Learnings for Week 27 2010

Late again, I know, but here’s my learnings from a couple weeks ago.

• If you need to use the Rails url helpers within a model or even script/console you just need these two lines:

include ActionController::UrlWriter
default_url_options[:host] = DEFAULT_HOST

• Alternatively within script/console you can use the “‘app’ or ‘helper’ variables to interact with the application”:http://stackoverflow.com/questions/151030/how-do-i-call-controller-view-methods-from-the-console-in-rails

helper.number_to_currency('2342.33')
app.get '/'

• If you want some piece of code to run after each request you can use a ‘config.to_prepare’ block. This might be useful if you have classes reloading in development and want to set settings after they have reloaded.

• Git can sometimes consider text files to be binary if they have Null characters at the end. You can still diff these files with this command:

git diff -a

• Super cool OS X soft phone Telephone

• Facebook applications must be created on a Personal Account, they can not be created with a Business Account.
