objective c - Restkit: Post Json Array and Map response to Managed Objects -


here setup, post list of objects in json server , got updated results mapped core data , updated.

-- post boday --

{ "memberid": "1000000", "contacts": [ { "phonenumber": "+12233333333", "firstname": "john", "lastname": "h" }, { "phonenumber": "+12244444444", "firstname": "mary", "lastname": "k" } ] }

-- post response --

{ "contacts": [ { "phonenumber": "+12233333333", "firstname": "john", "lastname": "k", "ismember": "yes" }, { "phonenumber": "+12244444444", "firstname": "mary", "lastname": "k", "ismember": "no" } ] }

i found thread discusses similar case. restkit: how 1 post array of objects?

this setup.

-- shcontact.h --

@interface shcontact : nsmanagedobject {} @property (nonatomic, strong) nsstring* phonenumber; @property (nonatomic, strong) nsstring* firstname; @property (nonatomic, strong) nsstring* lastname; @property (nonatomic, strong) nsnumber* ismember; @end

-- shcontactpost.m --

#import "shcontactpost.h" @implementation shcontactpost @synthesize contacts; @synthesize memberid; - (nsarray*)contacts { return <list-of-shcontact>; } - (nsstring *)memberid { return @"my-member-id"; } @end

-- rk mapping --

// setup our object mappings shcontact rkmanagedobjectmapping* contactmapping = [rkmanagedobjectmapping mappingforclass:[shcontact class] inmanagedobjectstore:objectmanager.objectstore]; contactmapping.primarykeyattribute = @"phonenumber"; [contactmapping mapattributes:@"phonenumber", @"firstname", @"lastname", @"ismember", nil]; [objectmanager.mappingprovider setobjectmapping:contactmapping forkeypath:@"contacts"]; [[objectmanager mappingprovider] setserializationmapping:[contactmapping inversemapping] forclass:[shcontact class]]; rkobjectmapping *cpostmapping = [rkobjectmapping mappingforclass:[shcontactpost class]]; [cpostmapping mapkeypath:@"contacts" torelationship:@"contacts" withmapping:contactmapping]; [cpostmapping mapattributes:@"memberid", nil]; [objectmanager.mappingprovider setserializationmapping:[cpostmapping inversemapping] forclass:[shcontactpost class]]; [objectmanager.router routeclass:[shcontactpost class] toresourcepath:@"/contacts" formethod:rkrequestmethodpost]; objectmanager.serializationmimetype = rkmimetypejson;

-- post server --

shcontactpost *post = [[shcontactpost alloc] init]; rkobjectmanager* manager = [rkobjectmanager sharedmanager]; [manager postobject:post delegate:self];

server post , response successful. however, reskit not able map result list of shcontact objects. exception. missing something?

restkit.network:rkobjectloader.m:222 encountered errors during mapping: cannot map collection of objects onto non-mutable collection. unexpected destination object type 'shcontactpost'

update: changed make work me.

-- rk mapping --

// setup our object mappings shcontact rkmanagedobjectmapping* contactmapping = [rkmanagedobjectmapping mappingforclass:[shcontact class] inmanagedobjectstore:objectmanager.objectstore]; contactmapping.primarykeyattribute = @"phonenumber"; [contactmapping mapattributes:@"phonenumber", @"firstname", @"lastname", @"ismember", nil]; [objectmanager.mappingprovider addobjectmapping:contactmapping];

-- post server --

shcontactpost *post = [[shcontactpost alloc] init]; rkobjectmanager* manager = [rkobjectmanager sharedmanager]; rkobjectmapping* responsemapping = [manager.mappingprovider objectmappingforclass:[shcontact class]]; [manager postobject:post usingblock:^(rkobjectloader *loader) { loader.delegate = self; loader.targetobject = nil; responsemapping.rootkeypath = @"contacts"; loader.objectmapping = responsemapping; }];

loader.targetobject needs set nil, otherwise, won't work.

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
