Noob DRY method question
Hi Gurus, I''m learning the Rails framework, and I have this exact
block of html/javascript in two places in an if/else construct in
application.html.erb:
<body onload="Modalbox.show(''<div class=\''warning\''> <p> <center> <%=
flash[ :notice ] %> </center> </p> <p> <center> <input

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

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

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

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

Rails model design visualization
I''m a fairly visual person, and I have a piece of paper with many
boxes and arrows with labels like "has many" and "belongs to" for my
database models. It''s messy, but it works.
What I keep looking for--weeks, actually, I''m certain it''s out there,
but I haven''t hit on the right set of Google query terms :)--is
something that will

Frozen hash problem
I''d like to delete some records before saving them. I ran this
experiment:
before_save :prune_lab_datas
def prune_lab_datas
lab_datas.each do |lab_data|
lab_data.destroy
end
raise lab_datas.to_yaml
end
But nothing seems to be deleted in the hash:
---
- &id001 !ruby/object:LabData
attributes:
created_at: 2010-03-21 22:16:06
unit_id: "3"
