新 Rails 3.1.3 + Datamapper 路由资产问题

发布于 2024-12-25 01:33:31 字数 482 浏览 3 评论 0原文

我渴望在新的 Rails 项目中尝试 DataMapper。我使用以下命令创建了我的项目：

rails new project_name -m http://datamapper.org/templates/rails.rb

我决定通过运行来测试我的应用程序：

rails server

当我转到创建的通用主页时，我看不到任何图像。我收到一条错误消息：

ActionController::RoutingError (No route matches [GET] "/assets/rails.png")

如果我创建任何其他脚手架并访问这些页面，我会收到有关未找到样式表或 javascript 的类似错误。我仔细检查以确保常规 Activerecord-rails 应用程序可以正常工作（它确实如此）。我比较疑惑。任何帮助将不胜感激。谢谢：）

I am eager to try out DataMapper for a new Rails project. I created my project using the following command:

rails new project_name -m http://datamapper.org/templates/rails.rb

I decided to test out my application by running:

rails server

When I go to the generic home page that is created, I can't see any images. I get an error stating:

ActionController::RoutingError (No route matches [GET] "/assets/rails.png")

If I create any other scaffolds and visit those pages, I get similar errors about the stylesheets or javascript not found. I double checked to ensure that a regular Activerecord-rails application worked (which it did). I'm rather puzzled. Any help would be greatly appreciated. Thank you :)

由于某种原因，DataMapper 的 Rails 模板完全用自己的模板替换了标准的 Gemfile，其中不包含任何资产处理内容（它还删除了一些其他内容，如 jQuery 支持、TestUnit、ActionMailer） ...）。

设置新应用程序后，您需要将这些重新添加到您的 Gemfile 中：

group :assets do
  gem 'sass-rails',   '~> 3.1.5'
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

根据下面 Frederick 的建议，您还需要将其添加到您的 config/application.rb< /code> 文件：

require 'sprockets/railtie'

我打开了一个问题和提交了拉取请求来解决此问题。

更新：自 2012 年 1 月 5 日起，此问题现已修复。该模板的行为几乎与标准 Rails 3.1 应用程序相同，唯一的变化是 ActiveRecord 被替换为 DataMapper。 Assets/jQuery 支持现在可以使用。

For some reason, DataMapper's Rails template completely replaces the standard Gemfile with their own, which doesn't include any of the asset handling stuff (it also removes a handful of other things like jQuery support, TestUnit, ActionMailer...).

You'll want to add these back in to your Gemfile after setting up the new application:

group :assets do
  gem 'sass-rails',   '~> 3.1.5'
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

Per Frederick's suggestion below, you'll also want to add this into your config/application.rb file:

require 'sprockets/railtie'

I opened an Issue and submitted a pull request to fix this.

Update: As of 1/5/2012, this is now fixed. The template behaves nearly identical to a standard Rails 3.1 app with the only change being ActiveRecord being replaced with DataMapper. Assets/jQuery support now works.
