What's the syntax for a 'has_one' relationship?

[ghost]

I haven't found a way to do the 'has_one' relationship between two models. Is that possible? Thanks for any help.

Hm... Good question, I don't know why, but this feature is not implemented. But seems that implementation is very easy. For example:

@interface User : ActiveRecord
- (Project *)project;
@end

@implementation User

- (Project *)project
{
    return [[[Project lazyFetcher] where:@"user.id = %@", self.id] firstObject];
}

@end

setProject may looks very similar.

What about the Destroy Dependency?

The same as setProject, find record and remove it manually.

OK I found a way to do it. Thanks for the help and I'm really waiting to see the new version! P.S. The fetcher should be [where:@"'project'.'userId' = %@", self.id] (doesn't work otherwise)

Have a good day! :wink:

Yep, you're right!

Thank you :smile:
