# FUNDRAISER VARIABLES AND CONSTANTS GUIDE
## From Local Context
* datetime_now: Current DateTime in UTC
* sitefundgoal: The current FundraisingGoal. Attributes:
* fundraiser_goal_amount: The amount being matched
* fundraiser_so_far_amount: The amount contributed so far
* fundraiser_donation_count: The number of people who have contributed so far
* fundraiser_donation_count_disclose_threshold: The number of new Sustainers that can be double-matched this fundraiser.
(No, this name makes no sense. We're repurposing an existing model field for this new reason.)
* sitefundgoal_endtime: DateTime when sitefundgoal ends.
## Local convenience variables
* sitefundgoal_timeleft: TimeDelta for how much time remains in the current fundraiser
* this_match_goal: The amount being matched
* this_match_so_far: The amount contributed so far
* this_match_remaining: this_match_goal - this_match_so_far
* this_match_exceeded: this_match_so_far - this_match_goal
