Django integration for docxtpl - generate documents from Word templates with multi-format export

django-docxtpl

Django integration for docxtpl - generate documents from Word templates with Jinja2 syntax and export to multiple formats.

Features

• 📝 Generate Word documents (.docx) from templates using Jinja2 syntax
• 📄 Export to multiple formats: DOCX, PDF, ODT, HTML, TXT
• 🔄 Automatic format conversion via LibreOffice headless
• 📑 Update Table of Contents (TOC), charts, and dynamic fields automatically
• 🎯 Simple API with DocxTemplateResponse
• 🏗️ Class-based views with DocxTemplateView and DocxTemplateDetailView
• ⚡ Automatic file extension based on output format

Installation

pip install django-docxtpl

For PDF and other format conversions, you'll need LibreOffice installed:

# Ubuntu/Debian
sudo apt install libreoffice-core libreoffice-writer

# Ubuntu/Debian (headless server - minimal installation)
sudo apt install libreoffice-core libreoffice-writer-nogui

# macOS
brew install --cask libreoffice

# Alpine Linux (Docker)
apk add libreoffice-writer

# RHEL/CentOS/Fedora
sudo dnf install libreoffice-writer

Quick Start

1. Add to INSTALLED_APPS (optional)

INSTALLED_APPS = [
    ...
    "django_docxtpl",
]

2. Create a Word template

Create a .docx file with Jinja2 placeholders:

Hello {{ name }}!

Your order #{{ order_number }} has been confirmed.

3. Use in your views

Function-based view:

from django_docxtpl import DocxTemplateResponse

def generate_document(request):
    context = {
        "name": "John Doe",
        "order_number": "12345",
    }
    return DocxTemplateResponse(
        request,
        template="documents/order.docx",
        context=context,
        filename="order_confirmation",  # Extension added automatically
        output_format="pdf",  # or "docx", "odt", "html", "txt"
    )

Class-based view:

from django_docxtpl import DocxTemplateView

class OrderDocumentView(DocxTemplateView):
    template_name = "documents/order.docx"
    filename = "order_confirmation"
    output_format = "pdf"

    def get_context_data(self, **kwargs):
        return {
            "name": self.request.user.get_full_name(),
            "order_number": kwargs.get("order_id"),
        }

Detail view for model instances:

from django_docxtpl import DocxTemplateDetailView

class InvoiceDocumentView(DocxTemplateDetailView):
    model = Invoice
    template_name = "documents/invoice.docx"
    output_format = "pdf"
    context_object_name = "invoice"

    def get_filename(self):
        return f"invoice_{self.object.number}"

Configuration

Add these optional settings to your settings.py:

# Directory where your .docx templates are stored
DOCXTPL_TEMPLATE_DIR = BASE_DIR / "docx_templates"

# Path to LibreOffice executable (auto-detected if not set)
DOCXTPL_LIBREOFFICE_PATH = "/usr/bin/soffice"

Supported Output Formats

Format	Extension	Requires LibreOffice
DOCX	.docx	No (Yes if update_fields=True)
PDF	.pdf	Yes
ODT	.odt	Yes
HTML	.html	Yes
TXT	.txt	Yes

Template Syntax

django-docxtpl uses docxtpl which supports full Jinja2 syntax:

{% for item in items %}
- {{ item.name }}: {{ item.price }}€
{% endfor %}

Total: {{ total }}€

{% if discount %}
Discount applied: {{ discount }}%
{% endif %}

See the docxtpl documentation for advanced features like images, tables, and rich text.

Updating TOC and Charts

If your template contains a Table of Contents (TOC), charts, or other dynamic fields that need to be updated after rendering, use the update_fields parameter:

# Function-based view
return DocxTemplateResponse(
    request,
    template="reports/annual_report.docx",
    context=context,
    output_format="pdf",
    update_fields=True,  # Updates TOC, charts, page numbers, etc.
)

# Class-based view
class AnnualReportView(DocxTemplateView):
    template_name = "reports/annual_report.docx"
    output_format = "pdf"
    update_fields = True

Note: This feature requires LibreOffice, even when output format is DOCX.

Working with Images (InlineImage)

To insert images in your documents, use docxtpl's InlineImage. Since it requires access to the DocxTemplate instance, use get_context_data_with_docx() in class-based views or a callable context in function-based views:

Class-based view:

from docxtpl import InlineImage
from docx.shared import Mm
from django_docxtpl import DocxTemplateView

class ReportWithLogoView(DocxTemplateView):
    template_name = "reports/report.docx"
    output_format = "pdf"

    def get_context_data_with_docx(self, docx, **kwargs):
        """Build context with access to DocxTemplate instance."""
        return {
            "title": "Annual Report",
            "logo": InlineImage(docx, "static/logo.png", width=Mm(30)),
        }

Function-based view:

from docxtpl import InlineImage
from docx.shared import Mm
from django_docxtpl import DocxTemplateResponse

def report_with_image(request):
    def build_context(docx):
        return {
            "title": "Report",
            "logo": InlineImage(docx, "static/logo.png", width=Mm(30)),
        }

    return DocxTemplateResponse(
        request,
        template="reports/report.docx",
        context=build_context,  # Callable receives DocxTemplate instance
        output_format="pdf",
    )

See the advanced documentation for more examples.

Performance Considerations

Document generation, especially PDF conversion with LibreOffice, can be slow (1-5 seconds per document). For production environments, consider:

1. Use a task queue - Offload document generation to background workers using Celery, Django-RQ, or Huey:

Example 1:

# tasks.py (Huey example)
from huey.contrib.djhuey import task
from django.core.files.base import ContentFile
from django_docxtpl.converters import convert_docx
from docxtpl import DocxTemplate
from io import BytesIO

@task()
def generate_report_pdf(report_id):
    report = Report.objects.get(pk=report_id)
    
    doc = DocxTemplate("templates/report.docx")
    doc.render({"report": report})
    
    buffer = BytesIO()
    doc.save(buffer)
    buffer.seek(0)
    
    pdf_content = convert_docx(buffer, "pdf", update_fields=True)
    
    # Save to storage, send email, etc.
    report.pdf_file.save(f"report_{report_id}.pdf", ContentFile(pdf_content))

Example 2:

# tasks.py (Huey example) - Using render_to_file utility
from huey.contrib.djhuey import task
from django_docxtpl import render_to_file

@task()
def generate_report_to_disk(output_dir, filename, context):
    """Generate a document and save it to disk."""
    output_path = render_to_file(
        template="reports/monthly.docx",
        context=context,
        output_dir=output_dir,
        filename=filename,
        output_format="pdf",
        update_fields=True,
    )
    return str(output_path)

2. Serve DOCX when possible - Skip LibreOffice conversion for faster response times
3. Cache generated documents - Store frequently requested documents

API Reference

DocxTemplateResponse

DocxTemplateResponse(
