For anyone who is still having problems with the syntax for the inserted crop_command in cropper.rb, what worked for me (rails 2.3.5, ruby 1.8.7) was

"-crop #{target.crop_w.to_i}x#{target.crop_h.to_i}+#{target.crop_x.to_i}+#{target.crop_y.to_i} "

No additional quote marks

For anyone still supporting a rails 2.3x app, the syntax that works for your migration is

def self.up
add_column :users, :tasks_count, :integer, :default => 0

User.reset_column_information
User.find(:all).each do |u|
 User.update_counters u.id, :tasks_count => u.tasks.count
end

end

def self.down
remove_column :users, :tasks_count
end

note the handling of tasks_count in the do loop...
