Yep, Python is at it again…
Why to keep your PDF’s as bytea and suffer with editing them (if thats even possible)?
Store it as a HTML in the table, on INSERT/UPDATE generate pdf and save to disk and keep only the file URL in the DB (saves ton of time on replication)
txt : string to convert
filename: save as …
folder: target folder
I created a custom type to accommodate the result - and to explain how to handle returns from python functions.
create type type_text2pdf as
(
url text,
file bytea
);create function sm_text2pdf
(txt text, filename text, folder text
) returns type_text2pdf
language plpython3u
as
$$
import pdfkit
import os
t,f = args[0],args[1]
fn='/files/'+folder+'/'+f
r=pdfkit.from_string(t,fn)
in_file=open(fn,"rb")
data=in_file.read()
return fn, data
$$;
And usage:
/*
select * from sm_text2pdf($$<html>yay!</html>$$,'a.pdf','docs');
*/PDF will be saved as/files/docs/a.pdf
Function will return file URL and file itself
