I''m newbie. Please, help. I suppose it''s easy :)
I have admin controller which is working ok and with usual controller
I
have trouble.
This is app/controllers/team_controller.rb
____________________________________________
class TeamController < ApplicationController
def show
@team = Team.find(params[:id])
end
end
___________________________________________
And in app/controllers/admin/teams_controller.rb "Show" function is
absolutely same. Then, app/views/admin/teams/show.rhtml looks like
<% for column in Team.content_columns %>
<p>
<% if column.human_name != "Image" %>
<b><%= column.human_name %>:</b> <%=h
@team.send(column.name) %>
<% else %>
<%= image_tag url_for_file_column :"team", :"image"
%>
<% end %>
</p>
<% end %>
But when I try to use this code in app/views/team/show.rhtml I get an
error:
" Showing app/views/team/show.rhtml where line #6 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.split"

Try this and see if you begin to understand what your code is doing: <% if column.human_name != "Image" %> <b><%= column.human_name %>:</b> <%=h @team.send(column.name) %> <% elsif @team.image.nil? %> <span>Oops! The image is nil</span> <% else %> <%= image_tag url_for_file_column :"team", :"image" %> <% end %> You really should understand what''s happening with the scaffold code (and replace it with your actual code, scaffolding isn''t meant to be permanent!) before you go inviting plugins like file_column to the party. -Rob Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks a lot. One check made role. P.S. plugin also is working fine ;) But to get it working I spent a lot of time On 13 янв, 23:15, Rob Biedenharn <R...-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org> wrote:> On Jan 13, 2008, at 3:51 PM, sublime wrote: > > > I''m newbie.
