無法在腳手架後遷移psql數據庫 - Cloud9

Question

當我嘗試在我的psql數據庫上運行rake db：migrate時，出現「參數數量錯誤（給定爲1，預期爲0）」錯誤。 This asker有同樣的麻煩，但鎖定我的Gemfile「gem'arel'，'6.0.0.beta2'」和使用rails版本4.2.0.beta4還沒有解決問題，雖然我能捆綁，絕對是使用這些版本。任何幫助將非常感激！

以下是完整的跟蹤

rake db:migrate --trace

** Invoke environment (first_time) 
** Execute environment 
** Invoke db:load_config (first_time) 
** Execute db:load_config 
** Execute db:migrate

這裏是文件20161104230329_create_mytable.rb

class CreateTables < ActiveRecord::Migration 
    def change 
    create_table :mytable do |t| 
     t.name :string 
     t.param1 :integer 
     t.param2 :integer 
     t.param3 :integer 

     t.timestamps null: false 
    end 
    end 
end 

Answer 1

你有逆轉遷移領域/字段類型選項的順序。應該是

class CreateTables < ActiveRecord::Migration 
    def change 
    create_table :mytable do |t| 
     t.string :name 
     t.integer :param1 

     t.timestamps 
    end 
    end 
end
