No Method Error on Sinatra

After setting up my config.ru and gemfile, my post no longer wants to work.

First, I have to have my DataMapper.setup in my main.rb and I cannot run any DataMapper methods in my irb.

Second, whenever I submit a form via POST for some data to be saved to my db Sinatra returns with...

NoMethodError at /
undefined method `each' for "asdfasdf":String

file: resource.rb
location: attributes=
line: 329

main.rb

#Required Gems
  require 'sinatra'
  require 'data_mapper'

DataMapper.setup(:default, ENV['DATABASE_URL'] || 'postgres://host:password!@localhost
/blog_development')


#Database Migration
  class Code
    include DataMapper::Resource
    property :id,           Serial
    property :code,         String, :required => true
    property :translation,  String
    property :completed_at, DateTime
  end

#Set up Migration
  DataMapper.finalize

#Routes Section
get '/' do
  @codes = Code.all
  slim :index
end

#Get Code
get '/:code' do
  @morse_code = params[:code]
  slim :code
end

#POST Code
post '/' do
  @code = Code.create params[:code]
  redirect to('/')
end

Gemfile

source :rubygems

gem "sinatra", "~> 1.3.3"

gem "data_mapper", "~> 1.2.0"

gem "slim", "~> 1.3.4"

gem "dm-postgres-adapter", "~> 1.2.0"

config.ru

require 'bundler'

Bundler.require

require './main'

DataMapper.setup(:default, ENV['DATABASE_URL'] || 'postgres://host:password@localhost

/blog_development')

run Sinatra::Application

Note that asdfasdf is the text I put in the input box for the form before submit.

For the repo in case anyone wants to live test it... https://github.com/thejourneydude/morsecode

You are calling Code.create params[:code]. Try Code.create :code => params[:code]. This way the string does not end up where datamapper expects an attribute hash.
