Multi-dimensional array in strong_params

I am trying to accept a multi-dimensional array using strong_params.

I was using: 

params.require(:name).permit(array_param: [])

and it was working fine for regular arrays.

Now I got a multi-dimensional array format I have to deal with. The previous solution is not working for the following case.

[[1],[2],[2,1]]

I would gladly appreciate some guidance. Thanks!

You need to take the long route and do it like this

def permitted_params
  permitted = params.require(:name)

  if params[:name][:array_param].present?
    permitted[:name][:array_param] = params[:name].require(:array_param)
  end

  permitted
end
