标签: ruby-grape

我想使用grape来通过命令行安装库.所以我发出了命令:

grape -V install org.apache.derby derby 10.5.3.0

Grape应使用位于http://127.0.0.1:8081/artifactory/webapp/home.html的Maven存储库.我该如何配置？

启用详细模式后,我在日志中看到:

有人可以解释为什么即使我已经使用Grape安装了依赖项,Groovy也无法找到JDBC驱动程序？

$ grape --version

我正在处理一个示例 Ruby/Grape 示例，除了 json 被转义外，一切正常。我也是全新的 ruby​​ 及其框架（仅 3 天），如果这个问题是补救性的，那么很抱歉，并提前感谢您

我相当肯定不应该对引号进行转义，无论如何这里是转义的输出：

"{\"word\":\"test\",\"sentiment\":\"unkown\"}"

我的代码

require 'rubygems'
require 'grape'
require 'json'

class SentimentApiV1  < Grape::API
  version 'v1', :using => :path, :vendor => '3scale'
  format :json

  resource :words do
    get ':word' do
        {:word => params[:word], :sentiment => "unkown"}.to_json
    end

    post ':word' do
      {:word => params[:word], :result => "thinking"}.to_json
    end 
  end

  resource :sentences do
    get ':sentence' do
      {:sentence => params[:sentence], :result => "unkown"}.to_json
    end
  end

end

配置文件

$:.unshift "./app"

需要'sentimentapi_v1.rb'

运行 SentimentApiV1

包和版本

C:\Ruby-Projects\GrapeTest>bundle install …

我目前正在构建一个 API 来访问特定所有者的博客上的所有帖子。我想在博客模型下将它们显示为嵌套的 json。

class API < Grape::API
format :json
prefix "api"
resource "posts" do
  get ':id' do
    owner = Owner.find(params[:id])
    present owner.blogs.each do |b|
        present b
        b.posts.each do  |p|
            present p
        end
    end
  end
end
end

可以安全地假设所有者拥有许多博客，进而拥有许多帖子。

我希望有人解释为什么在Rails(4.1.8)和Grape(0.10.1)中发生这种情况

所以这是我的API:

app/api/root.rb:

module API
  class Root < Grape::API
    prefix 'api'
    mount API::V1::Root
  end
end

app/api/v1/root.rb:

module API::V1
  class Root < Grape::API
    version 'v1'
    mount API::V1::Users
  end
end

app/api/v1/users.rb:

module API::V1
  class Users < Grape::API
    format 'json'

    resource :users do
      desc "Return list of users"
      get '/' do
        User.all
      end
    end
  end
end

config/routes.rb:

Rails.application.routes.draw do
  mount API::Root => '/'
end

在我的application.rb添加中:

config.paths.add "app/api", glob: "**/*.rb"
config.autoload_paths += Dir["#{Rails.root}/app/api/*"]

在那种情况下,我收到错误: NameError: uninitialized constant API …
