method

update_attributes

v3.2.13 - Show latest stable - Class: ActiveRecord::Persistence

update_attributes(attributes, options = {})

public

Updates the attributes of the model from the passed-in hash and saves the record, all wrapped in a transaction. If the object is invalid, the saving will fail and false will be returned.

When updating model attributes, mass-assignment security protection is respected. If no :as option is supplied then the :default role will be used. If you want to bypass the protection given by attr_protected and attr_accessible then you can do so using the :without_protection option.

      # The following transaction covers any possible database side-effects of the
      # attributes assignment. For example, setting the IDs of a child collection.

        self.assign_attributes(attributes, options)
        save
