PHP

I've dabbled with PHP in college, using template engines like smarty for college projects. Recently I've been heavily involved in setting up a Drupal based site, which has meant getting back into PHP to make various changes to the source to suit our needs.

Log to file

Had to log to file with PHP, used function below.

 1 <?php
 2 function logToFile($msg) { 
 3         // open file
 4         $filename = 'payments.log';
 5         $fd = fopen($filename, "a");
 6         // append date/time to message
 7         $str = "[" . date("Y/m/d h:i:s", mktime()) . "] " . $msg; 
 8         // write string
 9         fwrite($fd, $str . "\n");
10         // close file
11         fclose($fd);
12 }
13 ?>

BDD - Rails 3, AutoTest, RSpec and Growl

Sat, 30 Apr 2011 12:09:05 GMT

Ruby (on Rails)

I've been using Ruby on Rails for a few years, in my spare time, and hope to keep working with it whenever the opportunity arises. A couple of college friends and I created hospitalpages.ie which is was developed using Ruby on Rails, Git and Capistrano for deployment. I also hope to dabble more in pure Ruby scripting, to date I've used it for automating data insertion with MySQL and some file parsing.

BDD - Rails 3, AutoTest, RSpec and Growl

RSpec and AutoTest with Growl notifications set up for Ubuntu 10.10. Here's what worked for me. This is a rapid post to help me when I need to do this in the future. There is a more comprehensive guide for more platforms here http://ph7spot.com/musings/getting-started-with-autotest

lines that start with t: are to be run in terminal

t: sudo gem install rspec

t: sudo gem install rspec-rails

t: sudo gem install autotest

t: sudo gem install autotest-rails

t: sudo gem install autotest-growl

t: sudo gem install autotest-notification

t: sudo gem install test_notifier

t: sudo apt-get install libnotify-bin

t: find ~/ -iname '.autotest'

t: sudo gedit

Add following lines .autotest file:

require "autotest/growl"

require "test_notifier/autotest"

t: an-install

t: rails new some-app-name>

t: rails scaffold some-name model-details

t: rake db:migrate (create the database before running this)

In application.rb of the rails app add the following lines:

1 config.generators do |g|</p>
2    g.test_framework :rspec</p>
3 end

Add the following to Gemfile of rails application

gem 'rspec'

gem 'rspec-rails'

t: rails generate rspec:install

t: rake -T spec

rake -t spec should show you the rspec rake tasks that are now available.

t: rake spec (this creates the test database entries required for you tests)

Start autotest under your rails application by typing autotest

If things have worked you should get a window pop up with a green smiley face, assuming you have some tests that pass, otherwise you'll see a red sad face.

Get value from checkbox in rails (2.0.4)

Get value from checkbox in rails (2.0.4)

With below checkbox, access the value in controller with something like :params[checkbox_name], e.g. if (:params[checkbox_name] == 'selected') # do something..

1 <%= check_box_tag 'checkbox_name', 'selected' %>

becomes:

1 <input type="checkbox" value="selected" name="checkbox_name" id="checkbox_name">

Note if the checkbox is not selected you won't be able to access the value, it is only accessible if the checkbox is selected.

RubyMine setup and launch application as root

Wed, 23 Feb 2011 18:20:29 GMT

Ubuntu

I've been running Ubuntu since early 2007. Had a few teething problems with sound cards at the start but worked around them by using OSS. Happily the necessary drivers were updated in the latest releases. Below are tricks picked up over the years of using Ubuntu.

RubyMine setup and launch application as root

I have openjdk installed as well as sun jdk, so when I ran rubymine I was getting a warning message about using openjdk. So to fix this the below line was added to the rubymine.sh file:

export JDK_HOME=/usr/lib/jvm/java-6-sun-1.6.0.22

Next I wanted to set up a launcher for RubyMine, here's what I did.

Right click and select "Add to Panel", select "Custom Application Launcher", select "Add". For Type select "Application in Terminal", choose a name, the command should start with gksudo followed by the location of rubymine.sh. So full command is something like:

gksudo /path/to/rubymine.sh

Public Keys accessing github gives Agent admitted failure to sign using the key.

Got this error recently when trying to connect to github, having not connected for awhile:

Agent admitted failure to sign using the key. Permission denied (publickey).

To workaround run: sudo export SSH_AUTH_SOCK=0
