gontran - Thanks.
However, I tried the sample code in your link, and I don't think it will work. Returning a string from the overridden save() method prevents the record from being saved to the database, but by the time the save() method is invoked, my ModelForm (and consequently, I presume, the underlying Model) has already been tested as valid. The Restaurant isn't saved, but the form isn't redisplayed and no error message is shown, and code execution proceeds as if the form were valid (because it *is* valid; it just wasn't saved). I think I need to override the model validation instead. Perhaps I need to override Model.clean_fields()? -- You received this message because you are subscribed to the Google Groups "Django users" group.
