Auto-Generating Unique Usernames in Supabase Trigger Function Not Working
Hello everyone,
I'm working on a project using Supabase and I've run into an issue with a trigger function designed to auto-generate unique usernames for new users. I would greatly appreciate any insights or assistance in resolving this problem.
Here's the situation:
Goal: Automatically create a unique username in the format "player#<number>" for each new user who signs up.
Problem: The trigger function I wrote isn't generating unique usernames as intended. It seems the logic meant to increment the count for each new user is not functioning correctly.
Current Approach:

Here's the situation:
Goal: Automatically create a unique username in the format "player#<number>" for each new user who signs up.
Problem: The trigger function I wrote isn't generating unique usernames as intended. It seems the logic meant to increment the count for each new user is not functioning correctly.
Current Approach:
create function public.handle_new_user () returns trigger as $$
declare
row_count int;
row_count_text text;
begin
-- get the current row count
-- select count(*) into row_count from profiles;
-- Increment the row count for the new username
row_count := row_count + 1;
row_count_text := row_count::text;
insert into public.profiles (id, username)
values (new.id, ('player#' || row_count_text));
return new;
end;
$$ language plpgsql security definer;Questions:
- How can I modify this function to ensure each username is unique and follows the desired format?
- Are there better approaches or best practices for achieving this in a Supabase environment?
- How can I debug this to see what's going wrong during the trigger execution?
Any advice, code snippets, or resources would be incredibly helpful. I'm relatively new to using Supabase and triggers, so detailed explanations would be greatly appreciated.
