没有预约的团体

Question

下面的代码显示每小时约会的次数，如果没有预约可用，则显示'不约会'。

欲组连续“否预约”插槽根据时间

为例如，当前代码的输出为 -

10:00 AM to 11:00 AM -> No Appointment 11:00 AM to 12:00 PM -> No Appointment 12:00 PM to 01:00 PM -> No Appointment

我想输出是

10:00 AM to 01:00 PM -> No Appointment

该代码如下： -

<% @time_group = ['6:00:00','7:00:00','8:00:00','9:00:00','10:00:00','11:00:00','12:00:00','13:00:00','14:00:00','15:00:00','16:00:00','17:00:00','18:00:00','19:00:00','20:00:00','21:00:00','22:00:00','23:00:00'] %> 

#Loop through each hour in @time_group 
<% @time_group.each_with_index do |t,index| %> 
    <% t1 = Time.parse(t) %> 
    <% t2 = Time.parse(t) + 3600 %> 
    <% @booked = Appointment.where(start_time: t1..t2 %> 

    #Show time interval e.g 1:00 PM to 2:00 PM 
    <%= Time.parse(t).strftime('%I:%M %p') %> to <%= (Time.parse(t) + 3600).strftime('%I:%M %p') %> 

    #if appointment is available show appointment else show no appointment 
    <% if @booked.size > 0 %> 

    <% @booked.each do |app| %> 
     <%= app.start_time.strftime('%I:%M') %> 
    <% end %> 

    <% else %> 

    No Appointment 

    <% end %> 
<% end %> 

Answer 1

首先，人们可能准备数组：

@time_group = ['6:00:00','7:00:00', ...] 
@stacked = @time_group.each_with_object([]) do |start, memo| 
    range = Time.parse(start)..Time.parse(start)+3600 
    booked = Appointment.where(start_time: range) 
    if memo.empty? || !booked.empty? || !memo.last.last.empty? 
    memo << [range, booked] # no sequenced empty slots 
    else 
    memo << [memo.pop.begin..range.end, booked] # merge ranges 
    end 
end.to_h # { ranges => booked } 

现在，让我们将他们输出：

<% @stacked.each do |range, booked| %> 
    ..... 
<% end %>

尝试这样

<% @time_group = ['6:00:00','7:00:00','8:00:00','9:00:00','10:00:00','11:00:00','12:00:00','13:00:00','14:00:00','15:00:00','16:00:00','17:00:00','18:00:00','19:00:00','20:00:00','21:00:00','22:00:00','23:00:00'] %> 

#Loop through each hour in @time_group 
<% @time_group.each_with_index do |t,index| %> 
    <% t1 = Time.parse(t) %> 
    <% t2 = Time.parse(t) + 3600 %> 
    <% @booked = Appointment.where(start_time: t1..t2) %> 


    #It will holds the No Appointment Timings into it 
    no_appointment_array = [] 

    #if appointment is available show appointment else show no appointment 
    <% if @booked.size > 0 %> 

    #Calling the Function 
    display_no_appointment(no_appointment_array) if not no_appointment_array.empty? 


    #Show time interval e.g 1:00 PM to 2:00 PM 
    <%= Time.parse(t).strftime('%I:%M %p') %> to <%= (Time.parse(t) + 3600).strftime('%I:%M %p') %> 

    <% @booked.each do |app| %> 
     <%= app.start_time.strftime('%I:%M') %> 
    <% end %> 

    <% else %> 

    no_appointment_array << [Time.parse(t).strftime('%I:%M %p'), (Time.parse(t) + 3600).strftime('%I:%M %p')] 

    <% end %> 
<% end %> 


def display_no_appointment(no_appointment_array) 
    puts "#{no_appointment_array.first[0]} to #{no_appointment_array.last[1]} -> No Appointment" 

    #It Clears all Previous No Appointment 
    no_appointment_array.clear 

end

首先，我建议你，如果使用“@ booked.present？而不是'if @ booked.size> 0'

你试过类似的东西吗？ 我还没有测试这个代码，它几乎是一个可能的解决方案的想法。 希望它对您有所帮助。

<% no_appointment_starts_at = nil %> 
<% no_appointment_ends_at = nil %> 

<% @time_group.each_with_index do |t,index| %> 
    <% t1 = Time.parse(t) %> 
    <% t2 = Time.parse(t) + 3600 %> 
    <% @booked = Appointment.where(start_time: t1..t2 %> 

    #Show time interval e.g 1:00 PM to 2:00 PM 


    #if appointment is available show appointment else show no appointment 
    <% if @booked.present? %> 

    <% @booked.each do |app| %> 
     <% unless no_appointment_ends_at.blank? %> 
      <%= Time.parse(no_appointment_starts_at).strftime('%I:%M %p') %> to <%= (Time.parse(no_appointment_ends_at) + 3600).strftime('%I:%M %p') %> 
      <% no_appointment_ends_at = nil%> 
     <% end %> 
     <%= Time.parse(t).strftime('%I:%M %p') %> to <%= (Time.parse(t) + 3600).strftime('%I:%M %p') %> 
     <%#= app.start_time.strftime('%I:%M') %> 
     <% no_appointment_starts_at = t2 %> 
    <% end %> 

    <% else %> 
     <% last_appointment_ends_at = t2 %> 
    <% end %> 
<% end %>
