Rails控制檯：項目（表不存在？） - Sqlite3

我遇到了一個問題。我最近在github上克隆了一個應用程序，並嘗試使用Rails控制檯啓動它。當我輸入其中一個表的名字時，我收到了這條消息。Rails控制檯：項目（表不存在？） - Sqlite3

Project 
=> Project(Table doesn't exist)

這裏是Schema.rb文件

ActiveRecord::Schema.define(version: 20120504152649) do 

    create_table "projects", force: true do |t| 
    t.string "name" 
    t.string "point_scale",   default: "fibonacci" 
    t.date  "start_date" 
    t.integer "iteration_start_day", default: 1 
    t.integer "iteration_length", default: 1 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    t.integer "default_velocity", default: 10 
    end 

    create_table "projects_users", id: false, force: true do |t| 
    t.integer "project_id" 
    t.integer "user_id" 
    end 
end

這裏是項目遷移

class CreateProjects < ActiveRecord::Migration 
    def self.up 
    create_table :projects do |t| 
     t.string :name 
     t.string :point_scale, :default => 'fibonacci' 
     t.date :start_date 
     t.integer :iteration_start_day, :default => 1 
     t.integer :iteration_length, :default => 1 

     t.timestamps 
    end 
    end 

    def self.down 
    drop_table :projects 
    end 
end

的Gemfile中

source 'http://rubygems.org' 

ruby '2.1.0' 

gem 'rails', '4.0.2' 
gem 'sass-rails', '~> 4.0.1' 
gem 'uglifier', '>= 1.3.0' 
gem 'coffee-rails', '~> 4.0.1' 
gem 'jquery-rails' 
gem 'jbuilder', '~> 1.2' 
gem 'ejs' 
gem "compass-rails", "~> 1.1.2" 
gem "devise", "~> 3.2.0" 
gem 'transitions', '0.1.9', :require => ["transitions", "active_record/transitions"] 
gem 'rails-i18n' 
gem 'configuration' 
gem 'rails-observers', '~> 0.1.2' 
# gem 'protected_attributes' 
gem 'jquery-ui-rails' 

group :production do 
    gem 'pg' 
    # This helps with serving assets and log files on the heroku platform. 
    # See https://github.com/heroku/rails_12factor 
    # https://devcenter.heroku.com/articles/rails4#logging-and-assets 
    gem 'rails_12factor' 
end 

group :development, :test do 
    gem 'sqlite3' 
    gem 'rspec-rails' 
    gem 'factory_girl_rails' 
    gem 'jasmine', '~> 1.3.2' 
    gem 'capybara' 

    gem 'database_cleaner' 
end

這裏是我的database.yml文件

# SQLite 
development: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    pool: 5 
    timeout: 5000 

test: 
    adapter: sqlite3 
    database: db/test.sqlite3 
    pool: 5 
    timeout: 5000 

production: 
    adapter: sqlite3 
    database: db/production.sqlite3 
    pool: 5 
    timeout: 5000

我已經試過遷移數據庫

rake db:migrate 
=>undefined method `database_authenticatable' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x007fd7832ed418>/Users/richardhamilton/MyProjects/fulcrum/db/migrate/20110210082458_devise_create_users.rb:4:in `block in up'

我試圖創建數據庫

rake db:create 
db/development.sqlite3 already exists

我試着加載模式

rake db:schema::load 
rake aborted! 
Don't know how to build task 'db:schema::load'

我不不知道爲什麼它找不到一張桌子。

我假設你在嘗試啓動任何東西之前運行了基本的rake命令？ – MCBama

我剛剛嘗試過，併爲＃ /Users/richardhamilton/MyProjects/fulcrum/db/migrate/20110210082458_devise_create_users.rb:4：in'block in up'獲得了未定義的方法'database_authenticatable' –

什麼是你嘗試的「那個」？耙db：創建？ rake db：schema：load？哪一個？或兩者？ – MCBama

運行rake db:drop db:create db:schema:load您應該啓動並運行。
