Understanding the Components

Before diving into the implementation, let's understand the key components:

• Trigger: The specific event that causes a reward to be created (e.g., completing a trial booking)

• Source: The original cause that led to the reward (typically the referral)

• Recipient: The user or household that receives the reward

• Amount: The reward value, stored in cents for precision using the money-rails gem

The Core: The Reward Model

At the heart of our system is the Reward model:

class Reward < ApplicationRecord
  belongs_to :recipient, polymorphic: true
  belongs_to :trigger, polymorphic: true, optional: true
  belongs_to :source, polymorphic: true, optional: true

  monetize :amount_cents

  enum reason: {
    trial_start: 'trial_start',
    sub_complete: 'sub_complete',
    signup_discount: 'signup_discount'
  }, _prefix: true

  scope :unredeemed, -> { where(redeemed_at: nil) }

  # ... methods for creating specific rewards ...
end

The Rewardable Concern

To make it easy to add reward functionality to different models, we created a Rewardable concern:

# app/models/concerns/rewardable.rb

module Rewardable
  extend ActiveSupport::Concern

  included do
    has_many :rewards, as: :recipient
  end

  def total_earned
    Money.new(rewards.sum(:amount_cents), "CAD")
  end

  def unredeemed_rewards
    rewards.unredeemed
  end

  def redeem_rewards!
    unredeemed_rewards.update_all(redeemed_at: Time.current)
  end
end

Extending the Referral Model

We extended the Refer gem's Referral model to integrate with our reward system:

module ReferralExtensions
  extend ActiveSupport::Concern

  included do
    has_many :rewards, as: :source
  end

  def create_trial_rewards(trial_booking)
    Reward.create_for_trial_start(self, trial_booking)
  end

  def complete_subscription(subscription)
    Reward.create_for_sub_complete(self, subscription)
  end
end

# In config/initializers/refer.rb
Rails.application.config.to_prepare do
  Refer::Referral.include ReferralExtensions
end

Triggering Rewards

We set up our Booking model to trigger rewards when a booking is completed, as an example:

class Booking < ApplicationRecord
  after_save :create_trial_start_reward, if: :status_changed_to_completed?

  private

  def create_trial_start_reward
    referral = Refer::Referral.find_by(referred: household.owner)
    Reward.create_for_trial_start(referral, self) if referral
  end

  def status_changed_to_completed?
    saved_change_to_status? && completed?
  end
end

Conclusion

This flexible reward system allows us to easily add new types of rewards and associate them with different actions in our application. The use of polymorphic associations provides the flexibility to link rewards to various models, while the money-rails gem ensures precise handling of monetary amounts. The system has proven to be robust and easily extendable as our referral program grows.

The combination of the Refer gem for handling referrals and our custom reward system has created a powerful tool for incentivizing user growth and engagement on our platform.

Beyond the nostalgia of family recipes and the comfort of familiar aromas, home cooking offers undeniable benefits: healthier eating, cost savings, and a stronger connection with the people you share your table with.

But, life is busy, and sometimes the thought of cooking feels like another chore. There are ways to make this chore easier and turn it into a lifestyle habit.

After all, the rewards of cooking at home are worth exploring and can be a game-changer for your health, happiness, and wallet.

The benefits of cooking at home

Cooking at home is an investment in your physical and financial well-being. A 2025 survey by The Harris Poll found that 89% of consumers believe cooking meals at home is one of the best ways to save money on food.

But the savings don’t stop there. Home cooking helps you manage what goes into your meals. According to Harvard Health, people who prepare meals at home tend to consume more fruits and vegetables and less sugar and fat. From choosing fresh, unprocessed ingredients to controlling portion sizes, the health benefits are clear:

Improved nutrition

When you cook at home, you control what goes into your meals, allowing you to prioritize fresh, whole ingredients over processed foods. For example, making your own spaghetti sauce lets you skip the excess sugar and sodium often found in store-bought jars. Similarly, a homemade salad dressing made with olive oil, vinegar, and a dash of mustard is a much healthier option than bottled dressings laden with preservatives and unhealthy fats.

Cooking also allows you to adjust recipes for your dietary needs. Whether you're reducing salt to manage high blood pressure or avoiding allergens like gluten or dairy, home cooking gives you complete control over every bite.

Reduced risk of chronic diseases

Regularly cooking meals with nutrient-dense ingredients can significantly improve your health and reduce the risk of chronic illnesses. For instance:

• Swapping out red meat for lean proteins like chicken or fish can lower cholesterol levels, a key factor in preventing heart disease.

