Creating new nested model in RoR

i am pretty new in RoR and trying to understand the basics. I have two models

 class Beekeeper < ActiveRecord::Base
    has_many :apiaries, dependent: :destroy 
 end

and

 class Apiary < ActiveRecord::Base
   belongs_to :beekeeper
 end

The controller for the Beekeepers is working just fine, but i have trouble routing to the 'new' route for apiary creation.

The apiaries controller is

 class ApiariesController < ApplicationController

      def new
      @beekeeper = Beekeeper.find(params[:beekeeper_id] )
      @apiary = @beekeeper.apiaries.build
      respond_to do |format|
        format.html { render new }
      end
      end


   private

   def apiary_params
        params.require(:apiary).permit(:name, :location, :numberofbeehives, :beekeeper_id)
   end
   end

Also in beekeepers controller we have a

      def current_beekeeper
          @current_beekeeper ||= Beekeeper.find_by(id: session[:beekeeper_id])
      end

I am using 'application.html.erb' for rendering a header and a footer in all pages. The first problem is in the '_header.html.erb':

       <% if logged_in? %>
    <li><%= link_to "Insert Apiary", new_beekeeper_apiary_path(@beekeeper) %></li>
      <li><%= link_to "All Beekeepers", beekeepers_path %></li>

        <li><%= link_to "Profile", beekeeper_path(@beekeeper) %></li>
        <li><%= link_to "Settings", '#' %></li>
        <li>
          <%= link_to "Log out", logout_path, method: "delete" %>
        </li>
      </ul>

If in the links for 'profile' and 'new_apiary' i include (@beekeeper) i get a: $No route matches {:action=>"new", :beekeeper_id=>nil, :controller=>"apiaries"} missing required keys: [:beekeeper_id]$

If in the above links i include instead of $@beekeeper$ -> $current_beekeeper$ (or just current_beekeeper dunno why) the pages load just fine but then when i click on the new apiary link i get either (Couldn't find Beekeeper with 'id'=) if i use $ @beekeeper = Beekeeper.find(params[:id] ) in my apiaries controller or a stack too deep error (it is recursing around lines 4 and 5 of the controller) if i use $ @beekeeper = Beekeeper.find(params[:beekeeper_id] )$ which i think should work.

Forgot to mention my routes files is

     Rails.application.routes.draw do

     resources :beekeepers do
          resources :apiaries
     end
     end

and i do have a beekeeper_id field in my apiaries db. Thanks for any help !
