Question

我正在使用Rails构建一个活动应用程序，并试图掌握预订确认流程。目前我的MVC似乎到处都是。

这是我的免费活动预订表格，纯粹需要用户所需的空间数量 -

new.html.erb

<%= 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>

这是我的控制器代码 -

bookings_controller.rb

before_action :find_booking, only: [:show, :update]
before_action :find_event, only: [:show, :update]
before_action :authenticate_user!  

def new
    @event = Event.find(params[:event_id])
    @booking = @event.bookings.new(quantity: params[:quantity])
    @booking.user = current_user
end

def create
    @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, @booking)
    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, @booking)
    else
        flash[:error] = "Booking unsuccessful"
        render "new"
    end
end

def show
    @event = Event.find(params[:event_id])
    @booking = Booking.find_by(booking_number: params[:booking_number])
end

def update
    if @booking.save
        redirect_to event_booking_path(@event, @booking) , 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

def find_booking
    @booking = Booking.find_by(booking_number: params[:booking_number])
end

def find_event
    @event = Event.find(params[:event_id])
end

当我在控制台上查看预订时，保存的唯一参数是event_id和user_id - 免费预订不会保存数量，但会为付费预订保存。此外，我的预订确认展示视图包含以下属性 -

<%= @event.title %>
<%= @booking.quantity %>
<%= @booking.booking_number %>

在这三个属性中，只有event.title显示在页面上，其他两个属性根本不显示。我完全不知道这是怎么回事。如果有人能看到我无法做到的事情，我将不胜感激。

Rails - 没有保存到数据库的参数
