QUESTION
hey guys i am learning react js and I have an update form to update book info. I am using django rest api for endpoints. I have a working form where I can upload files and do all those stuffs but I am not able to show the image which is already there in the template, Here I have a book cover image, which is already there in the database, it should be showing in the front-end and when I change the image, the new one should show, how can I add that feature here, I tried and consoling out this is showing the url, but the image isn't getting displayed.
From the network tab,
The problem I think is
Request URL:http://localhost:3000/media/book/book_sample/pride_in_nat.png
request url since the image gets displayed if the url is localhost:8000
instead of localhost:3000
as it is where the django server backend runs. So, how can I change that?
This is the code.

ANSWER
Answered 2020-Nov-04 at 16:31I would advise this as being the best solution and I highly would recommend this even though I have not worked heavily with Django.
I know with Django you can store files in media files as configured in your settings.py, as good and convenient that is I guess but the best solution in my understanding for managing files is dealing with a 3rd party like cloudinary(Very common when working with Node using 3rd party software's to manage files)
So the flow behind:
- Make an account on cloudinary(Do not worry it's completely free but can upgrade)
- When you want to save a file to DB you first interact with cloudinary with Django.
- Once Django is done cloudinary Api will bring back a url of your image.
- Then what you only have to do now is now save that link given in your database
Now with your Django Model
- In the place where you had image as a "FileField" now you can safely convert to "CharField" or whatever that means text/string in django kind of forgot
- Then now in your React app that should work

Answered 2020-Jan-17 at 16:16It is perfectly fine to use __init__.py
to compress your namespace. Use __all__
to clearly define that imported names are meant for export.
