Migrations silently fail when passed invalid field [data] type

I just ran into the same issue. I had a typo in my migration, and thus the field wasn't created. I scratched my head for a while, wondering why my database didn't have the field, yet it was in my migration file!

Here's the full migration (it was a HMT model):
class CreateEmployeeSoftwares < ActiveRecord::Migration
  def self.up
    create_table :employee_softwares do |t|
      t.integer       :software_id
      t.intger        :employee_id
      t.timestamps
    end
  end

  def self.down
    drop_table :employee_softwares
  end
end

Notice I had t. "intger", I was missing an "e". At no point did the migration fail or warn me that "intger" isn't a valid data type.

This issue has been automatically marked as stale because it has not been commented on for at least three months.
