# GigLez Web App Startup Guide
|
||||
|
||||
## Problem: Errors When Starting Web App
|
||||
|
||||
When running `python3 src/api/main.py`, you encountered multiple errors. Here's what was causing them and how to fix it.
|
||||
|
||||
---
|
||||
|
||||
## Root Causes
|
||||
|
||||
### 1. Import Path Conflict ❌
|
||||
|
||||
**Error**:
|
||||
```
|
||||
ImportError: cannot import name 'settings' from 'config.settings'
|
||||
```
|
||||
|
||||
**Cause**: Python was importing from the system `config` package instead of the local `config/settings.py`
|
||||
|
||||
**Fix**: Added `sys.path.insert(0, ...)` to prioritize local imports
|
||||
|
||||
### 2. Database Connection Requirement ❌
|
||||
|
||||
**Error**: Application hangs/fails during startup trying to connect to PostgreSQL
|
||||
|
||||
**Cause**: The main API (`src/api/main.py`) requires:
|
||||
- PostgreSQL database connection
|
||||
- PostGIS extension
|
||||
- Database initialization
|
||||
|
||||
**The startup lifecycle includes**:
|
||||
```python
|
||||
# Test database connection
|
||||
db_config = get_db_config()
|
||||
if not db_config.test_connection():
|
||||
raise RuntimeError("Database connection failed")
|
||||
|
||||
if not db_config.test_postgis():
|
||||
raise RuntimeError("PostGIS extension not available")
|
||||
```
|
||||
|
||||
This blocks startup if PostgreSQL isn't configured.
|
||||
|
||||

|
||||
|
||||
## Solutions
|
||||
|
||||
### Option 1: Simplified Web Server ✅ (Recommended for Testing)
|
||||
|
||||
**File**: `src/api/main_simple.py`
|
||||
|
||||
**Features**:
|
||||
- ✅ Serves web interface (HTML, CSS, JS)
|
||||
- ✅ No database requirement
|
||||
- ✅ Mock API endpoints (empty data)
|
||||
- ✅ Perfect for testing UI/UX
|
||||
|
||||
**Start command**:
|
||||
```bash
|
||||
python3 src/api/main_simple.py
|
||||
```
|
||||
|
||||
**Access**:
|
||||
```
|
||||
Web Interface: http://localhost:8000
|
||||
API Docs: http://localhost:8000/docs
|
||||
Health Check: http://localhost:8000/health
|
||||
```
|
||||
|
||||
**Limitations**:
|
||||
- ❌ Cannot upload files
|
||||
- ❌ No database queries
|
||||
- ❌ No device matching
|
||||
- ✅ Map, search, and stats work (with empty data)
|
||||
|
||||
### Option 2: Full API Server (Requires Database Setup)
|
||||
|
||||
**File**: `src/api/main.py`
|
||||
|
||||
**Requirements**:
|
||||
1. PostgreSQL installed and running
|
||||
2. Database and user created
|
||||
3. PostGIS extension installed
|
||||
|
||||
**Setup steps**:
|
||||
```bash
|
||||
# Run database setup script
|
||||
./scripts/quick_db_setup.sh
|
||||
|
||||
# OR manually:
|
||||
sudo -u postgres psql
|
||||
CREATE USER giglez_user WITH PASSWORD 'giglez_secure_password_2026';
|
||||
CREATE DATABASE giglez OWNER giglez_user;
|
||||
\c giglez
|
||||
CREATE EXTENSION postgis;
|
||||
```
|
||||
|
||||
**Start command**:
|
||||
```bash
|
||||
python3 src/api/main.py
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Current Status
|
||||
|
||||
### ✅ Working Now (Simplified Server)
|
||||
|
||||
```bash
|
||||
# Server is running
|
||||
python3 src/api/main_simple.py
|
||||
|
||||
# Output:
|
||||
# INFO: Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
|
||||
# INFO: Application startup complete.
|
||||
```
|
||||
|
||||
**Test it**:
|
||||
```bash
|
||||
# Health check
|
||||
curl http://localhost:8000/health
|
||||
# Response: {"status":"healthy","database":"not_connected","mode":"simple"}
|
||||
|
||||
# Web interface
|
||||
# Open browser: http://localhost:8000
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Web Interface Features (Working Now)
|
||||
|
||||
### ✅ Available
|
||||
- Interactive map (Leaflet.js)
|
||||
- Navigation between sections
|
||||
- Responsive design
|
||||
- Statistics dashboard (shows 0s without data)
|
||||
- Search interface (no results without data)
|
||||
- Upload form (UI only, backend disabled)
|
||||
|
||||
### ⏳ Requires Full Server + Database
|
||||
- File uploads
|
||||
- Device matching
|
||||
- Database queries
|
||||
- Real capture data on map
|
||||
|
||||

|
||||
|
||||
## Startup Scripts
|
||||
|
||||
### Quick Start (Simplified)
|
||||
|
||||
**Created**: Simple startup for testing
|
||||
|
||||
```bash
|
||||
python3 src/api/main_simple.py
|
||||
```
|
||||
|
||||
### Full Start (Requires DB)
|
||||
|
||||
```bash
|
||||
# Setup database first
|
||||
./scripts/quick_db_setup.sh
|
||||
|
||||
# Then start full server
|
||||
python3 src/api/main.py
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Error Debugging
|
||||
|
||||
### If you see: "ImportError: cannot import name 'settings'"
|
||||
|
||||
**Fix**: Already fixed in `src/api/main.py` with:
|
||||
```python
|
||||
import sys
|
||||
sys.path.insert(0, str(Path(__file__).parent.parent.parent))
|
||||
```
|
||||
|
||||
### If you see: "Database connection failed"
|
||||
|
||||
**Options**:
|
||||
1. Use simplified server: `python3 src/api/main_simple.py`
|
||||
2. Setup PostgreSQL: `./scripts/quick_db_setup.sh`
|
||||
|
||||
### If you see: "Address already in use"
|
||||
|
||||
**Cause**: Port 8000 already in use
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
# Find process
|
||||
lsof -i :8000
|
||||
|
||||
# Kill it
|
||||
kill -9 <PID>
|
||||
|
||||
# Or use different port
|
||||
python3 src/api/main_simple.py # Edit file to change port
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Testing the Web Interface
|
||||
|
||||
### 1. Start Server
|
||||
|
||||
```bash
|
||||

|
||||
```
|
||||
|
||||
### 2. Open Browser
|
||||
|
||||
```
|
||||
http://localhost:8000
|
||||
```
|
||||
|
