Rails: Update model attribute without invoking callbacks

Question

I have a User model that has a :credits attribute. I want a simple button that will add 5 to the user\'s credits, through a route called \"add\" so that /users/3/add would ad

Answer 1

As a general answer, in Rails 4 this is a simple way to update attributes without triggering callbacks:

@user.update_column :credits, 5

If you need to update multiple attributes without triggering callbacks:

@user.update_columns credits: 5, bankrupt: false  

There are other options here in the Rails Guides if you prefer, but I found this way to be the easiest.
