Rails 4 Unpermitted Parameters for Array

Question

I have an array field in my model and I\'m attempting to update it.

My strong parameter method is below

def post_params
  params[\"post\"][\"categor         


        

Answer 1

Try this

params.require(:post).permit(:name, :email, :categories => [])

(Disregard my comment, I don't think that matters)
