Calculations By Time Range
Add new methods for ActiveRecord to get agregate values by time range.
Install & use
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')
Examples with Searchlogic and scopes
Note on Patches/Pull Requests
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.
