Rails app Task with recurrence, list of Task and Calendar view

Hi! I got a Rails app that I need to add a Todo list(Task) and the Task has to be recurrence. I need you to build a rails 4.2 with ruby 2.2.0 with the task and then I can add it to my app. Im using erb, jquery and bootstrap Task Table name descriciption completed (boolean) manager_sign(attachment) client_sign(attachment) Just add it ill do the rest on the attachments class Task < ActiveRecord::Base has_many :schedules has_many :occurrences end # Holds my schedule object class Schedule < ActiveRecord::Base belongs_to :task end # Holds generated or manually created event occurrences class Occurrence < ActiveRecord::Base belongs_to :task end ----------------------------------- ice_cube to manage the occurrences calculation and stored the results in the occurrences table. I need to store each task occurrences for later create a history page and build some graphics.(not for thes project) Need to flag an event occurrence as canceled,completed,sign it or modify it independe from the others or have the ability to move the occurence and future occurence date. On each task I has a completed boolean that I need to mark and add the 2 attachment. Need to have to view one task of list and togget to calendar mode. use the recurring_select gem for the form. example app(dont have occurence independe) [login to view URL] This are the gems that I need to be work with [login to view URL] [login to view URL] [login to view URL] -------------------------------
