How Can I Master Ruby on Rails and Learn Advanced Features Like Hotwire, Elasticsearch, and Datatables? [closed]

I'm a software developer with 1.5 years of experience in Ruby on Rails. My question is: how can I become a master in Ruby on Rails? I need to learn advanced features like Hotwire, Elasticsearch, Datatables, and many more. Any guidance or resources would be greatly appreciated!

I have tried many resources to learn but found that they all teach things differently, especially for Elasticsearch and Datatables. In my current company, they have a specific way of implementing these features, which I haven't been able to find in external resources. Here’s an example of how we set up Datatables with "import command."

Below is the index method in Admins::TrustBudgetsController:

ruby

class Admins::TrustBudgetsController < Admins::BaseController  before_action :set_trust_budget, only: [:show, :approve, :deny, :approve_request]  def index    @trust_budgets = UserTrustBadge.all    respond_to do |format|      format.html      format.json { render json: TrustBudgetsDatatable.new(view_context, recordset: @trust_budgets) }    end  endend

Here is the Datatable class in app/datatable/user_budgets_datatable.rb:

class TrustBudgetsDatatable  include Pagy::Backend  include ApplicationHelper  delegate :content_tag, :params, :link_to, :admins_trust_budget_path, to: :@view  def initialize(view, options = {})    @view = view    @options = options  end  def as_json(options = {})    {      sEcho: params[:sEcho].to_i,      iTotalRecords: @options[:recordset].count,      iTotalDisplayRecords: total_count,      aaData: data    }  end  private  def data    trust_budgets.map do |p|      ["#{p.user.user_name} request for #{p.user.user_trust_badge.category_name} badge",        content_tag(:span, p.permission_status, class: status_color(p.permission_status)),        content_tag(:div) do          content = ''          content += "<span class='text-uppercase p-1'>"          content += link_to "View", admins_trust_budget_path(p.user.user_trust_badge.id), class: "text-red-gradient", data: { turbo_frame: "modal_content" }          content += '</span>'          content.html_safe        end      ]    end  end  def trust_budgets    @trust_budgets ||= fetch_trust_budgets  end  def fetch_trust_budgets    trust_budgets = @options[:recordset]    if params[:sSearch].present?      trust_budgets = trust_budgets.joins(:user, :post)                                    .where("users.user_name ILIKE :search OR CAST(posts.number AS TEXT) ILIKE :search OR CAST(total_amount AS TEXT) ILIKE :search OR CAST(permission_status AS TEXT) ILIKE :search", search: "%#{params[:sSearch]}%")    end    if params[:iDisplayLength] == '-1'      trust_budgets = trust_budgets.reorder("#{sort_column} #{sort_direction}")    else      @pagy, trust_budgets = pagy(trust_budgets.reorder("#{sort_column} #{sort_direction}"), items: per_page, page: page)    end    trust_budgets  end  def total_count    trust_budgets.count    @pagy ? @pagy.count : trust_budgets.count  end  def page    params[:iDisplayStart].to_i / per_page + 1  end  def per_page    params[:iDisplayLength].to_i > 0 ? params[:iDisplayLength].to_i : 10  end  def sort_column    columns = %w[id permission_status]    sorting_column_index = params[:iSortCol_0].to_i    columns[sorting_column_index]  end  def sort_direction    params[:sSortDir_0] == "asc" ? "asc" : "desc"  end  def status_color(status)    case status    when 'Pending''text-warning'    when 'Approved''text-success'    when 'Denied''text-danger'    else'text-secondary'    end  endend
