# Ensure that you have your iTerm configured to allow the shell to modify the window / tab title.
# In iTerm 3.1.2 this is a checkbox located in Settings > Profile > Terminal: "Terminal may set tab/window title"
# Then, put this in your .bash_profile

# Piece-by-Piece Explanation:
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too

Introduction:

This coding challenge is designed for you to show off your skills to the 3Play Media Developer team. You 
should have the following challenge completed by the time you come in for your in-person interview so we
can take a look at it together. While all of the basic requirements of this project should be met, you're 
encouraged to make this project your own and implement any additional features that you see fit.

Feel free to ask whatever questions, use whatever resources and provide whatever documentation 
you'd like during the completion of this project.

# Foo has_one :bar, Bar belongs_to :foo
# Foo has_one parent_foo and has_many child_foos
# Bar has_one parent_foo through :foo
# Bar has_one parent_bar through :parent_foo
# 
# The parent_bar association incorrectly applies values into the SQL query
# You can see this in the query generated from b1.parent_bar in the code below: notice there are 3 "?"s and 2 node values.
# SELECT  "bars".* FROM "bars" INNER JOIN "foos" ON "bars"."foo_id" = "foos"."id" INNER JOIN "foo_relationships" ON "foos"."id" = "foo_relationships"."parent_foo_id" INNER JOIN "foos" "foos_parent_bar_join" ON "foo_relationships"."child_foo_id" = "foos_parent_bar_join"."id" WHERE "bars"."deleted" = ? AND "foos"."deleted" = ? AND "foos_parent_bar_join"."id" = ? LIMIT 1  [["deleted", "f"], ["id", 2]
#
# This is more noticeable when using MySQL, as it is less forgiving of missing nodes: notice that the id of '2' is being applied to `foos`.`deleted`, and final value for `foos_parent_bar_join`.`id` in the query string is simply missing
