How to solve MultiValueDictKeyError

[Kayode Odeyemi]

Hello friends,

I don't know why Django is so unstable.

Before restarting my computer everything works fine. Django could parse a simple
POST request without complaining KeyError.

I'm simply making a POST request like this:

curl -v -H "Content-Type: application/json" -A 'Mozilla' -X POST --data 'fees={"fees":{"status":"pending","timeout":5}, "hostel":{"status":"pending","timeout": 3}}' http://127.0.0.1:8000/api/transaction/add/ > post_data.txt

I also have it in valid dict format like this:

curl -v -H "Content-Type: application/json" -X POST --data 'fees={"fees":[("status","pending"),("timeout",5)], "hostel":[("status","pending"),("timeout", 3)]' http://127.0.0.1:8000/api/transaction/add/ > post_data.txt

This worked throughout yesterday. Just hoping to continue from where I left off, and I can't progress as I would love to.

The problem is simply understandable, but why didn't Django say this when I worked on it yesterday. This is not fair Djanjo. It is not!

Somebody please help me.

Thanks

Hi,

please post in django-users, this mailinglist is about the development of django itself, not about enduser problems.
