Drop down list ?
Hi Gurus, I''m trying to tackle a drop down list. I have category and
item dbs, and they''re wired up with category has_many :items and item
belongs_to :category, and an item has a category_id. I have this code
in my new/edit.html.erb for item:
<%= f.collection_select :category_id,
Category.find_main, :id, :header, {}, :multiple => false %>
And a pretty drop down list

More elegant solution for "missing" has-many through ids?
I have LabGroup and LabDesc which have many through LabDescGroup. I''d
like to identify LabDescs which don''t have a LabGroup. This works:
x = []
LabDescGroup.find( :all, :select => ''DISTINCT lab_desc_id'' ).each{ |c|
x << c.lab_desc_id }
y = []
LabDesc.find( :all, :select => ''id'' ).each{ |c| y << c.id }
notfound = x - y

How to generate UML diagrams from existing ruby code?
Hi,
thanks for reading. Till now, I''ve used railroad to visualize my
models. But as far as I can see, there''s no possibility to add
information about the model class methods. Methods are only added to a
diagram, if you visualize your controllers. Is there a way to change
this behavior?
I''ve looked out for something else and found ''ruby-uml'', seems to

uniqueness validation perplexity
I want to write a validate routine to check to enforce that a position
must be unique in a category. (In another category, it doesn''t have
to and shouldn''t need to be unique.) I write this code which works
happily for new items:
def position_in_category_not_unique
@items = Item.find( :all, :conditions => [ "category_id = ? AND
position = ?", category_id,

Calling ActionView from uninheriting class
Hi Gurus, I have a class, specified in models cart.rb, which doesn''t
inherit from anything--it''s just a container
class Cart
...
I just discovered I can''t call number_to_currency in that class. Any
idea how to "include" it in my code? I tried
ActionView.number_to_currency without luck. I could kill a few lines
of non-DRY regexp code in cart.rb if I could

given by WEBrick.
It says many of my database operations are taking 2ms or 7ms... but
the view is taking 40ms. People often say that the database is the
bottleneck in applications (which it most certainly can be, and often
is)... but isn''t the rendering of ERB a little show here? My test

RoR failure
I am a newbie at RoR and am disappointed by the fact that I couldn''t
install it in my Ubuntu 10.10 using an IDE. I tried NetBeans 6.9.1,
Eclipse 3.6.2, Aptana Studio and its plugin for Eclipse and RubyMine.
There was always a problem somewhere (rails, rubygems, rake, etc)
preventing me from working with my project. I currently have Netbeans

Documenting Models
All,
I''m trying to do some documentation on the models for our interfaces
team. I espcially need them to be able to see the relationships
belongs_to and validations. However, I must be stupid with rdoc
because I can''t seem to get those two things in the generated
documentation.
Ideas?