• Preparing meals rich in fiber—such as lentil soup or whole-grain pasta—supports better digestion and reduces the risk of type 2 diabetes.

• Incorporating heart-healthy ingredients, like avocados, nuts, and olive oil, into your cooking mimics the benefits of the Mediterranean diet, which studies show is linked to lower rates of cardiovascular disease.

Healthier habits

Cooking at home encourages mindfulness in ways restaurant meals or fast food can’t. The act of measuring ingredients, understanding portion sizes, and exploring the nutritional value of various foods naturally fosters healthier choices. For example:

• If you're preparing a stir-fry, you’ll likely choose fresh vegetables like broccoli, bell peppers, and snap peas instead of the fried, heavily salted options available at many takeout spots.

• By experimenting with new recipes, you might discover how simple swaps—like Greek yogurt instead of sour cream—can boost protein and reduce unhealthy fats in your meals.

Each home-cooked meal is an opportunity to prioritize your health, experiment with real food, and build lasting habits.

Overcoming obstacles to cooking at home

Cooking at home has undeniable benefits, but it’s not without challenges. For many, finding the time, energy, or skills to prepare home-cooked meals can feel overwhelming. That’s where services like Cravd come in, letting you hire a home chef. With affordable home chef options starting at just $39, Cravd simplifies meal preparation, allowing you to enjoy healthy, home-cooked meals without the hassle.

But a home chef isn’t the only way to overcome these obstacles. Let’s explore how to tackle common challenges, with a mix of practical tips and testimonials that show what’s possible.

“I barely have time to cook with my busy schedule.”

Time constraints are one of the biggest hurdles to home cooking. Instead of relying on fast food or processed options, try solutions like batch cooking or meal prepping. Dedicate a few hours on the weekend to prepare staples like roasted vegetables, grilled chicken, or soups that can be reheated during the week. Another tip: plan your meals in advance to minimize last-minute decisions.

Cravd can be a game-changer for those whose schedules are packed. By hiring a home chef, you save hours otherwise spent on grocery shopping, cooking, and cleaning. One Cravd customer, Shreema, shared:

“As busy professionals, finding the time to cook healthy meals was always a challenge for us. Cravd has made life so much easier by taking care of the cooking, allowing us to save valuable time without compromising on quality.”

“I’m too exhausted to cook after a long day.”

Cooking at the end of a tiring day can feel like an uphill battle. To make it easier, simplify the cooking process with quick recipes that require minimal effort, like a one-pan chicken and veggies or a 15-minute stir-fry. Keeping a well-stocked pantry with essentials like olive oil, spices, and grains can also cut down on decision fatigue.

Alternatively, let Cravd handle the cooking for you. Imagine coming home to a kitchen that smells of freshly cooked meals without lifting a finger. As Malika, another Cravd customer, said:

“Having wholesome meals at home helped us save a lot by cutting down on eating out. The convenience and nutrition of home-cooked food have been a game-changer.”

“I’ve never learned how to cook, so I wouldn’t know where to start.”

Learning to cook can seem intimidating, but it doesn’t have to be. Start with a few simple recipes that use everyday ingredients, like scrambled eggs, pasta with a homemade sauce, or a basic vegetable soup. Apps, cooking classes, or YouTube tutorials can also provide step-by-step guidance.

If you’d rather learn with hands-on help, Cravd’s chefs can teach you new recipes tailored to your preferences, ensuring you gain both confidence and skills in the kitchen.

“Even when I cook, my family won’t eat it.”

Picky eaters can make mealtime frustrating, but there are ways to win them over. Try involving family members in the cooking process, letting them choose ingredients or help with simple tasks. Presentation can also make a difference—calling a vegetable-packed soup “rainbow stew” might encourage kids to try it.

Cravd chefs are skilled at creating meals that balance nutrition with taste, ensuring the whole family enjoys the food. As one customer shared:

“The meals are always tailored to our preferences. It’s made it so much easier to get everyone on board with healthy eating.”

“Hiring a chef sounds expensive. I can’t afford that.”

Many people assume personal chef services are a luxury, but Cravd’s model proves otherwise. With trial sessions starting at just $39 and regular bookings as low as $50, Cravd makes it accessible to enjoy home-cooked meals without breaking the bank. Plus, consider the cost savings from reduced eating out, wasted groceries, and better health.

With these strategies and services like Cravd, cooking at home doesn’t have to be a daunting task. Instead, it becomes a manageable, even enjoyable, way to improve your diet and lifestyle.

