access controller''s object attributes in view page

Hi,

I am new to ROR and learning it. In my controller I have an admins
record and I am passing that admin object to the admin''s view page to
get the name of the admin. But when I try to access the name it is
showing error as  "undefined method `name'' for
:current_admin:Symbol"..
Please help..
Please find my code below

Sessions Controller

def create
  admin=Admin.find_by_email(params[:session][:email].downcase)
    if admin && admin.authenticate(params[:session][:password])
       redirect_to(admins_index_path(:current_admin=>admin))
     end
end

In view page of index_admin

<%="Hi"%><%=params[:current_admin.name]%>

 In the controller, assign the resultant admin record to the instance
variable as below:

*@admin=Admin.find_by_email(params[:session][:email].downcase)*

In your view page, use as below:

*<%="Hi"%><%= @admin.name%> *
*
*

I tried with the the below code. But still getting the same result in 
view page as "undefined method `name'' for nil:NilClass"

 def create
   @admin=Admin.find_by_email(params[:session][:email].downcase)
       user=User.find_by_email(params[:session][:email].downcase)
     if user && user.authenticate(params[:session][:password])
      redirect_to(dashboard_path(:user=>user))
    else
      redirect_to(admins_index_path(:current_admin=>@admin))
    end
  end

? And for the backward compatibility, use the below logic in your view so
that you can get the clarity in what you are doing :)

<% if !@admin.blank? %>
<%="Hi"%><%= @admin.name%>
<%else%>
no records
<%end%>

Side note --
you probably want to pass that as (:current_admin_id=>admin.id)

You''re doing a redirect, which means the request will be sent to the
controller and method associated with "admins_index_path".

In *that* controller and method, you must set the variables you need,
e.g.   @admin = Admin.find(params[:current_admin_id]

Then your view can use attributes e.g. @admin.name
