i have issue put() not appear work if access model class indexed member of query directly; however, when explicitly extract class query seems work fine. why this? this code works: class record: field = db.stringproperty() rs = record.all().filter('name = ', name_str) if rs.count() == 1: # assume 1 record in return... r = rs[0] r.field = some_value r.put() and code doesn't (and not raise errors) class record: field = db.stringproperty() rs = record.all().filter('name = ', name_str) if rs.count() == 1: # assume 1 record in return... rs[0].field = some_value rs[0].put() every time index query this, performs query on again, fetches relevant result, decodes it, , returns you. in second snippet, modify 1 instance of entity, discard it, fetch , store (unmodified) second copy. generally, should avoid indexing queries - call .get() or .fetch() instead. for same reason, should avoid using .count() possible, since req...

we organize c++ project this: project/ lib1/ (first library) cmakelist.txt src/ lib1.c foo1.h build/ test/ (tests) cmakelist.txt test1.c test2.c lib2/ (second library) cmakelist.txt src/ cmakelist.txt os/ (os dependent code) cmakelist.txt win32/ xxx.c (win32 implementation) linux/ xxx.c (linux implementation) lib2.c foo2.h build/ include/ (shared/public headers) lib1/ lib.h (shared library header included apps) lib2/ lib.h (shared library header -"-) please, how write cmakelists.txt when lib2 should use link1 , when e.g. lib2 should portable (at least win32, linux...)? correction : if cmakelist.txt files not on places, pl...

i looking @ enums in wrong way want make sure have right theory in how use them. say have enum called colour. enum colour { red, green, blue }; red green , blue represented there 0-255 values. i'm trying initialize enum inside class shape , i'm not sure how go it. public class shape { colour colour; public shape(colour c) { //some attempts @ initialization. //treating object this.colour = c{ 255,255,255 }; //again this.colour.red = c.red this.colour.blue = c.blue this.colour.green = c.green colour.red = c.red? } } } i'm way off in terms of how i'm thinking enums. can give me pointers? in case, might want colour struct instead of enum. in c#, enums single-valued constructs, have 3 values (red, green, , blue). here's might instead: public struct colour { private byte red; private byte green...
