I want to be able to mark dates between start date and end date of my calendar in rails app

Question: I have a rails app that uses the calendar helper to plot plot_start and leave_end on my calendar. I want to be able to mark dates in between I've tried a few things and still have no luck that I could however get leave_start and leave_end to show, but can't mark dates in between. Any help would be very much appreciated !!!!

Here is what I have tried so far.

This is my input controller ...

class EntryController < ApplicationController


def index
   entry_by_start_date = Entry.where("emp_id = ?", 'BILL').group_by {|i| i.leave_start.to_date
   entry_by_end_date = Entry.where("emp_id = ?", 'BILL').group_by {|i| i.leave_end.to_date
   @entry_by_date = entry_by_start_date.merge(entry_by_end_date) {|key, oldval, newval| newval }

   ####^ this works but will only plot leave_start and leave_end on my calendar.

   # this is how I tried to plot all the dates between 
   ## leave_start and leave_end to be plotted on my calendar as well

   e_by_s = Entry.where("emp_id = ?", 'BILL').pluck(:leave_start)
   e_by_e = Entry.where("emp_id = ?", 'BILL').pluck(:leave_end)
   r_j = e_by_s.to_s
   r_g = e_by_e.to_s
   p_g = r_j.to_date
   t_g = r_g.to_date
   days_between = p_g.upto(t_g) { |date| puts date }
   @entry_by_all_dates = days_between.merge(days_between) {|key, oldval, newval| newval }
   @date = params[:date] ? Date.parse(params[:date]) : Date.today
   respond_to do |format|
     format.html # index.html.haml
     format.json { render :json => @entry }
   end
 end

      

        
        
        
      

    

So for example: my vacation date will be 2015-05-25

my vacation date will be 2015-05-29

days between both dates will be

leave_start 2015-05-25

2015-05-26 2015-05-27 2015-05-28

leave_end 2015-05-29

Additional Information

here is my calendar helper

 module CalendarHelper
   def calendar(date = Date.today, &block)
     Calendar.new(self, date, block).table
   end

   class Calendar < Struct.new(:view, :date, :callback)
     HEADER = %w[Sun Mon Tues Wed Thur Fri Sat]
     START_DAY = :sunday

     delegate :content_tag, to: :view

     def table
       content_tag :table, class: "calendar" do
         header + week_rows
     end
   end

   def header
     content_tag :tr do
      HEADER.map { |day| content_tag :th, day }.join.html_safe
   end
 end

 def week_rows
   weeks.map do |week|
     content_tag :tr do
       week.map { |day| day_cell(day) }.join.html_safe
    end
  end.join.html_safe
end

def day_cell(day)
  content_tag :td, view.capture(day, &callback), class: day_classes(day)
end

def day_classes(day)
  classes = []
  classes << "today" if day == Date.today
  classes << "notmonth" if day.month != date.month
  classes.empty? ? nil : classes.join(" ")
end

def weeks
  first = date.beginning_of_month.beginning_of_week(START_DAY)
  last = date.end_of_month.end_of_week(START_DAY)
  (first..last).to_a.in_groups_of(7)
end

      

        
        
        
      

    

Also here is my take on my calendar

 #entry
   %h2#month
     = link_to "<", date: @date.prev_month
     = @date.strftime("%B %Y")
     = link_to ">", date: @date.next_month
   = calendar @date do |date|
     = date.day
     - if @entry_by_date[date]
       %ul
         - @entry_by_date[date].each do |entry|
           %li
             %span.u= entry.emp_id
           %ul
             %span.u= entry.leave_start.strftime('%m/%d')
             %span.u --
             %span.u= entry.leave_end.strftime('%m/%d')
     -elsif @entry_by_all_dates
       %ul
         - @entry_by_all_dates[date].each do |t|
           %li
             %span.u= t.emp_id
           %ul
             %span.u= t.leave_start.strftime('%m/%d')
             %span.u --
             %span.u= t.leave_end.strftime('%m/%d')

      

        
        
        
      

    

Update ---

Tried this

    e_by_s = Entry.where("emp_id = ?", 'BILL').pluck(:leave_start).first
    e_by_e = Entry.where("emp_id = ?", 'BILL').pluck(:leave_end).first
    r_j = e_by_s.to_s
    r_g = e_by_e.to_s
    p_g = r_j.to_date
    t_g = r_g.to_date
    @days_between = p_g..t_g
    @entry_by_all_dates = (@days_between).map(&:to_s)
    @date = params[:date] ? Date.parse(params[:date]) : Date.today
    respond_to do |format|
      format.html # index.html.haml
      format.json { render :json => @entry }
    end
  end

      

        
        
        
      

    

and in my opinion

 #entry
   %h2#month
     = link_to "<", date: @date.prev_month
     = @date.strftime("%B %Y")
     = link_to ">", date: @date.next_month
   = calendar @date do |date|
      = date.day
      - if @entry_by_date[date]
        %ul
          - @entry_by_date[date].each do |entry|
            %li
              %span.u= entry.emp_id
            %ul
              %span.u Type --
              %span.u= entry.indirect_id
            %ul
              %span.u= entry.leave_start.strftime('%m/%d')
              %span.u --
              %span.u= entry.leave_end.strftime('%m/%d')
            %ul
              %span.u Shift --
              %span.u= entry.am_pm
          - @entry_by_all_dates[date].each do |t|
            %li
              %span.u= t.emp_id
            %ul
              %span.u= t.leave_start.strftime('%m/%d')
              %span.u --
              %span.u= t.leave_end.strftime('%m/%d')

      

        
        
        
      

    

For some odd reason I am getting this error ...

     ActionView::Template::Error (can't convert Date into Integer):

      

        
        
        
      

    

I have attached a screenshot of my calendar showing the start and end dates. I want the dates in between to display as well.
