If you are using django in the "normal" way - you should just be able to add the message to the messages contrib package. Then the message should show when saving? Because when you click on the save button you should post your form and that method should (when successful) add the message? > > It was that behaviour which made me start this thread. > > I checked out typescript and it looks great but it is javascript.

And my other point is still valid. Look at the user base. When you have problems with transcrypt, how many users can you rely on to get help? If you have a pure javascript problem - how many users can you rely on for help?
