How to declare an array data type in rails generator

Question

I am aware of t.text :tags, array: true, default: [] this syntax in migration to create an array of data type text. Can I do the same in the rails generator itself?

You can do this following as:

rails g scaffold Todo tags:array

And you can check migrate file which was generated:

class CreateTodos < ActiveRecord::Migration
  def change
    create_table :todos do |t|
      t.array :tags

      t.timestamps null: false
    end
  end
end

You can use array itself if you use a supported database like postgresql

rails g resource Todo  tags:array

So this will be an array which can hold anything like ruby array?
