django - Can a Tastypie filter be applied to a detail resource? -

i have django model sequence_number field incremented each time model instance updated:

class foo(models.model):     bar = models.textfield()     sequence_number = models.integerfield(default=0) 

i have implemented tastypie resource model, so:

class fooresource(modelresource):     class meta:         queryset = foo.objects.all()         resource_name = 'foo'         list_allowed_methods = ['get']         detail_allowed_methods = ['put', 'get'] 

so client user can request particular instance of foo using url this:

http://.../api/foo/123/ 

clients applications retain sequence_number know version of object holding.

i want implement filter on detail resource client can pass sequence_number holding server:

• if else has updated object since client's last request (so server sequence_number greater client sequence_number) resource should return updated object.
• if server sequence_number unchanged, resource should return nothing (or empty fields etc.).

i tried implement adding filter resource meta:

    filter = {         'sequence_number': ('gt',),     } 

and using following url:

http://.../api/foo/123/?sequence_number__gt=123 

but had no effect. did work when used list resource i.e.

http://.../api/foo/?sequence_number__gt=123 

so - possible configure tastypie accept filters on detail resources? if not, suggestions how should roll own solution (while still using tastypie)?
