# I have the following model

class SoftwareCi \< ActiveRecord::Base  
has\_one :ci, :as =\> :content  
has\_one :primary\_group  
validates\_presence\_of :name, :message =\> “can’t be empty”  
end

# The controller

def create  
@software\_ci= SoftwareCi.new(params[:ci])  
redirect\_to :action =\> ‘create\_ui’

end

# The rhtml, create\_ui, I have given the following

\<% unless @software\_ci.errors.empty? %\>  
Error occurred!

 \<% @software\_ci.errors.each\_full do |message| %\> - \<%= message %\>
 \<% end %\> 
\<% end %\>
# The problem

I get the following error in the view

You have a nil object when you didn’t expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.errors

Could you please help me?
