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"

Are you defining Admin::TeamsController in that file?

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.

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
