Question

I have 2 models, clients and client_prices, I would like to have 2 client prices nested forms sections in the client’s show page. 1 nested form would be for non-custom prices and another for custom prices. The non-custom (custom == false) prices would only have the “custom” attribute available to edit. The “Custom Prices” would have all of the attributes available to edit.

I’ve tried a few different approaches, but I don’t know where to put the conditional logic to make this work correctly. I’m using simple_form to generate the forms, but I’m not married to it.

Controllers

class Client < ActiveRecord::Base
    attr_accessible :name, :client_prices_attributes
    has_many :client_prices
    accepts_nested_attributes_for :client_prices, :allow_destroy => true

end


class ClientPrice < ActiveRecord::Base
  attr_accessible :client_id, :price, :visit_type, :id, :custom

  belongs_to :client
  belongs_to :default_price

end

Client Show page

<%= simple_nested_form_for @client do |f| %>
    <%= f.fields_for :client_prices do |def_price_form| %>
        non-custom prices form here
    <%end%>
    <%= f.fields_for :client_prices do |def_price_form| %>
        custom prices form here
    <%end%>
<%end%>

Answer 1

Try the following:

<%= simple_nested_form_for @client do |f| %>
  <%= f.fields_for :client_prices do |def_price_form| %>
    <%= if def_price_form.object.custom %>
      Here you fields for custom form      
    <% end %>
  <% end %>
<% end %>
