Rails 4 using strong parameters without controller

Question

Rails 4: I am coming out of rails 3.2.x And I have a question. How to use Strong parameter without controller.

I have this model:

Track (the only one that has a Controller  )
  has_many :tracksegments, :dependent => :destroy
  has_many :points, :through => :tracksegments
Tracksegment
  belongs_to :track
  has_many :points, :dependent => :destroy
points
  belongs_to :tracksegment

The track is the only one that has a controller, so it has some powerful parameters.

I want to know where I can put the parameters belonging to "tracksegment" and "points". In Rails 3.x it is hidden in the model, but in rails 4 I do not have a controller for them.

Answer 1

You enable parameters in which controller you send them. It looks like you are sending them through your track controller, if so you added them.
