I\'m looking to generate a migration file from the schema.rb. is it possible?
I have many migration files at the moment and would like to combine everything into one ma
There's no need to do this. For new installations you should be running rake db:schema:load
, not rake db:migrate
, this will load the schema into the database, which is faster than running all the migrations.
You should never delete migrations, and certainly not combine them. As for accidentally deleting one, you should be using a version control system, such as Git.
