Adds easy to use identifier creation mechanism.

Add this line to your application's Gemfile:

gem 'identify_it'

And then execute:

$ bundle

Or install it yourself as:

$ gem install identify_it

Add migration to your project

class YourModelName < ActiveRecord::Migration
  def up
    add_column :your_model_name, :string
  end

  def down
    remove_column :your_model_name, :string
  end
end

Just add to your ActiveRecord model a DSL instuction:

has_identifier(format, options)

format - string
options - hash of symbols

With format you are defining how identifier will look like. Main syntax is that a curly brackets you are defining how long each literal would be.

{4}:{5} -> ABCD:ABCDE

In options you can specify:

1. alphabet (:letters, :numbers, :mix)
2. case (:upper, :lower, :mix)

##Examples

has_identifier('AA:{2}-{4}', alphabet: :numbers)
> 'AA:34-1324'
has_identifier('{3}:{3}', alphabet: :mix, case: :upper)
> 'A22:8BS'
has_identifier('{8}', alphabet: :mix, case: :mix)
> '1s5DFG67'
