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 %>
<% 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 might have expected an instance of Array.
The error occurred while evaluating nil.split"
And in app/controllers/admin/teams_controller.rb “Show” function is
absolutely same.
Are you defining Admin::TeamsController in that file?
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.

I assume that @team.image is perhaps nil?
Try this and see if you begin to understand what your code is doing:
<% if column.human_name != “Image” %> <%= column.human_name %>: <%=h @team.send(column.name) %>
<% elsif @team.image.nil? %> Oops! The image is nil
<% 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.
But to get it working I spent a
