This approach worked for me in Python using below libraries:
Jinja2 - for generating HTML with custom data
xhtml2pdf - for generating PDF from HTML
Consider within your PROJECT DIR, there is a template file(invoice.html) and python file(pdf_generator.py)
pdf_generator.py
from xhtml2pdf import pisa
import jinja2
templateLoader = jinja2.FileSystemLoader(searchpath="./")
templateEnv = jinja2.Environment(loader=templateLoader)
TEMPLATE_FILE = "invoice.html"
template = templateEnv.get_template(TEMPLATE_FILE)
# This data can come from database query
body = {
"data":{
"order_id": 123,
"order_creation_date": "2020-01-01 14:14:52",
"company_name": "Test Company",
"city": "Mumbai",
"state": "MH",
}
}
# This renders template with dynamic data
sourceHtml = template.render(json_data=body["data"])
outputFilename = "invoice.pdf"
# Utility function
def convertHtmlToPdf(sourceHtml, outputFilename):
# open output file for writing (truncated binary)
resultFile = open(outputFilename, "w+b")
# convert HTML to PDF
pisaStatus = pisa.CreatePDF(
src=sourceHtml, # the HTML to convert
dest=resultFile) # file handle to receive result
# close output file
resultFile.close()
# return True on success and False on errors
print(pisaStatus.err, type(pisaStatus.err))
return pisaStatus.err
if __name__ == "__main__":
pisa.showLogging()
convertHtmlToPdf(sourceHtml, outputFilename)
invoice.html
<!DOCTYPE html>
<html lang="en">
<body>
Name: {{ json_data.company_name }} <br>
City/State: {{ json_data.city }}, {{ json_data.state }} <br>
Date: {{ json_data.order_creation_date }} <br>
Order ID: {{ json_data.order_id }} <br>
</body>
</html>
