How not to create a new table each time when deploying on heroku?

Question

Ruby on Rails

Hello. Let's say I added a new column to the table, deployed it to heroku, you need to do heroku run rake db:migrate. And, as I understand it, it does not add a column (as on a local server), but re-creates the entire table already with changes, which is extremely inconvenient when testing. There is a solution?

Answer 1

Didn't understand the problem.
db:migrateworks the same on heroku and on your computer, it does not erase the entire data base, as db:resetif you are talking about it. There shouldn't be any problems with testing.

Answer 2

I suspect that during the deployment, uploaded files or photos are falling))) If yes, then this is not a problem in the database) This is your public folder being overwritten.
