itskingori / disable_db_tasks_on_production.rake
Created December 17, 2014 06:54
Disable dangerous rake tasks in production. It's a matter of adding a prerequisite to those dangerous tasks, that checks if they are being run in production, and exit accordingly. Also added is a flag to override this safeguard, together with some code to backup the DB.
# Could be in lib/tasks/disable_db_tasks_on_production.rake
# See original http://www.developingandstuff.com/2014/06/disable-dangerous-rake-tasks-in.html
DISABLED_TASKS = [
'db:drop',
'db:migrate:reset',
'db:schema:load',

If you have a long running or complicated task that you want to distribute across multiple processes, you can break it into small segments and use DelayedJob to distribute the workload. You can send a lot of email quickly using the methodology below (and a lot of DJ workers).
User.find_in_batches do |user_batch|
do_something_complicated(user_batch)
end
def do_something_complicated(users)
users.each do
user.something_complicated

itskingori / annotateit-ruby-jwt.md
Last active December 24, 2017 08:01
Example to show how to integrate a site with AnnotatorJS with AnnotateIt.org Store. Includes the Javascript part as well as some server side token generators : one in Ruby and the other in Python.

Replace the Auth options hash value having token: <TOKEN_FOR_TESTING_THAT_LASTS_FOR_A_DAY> with an actual token. This token can be generated by the server side scripts and copied in. It supercedes the tokenUrl: if set.

Just to be 100% sure, feel free to verify the validity of the JSON Web Token generated using jwt.io, JWT debugger. Oh, and the TTL is set to 86400 which is a day. Enough time to generate a token and play around with it.

Ps: If there are any amendments that I can make to improve clarity or fix issues, feel free to leave a comment below. I'll get a notification and act on it as soon as I can.

Ps 2: I was experiencing an issue with CORS and so I submitted the issue (and this code) to the annotator-dev mailing list. Check the July 2014 archives for an email with the subject ... '[annotator-dev] Integrating Site With AnnotateIt Store'.
