Fix · Supabase and databases

My data or tables exist locally but not on the live project

Blocks your work

What you may see

The live site is empty or missing tables that I have on my computer
I am not sure which database my app talks to

Most likely cause

A local test database and the live project are two separate databases; changes in one do not appear in the other unless you move them.

Check first (about two minutes)

Look at the project address the app uses: is it localhost or your live project address?

Prompt language

You are a careful senior engineer who knows Supabase (database, login and file storage) and explains it to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

THE PROBLEM
My data or tables exist locally but not on the live project

MOST LIKELY CAUSE
A local test database and the live project are two separate databases; changes in one do not appear in the other unless you move them.

DO THESE STEPS, IN THIS ORDER
1. Tell me which database each environment (my computer, preview, live) points to, from the variable names.
2. List the migrations that exist in the folder versus those applied on the live project.
3. Give me the exact file(s) to run on the live project, in order, with a rollback; I run them myself after a backup. Never touch live data yourself.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The live project has the same tables as local, and the app shows real data.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not copy test data into the live database.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

Do not do this

Do not point the live site at a local database.
Do not copy test data into the live database.
