Have a rollback feature

[engahmeds3ed]

Hey,

I was thinking about this matter from some time and wanted to share my thoughts with you here so we can discuss and reach the best solution that we may collaborate together to get it out in awesome way to all users.

Current Behavior

We have upgrades property in the table class and to make rollback, we need to add new item in this array to make query(s) to revert what was done on the previous ones and also change the table version number.

Proposed Behavior

What if we changed the table version to older version and in the code we check if the version in the code is less than the version in the database so we need to call the methods in the upgrades property but pass "down" to it otherwise pass "up" so in the migration method code we can run a query with upgrade and run another query on revert.

What do u think?

Yes, I think you are correct.

• Direction (up|down)
• Depth (how out of date|how far back to go)
• Plan (what methods to call to get from A-E or E-A)
• Realtime validation (does the structure of the table match what is expected for the version)
