Question

我正在尝试为我的Spree 1.2商店添加一个额外的步骤，这将允许客户创建订阅。我已插入步骤，并呈现正确的视图，但当用户单击“保存并继续”时，将呈现下一步，但实际上没有保存任何内容。

我知道我需要添加一个state_callback，但我不知道如何做到这一点而且Spree文档非常缺乏（大概是因为它很新）

目前我的扩展程序中有以下内容：

模型/礼包/ order_decorator.rb

Spree::Order.class_eval do
  belongs_to :subscription

  accepts_nested_attributes_for :subscription

  # This doesn't appear to be called
  Spree::Order.state_machine.after_transition :from => :subscription,
                                              :do => :valid_subs?

  checkout_flow do
    go_to_state :address
    go_to_state :subscription
    go_to_state :payment, :if => lambda { |order| order.payment_required? }
    go_to_state :confirm, :if => lambda { |order| order.confirmation_required? }
    go_to_state :complete
    remove_transition :from => :delivery, :to => :confirm
  end
end

不完全确定accepts_nested_attributes是必要的，但到目前为止我的开发方法一直是试验和错误，所以它最终停留在那里。

在models / subscription.rb

中

class Subscription < ActiveRecord::Base

  attr_accessible :start_date, :frequency

  belongs_to :user 
  has_many :orders
  has_many :products

  validates :start_date, :frequency, :presence => true

  def schedule
    ...code that returns a list of dates rendered on FE...
  end

  private #----

  ... some methods used in schedule ...

  def valid_subs?
    binding.pry # never called
  end

  def after_subscription
    binding.pry # never called either...
  end
end

视图/礼包/结帐/ _subscription.html.erb

<h1><%= t(:"subscription.title") %></h1>

<div class="columns alpha six" data-hook="subscription_calendar_fieldset_wrapper">
  <fieldset id="subscription_calendar" data-hook>
    <%= form.fields_for :subscription_picker do |subscription_picker| %>
      <legend><%= t(:"subscription.first_delivery") %></legend>
      <%= render :partial => 'subscription/picker' %>
    <% end %>
  </fieldset>
</div>

<div class="columns omega six" data-hook="subscription_dates_fieldset_wrapper">
  <fieldset id="subscription_dates" data-hook>
    <legend align="center"><%= t(:"subscription.next_deliveries") %></legend>
    <div class='dates'></div>
  </fieldset>
</div>

<div class="form-buttons" data-hook="buttons" style='clear:both;'>
  <%= submit_tag t(:save_and_continue), :class => 'continue button primary' %>
</div>

视图/订阅/ _picker.html.erb

<div class='row'>
  <label for="subscription_frequency">Occurs every:</label>
  <% frequency_options = [["2 Weeks", 14], ["3 Weeks", 21], ["Month", 30], ["2 Months", 60], ["3 Months", 90]] %>
  <%= select(:subscription, :frequency, options_for_select(frequency_options, 30), {}) %>
</div>
<div id="start-date-picker" class="calendar"></div>
<%= hidden_field(:subscription, :start_date, {value: (DateTime.now + 14).to_date.iso8601}) %>

... JS that creates the calendar ...

点击“保存并继续”后，我看到发送了以下参数：

{
                  "utf8" => "✓",
               "_method" => "put",
    "authenticity_token" => "...BLAH...",
          "subscription" => {
         "frequency" => "30",
        "start_date" => "2012-11-17"
    },
                "commit" => "Save and Continue",
            "controller" => "spree/checkout",
                "action" => "update",
                 "state" => "subscription"
}

你有两个问题。您的回调未触发，因为对checkout_flow的调用会擦除当前状态机并替换它。在调用checkout_flow后移动此代码：

Spree::Order.state_machine.after_transition :from => :subscription,
                                          :do => :valid_subs?

其次，您的订阅信息未保存，因为参数需要作为订单的一部分传递。 params应该看起来像这样嵌套：

"order" => {    
    "subscription" => {
        "frequency" => "30",
        "start_date" => "2012-11-17"
    }
}

您可以将select和hidden_field的调用附加到相应的“subscription_picker”形式：

<%= subscription_picker.select(:frequency, options_for_select(frequency_options, 30), {}) %>

和

<%= subscription_picker.hidden_field(:start_date, {value: (DateTime.now + 14).to_date.iso8601}) %>

您应该将表单对象传递给partial，作为样式和可理解性的显式参数。

干杯。
