Calculations By Time Range¶ ↑

Add new methods for ActiveRecord to get agregate values by time range.

Install the gem from rubyforge:

sudo gem install calculations_by_time_range

Now just set it as a dependency in your project and you are ready to go.

You can also install this as a plugin:

script/plugin install git://github.com/miry/calculations_by_time_range.git

See below for usage examples.

# We have the following model
User(id: integer, created_at: datetime, updated_at: datetime, username: string, age: integer)

# CalculationsByTimeRange gives you a bunch of named scopes for free:
User.counts_by_day
User.counts_by(:day)
User.counts_by(:day, '*', 'updated_at')
User.sums_by(:week, 'age')

User.created_at_gt(1.day.ago).counts_by_hours

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
