rails update column without callbacks

To update a column in Ruby on Rails without triggering callbacks, you can use the update_column method. Here are the steps to follow:

1. Find the record you want to update using the appropriate model method. For example, if you have a User model and want to update a specific user's column, you can use the find method:

ruby user = User.find(id)

In the above code, id represents the unique identifier of the user you want to update.

1. Use the update_column method to update the desired column without callbacks. Pass the column name as the first argument and the new value as the second argument:

ruby user.update_column(:column_name, new_value)

Replace column_name with the actual name of the column you want to update, and new_value with the new value you want to assign to that column.

Note that this method bypasses validations and triggers no callbacks, so use it with caution.

1. Save the changes to the database:

ruby user.save(validate: false)

The save method with the validate: false option will save the changes to the database without triggering validations.

By following these steps, you can update a specific column in Ruby on Rails without invoking any callbacks or validations.
