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 %>
<% if column.human_name != "Image" %> <%= column.human_name %>: <%=h @team.send(column.name) %> <% else %> <%= image_tag url_for_file_column :"team", :"image" %> <% end %>
<% 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"
