python - add() argument after * must be a sequence, not Result -

models.py

class result(models.model):              host = models.charfield(max_length=200)             type = models.charfield(max_length=1, choices=type_choices)             active = models.booleanfield(default=false)             current = models.floatfield()             value = models.floatfield()             notify = models.booleanfield(default=false)             info = models.textfield()             test = models.foreignkey('test', related_name='result')             group = models.foreignkey(group, blank=true, null=true, default=none, related_name='result')             timestamp = models.datetimefield()             created = models.datetimefield(auto_now=true) 

my resource:

class resultresource(modelresource):         test = fields.foreignkey(testresource, 'test', full=true, related_name='result')         group = fields.foreignkey(groupresource, 'group', full=true, related_name='result')          class meta:             queryset = result.objects.all()             list_allowed_methods = ['get', 'post']             resource_name = 'result'             fields = ['host', 'type', 'current', 'value', 'notify', 'info', 'timestamp']             include_resource_uri = false             excludes = ['id', 'group']             authentication = authentication()             authorization = authorization() 

i want create new resource via post request.

this json:

{     "current": 26.74,     "host": "host 1",     "info": "info text",     "notify": true,     "test": "/api/v1/test/1/",     "timestamp": "2010-11-10t03:07:43",     "type": "w",     "value": 10,     "group" : "/api/v1/group/1/" } 

the test , group exist.

but error: "error_message": "add() argument after * must sequence, not result".

i read tastypie has problems many2many fields changed, testing, many2many field foreignkey field. doesn't solve problem.
