How use validation inclusion in rails - 


class stadium < activerecord::base validates :name, :presence => true validates :city, :presence => true validates :contructiondate, :presence => true validates :capacity, :presence => true validates :image, :presence => true  validates :name, :uniqueness => true validates :city, :uniqueness => true validates :capacity, :numericality => { :only_integer => true, :greater_than_or_equal_to => 0 } validates :image, :format => { :with => /^(http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?$/ix, :message => "uniforme invalido", :multiline => true } validates :city, :inclusion => { :in => %w(belo horizonte brasilia curitiba fortaleza manaus natal recife rio de janeiro salvador sao paulo),  :message => "%{value} no esta permitido" }  validate :mydate_is_date?  def mydate_is_date?     errors.add(:contructiondate, 'must valid date') if !contructiondate.is_a?(date)  end end

i have problem inclusion, works words natal, manaus, salvador, words "sao paulo", "rio de janeiro" not work, how fix it?

thanks

try escaping spaces backslash \.

without escaping:

> %w(belo horizonte brasilia curitiba fortaleza manaus natal recife rio de janeiro salvador sao paulo) => ["belo",  "horizonte",  "brasilia",  "curitiba",  "fortaleza",  "manaus",  "natal",  "recife",  "rio",  "de",  "janeiro",  "salvador",  "sao",  "paulo"]

with escaping: 

> %w(belo horizonte brasilia curitiba fortaleza manaus natal recife rio\ de\ janeiro salvador sao\ paulo)                                         => ["belo",  "horizonte",  "brasilia",  "curitiba",  "fortaleza",  "manaus",  "natal",  "recife",  "rio de janeiro",  "salvador",  "sao paulo"]
