Unit を County で拡張しようとすると、特にアプリケーションを再起動して ORM を初期化するときに、エラーが発生します。[注: 単一テーブルの継承を試みています]
ORM は私の DB スキーマを管理しています:this.ormsettings.dbcreate=dropcreate
モデル ディレクトリから County.cfc を削除すると、ORM が初期化され、アプリケーションが正常に起動します。County.cfc をモデル ディレクトリに戻すと、エラーが再び発生します。

奇妙なことに、私はすでに別のエンティティで同様のことを行っています (DiscussionPost は Post を拡張しています):
役職：
<cfcomponent persistent="true" entityname="Post" table="Posts" discriminatorColumn="type">
<cfproperty name="id" fieldtype="id" column="post_id" generator="identity">
<cfproperty name="promotions" fieldtype="one-to-many" cfc="PostPromotion" fkcolumn="post_id" singularname="promotion">
<cfproperty name="comments" fieldtype="one-to-many" cfc="PostComment" fkcolumn="post_id" singularname="comment">
<cfproperty name="user" fieldtype="many-to-one" cfc="User" fkcolumn="user_id">
<cfproperty name="text" type="string" sqltype="varchar(1000)">
<cfproperty name="timestamp" type="date" ormtype="timestamp">
</cfcomponent>
ディスカッション投稿:
<cfcomponent persistent="true" entityname="DiscussionPost" table="Posts" extends="Post" discriminatorValue="discussionpost">
<cfproperty name="discussion" fieldtype="many-to-one" cfc="Discussion" fkcolumn="discussion_id">
<cfproperty name="title" type="string" sqltype="varchar(200)">
</cfcomponent>
私は何が欠けていますか？
