Without a traceback what do you expect?
Sorry for the late reply. I did not notice the message.
What I am trying to do, is generate a pdf for printing.
I get the pdf data, generate a base64 string and then generate pdf in front end.
This is a part of my code in backend:
binary_obj = xmlrpclib.Binary(open(completeName).read())
b64 = base64.b64encode(bytes(binary_obj))
return b64
where completeName
is the pdf path in backend. I generate base64 string.
And in front end, this is the code:
let printBlob = exports.printBlob = function printBlob(src) {
if (typeof window === 'undefined') {
throw new Error('You cannot print url without defined window.');
}
let iframeId = 'printf';
let iframe = document.getElementById(iframeId);
if (!iframe) {
iframe = document.createElement('iframe');
iframe.setAttribute('id', iframeId);
iframe.setAttribute('style', 'position:absolute;left:-9999px');
document.body.append(iframe);
}
iframe.setAttribute('src', src);
iframe.addEventListener('load', function () {
iframe.contentWindow.focus();
iframe.contentWindow.print();
let infanticide = function infanticide() {
iframe.parentElement.removeChild(iframe);
window.removeEventListener('focus', infanticide);
};
window.addEventListener('focus', infanticide);
});
};
I got the code JS from StackOverflow.
It opens a printing windows on Chrome but is says Bad Request. Request Line too large
.
This is most likely something from gunicorn.
in supervisor, set --limit-request-line 0
(or some other value you desire) to increase this limit
http://docs.gunicorn.org/en/latest/settings.html?highlight=limit_request_line
gunicorn or superviror ? I found the supervisor.conf file but where shuold i put it?
Any resolution?
edit the supervisor.conf in your erpnext config folder , find the line that has gunicorn text, then edit that command line by inserting the line :
--limit-request-line 0
in my supervisor conf file , it could be like this:
...
...
command=/opt/bench/erpnext2/env/bin/gunicorn -b 127.0.0.1:8001 -w 9 -t 120 --limit-request-line 0 frappe.app:application --preload
...
...
Thanks , This works for me
