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
