    <p>I am trying to use example RKCatalog from new RestKit 0.9.3. In RKRelationshipMappingExample creators have forgotten to add connection code between Task and User, but even after adding it doesn't work correctly.</p> <pre><code>{"project": { "id": 123, "name": "Produce RestKit Sample Code", "description": "We need more sample code!", "user": { "id": 1, "name": "Blake Watters", "email": "blake@twotoasters.com" }, "tasks": [ {"id": 1, "name": "Identify samples to write", "assigned_user_id": 1}, {"id": 2, "name": "Write the code", "assigned_user_id": 1}, {"id": 3, "name": "Push to Github", "assigned_user_id": 1}, {"id": 4, "name": "Update the mailing list", "assigned_user_id": 1} ] }} </code></pre> <hr> <pre><code>[taskMapping connectRelationship:@"assignedUser" withObjectForPrimaryKeyAttribute:@"assignedUserID"]; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:gRKCatalogBaseURL]; objectManager.objectStore = [RKManagedObjectStore objectStoreWithStoreFilename:@"RKRelationshipMappingExample.sqlite"]; RKManagedObjectMapping* taskMapping = [RKManagedObjectMapping mappingForClass:[Task class]]; [taskMapping mapKeyPath:@"id" toAttribute:@"taskID"]; [taskMapping setPrimaryKeyAttribute:@"taskID"]; [taskMapping mapKeyPath:@"name" toAttribute:@"name"]; [taskMapping mapKeyPath:@"assigned_user_id" toAttribute:@"assignedUserID"]; [taskMapping connectRelationship:@"assignedUser" withObjectForPrimaryKeyAttribute:@"assignedUserID"]; [objectManager.mappingProvider setMapping:taskMapping forKeyPath:@"task"]; RKManagedObjectMapping* userMapping = [RKManagedObjectMapping mappingForClass:[User class]]; [userMapping mapAttributes:@"name", @"email", nil]; [userMapping mapKeyPath:@"id" toAttribute:@"userID"]; [userMapping setPrimaryKeyAttribute:@"userID"]; [userMapping mapRelationship:@"tasks" withMapping:taskMapping]; [objectManager.mappingProvider setMapping:userMapping forKeyPath:@"user"]; // NOTE - Project is not backed by Core Data RKObjectMapping* projectMapping = [RKObjectMapping mappingForClass:[Project class]]; [projectMapping mapKeyPath:@"id" toAttribute:@"projectID"]; [projectMapping mapAttributes:@"name", @"description", nil]; [projectMapping mapRelationship:@"user" withMapping:userMapping]; [projectMapping mapRelationship:@"tasks" withMapping:taskMapping]; [objectManager.mappingProvider setMapping:projectMapping forKeyPath:@"project"]; } return self; } </code></pre> <p>Am i doing everything alright? -- it doesn't connect task to user by user's ID.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
