在删除创建过程后尝试过

，效果相同。您是否尝试过在没有前两个EntitySave（）和EntityFlush（）的情况下执行此操作？似乎您只需要保存一次。不，我不能，因为oMenu需要有一个ID才能添加到oMenuItem。
