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. I do know if I typed craeted_at instead of created_at or
updetad_at instead of updated_at. How do I 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?

At some point you must have created a “stories” table in your database
with those fields. Rails (technically ActiveRecord) finds this based
on the name of your class (singular version of the table by default).

It should complain about the method not being there.

Story.destroy(2)

Note that that ‘2’ is the id of the record you want to remove. Has
nothing to do with it being the ‘second’ object.
