F objects are no longer deepcopy-able

[ris]

I suspect the culprit is commit 3a66035107a640c4905f0a5f247a45f32dbe16d7 "Removed F.deepcopy()" because apparently "The method didn't change standard deepcopy in any way.".

Well, in 1.7.0:

>>> from django.db.models import F
>>> from copy import deepcopy
>>> f = F ( "something__some_field" )
>>> f.name
'something__some_field'
>>> g = deepcopy ( f )
>>> g.name
AttributeError: 'F' object has no attribute 'name'

Paste back in the same deepcopy method removed in 3a66035107a640c4905f0a5f247a45f32dbe16d7, and:

>>> from django.db.models import F
>>> from copy import deepcopy
>>> f = F ( "something__some_field" )
>>> f.name
'something__some_field'
>>> g = deepcopy ( f )
>>> g.name
'something__some_field'

Tadaa!

Can we have it back please?

Hi,

I can indeed reproduce your issue and bisecting it points to 3a66035107a640c4905f0a5f247a45f32dbe16d7 as you suspected.

We should probably add the method back but also add some tests to make sure we don't break that again.

Thanks.
