Question

我正在尝试将图像保存到媒体根文件夹，该文件夹已在媒体文件夹中命名为图片。这是我的代码，我希望每当我的函数制作屏幕截图时，都应将屏幕截图保存在媒体根文件夹中。

from django.shortcuts import render
from django.http import HttpResponse
from django.shortcuts import get_object_or_404,render,redirect
import time 
import random
from django.db import models
import pyautogui
import sys
from shots.models import pictures
from .models import pictures
from shots.forms.forms import DocumentForm

def button(request):
    import pyautogui
    myScreenshot = pyautogui.screenshot()
    storage=pictures.pictures2
    myScreenshot.save(storage)

    return render(request,'index.html')

def output(request):
    return HttpResponse("""Hello, world. You're at the polls index.
    your Screenshot should start now""")

这是我的 models.py ：

from django.db import models
import random


class pictures(models.Model):
    pub_date = models.DateTimeField('date published')
    pictures2 = models.ImageField(upload_to='pictures')

您会发现this answer有帮助。

FileField和ImageField的文件是相对于settings.MEDIA_ROOT上传的，并且应该可以通过附加到settings.MEDIA_URL的相同相对文件名来访问。

话虽如此，如果您命名settings.MEDIA_ROOT = 'pictures'并告诉模型到upload_to='pictures'，那么django上载的文件最终将位于：

**/pictures/pictures/myScreenshot.png**

import pyautogui

from django.shortcuts import render
from django.http import HttpResponse
from django.conf import settings

from .models import pictures


def button(request):
    myScreenshot = pyautogui.screenshot()

    """ 
    The path and filename are relative o where you execute this script.
    """
    filename = settings.MEDIA_ROOT+'pictures/myScreenshot.png'
    myScreenshot.save(filename)

    return render(request,'index.html')

您的models.py：

from django.db import models
import random


class pictures(models.Model):
    pub_date = models.DateTimeField('date published')
    pictures2 = models.ImageField(upload_to='pictures')

如何从python将图像保存在Django媒体根存储中
