10,847 PointsWithout seeing your code it's hard to say. One thing that stands out to me is "time_entries" - plural. Just like Customer is singular, time_entry should be also - the model name is singular, the table name is plural. So, try this:
Customer.first.time_entry

4,081 PointsThanks Tommy
I got it , i had made a mistake of refering to the table as 'customers' in the migration file and hence the id created was 'customers_id' when it should have been 'customer_id' . Fixed that and this command is working .
Customer.first.time_entries ( the video shows exactly this )
