Hi,  
I Got will\_paginate as gem and added required things is config/  
environment.rb.

My controller code,  
------\>8--------  
@triedmails = Triedmail.paginate :all, :page =\> params[:page]  
------8\<-------  
My view code,  
------\>8--------  
\<%= will\_paginate @triedmails%\>  
------8\<-------

## It is throwing,

The @automaton variable appears to be empty. Did you forget to pass  
the collection object for will\_paginate?

Extracted source (around line #1):

## 1: \<%= will\_paginate @triedmails%\>

I never pass a variable named @automaton. But I don’t know where it is  
throwing like this. But my controller name is automatoncontroler.

Could any one explain me?

-Sadeesh.

Looking at the code, this is what you’d get if @triedmails was nil
