I'm building an engine and as part of that I want to use acts_as_list.
So I've added 's.add_dependency acts_as_list' to my gemspec file. When
I bundle acts_as_list gets installed as I would expect, and is listed by
'gem list'
However, when I go to use acts_as_list in my model I get method not
I think I've found a workaround.
category.articles.limit(3).count
= 8
category.articles.find(:all, :limit = 3).count
= 3
If I use the old Rails 2 methods, the system works correctly.

I have a relationship where Category has_and_belongs_to_many Article. I
want to grab a small subsection of articles related to a particular

records and gets the wrong number.
The issue is that there is bug in

I've worked out a solution. It might not be the neatest, but it works
for me:
has_many has its own call backs. So I can trigger a logging activity

I am then able to grab the Observe object using

Hi,
I'm using an ActiveRecord::Observer to log users changing data in my
application. However, I've noted that adding an item to a has_many
relationship gets logged, but removing the item does not. That is:
@product.users user
is logged, but:
@product.users.delete(user)
is not.

I think this SQL would do it:
SELECT *
FROM `states`
WHERE created_at '2010-04-16'
OR created_at = (
SELECT created_at

ORDER BY created_at ASC
LIMIT 1)
ORDER BY created_at DESC
LIMIT 1
But your original solution would be easier to maintain!

You can do it with map.connect. You may have to play with the syntax,
but I think this will work:
map.connect 'people/:person_id/:controller',

How do you define which version of the database is populated via the new

Standard rails behaviour is not to redirect if the update fails.
If you redirect on failure, the submitted modifications in the form gets

rake -T lists the available commands. It doesn't give you any syntax for
each command. Specifically, it doesn't list the available parameters and
switches. For example, it doesn't specify that you can use the keyword
'environment' with db:migrate.
