# 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
