{ :name => “Project A”, :description => “” }

Perhaps you really want the “description” field to be NULL in the database and not “” as it will be by default.

two other notes….

first, brightbox provides ubuntu (and probably debian-compatable) packages for hardy, which make the installation process more–straightforward.

secondly, passenger requires log files to be worldwriteable, which doesn’t strike me as the most brilliant thing in the world, but its no great risk and it is what it is.

Anyways I can recommend a different approach to heirarchies called the nested set model (http://dev.mysql.com/tech-resources/articles/hierarchical-data.html). With rails there are several plugins implementing this, just search on GitHub for “nested_set”.

With you example i have two levels

I need four or five levels – recursive categories

(I need this bad sample)
:conditions => [“categories.id = ? OR categories.parent_id OR categories.grandparent_id = ? OR .. (etc..)

How can count total Products in each parent level?

CategoriesHelper code:

def find_all_listsubcategories(category)
if category.children.size > 0
ret = ”
category.children.each { |subcat|
ret += ”
ret += link_to h(subcat.name), :action => ’show’, :id => subcat
ret += ”
}
ret += ”
end
end

Can you help me please, I’m not a developer. I’m Web designer

Sorry, i don’t speak english very well

thank you again!

1. I am NOT using a domain name for the internal test server — hence the ip address instead.

2. Just to clarify: I was able to install passenger from the ubuntu deb repo, as well as uninstall it and then try the gem install method. The installations apparently worked (or didn’t kick up any errors at the time), but I still can’t get my app served.

Someone may recognize my test app “shovell” was built from the tutorial in Simply Rails 2 — an excellent intro to Rails by the way, though weak in the deployment stuff, and a couple of years out of date.

Thanks

I’m trying to set up a rails test server on my lan, and not having much luck using passenger.

The server is an ubuntu 8.04 server edition VM (VirtualBox, bridged nic), running Apache, MySQL and Rails.

I can hit the server from my lan (the host pc, actually), using 192.168.2.xxx, and I can hit my test rails app after launching Mongrel server in production mode from 192.168.2.xxx:3000.

I tried installing passenger from the ubuntu deb repository, and when that didn’t work, through gem (where it apparently builds passenger for the onboard Apache version).

In either case the result is the same: it doesn’t work.

Since I’m using a domain name for the server, I configured the “default” VirtualHost site as follows:

————code snippet————
NameVirtualHost *

ServerAdmin webmaster@localhost
DocumentRoot /home/dave/shovell/public

Options FollowSymLinks
AllowOverride None

————————————
(note only DocumentRoot and Directory are changed from the original file).

I have also tried setting up a symlink to the above directory in /var/www and adding a RailsBaseURI line. Without the line, my browser opens the directory (rather than the rails app). With it, I get the same, 500 Internal Server Error message

Although my Rails installation and test app seem to be fine, judging by being able to run it in Mongrel, the Apache error log is reporting a slew of Ruby errors:

Any help in identifying where the problem lies, and how I might go about fixing it would sure be appreciated! I already took a stab at the mongrel + mod_proxy method and got nowhere.

Thanks.
