WhereUnlessBlank

The behavior of "where" when querrying for a null value is include the statment and return rows with null value.

This gem creates a simple way to remove statements with null/blank values from query.

Very usefull for search forms avoiding you to worry about unfilled fields.

Add this line to your application's Gemfile:

gem 'where_unless_blank'

And then execute:

$ bundle

Or install it yourself as:

$ gem install where_unless_blank

After install this gem three new methods will be available on ActiveRecord::Base instances. where_unless_blank, ilike_unless_blank and like_unless_blank.

Person.where_unless_blank(age: params[:age]).ilike_unless_blank(name: params[:name])
Person.ilike_unless_blank(name: params[:name], surname: params[:surname])
Person.like_unless_blank(name: params[:name], surname: params[:surname])

If u like short names u can use:

wub or where_ub for where_unless_blank

iub or ilike_ub for ilike_unless_blank

lub or like_ub for like_unless_blank

If all params are blank it will behaivor like all method.
