问题 I try install pundit. But when I set up the gem I have this message. error message I don't really understand. I am user.admin maybe is there a conflict? Thank you for your answer. 回答1: Pundit adds a method to your controller called verify_authorized that ensures that the authorize method is called somewhere in your controller action.

问题 I have a Rails 3.2.18 app where I'm trying to do some conditional validation on a model. In the call model there are two fields :location_id (which is an association to a list of pre-defined locations) and :location_other (which is a text field where someone could type in a string or in this case an address). What I want to be able to do is use validations when creating a call to where either the :location_id or :location_other is validated to be present. I've read through the Rails

问题 I am trying to get Capistrano up and running for the first time in a rails app. I have a linux server running Ubuntu 12.04, nginx, unicorn and rails, however, I seem to be running into a few issues.

To get the first element, pass a block that indexes the array.
