Rails 迁移文件未将我定义的所有列添加到数据库中

我正在尝试创建一个 Rails 应用程序，但出了点问题，我收到了一个令人讨厌的错误 undefined methodtitle' for #`

我使用了这个 ling:

ruby script/generate scaffold Blog title:String body:text

来生成以下迁移文件：

class CreateBlogs < ActiveRecord::Migration
 def self.up
  create_table :blogs do |t|
    t.String :title
    t.text :body

    t.timestamps
  end
end

 def self.down
  drop_table :blogs
 end
end

检查数据库后发现没有“标题”列。我尝试过使用几个不同的名称，无论出于何种原因，即使迁移文件中有两列以及时间戳，在我运行 rake db:migrate 后，除了时间戳和 id 之外，只有一个字段。不知道为什么我的“标题”字段没有被创建:(

I'm trying to create a rails app, but somethings going wrong, I'm getting a nasty error undefined methodtitle' for #`

I've used this ling:

ruby script/generate scaffold Blog title:String body:text

to generate the following migration file:

class CreateBlogs < ActiveRecord::Migration
 def self.up
  create_table :blogs do |t|
    t.String :title
    t.text :body

    t.timestamps
  end
end

 def self.down
  drop_table :blogs
 end
end

Upon inspection of the database, there's no 'title' column. I've tried this with a few different names and for whatever reason, even though there's two columns along with the timestamps in the migration file, after I've run rake db:migrate there's only one field in addition to the timestamps and id. Not sure why my 'title' field isn't being created :(
