I have a project that is having some issues in clearing cache files in  
any environment that allows for data caching.

This is the error that I am getting:  
ArgumentError in Admin/pagesController#destroy

wrong number of arguments (1 for 0)  
RAILS\_ROOT: /Users/chris/Documents/Projects/Rails/app

# ================= Here is my controller code:

class Admin::PagesController \< ApplicationController  
before\_filter :login\_required\_for\_staff\_member, :find\_account  
layout “admin”

def destroy  
@page = @account.pages.find(params[:id])  
if @page.destroy  
flash[:success] = “The page was deleted”  
redirect\_to admin\_pages\_url  
else  
render :action =\> “index”  
end  
end

Any ideas?

Thanks for the help.

after\_destroy.

Unfortunately, there is nothing that is being called in the after  
destroy and I don’t see anything in the acts\_as\_paranoid that would  
cause the problem.

class Page \< ActiveRecord::Base  
belongs\_to :account  
has\_many :contents  
has\_many :current\_contents, :class\_name =\> “Content”, :conditions =\>  
‘expires = false or expires\_on \> “#{Date.today}”’, :order =\> “id desc”  
has\_many :expired\_contents, :class\_name =\> “Content”,:conditions =\>  
‘expires = true and expires\_on \< “#{Date.today}”’, :order =\> “id desc”

validates\_presence\_of :name

acts\_as\_paranoid

def to\_param  
“#{id}-#{name.gsub(”\s", “\_”)}"  
end

end

🙂 There was a different sweeper that was calling the after\_destroy  
method. I missed that one.

Thanks for the help Ryan.
