update_attributes not inserting all attributes

I'm trying to use update_attributes and accepts_nested_attributes_for to update some children objects (days_events) from the parents (location) controller.

Everything looks good in params hash but when I attempt to use assign_attributes or update_attributes the actual dates don't get updated.The first days_event record is created in the database successfully as it should with the event_id and location_id but the start_date and end_date fields are empty.

There aren't any model restrictions on the date fields either.

Here's the code in my location(parent) controller:

def update
    logger.debug('PARAMS HASH********'+params.to_s)

    @total_forms=params[:total_forms].to_i
    @current_form=params[:current_form].to_i

    @location = Location.find(params[:id])       

    @location.update_attributes(params[:location])
  end

Here's my params hash:

{
"utf8"=>"Γ£ô", 
"_method"=>"put", 
"authenticity_token"=>"Mz2GzRmqxrygy01d2LdkE6ZZY+fJK1PSlVhFKlVUme8=", 
"location"=>{
    days_events_attributes"
=>{
    "0"=>{
        "start_date"=>"03/14/2013", 
        "end_date"=>"03/14/2013", 
        "_destroy"=>"false", 
        "event_id"=>"588"
        }, "
    1"=>{"
        start_date"=>"", 
        "end_date"=>"", 
        "_destroy"=>"1",
        "event_id"=>"588"
        },
    "2"=>{
        "start_date"=>"",
        "end_date"=>"", 
        "_destroy"=>"1", 
        "event_id"=>"588"
        }
    }
 }, 
 "total_forms"=>"2", 
 "current_form"=>"0", 
 "commit"=>"Add Date s for Next Location", 
 "action"=>"update", 
 "controller"=>"locations", 
 "id"=>"871"
}

Check the date format, MySQL for example uses the YYYY-MM-DD format, if you input an invalid format it will just reject it.

If you want to normalize the date format regardless of what you get as input, I would suggest adding a before_validation hook to your model and do it there. Check the answer on this question for a suggestion, it doesn't deal with dates (it shows how to format a price attribute) but it should give you an idea of what you need to do.

Should you need help formatting the date drop a comment here and I'll get to it as soon as I can.

Hope it helps :)
