How to see a different content?

Rails
1

L’action create of deliveries controller is:

def create
@customer=Customer.find(params[:customer_id])
@delivery = @customer.deliveries.build(params[:delivery])
@document = @customer.build_document(params[:document])
if @delivery.valid? and @document.valid?
Delivery.transaction do
@delivery.save!
@document.save!
end
flash[:success] = ‘Ok’
respond_with(@customer)
else
@products = Product.all
render ‘customers/show’, :layout => ‘delivery’
end
end

l’action show of customers controller is:

…
<% content_for :delivery_form do %>
<%= render ‘deliveries/form’ %>
<% end %>
<% content_for :delivered do %>
<%= render ‘delivered/form’ %>
<% end %>

I want to see only one of the two content_for depending on @delivery
and @document are saved or not.
I have a form, on submit @delivery and @document are created, if they
are not valid I have to see the show view and in the layout I should
see <%= yield :delivery_form %> while if the objects are valid eand
then saved in the database in the layout I should see <%= yield
:delivered %>.
Based on what I can make the selection?

You could set an @variable in the controller action and test this in
the view to decide what to show.

Can’t I test if an object is saved or not in the database?

Well an unsaved object will have an id of nil.

or you can use the “.new_record?” method.

Do you mean test whether it is saved ok in the create action? You
know whether it saved ok by the path it took through the action.

It’ s not the solution.
After I’ve saved @document and @delivery I go to show action where I
have @delivery=Delivery.new and @document=Document.new, so new_record
is always true.

In the show action you should be finding the records in the database,
not making new ones. Otherwise how are you going to show them?

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:

<%= Customer.human_attribute_name("year") %>: <%= @customer.year %>

<%= Customer.human_attribute_name("code") %>: <%= @customer.code %>

<%= Customer.human_attribute_name("full_name") %>: <%= @customer.full_name %>

<%= Customer.human_attribute_name("birth_date") %>: <% if @customer.birth_date %> <%= l @customer.birth_date %> <% else %> <%= @customer.birth_date %> <% end %>

<% content_for :delivery_form do %>
<%= render ‘deliveries/form’ %>
<% end %>

<% content_for :delivered do %>

<% if @delivery.valid? and @document.valid? %> <% for product in @customer.deliveries.last.products %> <%= product.description %>
<% end %> <% end %>

stampa

<% end %>

The delivery_form partial is:

<%= simple_form_for([@customer, @delivery]) do |f| %>


<%= f.input :delivered_at, :as => :hidden, :input_html => {
:value => Date.today } %>



<% for product in @products %>
<%= check_box_tag ‘delivery[product_ids][]’, product.id,
@delivery.products.include?(product) %>
<%= product.description %>

<% end %>
<%= f.error :products%>



<%= simple_fields_for @document do |doc| %>


<%= doc.label :doc_type %>:

<%= doc.text_field :doc_type %>
<%= doc.error :doc_type %>



<%= doc.label :doc_number %>:

<%= doc.text_field :doc_number %>
<%= doc.error :doc_number %>



<%= doc.label :issued_by %>:

<%= doc.text_field :issued_by %>
<%= doc.error :issued_by %>


<% 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
