It is no good just saying it is not working, what response do you
expect from that?

the difference might be illustrated by the following:
Article.where(:hidden => true).to_sql
vs.
Article.where(:hidden => true).all.to_sql
in the first, you are able to get the (currently un-executed) sql
statement
in the second, you will get an undefined_method error because having
been evalua

Look in your development log and ensure that you don't touch the scope

I am getting this not only in console but application also. Has
anything changed in Rails3.0.5?

At the end of the day, the most important thing is that it works. However, I
think we should try to get the database do the work. I'll apologize in advance
that this example is rails2.
# Project -> TaskList -> Task
Project.all(:group => "projects.id", :joins => {:task_lists => :task},

Here you have a right solution, but this code should be written in

Just To clarify the last statement, the Database environment was 4D

that". I'll also admit I have no idea how efficient this is.
I've used a technique where I query a belongs_to table with the ids of
a has_many related table. In my test I have
Assessments has_many -> Questions has_many ->
