Core Data-Linking one-to-many relationships

Question

I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

Answer 1

Need more clues.

• how are you creating the employee object?

• how are you fetching the department object?

• how are you updating the relationship?

• are you saving the context?

• are you checking for errors?
