Question

I’m using Ruby on Rails 3.0.7 and MySQL 5.1. I’d like to force to store the object id in a migration file. For example I have this:

User.create!(
  :name => 'Test name'
)

but I would like to do something like this:

User.create!(
  :id   => '12345', # Force to store the object data with id '12345'
  :name => 'Test name'
)

Note: the above code will not force the id value in the database.

Is it possible? If so, how?

Answer 1

You can’t mass assign the restricted fields like id. But you can individually set them:

user = User.new(:name => 'Test name')
user.id = 12345
user.save!

OR

User.create!(:name => 'Test name') do |user|
  user.id = 12345
end
