I realize the title probably doesn''t make much sense, but that was the
best short description I could come up with.
Anyway, I have users and pages in my site, and was using the following
code in the users controller, which works fine:
<code>
def show
@user = User.find(params[:id])
@title = @user.Fname + " " + @user.Lname
en
</code>
However, if I go to the pages controller, and use the following code, I
get "Couldn''t find user without an id" for an error.
<code>
def home
@title = "Home"
@user = User.find(params[:id])
end
</code>
Using User.find(1) works just fine instead of User.find(params[:id])
I feel like I''m probably just restricting something to Users only
somehow, but can''t figure it out. Seems like it would be obvious to
someone more experienced, (I hope?)

On the other hand it sounds like when you link to your home action in the pages controller you''re not supplying an id parameter, and so params[:id] is nil, so User.find(params[:id]) can''t work. Which user did you want to show? Fred> > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I wanted to pass it the id of the logged in user. I have some things that I want to show up for some users and not for others. I wanted to use @user.admin? for this, which works fine on the users pages. however, since I can''t get the @user assignment to work for pages this isn''t working either :( -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Aha! I''ve figured it out. In case anyone else is wondering, I have a current_user defined in sessions helper, so, I had to include sessionshelper, and set @user = current_user! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
