Fixing an error with Datepicker and using Rack Protection EscapedParams with Jump Start Sinatra project

[workalicious]

I’ve been going through the Jump Start Sinatra book and nearing the end.

I’m checking out Rack::Protection::EscapedParams but when I try to update with jQuery’s Datepicker I get an ArgumentError - invalid date: 500 Internal Server Error. Any ideas or why this error occurs?

This is what my date looks like:

class Song
  ... 
    def released_on=date
      super Date.strptime(date, '%m/%d/%Y')
    end
end

Thanks!

I believe I’ve found the answer to my problem. I think it has to do with the original format with the forward slash and how Rack::Protection::EscapedPams handles those. I fixed my problem by explicitly setting the date format coming from the Datepicker object. The default Datepicker format is “02/08/2015”

Adding dateFormat solved the problem:

# application.coffee (excerpt)
$('#released_on').datepicker( dateFormat: "yy-mm-dd", changeYear: true, yearRange: '1940:2000' )

and

# song.rb (excerpt)
def released_on=date
  super Date.strptime(date)
end

It seems like if I wanted to use dateFormat: "mm-dd-yy" in Datepicker() then super Date.strptime(date, '%m-%d-%Y') works too.
