    Metadata details:
    filename: registrations_controller.rb
    path of file: ./repos/i-diario/app/controllers
    
    the code of the file until where you have to start completion: class RegistrationsController < ApplicationController

  def new
    @signup = Signup.new(params[:signup])
  end

  def create
    Rails.logger.info(
      "LOG: RegistrationsController#create: #{params[:signup].except(:password, :password_confirmation).to_json}"
    ) if params[:signup]

    @signup = Signup.new(params[:signup].to_unsafe_h)
    password = params[:signup][:password]

    if weak_password?(password)
      flash.now[:error] = t('errors.general.weak_password')
      render :new
    elsif @user = @signup.save
      if @user.active?
        flash[:notice] = I18n.t('devise.registrations.signed_up')
        sign_in_and_redirect @user
      else
        respond_with @signup, location: new_user_session_path, notice: I18n.t('registrations.students')
