Let's say you have a model, with an files attached, using Paperclip. You have a couple millions of those files and you're not sure that every one of them (and all its thumbnails) are still used by a database record.
You could use this rake task to recursively scan all the directories and check if the files need to be kept or destroyed.
In this example, the model is called Picture, the attachment is image and the path is partitioned like images/001/412/497/actual_file.jpg
The task is going down the path. Each time the path ends with 3 triplets of digits ("001/412/497" for example) it looks for a record with the ID 1412497. If such a record doesn't exist, the whole directory is moved to a parallel images_deleted directory. At the end you can delete the files if you like, or move them to an archive location.
You can use the "dry run" mode : to print which files would be removed
| #!/usr/bin/env ruby | |
| require 'rubygems' | |
| require 'solareventcalculator' | |
| solar = SolarEventCalculator.new(Date.today, BigDecimal.new('51.563'), BigDecimal.new('-0.499')) | |
| puts "Sunrise: #{solar.compute_utc_civil_sunrise.getlocal}" | |
| puts "Sunset: #{solar.compute_utc_civil_sunset.getlocal}" |
Howdy howdy, NSHipsters!
If you alloc init an NSCalendar, you'll notice that New Year's Eve falls on a Monday this year, a.k.a. "the day NSHipster is published every week". What fun!
So in celebration of the upcoming year++, I thought it'd be fun to compile a list of some of your favorite tips and tricks of the trade. Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!
Here are a few examples of the kind of things I'd like to see:
| <!DOCTYPE html> | |
| <head> | |
| <title>Build report</title> | |
| <style type="text/css"> | |
| body | |
| { | |
| margin: 0px; | |
| padding: 15px; | |
| } |
The philosophy behind Documentation-Driven Development is a simple: from the perspective of a user, if a feature is not documented, then it doesn't exist, and if a feature is documented incorrectly, then it's broken.
