Help w/ errors.add\_to\_base between controller and model

Hello,

```
I'm having trouble in routing some errors between model and

```

controller. The errors produced in the controller  
(invite\_controller.rb) are collected and spit out nicely in a  
flash[:validate] method as such:

if errors.size \> 0  
flash[:validation] = errors.join(’  
’)  
end

Errors produced in the model (invite.rb) are displayed w/in a giant page  
failure explosion and are not routed into the flash[:validate] method.

The code for the the method is as follows:

self.errors.add\_to\_base(“an invitation has already been sent to  
#{email}”)

Is there a way where I can route the model errors to the  
flash[:validate] method as I am in the controller?

Thanks for your help!

Will something like this work:

if model.save  
flash[:success] = “model successfully saved”  
else  
flash[:validate] = model.errors.full\_messages.join(“\n”)  
end

Hello,

I tried using the flash[:validate] method in the model and it shows  
the “method not found” error.

What exactly does the model.save method do?

More on that- here’s the full errors that are displayed.

Official validation error from the model:  
Validation failed: an invitation has already been sent to  
removed\_email\_address@domain.invalid

And the other errors from the page failure:

/opt/local/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active\_record/validations.rb:748:in  
`save!' #{RAILS_ROOT}/app/controllers/invite_controller.rb:40:in `bulk’  
#{RAILS\_ROOT}/app/controllers/invite\_controller.rb:30:in `bulk’

Can you copy and paste your model and controller action? If it’s big  
use Pastie [http://pastie.caboo.se/](http://pastie.caboo.se/) and post a link here.
