Zend Framework:此行已标记为只读 [英] Zend Framework: This row has been marked read-only

问题描述

这是我第一次遇到这个问题.保存我的模型之一时，我收到错误消息:此行已标记为只读".不知道为什么我会收到这个错误以及如何解决它.堆栈跟踪对我没有帮助.如何解决此问题以便保存记录?

This is the first time I've come across this issue. When saving one of my models I get the error message: "This row has been marked read-only". Not sure why I'm getting this error and how to solve it. The stack trace didn't help me. How can I resolve this issue so I can save the record?

推荐答案

将一行标记为只读可能是以下任一操作的结果:

Having a row marked as read only can be the result from any of the following operations:

• 与另一个表连接的 Zend_Db_Select 查询
• setIntegrityCheck(false) 已在选择对象上设置
• 一列或多列是计算表达式的结果

• The Zend_Db_Select query joined with another table
• setIntegrityCheck(false) was set on the select object
• One or more columns is the result of an evaluated expression

如果上述任何一个条件为真，那么结果行对象将被标记为只读，因为 Zend_Db 不能保证结果中的所有列都引用了选择对象的原始父表.因此，对行对象调用 update()、save() 或 delete() 的任何尝试都将失败.

If any of the above conditions are true, then the resulting row object will be marked as read only, because Zend_Db cannot guarantee that all columns in the result reference the original parent table of the select object. Therefore any attempt to call update(), save(), or delete(), on the row object will fail.

其中一些信息散布在 Zend_Db_Table 参考，如果您搜索 integrity，您可以看到许多行将被标记为只读的实例.

Some of this information is spread throughout the Zend_Db_Table reference, where if you search for integrity you can see a number of instances where rows will be marked read only.
