Hello @kartik,
Use this code to generate the PDF from html template :
import os
from weasyprint import HTML
from django.template import Template, Context
from django.http import HttpResponse
def generate_pdf(self, report_id):
# Render HTML into memory and get the template firstly
template_file_loc = os.path.join(os.path.dirname(__file__), os.pardir, 'templates', 'the_template_pdf_generator.html')
template_contents = read_all_as_str(template_file_loc)
render_template = Template(template_contents)
#rendering_map is the dict for params in the template
render_definition = Context(rendering_map)
render_output = render_template.render(render_definition)
# Using Rendered HTML to generate PDF
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename=%s-%s-%s.pdf' % \
('topic-test','topic-test', '2018-05-04')
# Generate PDF
pdf_doc = HTML(string=render_output).render()
pdf_doc.pages[0].height = pdf_doc.pages[0]._page_box.children[0].children[
0].height # Make PDF file as single page file
pdf_doc.write_pdf(response)
return response
def read_all_as_str(self, file_loc, read_method='r'):
if file_exists(file_loc):
handler = open(file_loc, read_method)
contents = handler.read()
handler.close()
return contents
else:
return 'file not exist'
Hope it helps!!
Thank you!!
