+# FastAPI Admin 1.0.4 Migration Guide
+
+**Date:** March 22, 2026
+**Status:** In Progress - Needs Completion
+**Priority:** High (Blocking Deployment)
+
+---
+
+## Problem
+
+The `requirements.txt` specified `fastapi-admin>=1.4.0` but only version `1.0.4` is available on PyPI. The API between these versions is completely different, causing multiple `AttributeError` crashes on startup.
+
+---
+
+## What's Been Fixed (Partially)
+
+### 1. `inputs.Select` - Line 135, 141, 147, 189, 223, 255, 285, 350
+
+**Before (1.4.0 API):**
+```python
+input_=inputs.Select(options=["ctt", "irt", "hybrid"], default="ctt")
+```
+
+**After (1.0.4 API):**
+```python
+input_=inputs.Select(default="ctt")  # No 'options' parameter
+```
+
+**Fix Applied:** ✅ Yes (via sed)
+
+---
+
+### 2. `displays.Select` - Multiple lines
+
+**Before:**
+```python
+display=displays.Select(choices=["ctt", "irt", "hybrid"])
+```
+
+**After:**
+```python
+display=displays.Display()  # Select doesn't exist
+```
+
+**Fix Applied:** ✅ Yes (via sed)
+
+---
+
+### 3. `displays.DateTime` - Multiple lines
+
+**Before:**
+```python
+display=displays.DateTime()
+```
+
+**After:**
+```python
+display=displays.DatetimeDisplay()  # Note the capital 'D' and lowercase 'i'
+```
+
+**Fix Applied:** ✅ Yes (via sed)
+
+---
+
+### 4. `displays.Text` - Line 230+
+
+**Before:**
+```python
+display=displays.Text(maxlen=100)
+```
+
+**After:**
+```python
+display=displays.Display()  # Text doesn't exist
+```
+
+**Fix Applied:** ✅ Yes (via sed)
+
+---
+
+## What Still Needs Fixing
+
+### 5. `admin_app.settings` - Lines 602-606
+
+**Current Error:**
+```
+AttributeError: 'FastAPIAdmin' object has no attribute 'settings'
+```
+
+**Current Code (Lines 600-610):**
+```python
+# Configure admin app
+admin_app.settings.logo_url = "/static/logo.png"
+admin_app.settings.site_title = "IRT Bank Soal Admin"
+admin_app.settings.site_description = "Admin Panel for Adaptive Question Bank System"
+
+# Register authentication provider
+admin_app.settings.auth_provider = AdminAuthProvider()
+```
+
+**Needs Investigation:**
+Check how to configure FastAPIAdmin in 1.0.4:
+```bash
+python3 -c "from fastapi_admin.app import app; print(dir(app))"
+```
+
+Likely need to pass settings during initialization or use a different configuration method.
+
+---
+
+### 6. Custom Link Resources - Lines 617-620
+
+**Current Code:**
+```python
+# Register dashboard links
+admin_app.register(CalibrationDashboardLink)
+admin_app.register(ItemStatisticsLink)
+admin_app.register(SessionOverviewLink)
+```
+
+**Needs Investigation:**
+Check if `Link` resource type exists in 1.0.4 and if `admin_app.register()` works the same way.
+
+---
+
+## Available Classes in 1.0.4
+
+### `fastapi_admin.widgets.inputs`
+```
+Color, Date, DateTime, DisplayOnly, Editor, Email, Enum, File, FileUpload,
+ForeignKey, Image, Input, Json, List, ManyToMany, Model, Number, Password,
+Radio, RadioEnum, Select, Switch, Text, TextArea
+```
+
+**Note:** `Select` only accepts: `help_text`, `default`, `null`, `disabled`
+
+### `fastapi_admin.widgets.displays`
+```
+Boolean, DateDisplay, DatetimeDisplay, Display, Image, InputOnly, Json
+```
+
+**Note:** No `Select`, `Text`, `Number` - use `Display` instead
+
+---
+
+## Commands to Complete Migration
+
+### Step 1: Check FastAPIAdmin available attributes
+```bash
+cd /www/wwwroot/irt-bank-soal
+source venv/bin/activate
+python3 -c "from fastapi_admin.app import app; print([x for x in dir(app) if not x.startswith('_')])"
+```
+
+### Step 2: Read the create_admin_app function
+```bash
+sed -n '590,630p' /www/wwwroot/irt-bank-soal/app/admin.py
+```
+
+### Step 3: Check how to initialize FastAPIAdmin properly
+Look at fastapi-admin 1.0.4 documentation or source code to understand:
+- How to set logo_url
+- How to set site_title
+- How to set site_description
+- How to register auth provider
+- How to register resources
+
+### Step 4: Fix the admin configuration
+Rewrite `create_admin_app()` function to use 1.0.4 API
+
+### Step 5: Test
+```bash
+pm2 restart irt-bank-soal
+sleep 3
+pm2 logs irt-bank-soal --lines 10
+curl http://127.0.0.1:8000/
+```
+
+---
+
+## Quick Fix Option (Disable Admin Panel)
+
+If admin panel is not immediately needed, temporarily disable it:
+
+**In `app/main.py` line 19:**
+```python
+# Temporarily disabled for 1.0.4 migration
+# from app.admin import admin as admin_app
+admin_app = None
+```
+
+**And comment out the mounting code:**
+```python
+# if admin_app:
+#     app.mount("/admin", admin_app)
+```
+
+This allows the main API to run while admin panel is being fixed.
+

+
+## Files Modified
+
+| File | Status |
+|------|--------|
+| `requirements.txt` | Changed `fastapi-admin>=1.4.0` to `fastapi-admin>=1.0.0` |
+| `app/admin.py` | Partially fixed (inputs.Select, displays.*) |
+
+---
+
+## Remaining Tasks
+
+- [ ] Fix `admin_app.settings` configuration
+- [ ] Verify `admin_app.register()` works for Model resources
+- [ ] Verify Link resources work
+- [ ] Test admin panel at `/admin` endpoint
+- [ ] Document final working configuration
+
+---
+
+## Reference: Full Admin File
+
+To see the full admin.py file:
+```bash
+cat /www/wwwroot/irt-bank-soal/app/admin.py
+```

+
+**Document End**
+
+**Next Agent:** Complete the admin configuration fix and verify the app starts successfully.
