Rails-如何显示预订确认信息 [英] Rails - How to show booking confirmation details
问题描述
我目前正在使用Rails构建事件"应用，并且在预订确认方面以及如何向已预订参加活动的用户展示该内容方面有些挣扎.
I'm currently building an Events app using rails and I'm struggling a little with the booking confirmation side and how to show this to a user who has booked to attend an event.
这是我在bookings_controller中的代码-
This is my code in the bookings_controller -
class BookingsController < ApplicationController
before_action :authenticate_user!
def new
# booking form
# I need to find the event that we're making a booking on
@event = Event.find(params[:event_id])
# and because the event "has_many :bookings"
@booking = @event.bookings.new(quantity: params[:quantity])
# which person is booking the event?
@booking.user = current_user
end
def create
# actually process the booking
@event = Event.find(params[:event_id])
@booking = @event.bookings.new(booking_params)
@booking.user = current_user
if
@booking.paid_booking
flash[:success] = "Your place on our event has been booked"
@booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase)
redirect_to event_booking_path(@event)
else
flash[:error] = "Booking unsuccessful"
render "new"
end
end
def free_booking
if
@booking.free_booking
@booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase)
redirect_to event_booking_path(@event)
else
flash[:error] = "Booking unsuccessful"
render "new"
end
end
def show
@event = Event.find(params[:event_id])
@booking = @event.bookings.new
@booking = Booking.find_by(params[:booking_number])
end
def update
puts params
@event = Event.find(params[:event_id])
@booking = @event.bookings.new(booking_params)
if @booking.save
redirect_to event_booking_path , notice: "Booking was successfully updated!"
else
render 'new'
end
end
private
def booking_params
params.require(:booking).permit(:stripe_token, :booking_number, :quantity, :event_id, :stripe_charge_id, :total_amount)
end
end
这是免费&的表单视图付费预订-
Here's the form view for both free & paid bookings -
new.html.erb
<% if @booking.free_booking %>
<div class="col-md-6 col-md-offset-3" id="eventshow">
<div class="row">
<div class="panel panel-default">
<div class="panel-heading">
<h2>Confirm Your Booking</h2>
</div>
<%= simple_form_for [@event, @booking], id: "new_booking" do |form| %>
<% if @booking.errors.any? %>
<h2><%= pluralize(@booking.errors.count, "error") %> prevented this Booking from saving:</h2>
<ul>
<% @booking.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
<% end %>
<div class="form-group">
<p>Please confirm the number of spaces you wish to reserve for this event.</p>
<%= form.input :quantity, class: "form-control" %>
</div>
<p> This is a free event. No payment is required.</p>
<div class="panel-footer">
<%= form.submit :submit, label: 'Confirm Booking', class: "btn btn-primary" %>
<% end %>
</div>
<% else %>
<div class="col-md-6 col-md-offset-3" id="eventshow">
<div class="row">
<div class="panel panel-default">
<div class="panel-heading">
<h2>Confirm Your Booking</h2>
</div>
<%= simple_form_for [@event, @booking], id: "new_booking" do |form| %>
<div class="calculate-total">
<p>
Confirm number of spaces you wish to book here:
<input type="number" placeholder="1" name="booking[quantity]" min="1" value="1" class="num-spaces">
</p>
<p>
Total Amount
£<span class="total" data-unit-cost="<%= @event.price %>">0</span>
</p>
</div>
<span class="payment-errors"></span>
<div class="form-row">
<label>
<span>Card Number</span>
<input type="text" size="20" data-stripe="number"/>
</label>
</div>
<div class="form-row">
<label>
<span>CVC</span>
<input type="text" size="4" data-stripe="cvc"/>
</label>
</div>
<div class="form-row">
<label>
<span>Expiration (MM/YYYY)</span>
<input type="text" size="2" data-stripe="exp-month"/>
</label>
<span> / </span>
<input type="text" size="4" data-stripe="exp-year"/>
</div>
</div>
<div class="panel-footer">
<%= form.button :submit %>
</div>
<% end %>
<% end %>
</div>
</div>
</div>
还有我的模特-
Booking.rb
class Booking < ActiveRecord::Base
belongs_to :event
belongs_to :user
#before_create :set_booking_number
#before_validation :set_is_free
validates :quantity, presence: true, numericality: { greater_than_or_equal_to: 0 }
validates :total_amount, presence: true, numericality: { greater_than_or_equal_to: 0 }
validates :quantity, :total_amount, :booking_number, presence: true
def set_booking_number
self.booking_number = "MAMA" + '- ' + SecureRandom.hex(4).upcase
end
def set_is_free
set_is_free = total_amount.nil?
