How to seperate Admin and User database in Rails

I have devise gem in my application. I've been playing around with making some tables etc. Now I want to separate the database for the admin and the database for the user. I know its one single database. But, I'm not sure how to get it going in Rails.

How do I retrieve a random GET request in Ruby on Rails 5?

I've created my REST API based on Michael Scott from the Office, so far if you go onto the main part of the API it displays all the quotes /api/v1/quotes/ and you can get individual ones if you add an id number such as /api/v1/quotes/5,but I want users to be able to get a random quote when they put in a GET request.

This would preferably be done with an extra part of the URL such as /api/v1/quotes/random.

I've looked at a lot online but I can't figure this out. Do I put my code into the quotes controller and create another function or do I have to put this somewhere else such as routes.db? Also do I put in the SQL function of RANDOM or is there a better and more efficient way to randomise it. My database only has 50 records in it and it's done in mysql2.

Thanks in advance.

It's my first time posting here as usually I hate asking for help as I think I can always figure it out myself but I'm extremely new to Ruby so I'm fairly clueless on how to solve this. If you need me to clarify my question then just let me know.

Ruby Rails equivalent in nodejs

I'm new in NodeJS I wanted to do the equivalent of this code which is coded in Ruby Rails.It is a survey that I must implement with my frontend

class SurveysController < ApplicationController
  before_action :authorize, only: [:create, :update, :destroy, :index]
  before_action :set_user, only: [:create, :destroy, :index]
  before_action :set_survey, only: [:show, :update, :destroy]

  # GET /surveys
  def index
    @surveys = @user.surveys

    render json: @surveys
  end

  # GET /surveys/1
  def show
    render json: @survey
  end

  # POST /surveys
  def create
    @survey = Survey.new(
      title: survey_params[:title],
      sub_title: survey_params[:sub_title],
      questions: survey_params[:questions].to_json,
      user: @user
    )

Initialization error expecting one amount seeing another

I'm trying to complete the card shuffle assignment and must use initialize and self in the code. I have defined what rank and suit mean but the program does not recognize that the variables are used, which they are. Then in the initialization, it says I have the wrong number of arguments

I tried changing the name of the items in the initialize code. I split @cards << (self.rank, self.suit) into 2 lines but made no difference. I moved the variable definitions inside the initialize code which helped with some messages but not the all.

This is the whole program

class Card
  attr_accessor :rank, :suit
  rank = [2, 3, 4, 5, 6, 7, 8, 9, 10, "Jack", "Queen", "King", "Ace"]
  suit = ["Hearts", "Diamond", "Clubs", "Spades"]

  def initialize(rank, suit)

    self.rank = rank
    self.suit = suit

  end

  def output_card
    puts "#{self.rank} of #{self.suit}"
  end

  #def self.random_card
   # Card.new(rand(rank, suit))
  #end
end

class Deck
  attr_accessor :rank, :suit

  #Generates the 4 suits of cards in each denomination
  def initialize(cards)
    cards = Card.new("rank", "suit")
    @cards = []
    @cards << Card.new(self.rank, self.suit)

  end

  #shuffles the deck of cards
  def shuffle
    unless @cards.empty?
      @cards.shuffle!
    end
  end


  #def self.top_card
    #Card.new(self.rank, self.suit)
  #end

  #Deals the cards from the top of the virtual deck.
  def deal
    @cards.each do |card|
      card.output
    end
  end  
end

deck = Card.new
deck.shuffle
deck.deal

This is the current error message I get.

Can stand-alone Rails server accept requests on multiple IP addresses

I want to know if I can launch a Rails server (Puma or otherwise) with options that will allow it to be hit over any IP address (127.0.0.1, localhost, network IP address, etc).

I think -b option only takes one IP address (not a wildcard or anything), and I have to restart it changing that option to allow connections over various IP addresses.

rails s -b 127.0.0.1 -p 3000

I would like to hit my server via both a browser on my machine and a browser on my iPhone on my network, and possibly a browser in a VM on my machine.

How to use rails update method for multiple object with collection

I am trying to update multiple objects with rails update method with update collection object as following codes:(couldn't really find the collection method)

def update

      @reiew = Review.find(reivew_params)
       review.update!(reivew_params)

        if @reivews.update(reivew_params)
        respond_to do |format|
        format.html { redirect_to reivew_path}
      end
    else
        respond_to do |format|
        format.html { notice: 'saved errors'}
      end
    end
  end
