RawPostDataException
You cannot access body after reading from request's data stream

Way how you read request body kill Django-Stripe integration
https://github.com/dj-stripe/dj-stripe/blob/3eafe287ac93d94f2615ff8a5b53ddf7e5e9e46c/djstripe/models/webhooks.py#L81-85

I'm sorry, I can't reproduce this issue. Could you open a new issue, with a traceback?

It's somewhat difficult to understand why using sentry with django_rest_framework does not upload request bodies out of the box. There were a few scattered SO and github threads about the problem but the few that I found refer to the older sentry client. I managed to track down the problem and wanted to share my results.

1. DRF uses its own json parser and calls request.read directly, without storing the result on django's request._body
2. Sentry attempts to read from django's request.body, which then errors because the stream has already been read and not assigned to request._body

Here are relevant parts of the code that I found:

https://github.com/encode/django-rest-framework/blob/3.9.0/rest_framework/parsers.py#L68

https://github.com/django/django/blob/2.1.5/django/http/request.py#L283

One workaround is to do something silly like this:

@api_view(['POST'])
def my_view(request):
    request.body # side effect of storing the whole request body in memory on request._request._body
    do_something(request.data)

I put up a repo demonstrating this.

It would be significantly better imo if there was a separate integration for DjangoRestFramework that simply read from request.data directly and let DRF do the parsing, as you suggested when you opened this thread.

If that work will be accepted I can tackle it and put up a pr.

Hi, I've also faced this issue when using DRF 3.9.0 and sentry-sdk 0.7.8 (0.7.4 also has this). With new unified sdk request bodies aren't sent to Sentry UI.

I was able to track it down to the place where issue occurs.

When extracting data from request, sdk tries to get body here, but it's impossible due to the You cannot access body after reading from request's data stream error. It is raised when sdk is trying to read self.request.body inside the called function in django integration.

@cwmoo740 I'm very sorry I dropped the ball on this. Your investigation is very complete and I will fix this in the next release.

I think the primary confusion for me was that request.body does not get populated when request.data is accessed. I assumed that implementing access to request.data was not essential for being able to capture the request body of DRF apps.

0.7.10 was released which should fix this

This is happening on 2.0.1
