# If you find yourself ignoring temporary files generated by your text editor

Changing the counts is business logic that should go in the model. One way to think about whether it's business logic or not is to consider if you are manipulating the data. If you are, stick it in the model!

video.save
customer.videos_checked_out_count += 1
customer.save

render json: { customer_id: rental.customer_id,
video_id: rental.video_id,
due_date: rental.due_date,
videos_checked_out_count: customer.videos_checked_out_count,
available_inventory: video.available_inventory }
else
render json: {
errors: ['Not Found']
}, status: :not_found

return

Similar to above, this business logic should go in the model.

rental.customer.save
rental.video.available_inventory += 1
rental.video.save
rental.returned = true
rental.save

render json: { customer_id: rental.customer_id,
video_id: rental.video_id,
