Django REST Report

A versatile Django toolkit for managing reports.

JasperReports

Easily generate JasperReports from your Django views using the JasperReports Server REST API. This package handles authentication, URL construction, and maps Django responses to the correct file types automatically.

🛠 Prerequisites

Before using this package, you must have a JasperReports Server instance running.

You can host it yourself or use a cloud instance.

Ensure the REST API is accessible (typically at port 8080).

🚀 Installation

pip install djangorestreport

⚙️ Setup

Add your JasperServer credentials to your Django settings.py.

# settings.py
JASPER_SERVER_URL = "http://server-ip:8080"
JASPER_USER = "username"
JASPER_PASSWORD = "password"

You can also load these values from environment variables if that matches your project setup.

📄 Supported Formats

Pass these strings into the fmt parameter to receive the corresponding file type:

Documents: pdf, docx, rtf, odt, html, xml

Spreadsheets: xlsx, xls, csv, ods

Presentations: pptx

📖 Usage

Basic Example (DRF View)

In your views.py, you can extract query parameters from the URL and pass them directly to your Jasper report.

from rest_report import JasperReport
from rest_framework.views import APIView
from rest_framework.response import Response

class ReportView(APIView):
    def get(self, request):
        report = JasperReport()

        # 1. Path to the report unit in your JasperServer repository
        report_path = "/organization/reports/NameofReport"

        # 2. Get all query params (e.g., ?id=5&status=active)
        params = request.query_params.dict()

        # 3. Extract the format (default to 'pdf')
        fmt = params.pop("fmt", "pdf")

        # 4. Generate and return the report as a file download
        try:
            return report.generate(report_path, fmt=fmt, params=params)
        except Exception as e:
            return Response({"error": str(e)}, status=400)

Extended Example (DRF View)

In your views.py, you can set a custom filename and message, then pass them directly to your Jasper report.

from rest_report import JasperReport
from rest_framework.views import APIView
from rest_framework.response import Response

class ReportView(APIView):
    def get(self, request):
        report = JasperReport()
        report_path = "/organization/reports/SalesOverview"
        
        # Extract format and parameters
        params = request.query_params.dict()
        fmt = params.pop("fmt", "pdf")

        try:
            return report.generate(
                report_path, 
                fmt=fmt, 
                params=params,
                filename="Monthly_Sales_Report",  # 1. Custom Filename
                message="Report generated successfully for User ID 101"  # 2. Custom Message
            )
        except Exception as e:
            return Response({"error": str(e)}, status=400)

💡 Working with Parameters

The params dictionary keys must exactly match the parameter names defined in your .jrxml file. For example, if you pass {"id": 10}, your Jasper report should have a parameter defined as $P{id}.
