Rails fields_for form not showing up, nested form

I have created an simple rails project. All worked fine until I tried to add a new model

Paintings
that
belongs_to
treatment and an
Patient
that
has_many
Paintings through Treatment. So somehow the nested form I created does not show up, I believe it has to do with the controller! Thanks, and greetings from Germany!

Treatments controller:

class TreatmentsController < ApplicationController
def create
@patient = Patient.find(params[:patient_id])
@treatment = @patient.treatments.create(params[:treatment])
redirect_to patient_path(@patient)
end

def destroy
@patient = Patient.find(params[:patient_id])
@treatment = @patient.treatments.find(params[:id])
@treatment.destroy
redirect_to patient_path(@patient)
end
end


And the form for treatments with
nested fields_for
that doesn't show up:

<%= form_for([@patient, @patient.treatments.build]) do |f| %>
<div class="field">
<%= f.label :content %>
<%= f.text_area :content, :cols => "30", :rows => "10" %>
</div>
<div class="field">
<%= f.label :category_id %>
<%= f.collection_select :category_id, Category.find(:all), :id, :typ %>
</div>

<%= f.fields_for :paintings do |ff| %>
<div class="field">
<%= ff.label :name, 'Tag:' %>
<%= ff.text_field :name %>
</div>
<% end %>

<div class="field">
<%= f.submit nil, :class => 'btn btn-small btn-primary' %>
</div>
<% end %>


UPDATE:

Show Site:

<% @patient.treatments.each do |treatment| %>
<tr>
<td><%= treatment.category.try(:typ) %></td>
<td><%= treatment.content %></td>
<td><%= treatment.day %></td>
<td><div class="arrow"></div></td>
</tr>
<tr>

Answer

Please try

= f.fields_for :paintings, Painting.new do |p|
