How do I post a transaction bundle in python?

settings = {
    'app_id': 'my_web_app',
    'api_base': 'http://fhirtest.b12x.org/r3'
}
smart = client.FHIRClient(settings=settings)
response = bundle.create(smart.server)

will POST to the bundle endpoint, but not to the base url where it needs to go for transactions to be processed.

Indeed, create always posts to base_url + resource_type, you'll need to do that manually. Look at def create(...) in fhirabstractresource.py (9 lines of code, around line 114) and create a method that does the same, expect using None instead of self.relativeBase() in the post_json call.

*except

Thanks! @Pascal Pfiffner

If we created a new method, say "create_bundle", then it would be accessible to all resource models even though it should only be used with a bundle resource. Does checking to see if it's a Bundle transaction make sense instead of creating a new method? Adding the following lines of code to the create method works.

    base_url = self.relativeBase()
    if(self.resource_type == "Bundle"
       and self.type == "transaction"):
        base_url = None

should also test for self.type == "batch" which should also be processed
