Question

I have the following code:

def create
    @user = User.new(params[:user])
    simp_ = User.new(params[:user])
    if @user.gender.blank?
       load './bayes.rb'
       b_obj= Bayes.new
       simp_.gender = b_obj.predict(@user.height, @user.weight)
       predict_(simp_)
    else
      if @user.save
        redirect_to @user
      else
        @title = "Train"
        render 'new'
      end
    end
  end
 ...

  def predict_(_user)
    @user = _user
    render 'predicted' ( I am printing @user.gender here)
  end

Everything works fine and I am able to use user defined class bayes as well. The problem is that the value stored in ‘simp_.gender’ always remain the same, no matter what my function returns. This is causing a lot of problems.

How should I handle this?

Answer 1

First double-check the value returned by b_obj.predict:

gender = b_obj.predict(@user.height, @user.weight)
logger.info "GENDER: #{gender}"
simp_.gender = gender

Try it, then look at the log. If you still need help, edit your question and add information on what was written to the log.