Quick tips for getting started

Ready to make home cooking a habit? Here’s how:

1. Plan ahead: Create a weekly meal plan to simplify grocery shopping and avoid last-minute fast food.

2. Start small: Focus on recipes with fewer than 10 ingredients to build confidence.

3. Batch cook: Prepare large portions of staples like soups or roasted vegetables for easy reheating.

4. Invest in the right tools: A sharp knife, quality cooking oil like extra virgin olive oil or cold pressed peanut oil, and a sturdy cutting board can make the cooking process smoother.

5. Hire a home chef: Cravd’s chefs can teach you cooking skills, prepare meals, or handle the heavy lifting when life gets hectic.

6. Make it fun: Experiment with new recipes or host a “cook-off” with friends to keep things exciting.

The future of food is homemade

In a world where life moves fast and time feels limited, the idea of home-cooked meals can seem like a distant dream. But Cravd was created to bridge this gap. Born from the shared experiences of two busy dads, Cravd understands the challenges families face in balancing health, time, and the daily grind of meal preparation.

By making home cooking accessible, personalized, and hassle-free, Cravd is helping people rediscover the joy and benefits of home-cooked meals. With dedicated chefs preparing meals right in your kitchen, you gain time for what truly matters, whether it’s connecting with family, pursuing hobbies, or simply unwinding at the end of the day.

The future of food isn’t just about convenience, it’s about personalization and care. Home-cooked meals meet these needs perfectly, offering a healthier, more sustainable way to eat. Cravd embodies this vision, helping families reclaim their kitchens and embrace the health and happiness that come with real food, made just for them.

Setting Up the Refer Gem

First, we added the Refer gem to our Gemfile:

gem "refer"

After running bundle install, we generated the necessary migrations:

rails generate refer:install
rails db:migrate

This set up the basic database structure for tracking referrals.

Configuring the Referral Code Generator

We customized the referral code generation in an initializer file:

# config/initializers/refer.rb

Refer.code_generator = lambda do |referrer|
  get_existing_code(referrer).presence || generate_new_code(referrer.id)
end

Refer.param_name = :code

private

def get_existing_code(referrer)
  referrer.referral_codes.last&.code
end

def generate_new_code(referrer_id)
  letters = ("A".."Z").to_a.sample(4).join
  padded_id = referrer_id.to_s.rjust(4, "0")
  "#{letters}-#{padded_id}"
end

This creates unique, readable codes combining random letters and the referrer's ID.

Integrating with User Model

We added the has_referrals macro to our User model:

class User < ApplicationRecord
  has_referrals
  # ... other code ...
end

Handling Referrals in the Controller

We updated our RegistrationsController to handle referrals during sign up:

class RegistrationsController < ApplicationController
  def create
    @user = User.new(user_params)
    if @user.save
      refer @user
      start_new_session_for @user
      send_welcome_email
      redirect_to after_authentication_url, notice: "Welcome to Cravd!"
    else
      render :new, status: :unprocessable_content
    end
  end
end

Handling Referrals in the Controller

In our ReferralsController, we implemented two key methods to manage referral codes and cookies:

class ReferralsController < ApplicationController
  set_referral_cookie only: [:show], if: -> { Current.user.blank? && !browser.bot? }
  before_action :set_referral_code, only: [:index, :show]

  private

  def set_referral_code
    return unless Current.user
    @referral_code = Current.user.referral_codes.last || Current.user.referral_codes.create
  end
end

The set_referral_cookie method is used to store the referral code in a cookie when it's present in the request parameters, and set_referral_code method is used to create or retrieve a referral code for the current user. It’s used in the referrals controllers where I want to display the user's referral code.

Conclusion

With these pieces in place, we now have a functional referral system. Users can generate unique referral codes, share them, and we can track successful referrals. This implementation provides a solid foundation for our referral program, which we'll build upon to create a comprehensive reward system.

But the reality is much more accessible—and surprisingly relatable. Whether you’re a busy parent, a working professional, or someone who simply wants to enjoy home-cooked meals without the hassle, a home chef service is the solution you never knew you needed.

What is a home chef service?

A home chef service brings the expertise of a chef directly to your kitchen. And here’s the thing: these chefs aren’t just culinary experts—they’re people like you and me. They understand the importance of wholesome, tasty meals made with care. Here’s how it typically works:

• Personalized meal prep: Your chef creates meals tailored to your dietary preferences, restrictions, and cravings. As they get to know you and your taste buds better, they’ll even suggest personalized menu options.

• Time-saving convenience: They handle grocery shopping if you choose, cooking, and even cleaning up after themselves.

