Count results of a query?

Ruby
1

Hi,

I have this code

@users = find(:all, :conditions => conditions, :page => {:size =>
page_size, :current => page_num} )
if (@users.count == 0)
flash[:notice] = “No results found.”
render :action => ‘search’
end

but as many of you can guess, it gives me a “undefined method: count”
error. Same if I try “length”. What is the right way to count the
results of the query? - Dave

@users.size

In the future, simply open up irb and type the following
@users.methods - Object.instance_methods
