Hi. I’m new to rails, and I must say I’m loving it.  
I have a question that some of you may already found the answer.

Here’s the problem  
I’ve made a simple user signup interface that sends a confirmation  
link to the email of the link.  
The problem is that I want to confirm if everything is ok before  
saving including the sending of the confirmation email.

So:

So i have

@user.get\_confirmation # To populate the confirmation fields.  
if @user.save  
@user.send\_confirmation  
else  
…  
end

The problem is that @user is saved before the confirmation is sent so  
my only option is to display a message that there was a problem with  
the confirmation email, and delete the record after.

Is there a method like @user.save\_test  
so that I can make something like this:

@user.get\_confirmation  
if @user\_save\_test  
if @user.send\_confirmation  
@user.save  
end  
end

Thanks in advance.

You should use a before\_save callback in your model.  
Something like this:

Class User  
def before\_save  
self.send\_confirmation if self.valid?  
end  
end

Also, you should take a look at:  
[http://guides.rubyonrails.org/activerecord\_validations\_callbacks.html](http://guides.rubyonrails.org/activerecord_validations_callbacks.html)

Hope it helps.

## Cheers.
