Possible bug with acts_as_tree and reloading in 0.14.1 ?
(sorry for any duplicates - 24 hours have passed, and haven't seen the
message)
Hi everyone,
I'm not sure exactly what's happening here. I had the following work
perfectly in 0.13.1:
class ProductCategory < ActiveRecord::Base
acts_as_tree :order => 'name'
end
class Admin::ProductCatalog::ProductsController < Admin::SecureController
before_filter :setup_nav, :only => [:public_index, :public_view]
def public_index
@page_title = "Browsing #{@root.name}"
end
protected
def setup_nav
@toplevel = Configuration.get(:public_root_category)
@root = session[:root] || @toplevel
@parents = [@root]
while @parents.first != @toplevel && @parents.first.parent
@parents.unshift @parents.first.parent
end
end
end
@toplevel is an instance of ProductCategory. If I restart WEBrick,
#public_index renders perfectly. If I refresh, I get an undefined
method exception when #parent is called.
I changed setup_nav like this for debugging purposes:
def setup_nav
@toplevel = Configuration.get(:public_root_category)
@root = session[:root] || @toplevel
render :inline => %q(<%= debug(@root)
%><br><br><%@root.has_parent? %><br><%= RAILS_ENV
%>)
return false
end
On the first load, I get this:
<pre class='debug_dump'>--- !ruby/object:ProductCategory
attributes:
name: All Categories
id: "128"
picture_id:
parent_id: </pre><br><br>false<br>development
On the second and subsequent reloads, I instead get the following exception:
NoMethodError in Admin/product_catalog/products#public_index
undefined method `has_parent?' for #<ProductCategory:0x36ef4e0>

[snip -- complete stack trace at end]
There must be something I'm doing wrong, but for the life of me, I
can't see what that is... This application is running under a
Productized version, if that changes anything. I have confirmed that
I'm running in dev mode (as seen above).
NOTE: If I use the new #ancestors method in ActsAsTree, I get the same
kind of behavior - works on first call, fails on subsequent ones.
Thanks for any help in debugging this...
Bye !
François

Re: Possible bug with acts_as_tree and reloading in 0.14.1 ?
Hi, just a guess but are you hanging onto an instance of ProductCategory between requests? If you are then a quick solution is to do: class ProductCategory def self.reloadable? false end end After each request rails clobbers your model classes, removing instance variables and methods. The reloadable? method tells AR not to do that.

Re: Possible bug with acts_as_tree and reloading in 0.14.1 ?

The reloadable? method tells AR not to do that.In fact, I am keeping an instance of ProductCategory in the session. I can now assert that the trick you sent prevents the problem from occuring. I haven't dug up to the end of this problem, but I'd really like to understand what's going on. One thing I haven't tested yet is if running in production would change this behavior ? My gut feeling is yes, since Rails in production won't reload model classes... Thanks for your info, François _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
