Correct, this was a bad example, and in this case I'd tend to agree and that type of relationship does work. Replacing "Country" with "Thing", and considering that each person has a "Thing" is closer to what I was thinking. "Things" know nothing about people, and are just things. Each person will always have just one thing, so we don't need the flexibility of a join table to associate an arbitrary number of Things with a person. A belongsTo relationship will do the job but seems incorrect as in this case a Person has a Thing, and a Person does not belong to a Thing. What is the case though is that the actual value in the Thing column of a Person does belong to Things, and if we consider that then it does make sense. So whilst Person as a whole does not belong to Thing, the Thing *value* of a Person does belong to Thing. Another example would be Colour, where all manner of models might have Colour as an attribute, but the models would not belong to colour. > I wrote a bit on understanding the practical differences between > relationships here:http://bennerweb.com/node/16 This is a great article, although you show why there is the confusion when you write "each movie has one director" but then model that relationship with belongsTo and not hasOne :) Aside from the fact that belongsTo would work and hasOne wouldn't, as a movie is the creative work of a director it would be fair enough to consider that a movie belongs to a director, but in some cases I feel that hasOne would be the clearer and more natural choice as this is how we would explain the model to someone. It's evidently unnecessary for an enhancement to hasOne, however for the sake of expressiveness, being able to use hasOne or perhaps an "isA" concept might be clearer. Thanks again for the helpful reply though. Nick --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Cake PHP" group.
