Coder
Hi all,
I'm a super new coder and I've set myself a project of building a small text-based game played in the browser to learn skills. I've built some basic features of my game and one of these is a gym, which I've been struggling with for a few days now without success.
Essentially, as you will see from my code, I am attempting to set a system whereby a player can train a stat once every 30 minutes. However, no matter what I do, I can't seem to enforce the cooldown. I'm using a database column last_train_time which I have verified is being correctly updated upon a train, as is the stat, however, I cannot seem to force the cooldown - a player is able to bypass the cooldown by just refreshing and resubmitting, or is able to train again without my error message showing and completely bypassing the cooldown.
I've tried multiple versions of code and have recoded the page three times so far to no avail, I just cannot fix this problem. I've read the guidance about not posting a wall of code, but seeing as I have no idea which part I am making an error in, here is the full 130 or so line code for the file - I'd appreciate any help!
