ruby-on-rails - 我希望能够在 Rails 应用程序的日历上标记开始日期和结束日期之间的日期

Question

问题是我有一个 Rails 应用程序，它使用日历助手在我的日历上绘制 leave_start 和 leave_end。我希望能够标记两者之间的日期我已经尝试了一些事情，但到目前为止没有运气我能够让 leave_start 和 leave_end 出现但是，到目前为止无法标记两者之间的日期。任何帮助将不胜感激!!!!

这是我到目前为止尝试过的。

这是我的入口 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

举个例子: 我的 leave_start 日期是 2015-05-25

我的 leave_end 日期是 2015-05-29

两个日期之间的天数是这样的

离开_开始 2015-05-25

2015-05-262015-05-272015-05-28

离开 2015-05-29

额外信息

这是我的日历助手

 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

这也是我的日历 View

 #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')

更新---

试过了

    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

在我看来

 #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')

出于某种奇怪的原因，我得到了这个错误...

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

我附上了我的日历的屏幕截图，它显示了开始日期和结束日期，我希望它们之间的日期也显​​示出来。

Answer 1

require 'date'

start_date  = Date.parse('2015-05-25')
end_date    = Date.parse('2015-05-29')
date_range  = start_date..end_date
(date_range).map(&:to_s)

这将输出一个日期范围在 (start_date..end_date) 之间的数组，如下所示

例子:

["2015-05-25", "2015-05-26", "2015-05-27", "2015-05-28", "2015-05-29"]
