These are some of my (Ryan Bates) favorite gems to use for various tasks:
| require File.expand_path(File.dirname(__FILE__) + '/../test_helper') | |
| class BuildStatusTest < ActiveSupport::TestCase | |
| test "remove the old statii" do | |
| assert_equal 2, BuildStatus.count | |
| BuildStatus.expire_old | |
| statii = BuildStatus.all | |
| assert_equal 1, statii.size | |
| assert statii[0].updated_at >= 30.days.ago | |
| end |
The new rake task assets:clean removes precompiled assets. [fxn]
Application and plugin generation run bundle install unless --skip-gemfile or --skip-bundle. [fxn]

| literally always have to look up the meaning of :limit in migrations when it comes to integer values. Here's an overview. Now let's memorise it (oh, this works for MySQL, other databases may work differently): | |
| :limit Numeric Type Column Size Max value | |
| 1 tinyint 1 byte 127 | |
| 2 smallint 2 bytes 32767 | |
| 3 mediumint 3 byte 8388607 | |
| nil, 4, 11 int(11) 4 byte 2147483647 | |
| 5..8 bigint 8 byte 9223372036854775807 | |
| Note: by default MySQL uses signed integers and Rails has no way (that I know of) to change this behaviour. Subsequently, the max. values noted are for signed integers. |

| end | |
| end | |
| logfile = File.open("#{Rails.root}/log/custom.log", 'a') # create log file | |
