Sunspot/Solr raketasks未在Rails 3可安装引擎中加载 [英] Sunspot/Solr raketasks not loading in Rails 3 Mountable Engine

问题描述

我正在尝试将 sunspot_rails 宝石添加到我的

I'm trying to add the sunspot_rails gem to my Rails Mountable Engine, so I can use Solr to do full text searches. Like it states in the README file I've added this to my Gemfile:

gem "sunspot_rails"
gem "sunspot_solr"

然后运行rails g sunspot_rails:install，它会在Rails Engine的config文件夹中创建sunspot.yml.要启动黑子，我需要运行:

Then I run rails g sunspot_rails:install which creates sunspot.yml in the config folder of my Rails Engine. To start sunspot I need to run:

bundle exec rake sunspot:solr:start

但这不起作用，并给我以下错误消息:

But that doesn't work, and gives me the following error message:

rake aborted!
Don't know how to build task 'sunspot:solr:start'

似乎它没有加载Sunspot/Solr rake任务，因此找不到它们.我还遇到了其他问题，Rails引擎无法加载将在正常Rails 3应用程序中自动加载的文件.我怀疑沿着这条线的事情也在发生.我检查了lib/tasks文件夹，并且那里只有一个文件:my_app.rake.在该文件中，只有几行注释行代码:

It seems that it doesn't load the Sunspot/Solr rake tasks, and so it can't find them. I've had other issues with the Rails engine not loading files that would load automatically in a normal Rails 3 application. I suspect something along that line is going on here as well. I checked the lib/tasks folder, and there is only one file in there: my_app.rake. In that file there are only a few commented lines of code:

# desc "Explaining what the task does"
# task :my_app do
#   # Task goes here
# end

我认为我可能需要手动添加raketasks，然后从my_app.rake加载它们.但是，我找不到有关如何执行此操作的任何信息，也许我一开始就完全错了.希望有人在stackoverflow上有经验.

I think I would maybe need to add the raketasks manually, and load them from my_app.rake. However, I can't find any information on how to do this, and I maybe I'm completely wrong in the first place. Hopefully someone on stackoverflow has experience with this.

无论如何，非常感谢您提前提供的帮助！

In any case, thank you very much for any help in advance!

推荐答案

几天前我自己找到了解决此问题的方法，因此为了完整起见，并(希望)对他人有所帮助，我将发布解决方案在这里.

A few days ago found a solution to this problem myself, so for the sake of completeness and (hopefully) to be of help to others, I will post my solution here.

实际上发生此问题是因为Rails 3可安装引擎的行为与正常的Rails应用类似，但也有许多次要/主要差异.您只需要运行bundle exec rake app:sunspot:solr:start而不是bundle exec rake sunspot:solr:start.

The problem actually occurs because a Rails 3 Mountable Engine behaves a lot LIKE a normal Rails app, but also has a lot of minor/major differences. You just have to run bundle exec rake app:sunspot:solr:start instead of just bundle exec rake sunspot:solr:start.

因此，要使Sunspot在Rails 3可安装引擎中工作，请按照以下步骤操作:

So to get Sunspot working in a Rails 3 Mountable Engine, I followed these steps:

添加到Gemfile

# Gemfile (Don't forget to move them to your gemspec when packaging your engine)

gem 'sunspot_solr' #only for development mode
gen 'sunspot_rails'

之后，请不要忘记运行bundle install来安装gem.

After that, don't forget to run bundle install to install the gems.

配置引擎以使用Sunspot/Solr

要生成所需的config/sunspot.yml文件，请运行:

To generate the needed config/sunspot.yml file run:

rails generate sunspot_rails:install

在本地计算机上启动Solr

最后，要启动Solr的本地实例，请运行:

Finally, to start a local instance of Solr run:

bundle exec rake app:sunspot:solr:start

现在您已经准备就绪！
