Undefined Method attr_accessible

Question

I am somewhat new to rails and I am trying to create a User login. I went through the tutorial found here. At the end it had me add \"attr_accessible\" for mass assignment

Answer 1

No mass assignment allowed for Rails 4.1

You will have to try something like this.

class Person
  has_many :pets
  accepts_nested_attributes_for :pets
end

class PeopleController < ActionController::Base
  def create
    Person.create(person_params)
  end

  ...

  private

    def person_params
      # It's mandatory to specify the nested attributes that should be whitelisted.
      # If you use `permit` with just the key that points to the nested attributes hash,
      # it will return an empty hash.
      params.require(:person).permit(:name, :age, pets_attributes: [ :name, :category ])
    end
end
