Haltr uses wkhtmltopdf to generate PDF files.
In order to run wkhtmltopdf in a headless server you can use xvfb.
apt-get install wkhtmltopdf xvfb
then, put this script in /usr/local/bin/wkhtmltopdf
#!/bin/sh xvfb-run -a -s "-screen 0 640x480x16" /usr/bin/wkhtmltopdf $*
do not forget to give it execution permisions
chmod +x /usr/local/bin/wkhtmltopdf
Haltr is designed for use with an external mailing system, to allow to manipulate invoice file before sending it. In Spain we must digitally sign invoices before sending them.
In settings, "Path of export folders" is where Haltr leaves invoices, and expects another process scheduled to take them, do whatever transformation is needed, send them and report the status change to Haltr.
To report invoice status changes, Haltr provides a RESTful access to an ``Event`` model, which has a particular name and invoice ID.
Event.new(:invoice_id => 1, :name => "success_sending")
would change the status of the invoice with id 1, from "Sending" to "Sent".
Access to the REST service is restricted by source IP, so that events can only be created from the IP that has been set in "B2brouter IP"
Finally, "B2brouter URL" is the URL where Haltr retrieves the invoices already signed, so that they can be downloaded.
The call looks like this:
