如何避免验证、回调和“attr_accessible”使用 Ruby on Rails 3 进行播种过程有何影响？

我正在使用 Ruby on Rails 3，并尝试在我的应用程序数据库中播种数据。

在“RAILS_ROOT/models/user.rb”中，我有：

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”中，我有：

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

# Test2
User.find_or_create_by_email (
  :name       => "",
  :surname    => "",
  :email      => "[email protected]"
)

因此，在终端中运行，

rake db:seed

数据库当然不会填充数据，因为“attr_accessible”为零（案例测试1））并且验证未通过（案例测试2）。

我想在播种过程中跳过验证和“可访问属性的效果”。 这可能吗？如果是这样，该怎么做？

PS：我不想在“RAILS_ROOT/db/migrate/201....rb”代码中使用这样的代码：

execute "INSERT INTO users ( name, surname, email ) VALUES ( "Test1 name", "Test1 surname", "[email protected]")"

UPDATE

我需要还可以跳过所有回调。 可能吗？如果是这样，怎么办？

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      => "[email protected]"
)

# Test2
User.find_or_create_by_email (
  :name       => "",
  :surname    => "",
  :email      => "[email protected]"
)

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", "[email protected]")"

UPDATE

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

如果您检查 ActiveRecord 的文档，您会看到attributes= 方法有一个参数来启用此功能：

attributes=(new_attributes,guard_protected_attributes = true)

像这样使用它：

# Create a new user
@user = User.new

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

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

# Save the object
@user.save

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      => "[email protected]"
}

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

# Save the object
@user.save
