我想在我的 spree 扩展中添加新的 javascript 文件

Question

我是 Rails 新手。我正在尝试构建 Spree 扩展以使用 Braintree 的插入式 UI。我正在尝试将新的 Braintree.js 添加到我的扩展程序中。这些是我到目前为止所做的步骤。

1. 已将braintree.js 添加到<my_extension>/app/assets/javascripts/spree/frontend/

2. 已将//= require spree/frontend/braintree 添加到app/assets/javascripts/spree/frontend/<my_extension>.js。

3. 在<my_extension>/config/initializers/ 中创建braintree.rb。该文件的内容：

   Braintree::Configuration.environment = :sandbox
   Braintree::Configuration.merchant_id = "merchant_id"
   Braintree::Configuration.public_key = "public_key"
   Braintree::Configuration.private_key = "private_key"
   

4. 我从我的狂欢商店跑了bundle install，这很成功。

5. Ran rails g <my_extension>:install 这给了我以下错误：

   append  vendor/assets/javascripts/spree/frontend/all.js
   append  vendor/assets/javascripts/spree/backend/all.js
   insert  vendor/assets/stylesheets/spree/frontend/all.css
   insert  vendor/assets/stylesheets/spree/backend/all.css
   run  bundle exec rake railties:install:migrations FROM=spree_hello_ext 
   
   from "."
   Would you like to run the migrations now? [Y/n] y
   run  bundle exec rake db:migrate from "."
   rake aborted!
   NameError: uninitialized constant Braintree
   /Users/<user>/Sites/spree_hello_ext/config/initializers/braintree.rb:1:in 
      `<top (required)>'
   /Users/<user>/Sites/hellostore/config/environment.rb:5:in `<top (required)>'
   Tasks: TOP => db:migrate => environment

你需要在你的 gemspec 中要求 Braintree gem 作为一个依赖项，然后要求它 lib/spree_hello_ext.rb 以便在你的初始化程序尝试使用它之前对其进行初始化。类似于 spree_gateway 所需的 spree_core： https://github.com/spree/spree_gateway/blob/master/lib/spree_gateway.rb#L1
