[英]How to execute a python script from django management commands?
我正在嘗試執行不在Django Project目錄中的python腳本...例如,這是我使用以下命令調用的管理類:
我需要以ROOT身份運行它,因為它需要訪問我的樹莓派上的GPIO引腳。 (並且我得到另一個錯誤)
(env) sudo python manage.py bubbles
調用此腳本的文件:execfile('/ home / pi / rpi / bubbles.py')
# /home/pi/DjangoProjects/RaspberryPi/graphics/management/commands
from django.core.management.base import BaseCommand, CommandError
from django.core.management.base import BaseCommand
from graphics.models import Graphic
class Command(BaseCommand):
help = "My test command"
def handle(self, *args, **options):
execfile('/home/pi/rpi/bubbles.py')
我得到這個錯誤
Traceback (most recent call last):
File "manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named django.core.management
因此,我猜測這是我的虛擬環境存在的問題,沒有辦法在虛擬環境范圍之外執行腳本嗎? 有沒有更好的方法使用django命令或其他方法執行此腳本。 我有任何意義嗎?
我正在嘗試調用的python腳本:
#!/usr/bin/env python
import Image
import ImageDraw
import time
from rgbmatrix import Adafruit_RGBmatrix
# Rows and chain length are both required parameters:
matrix = Adafruit_RGBmatrix(16, 2)
# Bitmap example w/graphics prims
image = Image.new("1", (16, 64)) # Can be larger than matrix if wanted!!
draw = ImageDraw.Draw(image) # Declare Draw instance before prims
# 24-bit RGB scrolling example.
# The adafruit.png image has a couple columns of black pixels at
# the right edge, so erasing after the scrolled image isn't necessary.
while True:
matrix.Clear()
image = Image.open("bubbles.png")
image.load()
for n in range(64, -image.size[0], -1):
matrix.SetImage(image.im.id, n, 1)
time.sleep(0.025)
matrix.Clear()
也許我正在以錯誤的方式進行此操作,我只是在學習將Web框架與樹莓派相結合。
在您的bubbles.py中 ,而不是這樣做
def handle(self, *args, **options):
execfile('/home/pi/rpi/bubbles.py')
嘗試這個
def handle(self, *args, **options):
execfile('PATH_TO_YOUR_ENV/bin/python /home/pi/rpi/bubbles.py')
