Ruby on Rails gem for generating a unique, random token in an ActiveRecord model.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install uniqable
First include Uniqable concern to your model and then describe columns which you want to propose with uniq token.
class User < ActiveRecord::Base include Uniqable uniqable :uid, :another_column, :or_another_uid_column end
It generates unique and random token before each Model instance is created.
if you want you can use
:to_param option to generate automatically
uniqable :uid, :slug, to_param: :uid
anyway you have one more method
.find_uniqable which one you can use to find your model record
MyModel.find_uniqable params[:uid] # or MyModel.find_uniqable! params[:uid] # this will raise exception ActiveRecord::RecordNotFound if record is absent # or you can use numerical ID same time and Uniqable will detect it and tries to find by primary key (as regular id) MyModel.find_uniqable params[:id] # or MyModel.find_uniqable! params[:id]
and another one is
You can also create your own token callback method and set the field:
class MyModel ... def uniqable_uid(field) self[field] = 100_000 + rand(999_999) end end
