Добавление функциональности событий в мой календарь Redmine с использованием стека битнами

Я хочу добавить, обновить и удалить событие в моем календаре Redmine (почти как в календаре Google). Я установил Redmine в стеке Bitnami. Но я не могу понять структуру кода, так как у меня нет надлежащей документации. Есть ли кто-нибудь, кто может мне в этом помочь. Приведенный ниже код - это мой контроллер календаря.

       class CalendarsController < ApplicationController
      menu_item :calendar
       before_action :find_optional_project

      rescue_from Query::StatementInvalid, :with => :query_statement_invalid

      helper :issues
      helper :projects
      helper :queries
      include QueriesHelper

      def show
if params[:year] and params[:year].to_i > 1900
  @year = params[:year].to_i
  if params[:month] and params[:month].to_i > 0 and params[:month].to_i < 13
    @month = params[:month].to_i
  end
end
@year ||= User.current.today.year
@month ||= User.current.today.month

@calendar = Redmine::Helpers::Calendar.new(Date.civil(@year, @month, 1), current_language, :month)
retrieve_query
@query.group_by = nil
@query.sort_criteria = nil
if @query.valid?
  events = []
  events += @query.issues(:include => [:tracker, :assigned_to, :priority],
                          :conditions => ["((start_date BETWEEN ? AND ?) OR (due_date BETWEEN ? AND ?))", @calendar.startdt, @calendar.enddt, @calendar.startdt, @calendar.enddt]
                          )
  events += @query.versions(:conditions => ["effective_date BETWEEN ? AND ?", @calendar.startdt, @calendar.enddt])

  @calendar.events = events
end

render :action => 'show', :layout => false if request.xhr?


end
end

Ниже приведен файл calender_helper.rb.

        module CalendarsHelper
  def link_to_previous_month(year, month, options = {})
    target_year, target_month = if month == 1
                                  [year - 1, 12]
                                else
                                  [year, month - 1]
                                end

    name = if target_month == 12
             "#{month_name(target_month)} #{target_year}"
           else
             "#{month_name(target_month)}"
           end

    # \xc2\xab(utf-8) = «
    link_to_month(("\xc2\xab " + name), target_year, target_month, options)
  end

  def link_to_next_month(year, month, options = {})
    target_year, target_month = if month == 12
                                  [year + 1, 1]
                                else
                                  [year, month + 1]
                                end

    name = if target_month == 1
             "#{month_name(target_month)} #{target_year}"
           else
             "#{month_name(target_month)}"
           end

    # \xc2\xbb(utf-8) = »
    link_to_month((name + " \xc2\xbb"), target_year, target_month, options)
  end

  def link_to_month(link_name, year, month, options = {})
    link_to(link_name, {:params => request.query_parameters.merge(:year => year, :month => month)}, options)
  end
end

Ниже представлен вид show.html.erb.

Это единственный код, связанный с календарем в routes.rb

      get '/projects/:project_id/issues/calendar', :to => 'calendars#show', :as => 'project_calendar'
      get '/issues/calendar', :to => 'calendars#show'
