I found a way to do it. To convert the multi-parameter attributes that are submitted in the form to a specific time zone, add a method in your controller to manually convert the params into a datetime object. I chose to add this to the controller because I did not want to affect the model behavior. You should still be able to set a date on the model and assume your date was set correctly.
-- def create convert_datetimes_to_pdt("start_date") convert_datetimes_to_pdt("end_date") @model = MyModel.new(params[:my_model]) # ... end def update convert_datetimes_to_pdt("start_date") convert_datetimes_to_pdt("end_date") # ... end def convert_datetimes_to_pdt(field) datetime = (1..5).collect {|num| params['my_model'].delete "#{field}(#{num}i)" } if datetime[0] and datetime[1] and datetime[2] # only if a date has been set params['my_model'][field] = Time.find_zone!("Pacific Time (US & Canada)").local(*datetime.map(&:to_i)) end endNow the datetime will be adjusted to the correct time zone. However, when the user goes to edit the time, the form fields will still display the time in UTC. To fix this, we can wrap the fields in a call toTime.use_zone:
Time.use_zone("Pacific Time (US & Canada)") do f.datetime_select :start_date endYou received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
