Q:

Why is there no tasks folder in active record gem

when I read through active record source on github repo, I can find active_record/tasks folder there but in the gem I install through gem install, that folder is missing. why?

A:

That's because it's new in Rails 4 and so only on master branch, if you have a look at the tag for the version you installed (e.g. here for 3.2.9), you'll see that the folder is not there either.
