/Users/sayedgamal/apps/test/config/boot.rb:20:Warning: Gem::SourceIndex#search support for String patterns is deprecated
== CreatePeople: migrating ====================================================
-- create_table(:people)
rake aborted!
undefined method `string' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x238e97c>

当我发出这个错误时，我收到了这个错误

rake 数据库：迁移

命令..在我的rails项目的根文件夹中..

migrate/001_create_people.rb 内容：

class CreatePeople < ActiveRecord::Migration
  def self.up
    create_table :people do |t|
     t.string :first_name
     t.string :second_name
     t.string :company
     t.string :email
     t.string :phone
    end
  end

  def self.down
    drop_table :people
  end
end

注意：我还使用了整数和文本字段，但它不起作用.. 错误总是更改为未定义的数据类型 {string, integer, text ,...} 基于迁移文件中输入的内容..！注意：我在应用程序的根文件夹中使用 rake db:migrate 。

原文

(in /Users/sayedgamal/apps/test)
/Users/sayedgamal/apps/test/config/boot.rb:20:Warning: Gem::SourceIndex#search support for String patterns is deprecated
== CreatePeople: migrating ====================================================
-- create_table(:people)
rake aborted!
undefined method `string' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x238e97c>

(See full trace by running task with --trace)

I get that error when I'm issuing the

rake db:migrate

command .. in the root folder of my rails project ..

migrate/001_create_people.rb contents :

class CreatePeople < ActiveRecord::Migration
  def self.up
    create_table :people do |t|
     t.string :first_name
     t.string :second_name
     t.string :company
     t.string :email
     t.string :phone
    end
  end

  def self.down
    drop_table :people
  end
end

Note: that I also used the integer and text fields and it didn't work ..
Error always changes to undefined datatype {string, integer, text ,...}
based on the typed in the migration file .. !
Note: I'm using the rake db:migrate in the root folder of the app.

检查您的 Rails 版本。当Sexy Migrations 插件合并到核心中时，这种“t.string”语法就出现在rails 中。如果无法升级到最新版本，则应使用

t.column :first_name, :string

语法。

Check your version of rails. This "t.string" syntax came to rails when the Sexy Migrations plugin was merged into the core. If you cannot upgrade to the latest version, you should use
