You're correct, the attribute is only in code and not in the model. Is it possible to filter by such an attribute?
Here is a verbose description of what I'm doing - State objects have Gallery objects. galleries() is the array of Gallery objects belonging to State. galleriesActive() is a filter on this array. hasOpeningPlusZeroDays() is a function returning a boolean value based on the count of a filter on galleriesActive(). I'm trying to ask my object if it has any galleries meeting a certain criteria. "Does this state have any galleries opening today?" My functions are working well for providing me with the necessary info but it doesn't allow me to search on it. Do I need to use another method to accomplish this? many thanks, matt On 9/8/06, John Larson <[EMAIL PROTECTED]> wrote:
Matt - You're absolutely right that you can filter on functions, and if you can see the data you should be there. But, there are two things I don't understand. First, I've only ever seen the sql error message when you are trying to put together a fetch specification for an attribute that isn't in the model, but is in code. But, it doesn't look like you're fetching from the db here. That's just a disclaimer that I'm not sure what's happening there. Second, is the method hasOpeningPlusZeroDays in the State class? If it is, then when you filter on the array of galleries "galleriesActive()" EOQualifier isn't going to find the field hasOpeningPlusZeroDays because it isn't in the gallery's keypath. (assuming that the galleries is full of galleries and not states) Lastly, I'm a little confused what you're doing there at the end altogether, because it looks like you have a circular reference: galleriesWithOpeningPlusZeroDays uses hasOpeningPlusZeroDays and hasOpeningPlusZeroDays is using galleriesWithOpeningPlusZeroDays.
