I have a form with 3 fields: user\_id, email and password.  
All 3 fields are required, so I have a “validates\_presence\_of :user\_id,  
:email, :password” in my model.  
Works, but the validation errors show up in a different order than I  
specificed in the validates\_presence\_of statement.

Is there a way to specify the order in which the validations (and  
corresponding error messages) should occur using the built in validation  
methods like validates\_presence\_of?

Thanks for the assistance,  
Jeff

Have you tried:

validates\_presence\_of :user\_id

validates\_presence\_of :email

validates\_presence\_of :password

Yes, same results: email can’t be blank, followed by user id then  
password

I think the validation targets are stored in a hash, in which order is  
never guaranteed.

Seems like someone was annoyed with this a while back and created a  
plugin to control  
order of validation… EZ was that you? Hmm, actually I think it was  
another  
over-achiever… Well, you might search the wiki and/or google for it.
