I'm using <a href="https://github.com/magicalpanda/MagicalRecord" rel="nofollow">Magical Record</a> for database with Xcode. I have two entities, one is named 'task' and the other is 'comment', I want to make a relationship so that one task has an array of comments when I query for a task, is it possible, I am new with magical record, hope I made the problem understandable. Thanks. edit: hey, thanks for your help, i used this code to put the comments in a task: <pre><code>NSManagedObjectContext *localContext = [NSManagedObjectContext MR_defaultContext]; TarefaMR *task = [TarefaMR MR_createInContext:localContext]; task. //... for (NSDictionary *comment in [tarefa objectForKey:@"comments"]) { NSManagedObjectContext *localContext3 = [NSManagedObjectContext MR_defaultContext]; ComentarioMR *comment = [ComentarioMR MR_createInContext:localContext3]; [localContext3 MR_saveToPersistentStoreAndWait]; [task addComentariosObject:comment]; } [localContext MR_saveToPersistentStoreAndWait]; </code></pre> but now i try to access it and i cant seem to get the data from the comments from a task, code I used : <pre><code>for (TarefaMR *tarefa in [TarefaMR MR_findAll];) { NSLog(@"tarefa.comentarios %@",tarefa.comentarios); } </code></pre> I get a <blockquote> tarefa.comentarios Relationship 'comentarios' fault on managed object : comentarios = ; </blockquote> I already tried to loop tarefa.comentarios in a for, but dont seem to get anything, if i query the comments database, the objects are there. Then for I tried to use: <pre><code>for (ComentarioMR *comment in tarefa.comentarios) { NSLog(@"comment listHeader %@", comment.listHeader); NSLog(@"comment listText %@", comment.listText); } </code></pre> how can i get the comments of the task?

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.
