And the problem is? If you want to update the data you have 2 options. Use get of update

Arturo

Get or update

Orack

And the problem is? If you want to update the data you have 2 options. Use get of update

There is only a few difference between two and 3. Ive created 2 project in Django 3 within the past one month. I only encountered issues with DRF because of six location and a few issues. Though I modified DRF to work in 3. But won't use it in production until DRF foundation release their upgrade

Orack

u mean obj = A.objects.get(userid=userid) obj.data = "some_new_value" obj.save()?

using google is the first thing to do, you can ask for specific doubts here to this group, giving enough context of what you're trying to do, what you've done in order to solve your issues, and show code so people can easily help you

Arturo

You can use the same. But I prefer use different url. You can use with put method instant of post

Find out your requirements, Google for information and tools Read and research further Plan your design and revise Get to work, once you hit a block, brute force until you get exhausted. If by then know solutions, ask questions based on your issues with code on pastebin, what you've tried and what you want to achieve. Will be glad to help. Thank you.
