Problem

The go command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.

This assumes your private GitLab is hosted at privategitlab.company.com.

Environment variables

The following environment variables are recommended:

export GO111MODULE=on
export GOPRIVATE=privategitlab.company.com

FROM ruby:2.3.1

# Install dependencies
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs

# Set an environment variable where the Rails app is installed to inside of Docker image:
ENV RAILS_ROOT /var/www/app_name
RUN mkdir -p $RAILS_ROOT

# Set working directory, where the commands will be ran:

Adding an audit log to your Rails app

If you have any sort of administrative interface on your web site, you can easily imagine an intruder gaining access and mucking about. How do you know the extent of the damage? Adding an audit log to your app is one quick solution. An audit log should record a few things:

• controller entry points with parameter values
• permanent information about the user, like user_id
• transient information about the user, like IP and user_agent

Using the Rails framework, this is as simple as adding a before_action to your admin controllers. Here’s a basic version that I’m using in production.

一路过来也部署过3、4个Rails App了，其中也使用过mina等远程部署项目，但每次去部署新的App还是会遇到一些大大小小问题。最近和几个朋友正在做一个应用，在部署的过程中又被自己坑了~所以今天准备总结一下，方便自己未来的部署之路，也方便Rails新手学习使用。

#####环境说明 因为Linux的发型版太多，所以不能一一举例，经过自己的实践体验，发现Ubuntu可以更轻松的部署您的Rails App（个人看法，曾经在Centos下部署，遇到了好多坑）。所以该博文将基于以下的部署环境。

1. 操作系统：Ubuntu14.04
2. Rails：4.2.0
3. Ruby：2.2.1
4. Mysql: 5.6.22
5. Nginx: 1.8.0
6. Puma: 2.11.0

What is Redis?
Redis is an open source, advanced in-memory key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

######1. If you're running OS X, install redis in terminal using Homebrew : brew install redis

######2. Add the redis and hiredis gems to the project's Gemfile (remember to bundle install after you do this) :

Migrating a Rails project from MySQL to PostgreSQL

This brief guide is written from my own experience with migrating a large (~5GB) MySQL database to PostgreSQL for a Rails project.

No warranties, guarantees, support etc. Use at your own risk and, as always, ENSURE YOU MAKE BACKUPS FIRST!

I chose [pgloader][1] because it's extremely fast. YMMV.

1. Replace mysql2 gem with pg in Gemfile.
2. Update config/database.yml for PostgreSQL. I used [Rails' template][2] as a starting point.

# This concern enables namespaces in Pundit. In order to use it, put this
# module into the `app/controllers/concerns` folder of your project and then
# include the module into the controller you want to namespace the policies in
# after the include of Pundit.
#
# To secify the namespace to use, overwrite the `pundit_namespace` method on
# your controller then.
