Thank you for putting together this tutorial. However 18MB of sample images is unnecessary. Not a big deal, just a suggestion.

after integrating the project image is not uploading ... Giving error as image uploading failed

I have 2 question hope you make me clear.

1. I follow your instruction to make a relationship to User Model. User can upload his / her avatar to album photo and have a CURRENT PHOTO like Facebook. But I've been failed. How can I make a field: Current Photo with your instruction.
2. If I use Sorl Thumbnail. Is it better than Pillow package you make?

Environment:

Python 3.6.0 (v3.6.0:41df79263a11, Dec 22 2016, 17:23:13) 

Django==2.1.7
django-filter==2.1.0
djangorestframework==3.9.1
Markdown==3.0.1
Pillow==5.4.1
pytz==2018.9

Error in step 3 when adding the API urls to the backend for browsing:

File "/.../django-rest-imageupload-example/venv/lib/python3.6/site-packages/django/urls/conf.py", line 39, in include
    'Specifying a namespace in include() without providing an app_name '
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.

ref: https://code.djangoproject.com/ticket/28691

fix is to add the line app_name="imageupload_rest" to imageupload_rest/urls.py

from django.conf.urls import url, include
from rest_framework import routers

app_name="imageupload_rest"

router = routers.DefaultRouter()

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    url(r'^', include(router.urls)),
]

I have cloned and am using the framework.
I am not able to figure out how to upload an image via a POST request.

Is it necessary for to create directory first?

below my tracetack.:

This is not an issue, but I am trying to extend this project by adding few more functionalities to it like:
1)I want to add one more button for every image called segment(see image)
2)on clicking this button that corresponding image should be passed to my view(python script).this python script returns four values(x,y,w,h) and i want to render these coordinates as a bounding box on the corresponding image.

Can you point me to the right resources to learn about this and implement it.

In the years that have passed since this tutorial was created it looks like Node module version rot has set in.

After a bit of tinkering these are the version of the node modules that are working for me:

npm install [email protected] [email protected] [email protected] [email protected] [email protected] [email protected]

Hi, I've followed along and want to thank you so much. Did you ever create chapter 3?
Cheers