end
def free_booking
self.valid?
# Free events don't need to do anything special
if event.is_free?
save!
end
end
def paid_booking
# Don't process this booking if it isn't valid
self.valid?
# Paid events should charge the customer's card
#else
begin
self.total_amount = event.price_pennies * self.quantity
charge = Stripe::Charge.create(
amount: total_amount,
currency: "gbp",
source: stripe_token,
description: "Booking created for amount #{total_amount}")
self.stripe_charge_id = charge.id
self.booking_number = "MAMA" + '- ' + SecureRandom.hex(4).upcase
save!
rescue Stripe::CardError => e
errors.add(:base, e.message)
false
end
#end
#end
end
end
在我的表演视图中，我有以下代码可免费预订.在这种情况下，我只想确认(在此阶段)事件的标题，他们所请求的空间数量以及唯一的预订号-
In my show views I have the following code for free bookings. In this instance I simply want to confirm (at this stage) the event title, quantity of spaces they've requested and the unique booking number -
<h1>Hi there</h1>
<p>You have placed a booking on <%= @event.title %>.</p>
<p>You have reserved <%= @booking.quantity %> spaces for this event.</p>
<p>Your booking number is <%= @booking.booking_number %></p>
<p>We hope you have a wonderful time. Enjoy!</p>
此刻，当我进行考试预约时，我的想法是-
At the moment, when I perform a test booking I get this in my views -
因此，基本上，没有显示数量和数量的具体细节.在我的预订表中，我有一个event_id和user_id.即使每个预订都吸引了一个ID，但实际上我的预订表中没有我的booking_id作为列-这有什么区别吗?
So, basically, the specific details for quantity and number are not showing. In my bookings table I have an event_id and user_id. Even though each booking attracts an id I dont actually have booking_id as a column in my bookings table - does this make any difference?
schema.rb
create_table "bookings", force: :cascade do |t|
t.integer "event_id"
t.integer "user_id"
t.string "stripe_token"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "quantity", default: 1
t.integer "total_amount"
t.string "stripe_charge_id"
t.string "booking_number"
end
我敢肯定这很明显，但我没发现.我想念什么?
I'm sure this is something so obvious but I'm failing to spot it. What am I missing?
推荐答案
我不确定@booking是否持久保存到数据库中. new创建对象，但不保存.尝试使用先调用new然后save
I'm not sure @booking is persisted into the database. new creates the object but doesn't save it. Try using the create method which calls new then save
def update
@event = Event.find(params[:event_id])
if @event.bookings.create(booking_params)
redirect_to event_booking_path , notice: "Booking was successfully updated!"
else
render 'new'
end
end
修改
我实际上会像这样先使用new然后使用save
edit
I would actually use new and then save like so
def update
@event = Event.find(params[:event_id])
@booking = @event.bookings.new(booking_params)
if @booking.save
redirect_to event_booking_path , notice: "Booking was successfully updated!"
else
render 'new'
end
end
如果对象是否保存，save方法将返回true或false，其结果可以在条件中使用.
The save method will return with true or false if the object was saved or not, the result of this can be used in the conditional.
Create都将返回模型.这意味着if语句将始终为true.
Create on the other hand will return the model regardless of whether the object was saved or not. Which means the if statement will always be true.
因此，使用new + save将使您实际查看预订是否已保存或是否发生了其他错误.
So, using new + save will allow you to actually see if the booking was saved or not or if another error occurred.
