I’m new to Django and I’m having trouble handling form-data and raw data in PUT requests. I need to update records of a Person model via a PUT request. The Person model has several fields including fname, sname, age, and gender, all of which are required.
I have a view to handle the PUT request, and I’m trying to handle both JSON and form-data formats in the request body.
However, when I send a PUT request via Postman, I encounter the following error:
Exception Type: IntegrityError Exception Value: NOT NULL constraint failed: api_person.fname
To handle different request formats, I first attempt to parse the request body as JSON. If JSON parsing fails, I fall back to handling form-data. Here’s the relevant part of my view:
`try:
# Attempt to parse request body as JSON
data = json.loads(request.body)
fname = data.get(‘fname’)
sname = data.get(‘sname’)
age = data.get(‘age’)
gender = data.get(‘gender’)
except json.JSONDecodeError:
# Handle form-data if JSON parsing fails
fname = request.POST.get(‘fname’)
sname = request.POST.get(‘sname’)
age = request.POST.get(‘age’)
gender = request.POST.get(‘gender’)
# Update person object with received data
person.fname = fname
person.sname = sname
person.age = age
person.gender = gender
person.save()`
I expected this approach to handle both request formats seamlessly and update the Person record correctly. However, I encountered a NOT NULL constraint failed: api_person.fname error, which indicates that the fname field is missing or empty.
Despite adding print statements and validation checks, I couldn’t figure out why fname is still missing. Any insights or suggestions to resolve this issue would be greatly appreciated!
