Why am I getting this empty hash?

  • 772

I am using Devise, when submitting the data from the form (user registration), I inspect the parameters in the controller with

 render plain: params.inspect

and I get the following as a result:

<ActionController::Parameters {"utf8"=>"✓", "authenticity_token"=>"H2rNXQCfedwIKrKNtaNQlTGU+EyENNKvR57qYz5qzpggiu4xd3TE4QCdEsPYcq97mEe0FLcBHwhNQQvT15hlzw==", "user"=>{"nombre"=>"test5", "apellido"=>"", "cargo"=>"", "telefono"=>"", "email"=>"[email protected]", "direccion"=>"", "contrato"=>"123", "compania"=>"", "password"=>"123123", "password_confirmation"=>"123123", "user_type"=>"Cliente"}, "commit"=>"Guardar", "controller"=>"registrations", "action"=>"create"} permitted: false>

Now if I want to access the contract, doing the following

 render plain: params[:contrato].inspect

I get a beautiful:

nil

Does anyone know what the heck is going on here?

    In your parameter information:

    {"utf8"=>"✓",
 "authenticity_token"=>
  "H2rNXQCfedwIKrKNtaNQlTGU+EyENNKvR57qYz5qzpggiu4xd3TE4QCdEsPYcq97mEe0FLcBHwhNQQvT15hlzw==",
 "user"=>
  {"nombre"=>"test5",
   "apellido"=>"",
   "cargo"=>"",
   "telefono"=>"",
   "email"=>"[email protected]",
   "direccion"=>"",
   "contrato"=>"123",
   "compania"=>"",
   "password"=>"123123",
   "password_confirmation"=>"123123",
   "user_type"=>"Cliente"},
 "commit"=>"Guardar",
 "controller"=>"registrations",
 "action"=>"create"}

    contratois nested inside user, so the correct way to access it would be with params[:user][:contrato].
