Question

I have the following code in a micropost_spec.rb:

  before(:each) do
    @user = Factory :user
    @attr = { :paragraphs => 4, :characters => 1000, :summary => "Recap of Event" }
  end

  it "should create a new instance given valid attributes" do
    @user.microposts.create!(@attr)
  end

And when I run my tests, I get the following error:

  Failure/Error: @user.microposts.create!(@attr)
  ActiveRecord::RecordInvalid:
     Validation failed: Id can't be blank

Is it possible to see if the id is set inside the rails console?

Answer 1

Your model is probably trying to validate that id is present with something like validates_presence_of :id or validates :id, :presence => true. You shouldn’t do that, as validations on new records are always run before the record is saved to the database and assigned an id.
