Re: django / tastypie - how to exclude a resource attribute from obj_create, but keep it for listing

Hi Eugene,

Would it work to something like this in your obj_create?

bundle.data.pop('blueprint', None)

 When I use curl to POST: 

 curl -i -H "Content-Type: application/json" -X POST -d 
 @wkl.json  http://localhost:8000/api/workload/

 where wkl.json is:

 { "name":"w 5", "description":"w 5 desc" }


 I get this error:

 AttributeError: 'Workload' object has no attribute 'blueprint'

 I do need to have this attribute, so I can list all child workloads for a given blueprint 
 like this:  GET /api/workload/?blueprint=1

 but I need to exclude this 'blueprint' attribute from participating in the obj_create

 What is the proper place and syntax to do this?
