我想将新的javascript文件添加到我的spree扩展名中 [英] I would like to add new javascript file to my spree extension

问题描述

我是新手.我正在尝试构建Spree扩展以使用Braintree的嵌入式UI.我正在尝试将新的braintree.js添加到扩展名中.这些是我到目前为止所做的步骤.

I am new in rails. I'm trying to build Spree extension to use Braintree's drop-in UI. I'm trying to add new braintree.js to my extension. These are the steps I did so far.

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

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

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

Created braintree.rb in <my_extension>/config/initializers/. Content of this file:

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

在狂欢商店中，我成功运行了bundle install.

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

Ran rails g <my_extension>:install which gives me the following error:

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!

推荐答案

您需要在gemspec中要求braintree gem作为依赖项，然后要求它lib/spree_hello_ext.rb才能对其进行初始化，然后再进行初始化.用它.类似于spree_gateway对spree_core的要求: https://github.com/spree/spree_gateway/blob/master/lib/spree_gateway.rb#L1

You need to require the braintree gem in your gemspec as a dependency, and then require it lib/spree_hello_ext.rb for it to be initialized before your initializer tries to use it. Similar to how spree_core it required by spree_gateway: https://github.com/spree/spree_gateway/blob/master/lib/spree_gateway.rb#L1
