[sql] Rails 4 LIKE query - ActiveRecord adds quotes

While string interpolation will work, as your question specifies rails 4, you could be using Arel for this and keeping your app database agnostic.

def self.search(query, page=1)
  query = "%#{query}%"
  name_match = arel_table[:name].matches(query)
  postal_match = arel_table[:postal_code].matches(query)
  where(name_match.or(postal_match)).page(page).per_page(5)
end
