но нифига не выходит( выдает ошибку
init() got an unexpected keyword argument 'CharField'
views.py:
import time
import datetime
import random
import serial
from qsstats import QuerySetStats
from grafic.models import Grafic
from django.views.generic.simple import direct_to_template

port='COM3',
baudrate=9600,
timeout=10,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
bytesize=serial.EIGHTBITS
)
# let's wait one second before reading output (let's give device time to answer)
time.sleep(1)
#str(out)
vhod = ser.read()
vhod = str(ord(vhod))
g = Grafic(radlvl=vhod)
g.save()
out = Grafic.objects.all()
start_date = ""
end_date = ""
qsstats = QuerySetStats(out, CharField='radlvl')
values = qsstats.time_series(start_date, end_date, interval='seconds')
#print ">>" + out
return direct_to_template(request,'index.html', {'out':out,'values': values})
