how to post

Good — this helps pinpoint the issue exactly 👍

Your current policy:

`sql alter policy "Users can insert their own posts" on "public"."posts" to public with check ( (auth.uid() = author_id) ); `

---

🚨 What’s wrong (2 key problems)

❌ 1. `TO public`

• `public` = **anyone (even not logged in)**
• But `auth.uid()` only works for **authenticated users**

👉 This creates a mismatch → policy fails

---

❌ 2. Column mismatch (`author_id` vs your code)

Earlier we used:

`sql user_id `

Now your policy uses:

`sql author_id `

👉 If your insert is sending user_id but policy checks author_id → ❌ RLS blocks it

---

✅ Fix (Clean & Correct)

Option A (Recommended — use `author_id`)

If your table uses author_id, then fix policy like this:

`sql ALTER POLICY "Users can insert their own posts" ON public.posts TO authenticated WITH CHECK (auth.uid() = author_id); `

---

Option B (If your column is `user_id`)

`sql ALTER POLICY "Users can insert their own posts" ON public.posts TO authenticated WITH CHECK (auth.uid() = user_id); `

---

🔥 MOST IMPORTANT: Match your code

Your insert MUST match the column:

If using `author_id`:

`js await supabase.from('posts').insert([ { title, content, author_id: user.id // ✅ MUST match policy } ]) `

---

🧪 Quick Debug Checklist

• [ ] Is user logged in?
• [ ] Column name matches? (`author_id` vs `user_id`)
• [ ] Policy uses `TO authenticated` (NOT public)
• [ ] Insert includes that column

---

⚡ Fast Test (to confirm issue)

Temporarily run:

`sql ALTER POLICY "Users can insert their own posts" ON public.posts TO authenticated WITH CHECK (true); `

👉 If it works → issue is 100% column mismatch

---

🧠 Final Answer

✔ Your policy exists — good ❌ But:

• Wrong role (`public`)
• Possible column mismatch

👉 Fix those → error gone instantly

---

If you want, paste your:

• `posts` table structure
• `createPost` code

I’ll align everything perfectly so it just works 👍
