问题 I want to test uploading a file in a Rails Rspec request test. I'm using Paperclip for asset storage.

问题 I just upgraded from 5.1 to 5.2 and I'm quite confused about this 'better' methodology to storing secrets... Maybe I'm not understanding, but it seems like now development and production have been 'merged' into a SINGLE SECRET_KEY_BASE as well as master.key ... is this correct?

问题 A migration I created in a Rails 5 application had 5.0 passed into a method: class CreateVariableKeys < ActiveRecord::Migration[5.0] ... end I would like to know what the [5.0] means. 回答1: It is a class method of ActiveRecord::Migration and is defined here.

问题 I'm trying to create a login using devise with a username that I've computed.

问题 I'm using Acts_as_follower in a wishlist app I'm working on. I think it should be working, but the button to actually follow another user is not.
