Question

我正在使用Sinatra和ActiveRecord创建一个网站。每当我运行我的网站时，我都会收到错误

Boot Error

Something went wrong while loading config.ru

NoMethodError: undefined method `get' for #<Class:0x007f8b646d8818>

这是我的app.rb

require 'bundler'
Bundler.require

require "sinatra"
require "sinatra/activerecord"

set :database, "sqlite3:///events.db"

class Contact < ActiveRecord::Base

    validates_uniqueness_of :first
    validates_presence_of :first

    validates_uniqueness_of :last
    validates_presence_of :last

    validates_uniqueness_of :email
    validates_presence_of :email

    get '/' do
        erb :index 
    end

    get '/weddings.erb' do
        erb :weddings
    end

    get '/birthdays.erb' do
        erb :birthdays
    end

    get '/anniversaries.erb' do
        erb :anniversaries
    end

    get '/about.erb' do
        erb :about
    end

    get '/contacts/new' do
        @contact = Contact.new
        erb :contact
    end

    post '/contacts' do
        @contact = Contact.new(params[:rabbit])
        if @contact.save
            status 201
            redirect '/' + @contact.id.to_s
        else
            status 400
            erb :contact
        end
    end

end

这是我的config.ru

require "./app"
run Sinatra::Application

任何人都知道问题是什么？

Answer 1

您已经从ActiveRecord::Base继承了数据库模型。将您的路由放在继承自Sinatra::Base的类中，并确保require 'sinatra/base'。
