How to get selected timezone from dropdown in rails

Drop down for timezones in form

<%= time_zone_select :time_zone, ActiveSupport::TimeZone.all, nil,
 {:include_blank => false,:prompt=>"Select Time Zone"} %>

After selecting some timezone and submitting form, when I do params["time_zone"] I get

"#<ActiveSupport::TimeZone:0x00000001ff5450 @name=%22American Samoa%22, @utc_offset=nil, @tzinfo=#<TZInfo::TimezoneProxy: Pacific/Pago_Pago>, 
 @current_period=#<TZInfo::TimezonePeriod: #<TZInfo::TimezoneTransitionDefinition: #<TZInfo::TimeOrDateTime: 439038000>,#<TZInfo::TimezoneOffset: -39600,0,SST>>,nil>>, 
#<ActiveSupport::TimeZone:0x00000002024bb0 @name=%22International Date Line West%22, @utc_offset=nil, @tzinfo=#<TZInfo::TimezoneProxy: Pacific/Midway>,..............

How I get selected timezone? Note: I save timezone in string

Simply call .name on the ActiveSupport::TimeZone object:

irb(main):055:0> ActiveSupport::TimeZone.new("American Samoa").name
=> "American Samoa"

You can can do this with a custom setter. Example:

class City < ActiveRecord::Base
  # automatically convert ActiveSupport::TimeZone 
  # objects into a serializable string.
  def time_zone=(tz) 
    super(tz.try(:name) || tz)
  end
end

class CitiesController
  def create
    @city = City.create(city_params)
    respond_with(@city)
  end

  def city_params
    params.require(:city).permit(:time_zone)
  end
end

It looks like your time_zone_select is actually called time_zone rather than timezone so try doing params['time_zone'].
