A Light Django Application which uses selenium to convert any html page to pdf. Using this approach you can easily make pdf of HTML pages with charts, tables and having their loaded Styles.

pip install django-selenium-pdfmaker

Then add package name django_selenium_pdfmaker to the INSTALLED_APPS of django.

Usage

To use this module:

pdfmaker = PDFMaker()
res = pdfmaker.get_pdf_from_html(url='https://google.com', filename='output', write=True)

and res includes:

{
  "status": true,
  "raw": "pdf in binary format",
  "pdf": "ConvertedPDF instance if write flag is True.",

Exceptions

1- Message: session not created: This version of ChromeDriver only supports Chrome version 90 Current browser version is 103.0.5060.53 with binary path /usr/bin/google-chrome

If you faced a problem like this, you should address the correct chromedriver binary in your codes. To do that download the proper chromedriver version and place in your OS. Then address it with following option in your settings.py file:

CHROMEDRIVER_PATH = '/usr/bin/chromedriver'

Also you can use below script to automatically fix this problem:

pip install webdriver-manager

Then use the driver in python as follows

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())
