Send an authenticated POST request to tastypie

Question

I am trying to send an ApiKey-autheticated POST request to a tastypie API

my Model:

class Thing(models.Model):
    name = models.TextField()

    def __unicode__(self):
        return u'%s'%self.name

my ModelResource

class ThingResource(ModelResource):
    class Meta:
        queryset = Thing.objects.all()
        resource_name="thing"
        authentication = ApiKeyAuthentication()
        authorization = DjangoAuthorization()

my urls.py

from django.conf.urls.defaults import patterns, include, url

from tastypie.api import Api
from myapp.api import ThingResource

mobile_api = Api(api_name='mobile')
mobile_api.register(ThingResource())

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
    url(r'^admin/', include(admin.site.urls)),

    (r'^api/', include(mobile_api.urls)),
)

and my cURL command

curl --dump-header - -H "Accept: application/json" -H "Content-Type: application/json"  -d"username=vikingosegundo" -d"api_key=12345" -X POST --data "{\"name\":\"arrrg\"}" http://localhost:8000/api/mobile/thing/

the Response

{"error_message": "No JSON object could be decoded", 
 "traceback": "Traceback (most recent call last):\n\n  
    File \"/Users/vikingosegundo/Coding/Project/serverside/mysite/tastypie/resources.py\", line 178, in wrapper\n    response = callback(request, *args, **kwargs)\n\n

    ValueError: No JSON object could be decoded\n"
}

What am I doing wrong? How do I point tastypie to the json object? The auth+auth seem to be working.

Using the -d and --data with curl is mangling the POSTed data.

Including the username and api_key params in the GET should solve this, like so:

    curl --dump-header - -H "Accept: application/json"\
    -H "Content-Type: application/json"  -X POST\
    --data "{\"name\":\"arrrg\"}"\
    "http://localhost:8000/api/mobile/thing/?username=vikingosegundo&api_key=12345"
