Rails console, saving objects

I was reading a book and following the instructions in it.

>> class Story < ActiveRecord::Base; end
=> nil
>> story = Story.new
=> #<Story id: nil, name: nil, url: nil, created_at: nil, updated_at: nil>
>> story.class
=> Story(id: integer, name: string, link: string, created_at: datetime, updated_at: datetime)

I do not remember me asking for id, name, link or url, created_at and updated_at. Is there a way to check if I asked?

I do know if I typed craeted_at instead of created_at or updetad_at instead of updated_at. Is there a way to check whether I typed it right or wrong?

From the Rails console, I had to create a story class, one instance of it and save the object, but I created two, so I got a 2 output for a story.id input. How do I remove the second object from the database?

Check out your migration in db/migrate.
There should be one called "create_stories" or something similar.

You can change that file and then rerun the migrations with 'rake db:reset'.

If you want to delete an object, just call the destroy on it or via the class:

# delete an instance
story = Story.find(2)
story.destroy
 
# delete via class method
Story.destroy(2)
 
# Both do the exact same thing
