Question

I’m working on a map for the network in my building. I have the separate floor models working, which list each switch when you click on the show method. Then I would like to have it so you can click on each switch to see the jack numbers on each switch port. I have the view for the switch working thanks to another question I’ve asked, but now I’m stuck trying to show the jacks in that same show. Here is my partial for the jacks (app/views/jacks/_jacks.html.erb):

<%= form_for <WhatDoIPutHere?> do |f| %>
  <div class="field">
    <%= f.label :number %><br />
    <%= f.text_field :number %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

Now I know I need to run a rake routes to figure out the path.
Here is my rake routes result:

floor_switch_jacks GET    /floors/:floor_id/switches/:switch_id/jacks(.:format)         jacks#index
                   POST   /floors/:floor_id/switches/:switch_id/jacks(.:format)          jacks#create
new_floor_switch_jack GET    /floors/:floor_id/switches/:switch_id/jacks/new(.:format)      jacks#new

 floor_switch_jack GET    /floors/:floor_id/switches/:switch_id/jacks/:id(.:format)      jacks#show
                   PUT    /floors/:floor_id/switches/:switch_id/jacks/:id(.:format)      jacks#update
                   DELETE /floors/:floor_id/switches/:switch_id/jacks/:id(.:format)      jacks#destroy
    floor_switches GET    /floors/:floor_id/switches(.:format)                           switches#index

  new_floor_switch GET    /floors/:floor_id/switches/new(.:format)                       switches#new

      floor_switch GET    /floors/:floor_id/switches/:id(.:format)                       switches#show
                   PUT    /floors/:floor_id/switches/:id(.:format)                       switches#update
                   DELETE /floors/:floor_id/switches/:id(.:format)                       switches#destroy
            floors GET    /floors(.:format)                                              floors#index
                   POST   /floors(.:format)                                              floors#create
         new_floor GET    /floors/new(.:format)                                          floors#new
        edit_floor GET    /floors/:id/edit(.:format)                                     floors#edit
             floor GET    /floors/:id(.:format)                                          floors#show
                   PUT    /floors/:id(.:format)                                          floors#update
                   DELETE /floors/:id(.:format)                                          floors#destroy
        home_index GET    /home/index(.:format)                                          home#index
              root        /                                                              home#index

My question is how do I read the rake routes to find the proper syntax for the form_for line? I had this same problem getting my switch view to work in the first place. If this is an easy question and there is a guide out there feel free to just send me to that instead. I can’t seem to find one specific to to this.

Thanks in advance for any help!

EDIT:

class JacksController < ApplicationController

  def create
    @switch = Switch.find(params[:switch_id])
    @jack = @switch.jacks.create(params[:jack])
    redirect_to switch_path(@switch)
  end

  def destroy
    @switch = Switch.find(params[:switch_id])
    @jack = @switch.jacks.find(params[:id])
    @jack.destroy
    redirect_to switch_path(@switch)
  end

end

You can have nested forms for your nested models.

form_for @floor do |f|
  f.fields_for :switches do |g|
    g.fields_for :jacks do |h|
      h.label :number
    end
  end
end
