Can't migrate psql database after scaffold - Cloud9

Question

I am getting an "wrong number of arguments (given 1, expected 0)" error when trying to run rake db:migrate on my psql database. This asker had the same trouble, but locking my Gemfile "to gem 'arel', '6.0.0.beta2'" and using rails version 4.2.0.beta4 hasn't fixed the issue though I am able to bundle and am absolutely using these versions. Any help would be much appreciated!

Here is the full trace

rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate

Here is the file 20161104230329_create_mytable.rb

class CreateTables < ActiveRecord::Migration
  def change
    create_table :mytable do |t|
      t.name :string
      t.param1 :integer
      t.param2 :integer
      t.param3 :integer

      t.timestamps null: false

  end
end

Answer 1

You have the order of the field/field type options of your migration reversed. Should be

class CreateTables < ActiveRecord::Migration
  def change
    create_table :mytable do |t|
      t.string :name
      t.integer :param1

      t.timestamps
    end
  end
end
