Django download files
Question
I'm working in a project which I want display many images in a website, so the user can download them. I can display the name of the images, but the download isn't working. I think it's something on my views, because I'm using Django, and getting the error the current path ... didn't match any of this . The name of the directory with the images is Images , and has others sub directories inside, and inside those sub directories, there are the images.
My views page, I think the problem is here, in the download function:
from django.shortcuts import render
import os
from django.http import HttpResponse, Http404
from django.http import FileResponse
def index(request):
flPath = os.listdir('Images/')
fl4 = []
for root, dirs, files in os.walk("Images/", topdown=False):
for name in files:
fl4.append(os.path.join(root, name))
for name in dirs:
fl4.append(os.path.join(root, name))
return render(request, 'catalog/index.html', {'path': fl4})
def downloadImage(request, path):
imagePath = 'Images/'
file_path = os.path.join(imagePath, path)
if os.path.exists(file_path):
with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type='text/csv')
response['Content-Disposition'] = 'inline; filename=' + file_path
return response
raise Http404
My app urls, catalog.urls:
from django.urls import path, include
from .views import *
urlpatterns = [
path('', index, name='index'),
path('Images/<str:path>', downloadImage, name='download'),
]
My project urls, SiteSmu4Img:
from django.contrib import admin
from django.urls import path, include
from django.views.generic import RedirectView
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('Images/', include('catalog.urls')),
path('', include('catalog.urls')),
]
My index.html:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/html">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% if path %}
<table>
<tr>
<th>Images</th>
<th>Download</th>
</tr>
{% for i in path %}
<tr>
<td>{{ i }}</td>
<td><a href="{{ i }}">download</a></td>
</tr>
<img src="Images/{{ i }}">
{% endfor %}
</table>
{% endif %}
</body>
</html>
The stack trace:

The issue in you code is:
catalog.urls: path('Images/', include('catalog.urls')),
SiteSmu4Img: path('Images/<str:path>', downloadImage, name='download'),
so, in total the path should be like Images/Images/<str:path> , but in the template you have just:
<img src="Images/{{ i }}">
Correct this issue first, then show the stacktrace if the solution won't fix all the errors.
Add another Images into the template for the beginning and add the leading slash in the path:
<img src="/Images/Images/{{ i }}">

you can't get images or any static file directly.
Django finds resources of the static folder or media folder.
add images in static folder and add STATIC_FOLDER , STATIC_URL values in settings.py
if you want to add images through the website, set MEDIA_ROOT , MEDIA_URL in settings.py
add a URL in urls.py . now you can access images through Django.
