And solving that problem isn't simple (at least, not that I know. I'm going to use the same scenario from my blog post yesterday.I'm not talking about the invalid record problem anymore, only the problem with an update undoing changes from another update. I added a lock_version column, so Rails will automatically do optimistic locking.element here, this can no longer be used for input in the web interface.
You probably made a wrong design decision here, so get back to the drawing board and rethink this part of your application if you can.This includes both code snippets embedded in the card text and code that is included as a file attachment.Excepted from this license are code snippets that are explicitely marked as citations from another source. Adding callbacks to disable them later is nasty and will result in code that’s more difficult to maintain.If you can’t or you’re completely sure you have a valid reason to skip your callbacks, you probably tried something like removing the callback method but found out that didn’t work anymore.
