underscorize_params

Installation

Add the Gem into your Gemfile

gem 'underscorize_params', github: 'monade/underscorize_params'

This gem allows you to send params to a Controller's action in camel case. It gets included inside ActionController::Base

ActionController::Base.include UnderscorizeParams::Controller if defined?(ActionController::Base)

Suppose you have these Controller and Model:

models/user.rb

class User < ActiveRecord::Base
  attribute :first_name, :String
  attribute :last_name, :String
end

controllers/users_controller.rb

class UsersController < ActionController::Base
  def create
    @user = User.new create_params

    if @user.save
      render json: @user
    else
      render json: @user.errors
    end
  end

  private

  def create_params
    params.permit(:first_name, :last_name)
  end
end

this gem allows you to call this controller's api with parameters in camel case, such as:

const params = {
  firstName: 'Friedrich',
  lastName: 'Nietzsche'
}

axios.post('/users', params)

the gem's job is very simple, received parameters get transformed into snake case in the before_action hook. Check out the code to find out, is very simple!
