问题 I have a basic nested form. I want to access a virtual attribute for the nested form's model. Model 1: Lease Has_many :transactions accepts_nested_attributes_for :transactions, :reject_if => lambda { |a| a[:dated].blank? }, :allow_destroy => true ...

问题 I am trying to implement a rails tagging model as outlined in Ryan Bate's railscast #167. http://railscasts.com/episodes/167-more-on-virtual-attributes This is a great system to use. However, I cannot get the form to submit the tag_names to the controller. The definition for tag_names is : def tag_names @tag_names || tags.map(&:name).join(' ') end Unfortunately, @tag_names never gets assigned on form submission in my case. I cannot figure out why. SO it always defaults to tags.map(&:name)

Single virtual attribute definition for multiple fields

问题 I'm wondering if there is a way to set a virtual attribute so that it can handle multiple fields/variables. Basically, I have several different integer columns in my model (income, taxes) and for each of them I need to check when the form is submitted, and remove illegal characters, which I'm doing by setting a virtual attribute and using tr to strip the characters. def flexible_income income end def flexible_income=(income) self.income = income.tr('$ ,', '') unless income.blank? end And then

问题 Context: I have a company model with many projects , having many tasks . The company also has many employees , which in turn have many tasks .

Can it be somehow populated along with DB attributes? Or am I doing something wrong that is not populated however it should be? Thanks! 回答1: Docs: Massive Assignments Like normal models, Active Record instances also enjoy the massive assignment feature. Using this feature,

问题 I just spent quite some time trying to resolve a virtual attribute issue in my model. It turned out I'd simply forgotten to add it to attr_accesible in my model. Granted I should have caught it earlier or better should have started the whole endeavor by adding it to attr_accessible in the first place. To keep this from happening again, is there a configuration setting I can flag to throw an exception on development if I try to mass assign something and validate it when it is protected
