rake db：migrate rake aborted！ StandardError：发生错误

Question

如果有人能够帮助至少了解问题可能来自何处，将不胜感激。

我在使用我正在处理的项目迁移时遇到了问题。我甚至开始了一个全新的问题，但问题仍然保持不变。出现在尝试执行rake数据库的错误消息：migrate （已尝试使用默认数据库-sqlite3和optional-postgresql启动新项目），但是，在生成模型后（使用rails g scaffold同时尝试）计划名称：名称dep_date ：datetime和只是模型 - rails g model调度名称：name dep_date：datetime）迁移停留。

迁移本身是：

class CreateSchedules < ActiveRecord::Migration[5.0] 
    def change 
    create_table :schedules do |t| 
    t.name :name 
    t.datetime :dep_date 
    t.timestamps 
    end 
end 
end 

命令：rake db:migrate:status

给出以下：

database: travel_t_challenge_development 

Status Migration ID Migration Name 

down 20160809121048 Create schedules 

命令：

rake db:migrate 

rake RAILS_ENV=production db:migrate or 

rake db:migrate:up VERSION=20160809121048 or 

bundle exec rake db:migrate VERSION=20160809121048 

（或重做）

导致了同样的错误：

掉落及建立/创建数据库再次表现也毫无帮助。

系统配置

Rails的版本：5.0.0 红宝石版本：2.2.3

试试这个，更换CreateSchedules迁移的变化的方法。

def change 
    create_table :schedules do |t| 
    t.string :name 
    t.datetime :dep_date 
    t.timestamps null: false 
    end 
end
