I’d like to prompt a user for the value of a Name field, then display
the record. Rails tells me that it cannot do a find without an ID. I
guess it must be that I’m not passing back properly the data from the
view to the controller.
Thanks for the help

The find_user.rhtml view:
Enter User Name
<%= start_form_tag %>
Name:
<%= text_field_tag :name, params[:name] %>
<%= submit_tag "Find", :class => "submit" %>
<%= end_form_tag %>
The find_user action in user_controller.rb
def find_user
user = User.find_by_name(params[:name])
if user
redirect_to(:controller => “user”, :action => “show”)
else
flash[:notice] = “Unable to find user name”
end
end
