Hi all,
I''m creating admin module. in that module i need to get the list of
users and also the projects created by the each user.
No doubt i''m getting the list of users. but i''m not getting
the list
of projects done by each user..
This is my code::
<% for user in @users %>
<%=link_to
user.login,:action=>"list",:controller=>"projects",:id=>user.id%>
<%end%>
In the controller
def list
@user = User.find_all
@user_pages, @users = paginate :user, :per_page => 20
end
This is the error when i click on the user::
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.[]
Could any please help??

Don''t quite understand this. Think we need more details. Is the controller action below in the Projects controller? What is the view for the list action in this controller (that is presumably where the prob is)? What is does the line that contains the nil.[] error on show?

Sorry,
I gave the wrong controller.The below is the correct one::
1 def list
2 userId=@session[''user''][''id'']
3 @project_pages, @projects= paginate :projects, :per_page => 5,
4 :conditions=>"user_id=#{userId}"
5 user=User.find(userId)
6 end
This is the list.rhtml in users views
<% for user in @users %>
<%=link_to
user.login,:action=>"list",:controller=>"projects",:id=>user.id%>
<%end%>
The error is showing in line:2

Try looking at how you''ve set the user in the session
