RestKit Object Mapping relationships with foreign keys

Question

Can RestKit connect a relationship without storing the foreign key as an attribute, i.e., directly from the keypath in the JSON?

In particular, I\'ve got a Job has_many

Answer 1

I would make JobId a transient value in core data, and write a custom set and get for it.

The set would set the relationship to self.job=methodToReturnObjectMatchingJobId (this would be used by rest kit)

The get would return self.job.identifier

If you are not using mogenerator, I would suggest you have a look at it for all your core data needs.

Below is sample code of how i did it:

-(void) setClaimId:(NSNumber *)claimId{
     Claim *propertyClaim=[Claim listItemFromId:[claimId intValue] withContext:self.managedObjectContext]; 

    self.claim=propertyClaim; 
}
-(NSNumber*) claimId{

  return self.claim.referenceId;
}

where listItemFromId is a simple query that returns the object based on the id.
