I did the same thing, I wanted to change a field name and instead of this:

class CreateComments < ActiveRecord::Migration
  def change
    create_table :comments do |t|
      t.string :commenter
      t.text :body

      # this line adds an integer column called `article_id`.
      t.references :article, index: true

      t.timestamps
    end
  end
end

I changed

  t.text :body

to

t.text :comment_body

I tried doing rake

db:migrate

nothing happened as in it went to the command prompt again without any output..., i looked at stack overflow and this guided me to do rake

db:migrate:redo

with out put

-- drop_table(:comments)
   -> 0.0000s
== 20141129044056 CreateComments: reverted (0.0886s) ==========================

== 20141129044056 CreateComments: migrating ===================================
-- create_table(:comments)
   -> 0.0040s
== 20141129044056 CreateComments: migrated (0.0040s) ==========================

and then I loaded my page/controller with commenter_body instead of body and it loaded perfectly.

I think this is also a solution to the same. I dont know if there is any issue in the underneath workings in the model/DB( i am still very new to RoR,my third day actually...)
