Rails 4 object not saving when rendering form in another model

Question

I have a Call model nested under Contact, a Contact has many calls. In the Edit#Contact view, I'm rendering the form to create a new call. When I submit the form, params are getting submitted, but the new Call object is not saved.

Note that if I just create a new Call from the New#Call view (form not rendered in Edit#Contact view), then the Call object is saved, so it's only a problem when rendering the form in the Edit Contact view.

console output:

Here is the updated form partial, rendered in contact#edit:

= form_for [Contact.find(params[:id]), Contact.find(params[:id]).calls.new], :url => url_for(controller: "Call", action: "create") do |f|
  .form-group
    = f.label :dial
    = f.select :dial_id, options_from_collection_for_select(Dial.all, "id", "result"), class: 'form-control'
  .form-group
    = f.label :conversation
    = f.select :conversation_id, options_from_collection_for_select(Conversation.all, "id", "result")
  .form-group
    = f.label :investing
    = f.select :investing_id, options_from_collection_for_select(Investing.all, "id", "result")
  .form-group
    = f.label :timing
    = f.select :timing_id, options_from_collection_for_select(Timing.all, "id", "result")
  .form-group
    = f.label :motivator
    = f.select :motivator_id, options_from_collection_for_select(Motivator.all, "id", "result")
  .actions
    = f.submit 'Save', class: 'btn btn-success btn-sm'

Rendering the new call form in contact#edit view like this:

= render 'calls/form'

As a side question, I wasn't able to figure out the form_for path for this. So to tackle one problem at a time, I just have the very wordy path as a placeholder.

Here is the edit method in the Contacts Controller:

  def edit
    @contact = Contact.find(params[:id])
    @user = @contact.user
    @new_call = @contact.calls.build
    authorize @contact
  end

create method in the Call Controller:

def create
    @contact = Contact.find(params[:contact_id])
    @call = Call.new(call_params)
    @call.contact_id = @contact.id
    @call.user_id = current_user.id

    if @call.save
      flash[:notice] = "Your Call was successfully posted."
      redirect_to edit_contact_path(@contact)
    else
      flash[:error] = "Your Call was not posted. Please try again."
      redirect_to edit_contact_path(@contact)
    end
  end

routes.rb:

  resources :contacts do
    resources :properties
    resources :calls

    collection do
      post :import
      get :database
    end
  end
