Strange wildcard problem
Hi,
Apologies for reposting this for those who read this via ruby-forum,
but it didn''t make it to the list before, and the list seems more
active...
I''m using ferret (via acts_as_ferret) in a somewhat unorthodox
manner and am having a strange wildcard problem. Before anyone wonders
why we''re doing things this way, the answer is basically that it lets

Update second pulldown menu based on first menu selection?
I know I''ve seen this somewhere on this board and just can''t search it
anymore.
I have three relational tables: clients, projects, and tasks. Currently
I''m working on customizing the ''new/edit'' task _form. So far I have it
listing clients in a pulldown menu so I can assign the new task to a
client. I''d like to have a second pulldown select

Hi..Guys new plugin again
Hi..
Guys new plugin again
Foreign Key Associations is a plugin that automatically creates
associations based on foreign-keys. The associations are created at
runtime-ie. as your ActiveRecord models are loaded-so they will always
be up-to-date.
For example, given a foreign-key from a customer_id column in an
orders table to an id column in a customers table, the plugin
creates:

Sorting by multiple categories
I have a database with a field called ''category''.
''category'' contains the categories separated by a "," i.e. 1, 2, 5
I know with something like:
@products = Product.find(:all, :condition => "category = ''1''")

Difficulty using correct moldel for the data in DB
Hi everyone,
I''ve tried posting the same question to the list last Friday but
somehow did not see it being posted..
I''ve just started with Rails and Ruby. I just started to play one of
those RPG and to get my feet wet I''m writing an app to keep track of
item fusions. So the scoop is that item can be fused with another
items to create a higher level item. The higher

RESTful routes and resulting urls
if I have the following in my routes.rb:
map.resources :product_categories
it provides urls such as:
/product_categories
/product_categories/1
/product_categories/1;edit
etc.
and uses the ProductCategories controller.
how can I keep the same controller (and model) but set up the resources
so that I can have any abitrary url point to the existing controller,
much like specifying the controller

creating a pulldown entry on the fly
My first ROR app is coming along nicely. This is definately a agile env.
One of my last issues before inhouse deployment is creating pulldown
entries on the fly.
In particular, I''m writing a job tracking app for my company. We
mostly do jobs for the same customers (law firms), so I have a pull
down of law firms which is populated from a law_firms table. i.e

Agile Depot Tutorial Help
anyone can explain me why in the Agile Depot Tutorial application they
use i.product_id
to find if a product already exist in the cart, because the cart
contains items, each of them references a product.
I tried i.product_id like in the tutorial
and
i.product.i
all of these 2 notation works , but i find the second seems more
clean??? isn''t it.
Any explanation will be fine

Saving one-many associations (elegant solution please)
What is the most elegant way to save new one-many associations?
order = Order.new(:name => "My Order")
order.line_items << LineItem.new(:product_id => 1, :quantity => 2)
order.line_items << LineItem.new(:product_id => 2, :quantity => 5)
order.save
The above - which is by far the most elegant way of putting it - doesn''t
work for me - the line_items
