Split an attribute into multiple virtual attributes, and use a new FormBuilder method called multi_text_field to allow users to enter a long field in individual pieces. Useful for fields with discrete break points, like social security numbers or phone number.
Say you have a User class with a phone number attribute that you want to split up into area code | three digits | four digits on the user signup form. Add the following to your model:
attr_splitter :phone_number, prefixes: [ :first, :second, :third ]
In your form, replace
f.text_field :phone_number
with
f.multi_text_field :phone_number, fields: { first: 3, second: 3, third: 4 }
The value of each item in the fields hash specifies the max character length allowed for that field.
Add this line to your application's Gemfile:
gem 'attr_splitter'
And then execute:
$ bundle
Or install it yourself as:
$ gem install attr_splitter
