rails - how to show and save a date in us format?

I can get my content_date to show in mm/dd/yyyy format and I can save it correctly. If I have a validation error in other data the form redisplays the date the desired way which is mm/dd/yyyy I can also edit a record and see the date in format mm/dd/yy

The problem I have is that editing the record flips the month and year so that

08/02/2012

becomes

02/08/2012

and

08/19/2012

doesn't work at all.

Ironically If I record the record twice in a row and the day is not more than 12 it flips back to the original value

View:

= f.text_field :content_date, id: 'datepicker', size: 10

I got new and create to work with (links controller)

def new
  @link = Link.new
  @link.content_date=Time.new().strftime("%m/%d/%Y")
  ...

def edit
  @link = Link.find(params[:id])
  @link.content_date=Time.new().strftime("%m/%d/%Y") if @link.content_date.nil?

def create
  @link = Link.new(link_params)

  if @link.content_date.nil?
    @link.content_date = Time.new().strftime("%Y/%m/%d")
  else
    @link.content_date = @link.content_date.strftime("%Y/%m/%d")
  end

but update (rails 4.0.2) is now just 

def update
  redirect_to Link.find(params[:id]).tap { |link|
    link.update!(link_params)
  }
end

and I can't figure out how to change the :content_date in the update the way I did in the create

fyi I have the american_date gem in my Gemfile but it doesn't help (and doesn't help if I remove it either).

I don't currently have any date initializer in config/initializers/

js date picker:

$ cat app/assets/javascripts/date-picker.js 

$(function() {
$( "#datepicker" ).datepicker();
});
$(function(){
var dateInput = $("#datepicker");
var format = 'yy-mm-dd';
dateInput.datepicker({dateFormat: format});
dateInput.datepicker('setDate', $.datepicker.parseDate(format, dateInput.val()));
});

I changed

/app/assets/javascripts/datepicker.js

changing

var format = 'yy-mm-dd';

to

var format = 'mm/dd/yyyy';

Then I added a file config/inititlaizers/date-format.js, with

# Date
# ----------------------------
Date::DATE_FORMATS[:default] = "%m/%d/%Y"

# DateTime
# ----------------------------
DateTime::DATE_FORMATS[:default] = "%m/%d/%Y"

# Time
# ----------------------------
Time::DATE_FORMATS[:default] = "%m/%d/%Y %H:%M:%S"

This helped in all the displays and input fields and date-picker but the date still flipped.

Finally (this bit fixes the date flipping part), I changed my controller to be:

def update

  r = Link.find(params[:id])
  r.tap { |link|
    link.update!(link_params)
  } 
  r.update!(:content_date => link_params[:content_date].to_date.strftime("%Y-%d-%m"))
  redirect_to r

  end
