Perhaps it would be useful if you told us which is line 66.

In case I have made a lucky guess and it is this line then look in
development.log to see what params[:user] will be. Also have a look
at the Rails Guide on debugging to see techniques that can be used to
debug your code.

I gues it's raise because you don't assign object. You should change it this way:

<%= select("user", "team_id", Team.all.collect { |p| [p.name, 

p.id] }, {:include_blank => 'None'}) %>

Hi
Thanks for the help, i managed to get this to work with the following
line

<%= f.select("team_id", Team.all.collect { |p| [p.name, p.id] }, {

:include_blank => 'None' }) %>

though in my view/users/index
when i call the following <%= user.team %> i am getting this displayed
#<Team:0x10532a4f0>, i want it to display what team the player has been
allocated to

in my view/teams/show if i call the following
<% for player in @team.users %><%= player.first_name %> <%=
player.last_name %>
i can see what players are loaded for a particular team

thanks

That (#<Team:0x10532a4f0>) *is* the team - a Team *object*.

Maybe you actually want to display an *attribute* of the object? Like
says its name? Look at your own 'player' example.

hi hassan
i have tried something similar and got this

NoMethodError in Users#index

Showing
/Users/*****/Sites/rails_projects/*****/app/views/users/index.html.erb
where line #67 raised:

undefined method `teams' for nil:NilClass
Extracted source (around line #67):

64: <td
65: <% if session[:user_id] == user.id %>

67: <% for team in @user.teams
68: team.name
69: end %>

? That's not remotely similar to your original example:

> when i call the following <%= user.team %> i am getting this displayed

Doesn't it seem apparent that if this <%= user.team %> shows you the
team object, <%= user.team.name %> would show you the e.g. name
attribute of that object?

Thanks Hassan, I now have a better understanding of what you mean
