Hi, first and foremost sorry if my english is not the best.
I want to choose between somo products in a view.
I have tickets and i wanna add tickets_products.
1)ruby script/generate scaffold ticket_product name:string
2) rake db: migrate
3) Models-> ticket belongs to ticketproducts and ticketproducts has
many tickets.
4) I use Sqlite Manager (firefox pluggin) and I added two ticket
products with this soft in tickets_products table.
5)I wrote this in new.html.erb (ticket view):
<% form_for(@ticket) do |f| %>
<table class="product" >
<tr>
<th><%= _('Product') %></th>
<th><%= _('Breakdown') %></th>
<th><%= _('State') %></th>
</tr>
<tr>
<td><%= f.collection_select :ticket_product_id, @ticket_products,
:id, :name, :prompt => _("Select product") %></td>
<td><%= f.collection_select :ticket_breakdown_id,
@ticket_breakdowns, :id, :title, :prompt => _("Select breakdown") %>
</td>
<td><%= f.collection_select :ticket_state_id, @ticket_states, :id,
:title, :prompt => _("Select state") %></td>
</tr>
</table>
The error is:
NoMethodError in Tickets#new
Showing tickets/new.html.erb where line #14 raised:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.map
Extracted source (around line #14):
11: <th><%= 'Estado del producto' %></th>
12: </tr>
13: <tr>
14: <td><%= f.collection_select :ticket_product_id,
@ticket_products, :id, :name, :prompt=> "Seleccione producto" %></td>
15: <td><%= f.text_field :ticket_breakdown_id %> </td>
16: <td><
--------------------------------
