Тема: Generating messages layer with python

Hello guys. I need some help creating messages layer for downloading history period of units. I have this code, works ok getting the units list, but i get this error "WialonError(Invalid input render_create_messages_layer (4))" from the render_create_messages_layer. Any advice? Thanks

from wialon.api import Wialon, WialonError
from wialon import flags
import json

starttime = "1478736000"
endtime = "1479600000"

try:
    wialon_api = Wialon()
    result = wialon_api.token_login(token='token')
    wialon_api.sid = result['eid']

    result = wialon_api.avl_evts()

    print result

    spec = {
        'itemsType': 'avl_unit',
        'propName': 'sys_name',
        'propValueMask': '*',
        'sortType': 'sys_name'
    }
    
  

    interval = {"from": 0, "to": 0}

    try:
        units = wialon_api.core_search_items(spec=spec, force=1, flags=flags.ITEM_DATAFLAG_BASE, **interval)
        for i in units['items']:
            
            gen = {
                'layerName': 'arhivamesaje',
                'itemId': i['id'],
                'timeFrom': starttime,
                'timeTo': endtime,
                'tripDetector': 0,
                'trackColor': 'cc713cff',
                'trackWidth':5,
                'arrows':1,
                'points':1,
                'pointColor':0,
                'annotations':1,
                'flags':0
            }
            
            print i['nm']
            try:
                meslayer = wialon_api.render_create_messages_layer(spec=gen)
            except WialonError as e:
                print e
    except WialonError as e:
        print e


    wialon_api.core_logout()
except WialonError as e:
    pass

Re: Generating messages layer with python

Hello

You passed wrong params to render_create_messages_layer call

// Wrong
meslayer = wialon_api.render_create_messages_layer(spec=gen)
// Right
meslayer = wialon_api.render_create_messages_layer(**gen)

Re: Generating messages layer with python

Another question.
This python script that i made, runs every night to generate and download the messages archive for all the units of a specific account, from the day before. The problem is that it generates messages from the day before at hour 02:00:32 am to next day at hour 01:59:47 am, not from 00:00:00 day before to 00:00:00 current day.

Any ideea why? Thanks

d = datetime.datetime.now().date()
d2 = d - datetime.timedelta(days=1)

timpstart = calendar.timegm(d2.timetuple())
timpsfarsit = calendar.timegm(d.timetuple())
print "Data Start " + str(d2) + ". Data sfarsit " + str(d)
print "Data start unix " + str(timpstart) + ". Data sfarsit unix " + str(timpsfarsit)

try:
    wialon_api = Wialon()
    result = wialon_api.token_login(token='TOKEEEEEENNNN')

I think problem in your timezone (looks like UTC+02:00)
You have to send time in UNIX time without any timezone offset
