Hi

I have to store id information from items table and send it to the  
notes edit.

So I have link

\<%= link\_to “note”, :controller =\> “notes” , :action =\> “new”, :id  
=\>@item %\>  
this should send only id from item table here is the action from items  
controller

def edit  
@categories = Category.find(:all)  
@item = Item.find(params[:id])  
end

Controller from notes is

def new  
session[:item\_id] = @params[:id]  
@note = Note.new

```
respond_to do |format|
  format.html # new.html.erb
  format.xml { render :xml => @note }
end

```

end

I haven’t found solution for the error :

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.[]

Should i change session[:item\_id] = @params[:id] TO session[:item\_id]  
= @item

Not entirely sure what you;re doing, but @params doesn’t exist any  
more. It’s just params.
