Attribute is not accessible in Class (Sinatra, Twitter)

[Malachai Frazier]

Weirdness with my POST action. I'm trying to create a new user with a successful Twitter connection. But ['data']['screen_name'] isn't letting me access the screen_name directly. Is there a known 'best practice' workaround for this?:

post "/success" do
selfy = HTTParty.get(self_url,{
:query => {:access_token => session[:access_token], :map => true}}).first
User.create selfy['data']['screen_name'] => params[:username], :email => params[:email]
@username = params[:username]
redirect "/:username"

ArgumentError at /success

The attribute 'captcussa' is not accessible in User

It looks to me like what's actually happening there is you're trying to use the screen_name as a column in your User table.  If you schema is something like

User(user_name:String, screen_name:String, email:String)

Then your create command should be

User.create(:user_name => params[:username], :screen_name => selfy['data']['screen_name'], :email => params[:email])

Your current code is trying to do

User.create('captcussa' => params[:username], :email => params[:email])

But there's no 'captcussa' column in your schema, so the ORM hasn't put an accessor on the User object
