django - Access session in user model .save() - is possible access current session in user model .save()? pseudo code of want achieve: # users.models.py def save(self, *args, **kwargs): created = true if self.pk: created = false super(abstractuser, self).save(*args, **kwargs) # post-save if created: look_for_invite_in_session_and_register_if_found(self, session) seems wrong in architecture. shouldn't access request in models layer. work request must done in view. can this: user, created = abstractuser.objects.get_or_create(name=name) if created: look_for_invite_in_session_and_register_if_found(user, request.session) django session

ios - Back button still enabled when using popover in navigation bar - i have navigation controller master-detail view. detail view's navigation bar shows button on left , utilize uibarbuttonitem uipopovercontroller on right additional features. the right button correctly displays popover , pressing anywhere in view dismiss popover. my problem that, when popover active, navigation bar button still active. when user tries dismiss popover , presses on bar button, navigation controller unwinds master view , popover still visible! i tried placing popover on uibutton within view instead of navigation bar, , there behavior expected: if seek close popover pressing anywhere, on navigation button, closes popover (instead of calling button , unwinding master view) in either case, used story board create popover command dragging button (uibarbutton or uibutton) target view controller. is expected or doing wrong ?? thanks! when uipopovercontroller presented uinavig

mpi - Equivalent to MPI_Reduce_scatter but scattering among a subset of processors - is there mpi function equivalent mpi_reduce_scatter performs scattering among subset of processors? in case there no such function, efficient sequence of mpi calls? for clarity, suppose cut down operation sum. proc sendbuf 1 a1 | b1 2 a2 | b2 3 a3 | b3 4 a4 | b4 i want get proc recvbuf 1 2 b 3 4 where a = a1 + a2 + a3 + a4 , b = b1 + b2 + b3 + b4 . workarounds using 2 mpi_reduce . first reduces a s , has 1 root processor. sec reduces b s , has 2 root processor. however, becomes heavy when there many "letters" (and many processors). mpi_reduce_scatter , set recv_count[proc] different 0 if proc belongs subset of processors. however, when scattering message there n_proc square handshakes (most of them useless beacuse no message sent). i agree 2 mpi_reduce calls you're going if want mpi reductio

compiler construction - function definition in BNF C grammar - i'm reading this c bnf grammar. have next questions: is right it's <declarator> job parse syntax: id(int a, int b) (in <direct-declarator> ) , on arrays in parameters of function prototype/definition, etc; in <function-definition> , why <declarator> followed {<declaration>}* ? understood, create valid type name or storage class followed function header id(int a, int b) int . i'm sure isn't valid in c. missing? yes, <declarator> in grammar name of object beingness declared, plus arguments or array size (and pointer qualifiers of type). <declarator> not include base of operations type (return type function; element type array). note there 2 alternatives in <direct-declarator> , both of seem relevant functions: <direct-declarator> ( <parameter-type-list> ) <direct-declarator> ( {<identifier>}* ) first of these
