Implemented Embedded Model properties.With this setup a Model property can be embedded instead of referenced by ID, If an existing Model is embedded, it keeps a referenceID to the original Model. See 6b2e8c87219ea25aaa65f38c270165abcfe1b924 and the new unit tests for more information. |

Could you please use |
CouchUser* user = [_server userWithName:@"Alice"]; user.password = @"secret"; // will be hashed on the server // set some additional properties [user setValue:@"Alice" ofProperty:@"firstname"]; [user setValue:@"Wonderland" ofProperty:@"lastname"]; if ([[user save] wait]) NSLog(@"Saved: %@", user); CouchSecurity* security = [_db security]; security.readerNames = [NSArray arrayWithObjects:@"bob", nil]; security.adminRoles = [NSArray arrayWithObjects:@"boss", nil]; // add an admin user [security addObject:user.name forProperty:kSecurityAdminNamesKey]; if ([security update]) NSLog(@"Saved: %@", security);
With this setup a Model property can be embedded instead of referenced by ID,
making it easy to develop a nested model structure. The next logical step is
to enable this for NSArray properties - allowing embedding and referencing of
other CouchModel objects.
If an existing Model is embedded, it keeps a referenceID to the original Model.
There are various ways to control the embedding behaviour, using hook methods:
+ (id) embeddedModelForDocument:(CouchDocument *)document
parent:(CouchModel*)parent
property:(NSString *)property;
- (BOOL) isEmbedableModelProperty: (NSString*)property;
- (BOOL) isEmbedableIn: (CouchModel*)parent forProperty:(NSString*)property;
- (void) didEmbedIn: (CouchModel*)parent forProperty:(NSString*)property;
- (NSDictionary*) embeddedPropertiesToSave;
Example of creating a new embedded model:
Student* alice = [self createModelWithName: @"Alice" grade: 9];
Student* buddy = [alice embedModelForProperty:@"buddy"];
buddy.name = @"Bob";
[alice save];
if (alice.buddy.name == bob.name) NSLog(@"Buddies");
Example of embedding an existing model:
Student* alice = [self createModelWithName: @"Alice" grade: 9];
Student* bob = [self createModelWithName: @"Bob" grade: 7];
[alice embedModel:bob forProperty:@"buddy"];
[alice save];
if (alice.buddy.name == bob.name) {
NSLog(@"Buddies - referenceID: %@", alice.buddy.referenceID);
}
