Question

我目前正在开发一个预订空间在线申请项目。用户可以进行查询，空间的所有者可以接受/拒绝甚至在消息线程中提出反要约。

我们的应用程序似乎更新了术语(self.hire_to.to_date - self.hire_from.to_date).to_i：

class EnquiryOffer < ActiveRecord::Base

  belongs_to :enquiry
  has_one :enquiry_state

  validates_presence_of :hire_from, :allow_blank => false
  validates_presence_of :hire_to, :allow_blank => false

  before_save do
    EnquiryOffer.where(enquiry_id: self.enquiry_id).update_all(:state => 'inactive')
  end

  def term
    Rails.logger.info "#### Active offer term #{(self.hire_to.to_date - self.hire_from.to_date).to_i}"
    (self.hire_to.to_date - self.hire_from.to_date).to_i
  end
end

什么似乎是一个问题，当提出还价时，价格不会更新。我猜测如果我在此模型中包含价格，它应该在新的柜台报价时更新。

我是对的吗？（可能不是！）

更新：

查询模型包含这些代码片段，可以让您更好地了解：

  def offer_price
    puts "price #{self.property.price}"
    puts "term #{self.active_offer.term}"
    self.property.price * self.active_offer.term
  end

def make_offer(conversation_id, offer_id)
    states.create! state: "offer_made", conversation_id: conversation_id, enquiry_offer_id: offer_id, receiver_id: self.user_id if open? || offer_rejected? || enquiry_rejected?
  end

  def active_offer
    Rails.logger.info "ACTIVE OFFER #{self.enquiry_offers.where("state = 'active'").first.inspect}"
    self.enquiry_offers.where("state = 'active'").first
  end

          html += action_view.render(:partial => 'messages/message_default', :locals => {:@message => "<h2><i class='glyphicon glyphicon-transfer'></i> You suggested a counter offer</h2> From <b>#{s.enquiry_offer.hire_from.strftime("%d/%m/%y")}</b> to <b>#{s.enquiry_offer.hire_to.strftime("%d/%m/%y")}</b> for <b>&pound;#{self.price.round}</b> with a fee of <b>&pound;#{self.commission(current_user)}</b>.", :@state => s, :@conversation => conversation, :@enquiry => self, :@url => Rails.application.routes.url_helpers.accept_offer_enquiries_path})
        elsif s.state == Enquiry::STATES[4]
          action_view = ActionView::Base.new(Rails.configuration.paths["app/views"])
          action_view.class_eval do 
            include Rails.application.routes.url_helpers
            include ApplicationHelper
            def protect_against_forgery?
              false
            end
          end

关键问题是，在提出反要约时，价格与开启询价的初始报价保持一致。
