这是我的第一个Sinatra项目 - 链接缩短但我遇到了一些错误,说实话,sinatra的内置调试器几乎没有告诉我。我希望你能给我一些线索或建议解决问题的方法。

require 'sinatra'
require 'shotgun'
require 'data_mapper'
require 'dm-migrations'
require 'dm-sqlite-adapter'
DataMapper::setup(:default, "sqlite3://#{Dir.pwd}/form.db")
class Url
include DataMapper::Resource
property :id, Serial
property :url, String
property :suggestion, String
end
get '/' do
erb :index
end
post '/' do
Url.create(:url => params[:url], :suggestion=> params[:suggestion])
end
get '/Url.suggestion' do
query = request_path.slice!(0)
redirection = Url.first(:suggestion => query)
redirect redirection.url
end

这是因为您需要完成模型。请参阅“最终模型”标题下的http://datamapper.org/getting-started.html。
在定义模型后添加finalize命令:
class Url
include DataMapper::Resource
property :id, Serial
property :url, String
property :suggestion, String
end
# add this line
DataMapper.finalize
