Rails update attributes not validating

= 43008) LIMIT 1 User Exists (33.4ms) SELECT 1 FROM `users` WHERE (`users`.`email` = BINARY '[email protected]' AND `users`.`id` != 43008) LIMIT 1 (0.1ms) ROLLBACK One possibility is that you have a User model and an authentication system like Devise or Auth Logic. However, this saves all the attributes on the model in their current state, rather than being able to limit this to certain columns.

Callbacks If perform_validation is false while calling save then it skips validation, and it also means that all the before_* callbacks associated with save.

update_column(name, value) Updates a single column in a database, without calling save.

Also note that Validation Use update_attribute to skip validations.

update_attribute uses save(false) while update_attributes uses save (which means save(true)).

# PUT /expenses/1 # PUT /expenses/1def update @expense = Expense.find(params[:id]) respond_to do |format| if @expense.update_attributes(params[:expense]) else end end end validates_presence_of :employee_id # Declare a required field validates_presence_of :unitcost # Declare a required field validates_presence_of :quantity # Declare a required field validates_presence_of :exp_date # Declare a required field validates_presence_of :category_id # Declare a required field validates_presence_of :description # Declare a required field validates_presence_of :markup # Declare a required field validates :markup, :format = update_attribute Updates a single attribute and saves the record without going through the normal validation procedure.

I especially like to impose such cleaning rules on objects used for crossing boundaries such as Command or Form objects.

I can't spot any errors in my log file, either, though maybe I'm not reading it correctly. Removed the bang, but it's giving me the "I am trying to update" message.
