I'm having trouble understanding nested resources. There is a Service scaffold, and there is Symptom model. I wanted to be able to add the symptom_item string to the service scaffold.
This is my current show template code:
<% if @service.symptoms.any? %>
<% @service.symptoms.each do |symptom| %>
<li><%= symptom.symptom_item %></li>
<% end %>
<% else %>
<p>
none
</p>
<% end %>
Here is my form code:
<%= form_for(@service) do |f| %>
<% if @service.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@service.errors.count, "error") %> prohibited this service from being saved:</h2>
<ul>
<% @service.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :s_text %><br>
<%= f.text_area :s_text %>
</div>
<div class="field">
<%= f.label :img_text %><br>
<%= f.text_field :img_text %>
</div>
<%= f.fields_for :symptoms do |builder| %>
<div class="field">
<%= builder.label :symptom_item %><br>
<%= builder.text_field :symptom_item, :rows => 3 %>
</div>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Here is my controller code that allow the symptom_attributes:
def service_params
params.require(:service).permit(:name, :s_text, :img_text, symptom_attributes: [:id, :service_item])
end
I know the problem is in the show template. When I write something as simple as:
= @service.symptoms
it gives me something funky like this:
#<Symptom::ActiveRecord_Associations_CollectionProxy:0x000000095295c8>
Does anyone see what's wrong with my code in the show template or maybe some where else?
Here are my models just in case:
class Service < ActiveRecord::Base
has_many :symptoms
accepts_nested_attributes_for :symptoms, allow_destroy: true
end
class Symptom < ActiveRecord::Base
belongs_to :service
end
