In addition to the charts that follow, you might want to consider the Frequently Asked Questions section for a selection of common questions about MongoDB.

Executables¶

The following table presents the MySQL/Oracle executables and the corresponding MongoDB executables.

Using the graph to control unique id generation

Introduction

This gist was prompted by Nigel Small’s tweet of a query to generate a unique id for a node (and is posted here with his agreement). It inspired me to think about how it could be used in a full example, unrestricted by Twitter’s 140 characters. I have also looked at how we could generate different sets of unique ids for different labels.

Auto-incrementing #Neo4j counter MERGE (x:Counter {name:'foo'}) ON CREATE SET x.count = 0 ON MATCH SET x.count = x.count + 1 RETURN x.count

PSQL

Magic words:

psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*

Welcome to the first episode in a series of short screencasts for the Ruby neo4j gem. Each episode will describe a different aspect of the gem. In this first episode, we will start by discussing how to set up a new Ruby on Rails app using Neo4j. The neo4j gem is not Rails specific so you can use other frameworks like Sinatra or Lotus, but because of the popularity of Ruby on Rails we will be using it for this screencast series.

In this series we’re going to create an application to host digital assets which we’ll call "asset_portal". To create your Rails app you can run a rails new command as usual. To use Neo4j instead of ActiveRecord you can give arguments which will set up a new Rails app using Neo4j models.

rails new asset_portal -m http://neo4jrb.io/neo4j/neo4j.rb -O

The dash-m argument runs a script from the neo4j gem project and the dash-capital-O argument says to exclude ActiveRecord. There aren’t any restrictions on using Neo4j with other ORMs like ActiveRecord, but you will need to conf

Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

Create database

rake db:create

Create database table

This will creates a migration file in /db/migrate without table definition.

rails g migration create_<TABLE>

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
