New Rails User stuck on tutorial => Updating Posts/Mass Assignment

Hey guys, I've just started with Rails. I'm going through the getting
started tutorial, and I'm running into this error:
ActiveModel::MassAssignmentSecurity::Error in PostsController#update
I know it has to do with the new update and the whitelist attributes,
but I don't have the first idea how to fix it.

Any help would be extremely appreciated!

add

attr_accessible :my_attribute_name.....

to your model.rb file

Thank you!!

Hi,

yes, I had the same problem yesterday, and I'm also going through a
tutorial - maybe the same one?

Solved with 2 steps: added attr_accessible as mentioned earlier
message. Also I had to change the RSpec tests from

  before
    @user = User.new(name:"Example", email:"example@gmail.com").tap do

u>

        u.password = "foobar"
        u.password_confirmation = "foobar"
      end
  end

isnted of
  before
    @user = User.new(name:"Example", email:"example@gmail.com",
password = "foobar", password_confirmation = "foobar")
  before

and npw MassAssignment erros has gone.
