Answer 1

Based on debugging together with OP, found that the given method actually does much more than written. In last line of method, #booking = Booking.paginate(:per_page => 100) was being done which dissolved the query set generated earlier.
The final variant looked something like this:
def revenue
#bookings = Booking.all
if params[:currency].present?
#bookings = #bookings.where(currency: params[:currency])
end
if params[:search].present?
#bookings = #bookings.where('first_name like ?', "%#{params[:search]}}")
end
if params['date'] && params['date']['month']
#selected_date = Date.parse('2018-'+ params['date']['month'].to_s + '-01')
#bookings = #bookings.where('extract(month from created_at) = ?', params['date']['month'])
end
if params['date'] && params['date']['year']
#selected_year = params['date'] && params['date']['year'] ? Date.parse( params['date']['year'].to_s + '-01') : Date.today
#bookings = Booking.where('extract(year from created_at) = ?', params['date']['year'])
end
#per_page = params[:per_page] || Booking.per_page || 20
#bookings = #bookings.paginate(:per_page => #per_page, :page => params[:page])
end
