为什么在我部署的代码上单击特定 link 时会出现 500 错误？

Question

当我在远程服务器上的运行应用程序上访问特定端点时，我收到 500 内部错误。然而，代码在我的本地 system/server.

上运行良好

代码：

order_controller.rb

module Admin
  module Statistic
    class OrdersController < BaseController
      def show
        @orders_grid = ::Statistic::OrdersGrid.new(params[:statistic_orders_grid])
        @assets = @orders_grid.assets
        @paginated_assets = @assets.page(params[:page]).per(20)

        fee_sums_per_currency = {}
        @assets.each do |order|
          fee_currency = order.get_order_fee_currency
          unless fee_sums_per_currency.key?(fee_currency)
            fee_sums_per_currency[fee_currency] = 0
          end
          fee_sums_per_currency[fee_currency] += order.fee
        end
        fee_summary = []
        fee_sums_per_currency.each do |currency, fee_sum|
          fee_summary << "#{ currency } #{ fee_sum }"
        end

        @summary = {
          :count => @assets.length,
          :fee_summary => fee_summary.join(",  ")
        }
        @order_reset_button = true
      end
    end
  end
end

导航栏 基于 cancancan

- if can? :menu, Trade
            li.dropdown class = check_active('withdraws')
              = link_to 'javascript:;', class: 'dropdown-toggle', 'data-toggle' => 'dropdown' do
                span = t('admin_header.trades')
                span.caret
              ul.dropdown-menu
                - if can? :manage, Order
                  li class = check_active('orders')
                    = link_to t(".menus.items.operating.orders"), admin_statistic_orders_path

ability.rb

module Admin
  class Ability
    include CanCan::Ability

    def initialize(user)
      return unless user.admin?

      can :read, Order
      can :read, Trade
      can :read, Proof
      can :update, Proof
      can :manage, Document
      can :manage, Member
      can :manage, Ticket
      can :manage, IdDocument
      can :manage, TwoFactor
      can :manage, Coupon
      can :manage, Order
      can :manage, Trade
      can :manage, Revenue

      can :menu, Deposit
      can :menu, Trade
    end
  end
end

config/routes/admin.rb

namespace :admin do
namespace :statistic do
    resource :orders, :only => :show
    resource :trades, :only => :show
  end
end

我已经检查过但不知道在开发服务器上而不是在远程服务器上工作遗漏了什么。

Answer 1

所以我发现问题来自ability.rb。 Order 未在 ability.rb 中定义，我引用为 :menu。

所以我不得不在ability.rb

中定义它

module Admin
  class Ability
    include CanCan::Ability

    def initialize(user)
      return unless user.admin?

      can :read, Order
      can :read, Trade
      can :read, Proof
      can :update, Proof
      can :manage, Document
      can :manage, Member
      can :manage, Ticket
      can :manage, IdDocument
      can :manage, TwoFactor
      can :manage, Coupon
      can :manage, Order
      can :manage, Trade
      can :manage, Revenue

      can :menu, Deposit
      can :menu, Trade
      can :menu, Order # So I added this for `Order` to be references as `:menu` by admin.
    end
  end
end

然后在由 Cancancan 驱动的 Navbar 中，我将 Order 添加到 if 语句

- if can? :menu, Trade || Order # So I added this as well.
            li.dropdown class = check_active('withdraws')
              = link_to 'javascript:;', class: 'dropdown-toggle', 'data-toggle' => 'dropdown' do
                span = t('admin_header.trades')
                span.caret
              ul.dropdown-menu
                - if can? :manage, Order
                  li class = check_active('orders')
                    = link_to t(".menus.items.operating.orders"), admin_statistic_orders_path

为什么在我部署的代码上单击特定 link 时会出现 500 错误？

Why do I get 500 Error upon clicking a particular link on my deployed code?
