I need help with attaching img file in pdfs. We use the WeasyPrint lib for generating pdf from html.
in html connect img file like this
<img src="1.png" alt="">
<img src="2.png" alt="">
<img src="3.png" alt="">
but it is not working. I don't see the image.
use static for path of the image file
{% load static %}
<img src="{% static 'images/static.jpg' %}" alt="">
and pass base_url in HTML class in views.py
pdf_file = HTML(string=rendered_html, base_url=request.build_absolute_uri())
html file
<!DOCTYPE html>
<html lang="en">
{% load static %}
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div>
<img src="{% static 'images/static.jpg' %}" alt="">
</div>
</body>
</html>
views.py
from django.template.loader import get_template
from weasyprint import HTML, CSS
from django.conf import settings
from django.http import HttpResponse
def generate_pdf(request):
html_template = get_template('latest/html_pdf.html')
user = request.user
rendered_html = html_template.render().encode(encoding="UTF-8")
pdf_file = HTML(string=rendered_html, base_url=request.build_absolute_uri()).write_pdf(stylesheets=[CSS(settings.STATIC_ROOT + '/css/generate_html.css')])
http_response = HttpResponse(pdf_file, content_type='application/pdf')
http_response['Content-Disposition'] = 'filename="generate_html.pdf"'
return http_response
In case of sending emails with pdf attached, it's possible to pass path from view to function dedicated to emails. views.py
[...]
path = request.build_absolute_uri() # build absolute path
order_confirmation.delay(order.id, path) # pass to func
[...]
tasks.py
@app.task
def order_confirmation(order_id, path): # receive path
order = Order.objects.get(id=order_id)
subject = f"Order nr. {order.id}"
email_from = settings.EMAIL
email_to = order.get_email
message = (...)
email = EmailMessage(subject, message, email_from, [email_to])
html = render_to_string('pdf.html', {'order' : order, 'company': company})
out = BytesIO()
stylesheets=[weasyprint.CSS(settings.STATIC_ROOT + '/css/pdf.css')]
weasyprint.HTML(string=html, base_url=path).write_pdf(out, stylesheets=stylesheets) # use here
email.attach(f'order_{order.id}.pdf',
out.getvalue(),
'application/pdf')
email.send()
