Hi, I’m writting a rails app to manage mp3 files online. I want to updade distinct model objects in different situations. 1. When an user go to save a new record, I code the controller to save all fields to DB, without restrictions. (this was done). 2. When an user go to save an existing record, two cases can happen: a) the record is of the proper user: so, I want to code the controller to show informations to that user, like “the \ has been saved by you. Do you want to edit them?” and display the related form. But, I have another solution: only display the informations and highlight the mp3 entry. What the best solution, for this case? And, if possible, how can I code this? b) the record is of another user: so, I want to code the controller to show a form with unique input fields readonly, like “title” and permit other fields to be salved by the user. But, this time, the field ‘description’ will be saved as a comment for the existing entry, in a table comments for the model Comment. How can I code this? When I have a Comment model and need know ‘who’ comments ‘what’ file, but the Comment belogs\_to ‘MP3 model’, can I put a user\_id field in the comments table? Or would more currect put it in another place? If so, where? Thanks for the support, Ranieri T.