• Flexible scheduling: You decide how often they visit, whether it’s for weekly meal prep or special occasions.

With an online marketplace like Cravd, a home chef service is no longer a luxury reserved for a few. It’s a practical choice for anyone who values time, health, and quality dining experiences at home.

Why a home chef service isn’t just for celebrities

The idea of hiring an in-home chef often conjures images of high-end lifestyles, but the truth is far from that stereotype. A home chef service is about solving everyday problems:

• Busy schedules: Juggling work, family, and personal time leaves little room for meal prep and setting daily menus that the family will actually enjoy.

• Specialized diets: From gluten-free to keto, chefs can craft meals to meet your needs.

• Family-focused time: Instead of spending hours in the kitchen, you can enjoy more meaningful moments with loved ones.

Cravd’s mission makes it clear: Give busy families access to home-cooked meals.

You don’t have to be Oprah to enjoy the perks of a home chef experience. At just $39 for your first session and subscription options as low as $50 per booking, it’s an affordable way to upgrade your daily routine.

The people behind the service: Home chefs like you and me

What sets a home chef service apart is the people behind it. These chefs are passionate about food and understand the value of home-cooked meals. They aren’t just preparing food; they’re bringing the warmth of home to your table. Here’s what they bring:

• A love for cooking: Many chefs are inspired by family traditions and authentic recipes.

• Commitment to hygiene: Just like you, they prioritize cleanliness and safety in the kitchen.

• A personal touch: They’re not just cooking meals, they’re creating an experience tailored to your preferences.

As Prajakta, an air hostess-turned-home chef, says

“Being a mom myself, I relate to the difficulties that parents face in putting healthy meals on the table, especially if they’re working full-time. I find it so rewarding to be able to help them out with meals that not just the adults but the kids relish as well.”

It’s a win-win, because Prajakta earns an income doing what she loves, and her customers get personalized, healthy, home-cooked meals.

The benefits of a home chef service

Choosing a home chef service isn’t just about convenience. It’s about choosing your health and making time for what matters. Malika and her husband, a Toronto-based couple, tried out a home chef service and vowed to never go back.

“We've transformed our health and lifestyle. My husband lost 6 kgs, and we both feel more energized and healthier than ever. Having wholesome meals at home helped us save a lot by cutting down on eating out.”

Just like Malika experienced, here are the obvious benefits of having someone cook in your own home:

1. Authentic home-cooked meals

Your chef will use fresh ingredients and traditional recipes to create dishes that taste like they’re straight from your grandmother’s kitchen. Whether you’re craving comfort food or want to explore new cuisines, the possibilities are endless and you have complete control over the ingredients. No more guesswork or upset tummies!

2. More time for what matters

Think about all the time spent grocery shopping, cooking, and cleaning. With a home chef, those hours are yours to reclaim. Spend them with family, pursue hobbies, or simply relax after a long day.

3. Environmental impact

Unlike meal kits or takeout, a home chef service eliminates unnecessary packaging waste or worrying about the environmental impact of using styrofoam and plastic. Cravd’s zero-waste approach means you can enjoy delicious meals guilt-free, knowing you’re making an eco-friendly choice.

Cost Surge

What started as an "elegant solution" quickly became a concern. By July 2024, ElastiCache costs had skyrocketed to $120.53, pushing our total AWS expenses to $197.811. The graph clearly shows how ElastiCache dominated our infrastructure costs, accounting for over 60% of monthly expenses.

The Solution

After successfully implementing Solid Queue and following the release of Solid Cable at Rails World 2024, we pivoted to this database-backed alternative for real-time features. This eliminated our Redis dependency while maintaining full functionality. The data shows remarkable improvements:

• Monthly AWS costs decreased from $197.81 to $74.55

• Infrastructure costs reduced by approximately 62%

• Complete elimination of the $120.53 monthly ElastiCache expense

Beyond the Numbers

The switch to Solid Queue significantly reduced our infrastructure complexity. By eliminating Redis, we've simplified our stack, making it easier to maintain, debug, and scale. This change aligns with Rails' philosophy of convention over configuration, keeping things simple and streamlined. Following this success, we integrated Solid Cache, completing the Solid trifecta.

Key Takeaway

This migration reinforces a valuable lesson: staying aligned with framework defaults often leads to both technical and financial benefits. Our tech stack is now simpler, more maintainable, and more cost-effective while maintaining all the functionality our application requires.

The cost breakdown graph demonstrates this transformation, showing sustained lower costs from October 2024 onward, with stable expenses around $75/month
