Ruby on rails 获取404找不到默认错误页“；活动记录：：RecordNotFound"；当我有一个自定义页面的时候

我有一个404&500状态代码的自定义错误页面，当我放置localhost:3000/something.html时，它可以正常工作。但当我将localhost:3000/controller/element\u放在一个模型中时，它就不起作用了

routes.rb：

if Rails.env.production? then
  unless Rails.application.config.consider_all_requests_local
    get '*not_found', to: 'errors#error_404'
    get '*internal_server_error', to: 'errors#error_500'
  end
else
  unless
    get '*not_found', to: 'errors#error_404'
    get '*internal_server_error', to: 'errors#error_500'
  end
end

错误控制器：

def error_404
    render_error 404
end

def error_500
    render_error 500
end

private
   def render_error(status)
       respond_to do |format|
           format.html { render 'error_' + status.to_s() + '.html', :status => status, :layout => 'errors'}
           format.all { render :nothing => true, :status => status }
   end
end

rescue_from ActiveRecord::RecordNotFound do |exception|
  render_error 404
end


def render_error(status)
  respond_to do |format|
    format.html { render 'error_' + status.to_s() + '.html', :status => status, :layout => 'errors'}
    format.all { render :nothing => true, :status => status }
  end
end

您必须将其放入应用程序控制器：

def error_404
    render_error 404
end

def error_500
    render_error 500
end

private
   def render_error(status)
       respond_to do |format|
           format.html { render 'error_' + status.to_s() + '.html', :status => status, :layout => 'errors'}
           format.all { render :nothing => true, :status => status }
   end
end

rescue_from ActiveRecord::RecordNotFound do |exception|
  render_error 404
end


def render_error(status)
  respond_to do |format|
    format.html { render 'error_' + status.to_s() + '.html', :status => status, :layout => 'errors'}
    format.all { render :nothing => true, :status => status }
  end
end

实际上，您的ErrorController将由路由触发，但您必须为异常添加逻辑
