Select distinict on not chainable with order method
Hi.
I would like to do code refactoring:
@beers = []
Beer.all.each do |beer|
unless @beers.find{|c| c.brand_id == beer.brand_id}
@beers << beer
end
break if @beers.size > 29
end
So I achieved this by writing scope (on PostgreSQL):
scope :with_unique_brand, select("DISTINCT ON (beers.brand_id)
beers.*")
Using this scope alone is working

Interpolation in association conditions broken; broken backwards-compatibility?
I believe it used to be possible to interpolate values into
associations'' conditions with single quotes, but it isn''t anymore.
has_many :widgets, :conditions => ''brand_id = #{brand_id}''
Anyone else remember that? It seems to have been snuffed out in
changeset 3897 with the removal of interpolate_sql(@conditions)

Eventually, i''d like to be able to show a brand name from a

Like Query Across Multiple Tables
Firstly, I''m still learning Ruby and rails, so there could be a very
simple solution to this.
I want to search across multiple tables with a "like" query eg: (SQL is
probably the easiest way to describe it):

products.*
from products
inner join brands on products.brand_id = brands.id
where
products.name like ''%canon%''

collection_select default selected value
Hiall,
Unfortunately I just can''t find out how to setup a default selected
value when using collection_select. My call is like so:
<%= collection_select(:consultant, :lastname, @consultants, :id,
:lastname, { :selected => @current_consultant.id } ) %>
which is not working, I debugged so far that I know that
@current_consultant.id contains the correct value.
Any tips?
cheers

I think options_for_select is backwards
With a hash such as:
stuff = {''1''=>''desc 1'', ''2''=>''desc 2'', ''3''=>''desc 3''}
options_for_select(stuff) will output:
<option id="desc 1">1</option>
<option id="desc 2">2</option>
<option id="desc 3">3</option>
