I am working on a web app that attaches to a MySQL database.

I can add users through the admin\_controller just fine without  
“before\_filter :authorize”

I need that statement obviously. When I try to login with my admin  
password I get this

NoMethodError in Login#index

Showing app/views/login/index.rhtml where line #9 raised:

You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occured while evaluating nil.each

Extracted source (around line #9):

6:

\<%= column.human\_name %\>  
7: \<% end %\>  
8:   
9: \<% for account in @accounts %\>  
10:   
11: \<% for column in Account.content\_columns %\>  
12: \<%=h account.send(column.name) %\>

RAILS\_ROOT: ./script/…/config/…  
Application Trace | Framework Trace | Full Trace

#{RAILS\_ROOT}/app/views/login/index.rhtml:9:in `_run_rhtml_login_index' -e:4:in`load’  
-e:4

Any suggestions would be appreciated.

Either there are no @accounts being returned or haven’t setup the  
@accounts instance variable in your controller.

Try putting a condition before the loop that checks to see if there are  
any accounts in @accounts like:

\<%if @accounts.nil?%\>  
no accounts or account instance var  
\<%else%\>  
I have this many accounts: \<%=@accounts.length%\>  
#your stuff here  
\<%end%\>
