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

I had the same problem, but simply adding array to permit was not enough. I had to add type, too. This way:

params.require(:transaction).permit(:name, :tag_ids => [:id])

I am not sure if this is perfect solution, but after that, the 'Unpermitted parameters' log disappeared.

I found hint for that solution from this excellent post: http://patshaughnessy.net/2014/6/16/a-rule-of-thumb-for-strong-parameters
