Review Summary
Your implementation violates two explicit checklist requirements that must be fixed. First, all ForeignKey fields are missing related_name (checklist item #3) in db/models.py, main.py, and migration files — add related_name='skills' to Skill.race, related_name='players' to Player.race, and related_name='players' to Player.guild. Second, unsafe direct dictionary access [] is used instead of .get() method (checklist item #5) throughout main.py and other files — replace all players_data[player]["key"] with players_data[player].get("key") to prevent KeyError. Additionally, there's a bug in main.py guild handling: when guild_data is None, the try/except catches TypeError but guild_obj remains undefined, causing a NameError on subsequent line. Use guild_data = players_data[player].get("guild") with a conditional check instead of the fragile try/except approach.

The guild handling logic is problematic. If players_data[player].get("guild") returns None, the code catches TypeError but guild_obj remains undefined, causing a NameError on line 33. Replace the try/except block with proper conditional logic: guild_data = players_data[player].get("guild") followed by if guild_data: check.

This violates task requirements. When guild is deleted, player should NOT be deleted. Use on_delete=models.SET_NULL instead of DO_NOTHING. The 0005 migration eventually fixes this, but the intermediate migration state is incorrect.
