I have a user model with “validate\_uniquness\_of :username”.

How to use build-in validations and in\_place\_editor?

I run Rails 2.1.

I needed to do the same thing only with phone numbers and email address,  
so what I did is used a before\_save callback in my model to check on  
them to make sure they were formatted properly. I do, however, have the  
exact same code that you have - validate\_uniquness\_of :username. Is this  
not working for you or is it throwing some kind of error?

when I work in the console and try to create a user with an already  
existing  
username the error message is shown. but when I use in\_place\_editor I  
can  
change a username to let’s say “jochen” although there’s already such  
an entry  
in the db.

The problem is how to tell the in place editor that validation  
failed. Take a look at  
[http://www.schumeyer.com/index.php/in-place-editor](http://www.schumeyer.com/index.php/in-place-editor)

I believe this will do what you want.

I have not had time to write much explanation. Feel free to email me  
with any questions.
