Does anyone knows if normal ROR validation could be done inside of  
Radiant extensions. I’ve tried regular ROR validation methods like  
validates\_presence\_of inside of my model but it does’t work. Does anyone  
have an idea on how to do that.

Thanks

Validation is a feature of ActiveRecord so it should work flawlessly  
in a Radiant extension. Do you need to restart your mongrels? Do you  
have a parse error in your models?

It didn’t give me any errors in the console and I restarted the server

That’s what the console looks like preparing my submit

What does the code look like in your controller for saving the model?

Can you try this with script/console and see if you get an error:

> > c.save!

When I tried with script/console here is what I got

* * *

Loading development environment.

> > c = Contact.new

> > “driver\_license”=\>nil, “state”=\>nil}, @new\_record=true\>  
> > c.save  
> > =\> false

* * *

and that’s what my action looks like  
\*\*  
def myAction  
radiant\_render :layout=\> “/sub/”  
if session[:contact].nil?  
contact=Contact.new(params[:contact])

```
    session[:contact]=contact

    contact.save
  end

```

end

ActiveRecord::Base#save returns false on validation errors. It’s  
ActiveRecord::Base#save! that throws an error. Try it with the  
exclamation point.

So it seems that it is doing validation, so why I’m not getting the  
regualr ROR Validation box on my page and it is going to the next page  
any ways?  
Any ideas

Thanks

Because the error\_messages\_for(‘contact’) helper call is not in your  
view:

[http://api.rubyonrails.com/classes/ActionView/Helpers/ActiveRecordHelper.html#M001005](http://api.rubyonrails.com/classes/ActionView/Helpers/ActiveRecordHelper.html#M001005)

I tried that but still didn’t work. Here is the question,  
even without error\_messages\_for , it is not supposed to go to the next  
page if I have validates\_presence\_of :first\_name in my model, right?

the weired thing is, it didn’t save anything to the DB but still went to  
the next page. here is how the top part of my view looks now.

\*\*  
\<%= error\_messages\_for ‘contact’ -%\>  
\<% form\_for :contact, :url =\> {:action =\> :auto, :id =\> @contact} do  
|form| %\>

* * *

Thanks

It really depends on how you wrote the action in your controller.  
Something like this might work:

def create  
if request.post?  
contact = Contact.new(params[:contact])  
if contact.save  
flash[:notice] = “Contact saved successfully.”  
redirect\_to show\_url(:id =\> contact)  
else  
flash[:error] = “Validation errors occurred while processing this  
form. Please take a moment to review the form and correct any input  
errors before continuing.”  
end  
end  
end
