changing find method
Hi,
i was wondering if there was a nice clean way(after all, it is ruby) to
change the find method of a certain model/class (Page) so that if i
wanted to use a find method on a @page instance it would return only
specific rows from the table(if the page.published == true/false:
the pages table looked like
SQL:
...
id int not null auto_increment,
published tinyint(1) not null,

Boolean circles..
Hi,
This is just kindof a RoR question, but since you all potentially do
the same things as I do, I thought I''ll ask here..
Im trying to use the boolean type in the database. Migrations is no
problem, it even converts the 0/1 values from my import CSV to false
and true.
However, I cannot make the :conditions part of a find work:

''Series'' Pluralization
Howdy,
I have a model I called ''content_series''. I created it and noticed that
Rails called it ''Sery'', so I added ''series'' to the uncountable thing in
the config, like this:
Inflector.inflections do |inflect|
# inflect.plural /^(ox)$/i, ''\1en''
# inflect.singular /^(ox)en/i, ''\1''

Bug? find_by_id(nil) returns object just created
Tried to submit a ticket in Trac, but it reported an error...
Doing a Model.find_by_id(nil) after creating an object of type Model returns
that object -- and the next time, returns nil. It should always return nil.
For example,
Step 1. Create an object:
>> Foo.create(:name => "bar")
=> #<Foo:0x2aaaac3ade20 @new_record=false,

find_by_id(nil) does not always return nil
I have a model named User. When running this application from the
console I can call User.find_by_id(nil) and it returns nil. When running
this application during testing or through WEBrick or Mongrel calling
User.find_by_id(nil) returns the newest record in the database. But it
only does this the first time you call it with nil. The second time you
call User.find_by_id(nil) it returns nil.

Okay, what gives? find_by_id is failing.
This has the look of a "just don''t quite get it yet" problem. I am
using the ActiveRecord.find_by_id method to identify the parent object
(Quiz) to tie to the child object (Question) at create time.
Here is the stdout log:

find_by_id vs. find in postback action
I''m playing around with the Postback action recipe listed in the recipes
book.
Here is the default code given:

if request.post?
@recipe.attributes = params[:recipe]
redirect_to :main_url and return if @recipe.save
end
end

Automatic finder
It looks rails automatically creates a "finder" method on models that have a "belongs_to". So I tried this in the console:
c = Category.find(2)
chunks = Chunk.find_by_category(c)
chunks is always returned as an empty array. When I know have some chunks with a category_id of 2.
Should the find_by_category do what I think it should be doing or am I completely off base?
