Django 在 pythonanywere 上的部署

Question

我在 pythonanywhere 上部署了 django 应用程序 但我发现相对路径有问题。

这个应用程序可以上传并保存2个文件在一个目录中 我的代码实际上是：

from django.shortcuts import render
from django.core.files.storage import FileSystemStorage
import pandas as pd
import datetime
from datetime import datetime as td
import os
from collections import defaultdict

def home(request):
#upload file and save it in media folder
    if request.method == 'POST':
        uploaded_file = request.FILES['document']
        uploaded_file2 = request.FILES['document2']

        if uploaded_file.name.endswith('.xls'):

            savefile = FileSystemStorage()
#save files
            name = savefile.save(uploaded_file.name, uploaded_file)
            name2 = savefile.save(uploaded_file2.name, uploaded_file2)

            d = os.getcwd()
            file_directory = d+'\\media\\'+name
            file_directory2 = d+'\\media\\'+name2

            results =results1(file_directory,file_directory2)

我给出了这个错误

FileNotFoundError at /
[Errno 2] No such file or directory: '\\Listing


/home/VIRAD/Django1/viruss/views.py, line 26, in home
            results,output_df,new =results1(file_directory,file_directory2) 

urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include("v.urls")),

 ]
if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Answer 1

将这些行更改为此

file_directory = d+'\\media\\'+name
file_directory2 = d+'\\media\\'+name2

，

from django.conf import settings

file_directory = f"{d}{settings.MEDIA_URL}{name}"
file_directory2 = f"{d}{settings.MEDIA_URL}{name2}"

并确保您已在 settings.py 文件中指定 MEDIA_URL
像这样

MEDIA_URL = '/media/'

并将其添加到您的项目中（其中存在 settings.py） urls.py

from django.conf import settings
从 django.conf.urls.static 导入静态

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Answer 2

看来是路径问题。
我们的代码看起来像：

from pathlib import Path  # We use the *pathlib* library
BASE_DIR = Path().resolve()
NEED_DIR = os.path.join(BASE_DIR, 'fixtures')

Тогда ваш код будет выглядеть：

d = os.getcwd()
file_directory = os.path.join(d, 'media', name1)
file_directory2 = os.path.join(d, 'media', name2)
