PG::UndefinedTable: ERROR: table "table-name" does not exist

I was messing with my database, creating and deleting tables. I deleted few migration files after pushing them to heroku. Previously I created a table 'moms'. Later I wanted to rename it, so I deleted 'moms' and created new table 'minutes_of_meetings'. I did $rake db:migrate and everything was done successfully and my app is running perfectly on localhost.

After pushing it to heroku, when I did $heroku run rake db:migrate, it generated the following log:

  ActiveRecord::SchemaMigration Load (0.7ms)  SELECT "schema_migrations".* FROM "schema_migrations"
  Migrating to DropMoms (20150823142852)

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

                                                                                     PG::UndefinedTable: ERROR:  table "moms" does not exist

      /app/vendor/bundle/ruby/2.2.0/gems/activerecord-4.2.0/lib/active_record/connection_adapters/postgresql/database_statements.rb:155:in `block in execute'

I created a new table 'moms' in heroku so that it can be deleted when migration runs. I did this:

$ heroku run Ruby console for rails-app-name >> ActiveRecord::Migration.create_table :moms 

I also created a migration to create table 'moms'. But still the error persists.

EDIT:

This is my CreateMoms migration file:

class CreateMoms < ActiveRecord::Migration
  def change
    create_table :moms do |t|
      t.string :name
      t.timestamp null: false
    end
  end
end

When I run heroku run rake db:migrate:up
