I use Tim Pope's excellent rails.vim
and its shortcuts. One of the shortcuts I use pretty
regularly is :Emigration or :Emi to edit the last migration.
I usually create the migration from bash, by invoking the usual Rails
commands. After the migration is created, I find it hard to edit
that file, because of the timestamp in the name. That's why
I usually open Vim and then use :Emi to edit that file.
Well, I've decided to write a small bash function to edit that file straight from bash:
emi() {
$EDITOR $(find -E db/migrate -type f | sort | tail -n 1)
}
Place it in your .bashrc or .zshrc and you're good to go.
