activerecord-attr-stripper

A ActiveRecord plugin which removes leading and trailing whitespace(include zenkaku space) of attributes before validation.

Installation

Add this line to your application's Gemfile:

    gem 'activerecord-attr-stripper'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install activerecord-attr-stripper

Usage

class Post < ActiveRecord::Base
  include ActiveRecord::Attr::Stripper

  strip_attrs :title, :description, blank_to_nil: true
end

post = Post.new(title: ' 　this is title 　', description: '　')
post.valid?
puts post.title       #=> 'this is title'
puts post.description #=> nil

blank_to_nil option is true, attribute's value returns nil if the attribute is '' after removing leading and tailing whitespace.
