如何避免在使用Ruby on Rails 3的种子过程中的验证，回调和'attr_accessible'效果？ [英] How to avoid the validation, callbacks and 'attr_accessible' effects during the seeding process using Ruby on Rails 3?

问题描述

在'RAILS_ROOT / models / user.rb'中我有：。我使用Ruby on Rails 3，我试图在我的应用程序数据库中种子数据。

  class User< ActiveRecord :: Base 
 attr_accessible #none 
 
 validates：name，
：presence => true 
 validates：surname，
：presence => true 
 validates：email，
：presence => true 
 end 
  

在RAILS_ROOT / db / seeds.rb p>

 ＃Test 1 
 User.find_or_create_by_email（
：name =>Test1 name，
：surname =>Test1 surname，
：email =>[e-mail]1
）
 
＃Test2 
 User.find_or_create_by_email 
：name =>，
：surname =>，
：email =>[e-mail]2
）
  

因此，在终端中运行

  rake db：seed 
  

当然，数据库不会填充数据，因为'attr_accessible'到nil（Case Test1）和验证未通过（Case Test2）。

我想在播种期间跳过验证和attr-访问效果 有可能吗？

PS：我不想使用'RAILS_ROOT / db / migrate / 201 .... rb '代码如下：

 执行INSERT INTO用户（姓名，电子邮件）VALUES（Test1 name，Test1 surname，[e-mail]1）

UPDATE

我还需要略过所有回拨。 是可能吗？如果是，如何检查

解决方案

org / classes / ActiveRecord / Base.html＃method-i-attributes％3Drel =noreferrer> ActiveRecord的文档，您将看到 attributes = 方法具有启用此功能的参数：

attributes =（new_attributes，guard_protected_attributes = true）

使用它像这样：

 ＃创建一个新用户
 @user = User.new 
 
＃用户的属性
 @attrib = {
：name => Test1 name，
：surname => Test1 surname，
：email => [e-mail]1
} 
 
＃使用'send'调用对象的attributes =方法
 @ user.send：attributes =，@attrib，false 
 
＃保存对象
 @ user.save

I am using Ruby on Rails 3 and I am trying to seed data in my application database.

In 'RAILS_ROOT/models/user.rb' I have:

class User < ActiveRecord::Base
  attr_accessible #none

  validates :name,
    :presence => true
  validates :surname,
    :presence => true
  validates :email,
    :presence => true
end

In 'RAILS_ROOT/db/seeds.rb' I have:

# Test 1
User.find_or_create_by_email (
  :name       => "Test1 name",
  :surname    => "Test1 surname",
  :email      => "[e-mail]1"
)

# Test2
User.find_or_create_by_email (
  :name       => "",
  :surname    => "",
  :email      => "[e-mail]2"
)

So, running in the Terminal

rake db:seed

of course the database will NOT populate with datas because 'attr_accessible' to nil (Case Test1) and validation not passed (Case Test2).

I would like to skip the validation and "attr-accessible effects" during the seeding process. Is it possible? If so, how to do that?

P.S.: I don't want to use in 'RAILS_ROOT/db/migrate/201....rb' code like this:

execute "INSERT INTO users ( name, surname, email ) VALUES ( "Test1 name", "Test1 surname", "[e-mail]1")"

UPDATE

I need also to skip all callbacks. Is it possible? If so, how?

解决方案

If you check ActiveRecord's documentation you'll see the attributes= method has a parameter to enable this:

attributes=(new_attributes, guard_protected_attributes = true)

Use it like this:

# Create a new user
@user = User.new

# Attributes for the user
@attrib = {
  :name       => "Test1 name",
  :surname    => "Test1 surname",
  :email      => "[e-mail]1"
}

# Use 'send' to call the attributes= method on the object
@user.send :attributes=, @attrib, false

# Save the object
@user.save
