Hi Alessio
If you call from Apache then you can call subprocess directly from
webserver but in nginx you have to use schedule task. Better to run
wkhtmltopdf via schedule task in case of generate pdf or process a report.
THIS IS MY CODE:
def schedule_task__pdf_render():
# import
import os, re
from subprocess import call
body_html_path = os.path.join(request.folder, "static",
"template/paper__body.html")
header_html_path = os.path.join(request.folder, "static",
"template/paper__header.html")
footer_html_path = os.path.join(request.folder, "static",
"template/paper__footer.html")
result_pdf_path = os.path.join(request.folder, "static",
"template/%s.pdf" %print_job__id)
# body
html = response.render('controller_name/my_html_page.html')
file(body_html_path, "wb").write(html)
# header
html = response.render('controller_print_template/my_page_header.html')
file(header_html_path, "wb").write(html)
# footer
html = response.render('controller_print_template/my_page_footer.html')
file(footer_html_path, "wb").write(html)
call('wkhtmltopdf --javascript-delay 10000 --margin-top 30mm
--margin-left 20 --margin-right 20 --margin-bottom 30mm %s --header-html
%s --footer-html %s %s' %(body_html_path,
header_html_path,footer_html_path, result_pdf_path), shell=True)
return
NOTE :
1. Use --javascript-delay 10000 in case of waiting for javascript complete
their work, ie. waiting mathjax to complete math formula conversion to html
page.
2. This case I render html from file, not render direct from online html
page because my html page is not a static page.
3. Sample of my_html_page.html
{{
paper__id = request.vars.paper__id
paper__row = db.paper[paper__id]
}}
<div>
<div class='title-in-english'>
{{=XML(paper__row.title_in_english)}}
</div>
<div class='authours-in-english'>
{{=XML(paper__row.authours_in_english)}}
</div>
<div class='content-body'>
{{=XML(i.paper_content_body)}}
</div>
</div>
Hope it help.
:)
