CRON and Script aren't working together.

[magpie]

I have a violin on a python that works at the corners in the consoles. Crypt in the console:

cd /root/bill
source bin/activate
puthon filegen.py

The violin itself has a logic: running on the table in the mongo, getting HTML, generating a PDF from it, and clicking the tape as completed:

#!/root/bill/bin/python
# coding: utf-8
from future import unicode_literals

from mongoengine import *

import datetime

import time

import calendar
from io import BytesIO as IO

import gzip
import pdfkit

import pytils
from bson import json_util

from bson.json_util import dumps

from bson.objectid import ObjectId
import sys

import random

reload(sys)  # Reload does the trick!

sys.setdefaultencoding('UTF8')
connect(host='mongodb://main:PWD@HOST/bill?ssl=true&ssl_cert_reqs=CERT_NONE')
class Genq(Document):

dokstring = StringField()

outpdf = StringField()
print ("started")
foreva = True
while foreva:

print ("....")

reqs = Genq.objects()

for doc in reqs:

print ("++++++")

pdfkit.from_string(doc.dokstring, doc.outpdf)

print (">>>>>>")

doc.delete()

print ("!!!!!!!")

I'm trying to launch this eternal crypt in the crown by team:

@reboot /root/bill/bin/python /root/bill/filegen.py >>/var/log/syslof

I get the following message in the console:

root@bill2:~# tail 50 /var/log/syslog

tail: cannot open ‘50’ for reading: No such file or directory

==> /var/log/syslog <==

started

....

I understand the violin goes somewhere on the line:

pdfkit.from_string(doc.dokstring, doc.outpdf)

But why does the console do what you need?

All I've learned is that the crown has some sort of environment that doesn't see the file system or the library. pdfkit, though I'm starting it from the mouth.

Based on the line source bin/activate - you're using. virtualenv Or his fork/clon. virtualenv - is a separate environment with other ways in which modules that are not available in a system-based python can be installed (cot is default for all UNIX users)

So make wrapper-file, where the right environment can be established:

run_me.sh:

#!/bin/bash
export VIRTUAL_ENV=/root/bill

cd $VIRTUAL_ENV

source $VIRTUAL_ENV/bin/activate

$VIRTUAL_ENV/bin/python /path/to/filegen.py

and start it out. CRONTABYeah.
