I show customer and in the same view I need a form to create a
delivery and a document associated to that customer:
This is customer show view:
<p>
<b><%= Customer.human_attribute_name("year") %>:</b>
<%= @customer.year %>
</p>
<p>
<b><%= Customer.human_attribute_name("code") %>:</b>
<%= @customer.code %>
</p>
<p>
<b><%= Customer.human_attribute_name("full_name") %>:</b>
<%= @customer.full_name %>
</p>
<p>
<b><%= Customer.human_attribute_name("birth_date") %>:</b>
<% if @customer.birth_date %>
<%= l @customer.birth_date %>
<% else %>
<%= @customer.birth_date %>
<% end %>
</p>
<% content_for :delivery_form do %>
<%= render 'deliveries/form' %>
<% end %>
<% content_for :delivered do %>
<p>
<% if @delivery.valid? and @document.valid? %>
<% for product in @customer.deliveries.last.products %>
<%= product.description %><br />
<% end %>
<% end %>
</p>
<p class="rightText">
<button id="print_button">stampa</button>
</p>
<% end %>
The delivery_form partial is:
<%= simple_form_for([@customer, @delivery]) do |f| %>
<p>
<%= f.input :delivered_at, :as => :hidden, :input_html => {
:value => Date.today } %>
</p>
<p>
<% for product in @products %>
<%= check_box_tag 'delivery[product_ids][]', product.id,
@delivery.products.include?(product) %>
<%= product.description %><br />
<% end %>
<%= f.error :products%>
</p><br />
<%= simple_fields_for @document do |doc| %>
<p>
<%= doc.label :doc_type %>:<br />
<%= doc.text_field :doc_type %>
<%= doc.error :doc_type %>
</p>
<p>
<%= doc.label :doc_number %>:<br />
<%= doc.text_field :doc_number %>
<%= doc.error :doc_number %>
</p>
<p>
<%= doc.label :issued_by %>:<br />
<%= doc.text_field :issued_by %>
<%= doc.error :issued_by %>
</p>
<% end %>
As you see I need @delivery and @document object and for that in the
customer show action I've to do
def show
@customer = Customer.find(params[:id])
@delivery = Delivery.new
@document = Document.new
@products = Product.all
end
