Hi everyone, looking for some help with this error below. It seems
that althought it finds the product_line_id attribute, the code
doesn''t find the product_line''s name attribute. I''ve
already declared
the has_many: call_driver relationship in the product_line model, and
the belongs_to: product_line relationship in the call_driver model.
It also works in the console, oddly enough, but not in the view.
I know I''m missing something elemental here, but I haven''t the
faintest clue what it is.
###
NoMethodError in Admin#index
Showing admin/index.html.erb where line #13 raised:
You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.name
Extracted source (around line #13):
10: <% for driver in @driver %>
11: <tr>
12: <td><%=h driver.name %></td>
13: <td><%=h driver.product_line.name %></td>
14: <td><%= link_to ''Edit'', {:action =>
''driver_edit''} %>
15: <%= link_to ''Destroy'', {:action =>
''driver_delete'',:id =>
driver.id} %>
16: </td>
###
admin_controller has this for the index action;
def index
@driver = CallDriver.find(:all)
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @driver }
end
end

What''s interesting is that I''ve done almost entirely the same
thing
with another view, and it works;
###### View
<% for driver in @drivers %>
<tr>
<td><%= driver.name %></td><td>
<%= driver.product_line.name %>
</td>
</tr>
<% end %>
###### Controller
class ShowController < ApplicationController
def show_drivers
# Find Call Drivers
@drivers CallDriver.find(:all, :conditions => [
''product_line_id = :product_line and
sub_product_line_id = :sub_product_line and
platform_id = :platform and
consolidation_id = :consolidation and
segment_id = :segment'',
{:product_line => params[:product_line],
:sub_product_line => params[:sub_product_line],
:platform => params[:platform],
:consolidation => params[:consolidation],
:segment => params[:segment]}])
respond_to do |format|
format.html
format.xml { render :xml => @drivers }
end
end
end

Please disregard, I''ve discovered the problem. I''m an idiot and forgot that some of my data didn''t have a product_line_id set.
