Heroku pulls a duplicate column error in a rake db:migrate

After pushing my master branch to heroku from git, I'm now trying to migrate my db file to heroku also but I came across this error

clydiscope$ heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.6472
Migrating to DeviseCreateUsers (20141203201816)
== 20141203201816 DeviseCreateUsers: migrating ================================

-- add_column(:users, :name, :string)
PG::DuplicateColumn: ERROR:  column "name" of relation "users" already exists

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

: ALTER TABLE "users" ADD COLUMN "name" character 

/app/db/migrate/20141206140057_add_name_to_users.rb:3:in `up'

Apparently, there's a duplicate column that I wasn't aware of... I was continuously migrating in the development phase and it seemed to work up to this point. How can I change ,my db now so that heroku accepts it?

Here's the code from the last line.

 class AddNameToUsers < ActiveRecord::Migration
 def up
    add_column :users, :name, :string
 end

def down
  remove_column :users, :name
end
end

Probably just deleting the migration file 20141206140057_add_name_to_users.rb will solve the problem (of course, after committing and push to Heroku).
