我正在构建一个我想发布的应用程序,我将用Python编写应用程序.我不想锁定任何特定数据库sql/nosql到我的应用程序的使用.如何设计应用程序或模型层以不强制执行SQL/NOSQL方式来存储数据.
是否存在兼容两种存储的ORM？我找不到一个.通常情况下我会使用sqlalchemy来确保人们可以使用MySQL/PostgreSQL/MSSQL /等,但是将NOSQL添加到图片中似乎比我最初想象的要复杂得多.
我有一些要求,如:
如果您对我如何构建这些要求有所了解,我将非常感谢您的帮助.是否可以创建这样的结构:
+-----+
+ app +
+-----+
|
+-------------+
+ Data Access +
+-------------+
|
+-----------+
+ SQL/NOSQL +
+-----------+
谢谢
我正在尝试将部署设置为pypi,但在构建测试后出现错误.我的travis-ci文件在这里:
https://github.com/EnlightNS/enlightns-cli/blob/master/.travis.yml
我使用了setup pypi命令行生成了我.travis.yml文件中的部分.
travis setup pypi
构建失败在这里:
https://travis-ci.org/EnlightNS/enlightns-cli/jobs/78112477
错误就在这里:
Fetching: dpl-1.7.21.gem (100%)
Successfully installed dpl-1.7.21
1 gem installed
invalid option "--password="
failed to deploy
我无法弄清楚我做错了什么.
问候
I am on Ubuntu 14.04 and I installed rabbitmq. As I was reading through the configuration documentation, I wanted to create my own rabbitmq.config file in /etc/rabbitmq/rabbitmq.config, so I searched for an example of a configuration file which I found under /usr/share/doc/rabbitmq-server/rabbitmq.config.example.gz.
I unzipped it in /etc/rabbitmq/rabbitmq.config and started to uncomment many options. Once I tried to restart rabbitmq through sudo service rabbitmq-server restart it failed. I looked in the logs and I found the following error:
==> …我不明白或看到我做错了什么,但似乎我无法让我的ansible playbook在ubuntu服务器上启动rng-tools服务.
environment:
remote server (configured): Ubuntu 14.04.1 LTS
server with playbook: Debian GNU/Linux 7.6 (wheezy)
> apt-cache policy ansible
ansible:
Installed: 1.7-0.git201406241728~unstable
Candidate: 1.7-0.git201406241728~unstable
Version table:
*** 1.7-0.git201406241728~unstable 0
100 /var/lib/dpkg/status
我的文件夹结构如下:
tasks/main.yml
tasks/packages.yml that is included from the main.yml file
handlers/main.yml
files/rng-tools
我正在使用我的playbook安装包rng-tools,并在执行后安装.
- name: install common packages
apt: name={{ item }} state=present
with_items:
- gnupg
- rng-tools
- reprepro
- dpkg-sig
- nginx
是的我正在安装多个包,但它们都已正确安装.
安装完成后,我使用以下方法复制/ etc/default/rng-tools文件:
- name: copy urandom default conf file
copy: src="rng-tools" dest="/etc/default/rng-tools"
notify: …首先要提到的是我的代码在IE8和谷歌浏览器中运行.只有在Firefox下,我才遇到问题,在Ubuntu和Win XP下测试它同样的问题.
我正在尝试在刷新页面时显示ajaxloader gif图像.在一开始我使用jquery .ready()函数来隐藏将显示图像的div#refresh.当我们点击刷新链接时,我会显示div#refresh.我的问题是ajaxloader.gif没有变得像它应该成为一个修复图像.但提到它在chrome和IE下工作.
知道为什么吗？
HTML:
<div id="refreshing">Refreshing</div>
<a href="javascript: refreshPage();">Refresh</a>
CSS:
#refreshing {
font: 14px Verdana,Arial;
color: #00264b;
background: url("/med/base/img/ajax-loader-blue.gif") center no-repeat;
}
JavaScript的:
$(document).ready(
function() {
// hide the ajax loader
$("#refreshing").hide();
}
);
function refreshPage() {
$("input").attr("disabled", "disabled");
$("select").attr("disabled", "disabled");
$("img").attr("onclick", "");
$("a").attr("href", "#");
window.location.href = window.location.href;
$("#refreshing").toggle();
}
还有一件事是firefox配置image.animation_mode设置为normal.此外,如果我看到萤火虫,图像是动画的.
谢谢大家.
我正在尝试通过企业Active Directory服务器对我的用户进行身份验证.我无法正确配置它,我知道LDAP工作我有一个MediaWiki配置并在Active Directory服务器上进行身份验证.
