创建操作后更新数据库不起作用

set_bonus(member_id, cookie)方法不起作用。我正在尝试更新与self.set_signup_attribution(member_id, cookie, origin)返回相同的模型。

该new_has_value变量返回{"currency"=>"usd", "type"=>"flat", "amount"=>1000}

模型.rb

# THIS METHOD WORKS
def self.set_signup_attribution(member_id, cookie, origin)
  return unless cookie.present?
  tracking_code = cookie
  attribution_channel = AttributionChannel.find_by tracking_code: tracking_code
  associated_member_record = Member.find member_id
  if attribution_channel.present?
    Attribution.create!({
      event: Attribution::SIGN_UP,
      attribution_channel: attribution_channel,
      associated: associated_member_record,
      extra: origin
    })
    set_bonus(member_id, cookie)
  else
    Rails.logger.info "Unknown Attribution Channel for tracking code: '#{ tracking_code }'"
  end
end


# THIS METHOD DOES NOT WORK. UPDATES THE DATABASE.
def self.set_bonus(member_id, cookie)
  epoch = Member.find_by(id: member_id).attribution_epoch
  attribution_code = AttributionChannel.find_by(tracking_code: cookie)
  duration_value = attribution_code.attribution_duration.downcase.split(' ')
  duration = duration_value.first.to_i.send(duration_value.last)
  return if cookie.present? && epoch.present?
  current_time = Time.now
  if attribution_code.bonus_config.present?
    if (current_time - epoch).to_i < duration
      hash_value = attribution_code.bonus_config
      new_hash_value = hash_value.assoc("sign_up")[1]
      value = Attribution.where(attribution_channel_id: attribution_code)
      if new_hash_value["type"] == "flat"
        value.update_all(
          bonus_amount: new_hash_value["amount"],
          bonus_currency: new_hash_value["currency"]
        )
      elsif new_hash_value["type"] == "percentage"
        value.update_all(
          bonus_amount: new_hash_value["amount"],
          bonus_currency: new_hash_value["currency"]
        )
      else
        {
          bonus_amount: "Doesn't exist",
          bonus_currency: "Doesn't exist"
        }
      end
    else
      "Do nothing"
    end
  else
    "Do nothing"
  end
  #cookie = nil
  binding.pry
end

控制器文件

def index
  unless session[:just_signed_up]
    redirect_back_or_settings_page
  end
  Attribution.set_signup_attribution(current_user, cookies[:visit_attr], request.referer)
  Attribution.set_bonus(current_user, cookies[:visit_attr])
  session[:just_signed_up] = false
  @email = current_user.email
end

我该怎么做？这就是我已经尝试过但不起作用的方法。我可以将set_bonus方法合并到set_signup_attribution方法或其他什么吗？

任何帮助将不胜感激。

所以进一步钻研：

我合并set_bonus与set_signup_attribution和这两个字段（bonus_amount和bonus_currency），其set_bonus方法是应该更新返回nil：

Attribution.create!(
  {
    event: Attribution::SIGN_UP,
    attribution_channel: attribution_channel,
    associated: associated_member_record,
    extra: origin
  }.merge(self.set_bonus(member_id, cookie).to_h)
)

使用后此钻头binding.pry上set_bonus的方法，我想通了，它的工作，但它的返回nil，我不知道为什么。可能是因为member_id在模型中不可用还是什么？
