Deployment of Rails 4 App to Heroku generates error

My Rails 4 application works perfectly on my local machine, but when I deploy to Heroku I get an application error. The error occurs even though Heroku says the deployment was successful. The text of the error message is: 

An error occurred in the application and your page could not be served.   Please try again in a few moments.
If you are the application owner, check your logs for details.

To troubleshoot the problem, I ran "heroku logs" in the console, which generated the following:

I'm not certain, but I think I've identified the source of the problem. The following line stands out to me:

2015-06-18T00:43:16.824808+00:00 app[web.1]: /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.1.8/lib/active_support/dependencies.rb:247:in `require': /app/app/helpers/simple_form.rb:5: syntax error, unexpected ')', expecting => (SyntaxError)

Here's the contents of my simple_form helper file:

module SimpleForm
  module Inputs
    class DateTimePickerInput < Base
      def input
        @builder.text_field(attribute_name, :class => 'date_time_picker', input_html_options)
      end    
    end
  end
end

Note that before I coded the helper file, I could successfully deploy the application to Heroku. It appears Heroku is balking at my syntax - particularly, the closing parenthesis). However, I don't know how to correct the issue. What do I need to do to satisfy Heroku? I'd appreciate any help in getting my application successfully deployed again. Thanks!

Just replace:

@builder.text_field(attribute_name, :class => 'date_time_picker', input_html_options)

With:

@builder.text_field(attribute_name, input_html_options.merge(:class => 'date_time_picker'))

And it will do the trick.

Edit After reading again this answer I realize that this code always overwrite the :class parameter. If you want use the called parameter instead of the default parameter, you can achieve this changing merge with reverse_merge.

Edit2 You can remove the curly braces of a hash option parameter only if it is the last parameter. For this case, text_fields accepts 2 parameters and :class belongs to the second.
