Here's an example of a few different ways to call a method on a Ruby object.

If you're a beginner, try running the code above to watch it in action.

If you're not a beginner, go ahead and tear me a new one for whichever techniques I forgot ;)

Surround a heredoc with quotes and you can continue the code on the same line:

    render :status => 404, :text => <<-'EOH' and return unless setup
        article not found<br/>
        I, as a server, have failed<br/>
        https?
        EOH

Quotes also give you more freedom/creativity with the terminal ID:

1. Create a text backup of your data form the live server.  This will ask for a password.

    mysqldump -u your_user -p your_redmine_database > backup_sql_file.sql

2. Transfer the backup_sql_file.sql to your new server.

3. Once there, drop the existing database on the new server and import your database to the empty database on the new server.

    !!!! Triple check this is on the new server and not your live one!!!!

# Tasks can fall through the gaps when matching on '='
# e.g. for a task where due_at = 2009-09-16 23:00:00, and where Time.now = 2009-09-16,
#      it would not match due_today or due_tomorrow, hence would not appear in Fat Free.
named_scope :due_today,     lambda { { :conditions => [ "due_at = ?", Time.zone.now.midnight.utc ], :order => "id DESC" } }
named_scope :due_tomorrow,  lambda { { :conditions => [ "due_at = ?", Time.zone.now.midnight.tomorrow.utc ], :order => "id DESC" } }

# By specifying a range of dates, tasks would always match with one of the bucket dates.

    { :conditions => [ "due_at >= ? AND due_at < ?", Time.zone.now.midnight.utc, Time.zone.now.midnight.tomorrow.utc ], :order => "id DESC" }
