In order to update a field there are many methods in Rails. But, to update a field in Database directly you should be using update_column or update_columns.
update_column
update_column( :field_name, field_value )- It doesn't validate the record.
- It doesn't call callbacks.
- It doesn't call save method.
Thus, updates the record in Database directly by not going through regular update procedures.
update_columns
update_columns( field_name: field_value )- It doesn't validate the record.
- It doesn't call callbacks.
- It doesn't call save method.
- It works for version above 3 in Rails.
Keep Coding !!!
