阅读更多关于 Why does my stripe elements form not work on rails?

问题 I'm trying to get Stripe.js to work on my rails app. I am using stripe elements. I have followed the instructions on the stripe docs. The form card input is not showing up where it should.

阅读更多关于 Rails ActiveStorage scope for when file is attached

问题 When using ActiveStorage, how do you create a scope for when files are attached. For example: class Check < ActiveRecord::Base has_one_attached :image end I want something like Check.has_attached_image to return only records where there is an existing attached image. I know that ActiveStorage provides a with_attached_image scope. But that doesn't seem to be working: irb(main):009:0> Check.with_attached_image.to_sql => "SELECT \"checks\".* FROM \"checks\"" 回答1: Main purpose of the scope with

阅读更多关于 How do you render HTML tags in React with Coffeescript?

The first one pertains to React.createClass
