Functional Testing
Hey all,
I have a many-to-many relationship (Questions
has_and_belongs_to_many Answers), and when I destroy
the Question (the one) I also destroy all the Answers
(the many).
Since the following doesn''t seem to work for
has_and_belongs_to_many:
class Question < AR::Base...
has_and_belongs_to_many :answers, :dependent =>
:destroy
end
I have this embedded in a transaction block

collection_select question
How do I specify which option should be initially selected when using
the collection_select command? I''ve tried:
collection_select(:selectionfilter, :producer_id, Producer.find(:all),
:id, :name, {:include_blank => true, :selected_value =>
@initial_selection})
However it doesn''t return the desired results (the option with the value
of @initial_selection selected).

Advice, why value_before_type_cast in FormHelper?
I am wondering why is in creating text fields with form_helper used
value_before_type_cast instead of attribute value for field value?
I set rails enviroment so date fields are in european format
(dd.mm.yyyy) and would like to have same format in forms, but because of
value_before_type_cast is called, form fields are filled with
''yyyy-mm-dd'' or timestamp integer, etc.

scaffold misuse?
Running ruby script/generate scaffold Product Admin
is a wonderful way to set up well, exactly what it says, a scaffold.
My problem is that I have several other tables that are linked,
through foreign keys, to the Product table. Say an "authors" table.
Now when I go enter a new product, a book, I want the application to
provide a drop down list of authors generated from the records in

quick q on script/generate scaffold
I want a scaffold to manager both products and users. To get the
products scaffold I used
script/generate scaffold Product Admin
if I use,
script/generate scaffold User Admin
will it overwrite my product admin controller? Would I be better off
doing
script/generate scaffold User User_Admin or something?
