Rails 4.1.9

[georgediaz88]

Hello,

We're trying to upgrade our application to latest Rails version of the 4.1 series and it appears running data migrations is now storing in the wrong table. (i.e. in 'schema_migrations' and not 'data_migrations'). Is there a fix our there or is this a known problem?

Any help would be great.

Thanks!

any update on this?

@georgediaz88 looks like rails 4.0 made updates to migration process and introduced http://apidock.com/rails/ActiveRecord/SchemaMigration which conflicts with data-migrate code. What do you think if I create a new version data-migrate that has a dependency on rails 4.0 and up. This version will not be backward compatible though, so data-migrate "1.2.0" will not be maintained.

@ilyakatz, this sounds like a reasonable compromise for those of us who'd like to continue using this gem. Thanks.

Ok, cool. I have a working solution in #27, just need to clean it up and create separate branches for the versions, so will try to do this in the coming week

@ilyakatz, that sounds great to me. I'd like to continue using this gem as well. Let me know if you need a hand as well. Thanks.

@georgediaz88 thanks. if you could try it out with that new branch, that would be great. just put this in your gemfile

gem "data_migrate", github: "execonline-inc/data-migrate", 
  branch: "fix_data_migration_table"

@ilyakatz, just tried your branch and it worked! I was able to add a new data migration, run the data migrate command, and see it in the data_migrations table. So, this worked for me. I'm glad to see this being worked on.

[ilyakatz]

ok, thanks for checking. I want to do a bit more testing to make sure that this doesn't rerun all those data migrations that are recorded in schema_migrations as this could be pretty disastrous. Feel free to poke me again if i don't get it out next week.

[georgediaz88]

yea, totally. Sounds good!
