refactor and move controller code into model issues

So I'm running into some issues that I'm not aware of how to solve when I'm improving my code.

Currently in my controller#show I have this ugly piece of code:

def show
  @room = Room.find(params[:id])
  if user_signed_in?
    gon.push(
      session_id: @room.session_id,
      api_key: 453,
      token: current_user.tokens.last.token
    )
  elsif customer_signed_in?
    gon.push(
      session_id: @room.session_id,
      api_key: 453,
      token: current_customer.tokens.last.token,
      customer_id: current_customer.id
    )
  elsif @room.price == 0.0
    @token = OT.generate_token @room.session_id
    gon.push(
      session_id: @room.session_id,
      api_key: 453,
      token: @token
    )
  else
    @customer = Customer.new
  end
end

now I would like to move this into the rooms model. The issue that I'm having is that I'm having an if else based on if it's a user, customer or neither. How would I go about moving this into a model and still be able to validate this?

You could always use a PORO (Plain Old Ruby Object). Not only does it keep stuff clean, it helps a bunch in testing your app and keeping single responsibilities across your code. I'm sure you can do much better than below but this is just a starting point.

class YourController
  def show
    @room = Room.find(params[:id])
    # no clue where some stuff comes from
    pusher = RoomPusher.new @room, @token, gon
    pusher.push
  end
end

class RoomPusher
  include YourHelpers
  def initialize(room, token, endpoint)
    @endpoint = endpoint
    @room = room
    @token = token
  end

  def push
    if user_signed_in?
      @endpoint.push(
        session_id: @room.session_id,
        api_key: 453,
        token: current_user.tokens.last.token
      )
    elsif customer_signed_in?
      @endpoint.push(
        session_id: @room.session_id,
        api_key: 453,
        token: current_customer.tokens.last.token,
        customer_id: current_customer.id
      )
    elsif @room.price == 0.0
      @token = OT.generate_token @room.session_id
      @endpoint.push(
        session_id: @room.session_id,
        api_key: 453,
        token: @token
      )
    else
      @customer = Customer.new
    end
  end
end

I don't see why you would like to move this method to the model. (Are you using it from different places in your code? or just from this specific place?).

I would refactor this to the following:

def show
  @room = Room.find(params[:id])
  gon_args = { session_id: @room.session_id, api_key: 453, token: nil }
  if user_signed_in?
    gon_args.merge!(token: current_user.tokens.last.token)
  elsif customer_signed_in?
    gon_args.merge!(token: current_customer.tokens.last.token, customer_id: current_customer.id)
  elsif @room.price == 0.0
    gon_args.merge!(token: OT.generate_token(@room.session_id))
  else
    @customer = Customer.new
  end
  gon.push(gon_args) unless gon_args[:token].nil?
end
