I did solve the problem. First I tried:
def index
hobo_index Assignment.find(:all, :order => "due_date ASC" , :conditions =>
["show_date <= ?", Time.now])
end
which made some progress, since the select was executed on the database. But
now I got an error:
undefined method `scope' for #<Array:0x1055e62e8>
the top of the trace is:
/Library/Ruby/Gems/1.8/gems/hobo-1.0.1/lib/hobo/model_controller.rb:454:in
`send'
/Library/Ruby/Gems/1.8/gems/hobo-1.0.1/lib/hobo/model_controller.rb:454:in
`find_or_paginate'
/Library/Ruby/Gems/1.8/gems/hobo-1.0.1/lib/hobo/model_controller.rb:483:in
`hobo_index'
I looked in model_controller.rb and saw the line:
finder = args.first || model
and tried
def index
hobo_index(model,:conditions=>["show_date <= ?", Time.now], :order =>
"due_date ASC")
end
And this worked. Just wanted to document this example in case anyone follows
these threads. I know I do!
Thanks,
Mark
