How to retrieve auto incremented id in rails 4.1?

Currently i am working on rails 4.1,

I have a model called accounts.rb,

account = Account.create :name => 'test' :info => 'test'

So this statement is saving to database, Then i am using "account.id" which auto increment id in accounts table.

But that is not working and showing following error,

undefined method `id' for "":String

But this was worked in rails 1.9 version .

Please help me.

Object

Your method seems correct; your syntax seems to have an issue

undefined method `id' for "":String

This basically means you're calling the id method on an object which is just a string, an empty one at that.

I would therefore say the problem is not to do with your auto increment number, it's to do with how you're calling the id of the new object

Create

The standard way to do this would be to use the following:

#controller
account = Account.create({name: "test", info: "test"})
return account.id

According to the create documentation, this should work for you. If it doesn't, you may wish to use the .new with .save methods, like this:

#controller
account = Account.new({name: "test", info: "test"})
if account.save
  return account.id
end
