Using fixtures inside migrations



I want to add data from a fixture file to a table inside a migration.
I’ve saved the file in db/migrate/fixtures/countries.yml

I guess I could just open the file, read the entries, and add them to
the database using AR, but I’m hoping I can use Rails for all that.

Also, if I have a file, say, with 200,000+ records, what would be the
best method (performance-wise) to go about this? I was thinking
splitting the data on multiple files, each about 10,000 records or
so… what do you think?

I don’t want to use SQL for this, to avoid problems between different

Thanks a lot!

I found this:

Do you think it would be better to use rake tasks for this? Or is the
migration better?
