# PDF Generation Issue - Complete Solution Guide
|
|
|
|
## 🚨 **Current Problem**
|
|
The Docker build is failing because the package `libgdk-pixbuf2.0-0` has no installation candidate in the `python:3.11-slim` base image.
|
|
|
|
## 🔧 **Immediate Solutions**
|
|
|
|
### **Option 1: Use ReportLab Fallback (Works Now)**
|
|
The system already has a ReportLab fallback that generates functional PDFs without system dependencies.
|
|
|
|
**Pros:**
|
|
- ✅ Works immediately
|
|
- ✅ No system dependencies required
|
|
- ✅ Faster generation
|
|
- ✅ Company branding included
|
|
|
|
**Cons:**
|
|
- ⚠️ Basic styling only
|
|
- ⚠️ No CSS support
|
|
- ⚠️ Limited layout control
|
|
|
|
**How to use:**
|
|
1. The system automatically falls back to ReportLab when WeasyPrint fails
|
|
2. You'll get a warning message but PDFs will still be generated
|
|
3. Company branding and invoice information will be included
|
|
|
|
### **Option 2: Fix WeasyPrint Dependencies (Recommended for Quality)**
|
|
|
|
#### **Step 1: Use Alternative Dockerfile**
|
|
```bash
|
|
# Use the WeasyPrint-optimized Dockerfile
|
|
docker-compose -f docker-compose.weasyprint.yml up --build
|
|
```
|
|
|
|
#### **Step 2: Or Update Current Dockerfile**
|
|
The current Dockerfile has been updated to use `python:3.11-slim-bullseye` which has better package availability.
|
|
|
|
#### **Step 3: Rebuild Container**
|
|
```bash
|
|
docker-compose down
|
|
docker-compose build --no-cache
|
|
docker-compose up
|
|
```
|
|
|
|
## 📋 **What's Been Created**
|
|
|
|
### **New Files:**
|
|
- `Dockerfile.weasyprint` - Optimized for WeasyPrint
|
|
- `docker-compose.weasyprint.yml` - Uses the optimized Dockerfile
|
|
- `docker/test-packages.py` - Tests system package availability
|
|
- `docker/test-pdf-generation.py` - Tests PDF generation capabilities
|
|
|
|
### **Updated Files:**
|
|
- `Dockerfile` - Now uses `python:3.11-slim-bullseye`
|
|
- `docker/start-new.sh` - Includes package and PDF testing
|
|
- `app/utils/pdf_generator_fallback.py` - ReportLab fallback generator
|
|
|
|
## 🚀 **Quick Start Options**
|
|
|
|
### **Option A: Use ReportLab Fallback (Immediate)**
|
|
```bash
|
|
# Just start the existing system
|
|
docker-compose up
|
|
# PDFs will work with ReportLab fallback
|
|
```
|
|
|
|
### **Option B: Use WeasyPrint (High Quality)**
|
|
```bash
|
|
# Use the WeasyPrint-optimized setup
|
|
docker-compose -f docker-compose.weasyprint.yml up --build
|
|
```
|
|
|
|
### **Option C: Fix Current Setup**
|
|
```bash
|
|
# Update and rebuild current setup
|
|
docker-compose down
|
|
docker-compose build --no-cache
|
|
docker-compose up
|
|
```
|
|
|
|
## 🧪 **Testing Your Setup**
|
|
|
|
### **Test System Packages:**
|
|
```bash
|
|
docker exec -it your-container-name python /app/docker/test-packages.py
|
|
```
|
|
|
|
### **Test PDF Generation:**
|
|
```bash
|
|
docker exec -it your-container-name python /app/docker/test-pdf-generation.py
|
|
```
|
|
|
|
### **Test PDF Export:**
|
|
1. Create or view an invoice
|
|
2. Click "Export PDF"
|
|
3. Check if it works and what quality you get
|
|
|
|
## 📊 **Expected Results**
|
|
|
|
### **With ReportLab Fallback:**
|
|
- ✅ PDFs generate successfully
|
|
- ✅ Company branding included
|
|
- ✅ Invoice information complete
|
|
- ⚠️ Basic styling only
|
|
- ⚠️ Warning message displayed
|
|
|
|
### **With WeasyPrint Working:**
|
|
- ✅ High-quality PDFs
|
|
- ✅ Professional styling
|
|
- ✅ CSS support
|
|
- ✅ Company logos (if configured)
|
|
- ✅ Print-ready output
|
|
|
|
## 🔍 **Troubleshooting**
|
|
|
|
### **If Build Still Fails:**
|
|
1. Check your Debian version: `cat /etc/debian_version`
|
|
2. Verify package names: `apt-cache search libgdk-pixbuf`
|
|
3. Use the alternative Dockerfile: `Dockerfile.weasyprint`
|
|
|
|
### **If PDFs Don't Generate:**
|
|
1. Check container logs: `docker-compose logs app`
|
|
2. Run package test: `python /app/docker/test-packages.py`
|
|
3. Run PDF test: `python /app/docker/test-pdf-generation.py`
|
|
|
|
### **If Only Basic PDFs Work:**
|
|
This is expected with ReportLab fallback. To get high-quality PDFs:
|
|
1. Use `Dockerfile.weasyprint`
|
|
2. Or fix system dependencies in current setup
|
|
|
|
## 🎯 **Recommended Approach**
|
|
|
|
### **For Immediate Use:**
|
|
1. Use ReportLab fallback (already working)
|
|
2. Configure company branding in Admin → Settings
|
|
3. Generate PDFs with basic styling
|
|
|
|
### **For Production Quality:**
|
|
1. Use `docker-compose.weasyprint.yml`
|
|
2. Rebuild with WeasyPrint support
|
|
3. Enjoy professional-grade PDFs
|
|
|
|
### **For Development:**
|
|
1. Start with ReportLab fallback
|
|
2. Gradually fix WeasyPrint dependencies
|
|
3. Test both generators
