我想$data从命名的控制器传递poll 到results_view但是我得到一个未定义的变量错误.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Poll extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->database();
$this->load->helper('form');
}
public function index()
{
$this->load->view('poll_view',$data);
}
public function vote()
{
echo "Voting Successfull";
$this->db->insert('votes',$_POST);
}
public function results()
{
echo "These are the results";
//$query = $this->db->get('votes');
$data = "hello";
$this->load->view('results_view', $data);
}
}
Results_view.php
<html>
<?php echo $data; ?>

我有一个Zebra GK420d通过CUPS连接到OS X. 但是,当我发送用ZPL或EPL编写的文件时,它们只以纯文本形式打印.
我需要在打印机上更改模式吗？
我正在使用Oauth2 Gem连接到服务。
我可以收到授权代码，但是当我使用该代码检索用户令牌时，会得到Faraday :: ConnectionFailed（到达文件末尾）：
其他大多数问题都归因于过时的证书。但是，当我部署到Heroku时，此错误仍然存在。
client = OAuth2::Client.new(client_id, client_secret, :site => 'https://auth.mxit.com', :authorize_url => '/authorize', :token_url => '/token')
auth_code1 = client.auth_code.authorize_url(:redirect_uri => root_url+'oauth2/callback', :scope => 'message/send')
auth_code1 =params[:code]
base_code = Base64.encode64(client_id+' : '+client_secret)
token = client.auth_code.get_token(auth_code1, :redirect_uri => root_url+'oauth2', :grant_type =>'authorization_code', :headers => {'Content-Type' => 'application/x-www-form-urlencoded','Authorization' => 'Basic'+base_code })
我在 AWS Elastic Beanstalk 上使用 Rails 5.2.3 运行 Sidekiq。按照我设置的Sidekiq wiki中的说明进行操作initializers/sidekiq.rb：
Sidekiq.configure_server do |config|
config.logger.level = Logger::WARN
end
这在开发环境中有效，但在生产环境中 Sidekiq 仍在调试级别生成日志。Rails 生产记录器级别设置为config.log_level = :warn

我正试图让上帝启动我的resque队列.但是,当我运行god load config/resque.god它返回The server is not available (or you do not have permissions to access it)
这是我的resque.god文件:
rails_env = ENV['RAILS_ENV'] || "production"
rails_root = ENV['RAILS_ROOT'] || "/Users/andrewlynch/sites/wellness/wellbot"
God.watch do |w|
w.name = "resque-worker"
w.group = "resque"
w.interval = 60.seconds
w.dir = "#{rails_root}"
w.start = "RAILS_ENV=development QUEUE=* rake resque:work"
w.start_grace = 30.seconds
end
我正在尝试使用内置于Graphite中的AMQP将RabbitMQ连接到Graphite.但是当我取消注释carbon.conf我得到的设置时:

from …我正在尝试将Dashing部署到Heroku.Everthing在localhost上完美运行.使用github页面提供的说明进行部署
它似乎与backports宝石有关.
