[英]Rails migration file not adding all my defined columns to the db
I'm trying to create a rails app, but somethings going wrong, I'm getting a nasty error undefined method
title' for #` 我正在尝试创建一个Rails应用,但是出了点问题,我收到了#`的令人讨厌的错误
undefined method
title'
I've used this ling: 我用过这种灵:
ruby script/generate scaffold Blog title:String body:text
to generate the following migration file: 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
Upon inspection of the database, there's no 'title' column. 检查数据库后,没有“标题”列。 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.
我尝试了几种不同的名称,无论出于何种原因,尽管迁移文件中有两列以及时间戳,但在运行rake db:migrate之后,除了时间戳和id之外,只有一个字段。 Not sure why my 'title' field isn't being created :(
不确定为什么未创建我的“标题”字段:(
字符串不应该是小写的“ S”吗?
