我如何改变卡纳克人阵中我一个数据库表的图象? 新的图表将包括新的栏目,这些栏目将列入我的表格,并列入一些栏目。 我试图利用它这样做。
cake schema update <mytable>
但我总是有这一错误:
Warning: <span style="color:Red;text-align:left"><b>SQL Error:</b> 1060: Duplicate column name contact_id </span> in C:wampwww estscakelibsmodeldatasourcesdbo_source.php on line 684
任何帮助?
您不敢说,你正在使用哪一个数据库,假定它符合MySQL。
当我想改变一个表格(加列或删除栏目)时,我确实使用
如果CakePHP似乎不相信表格已改为<代码>app/tmp/cache,删除其中3个子组的内容(但不是这些子组本身有时会造成问题)。
显然,如果你的法典中提到已经不复存在的栏目,你就必须加以编辑。 否则,一切都只能奏效。
