Hey guys,

I’m having a hard time with some weird behavior in my application.  
Every time I logout a particular has\_many relationship seems broken.  
When I first login, my relationship user.profile.comments works as  
expected, but when I logout and login with another user, I get:

NoMethodError in ProfileController#show  
undefined method `comments’ for #Profile:0x46ff26c

My Models:  
class User \< ActiveRecord::Base  
has\_one :profile  
end

class Profile \< ActiveRecord::Base  
has\_many :comments  
belongs\_to :user  
end

class Comment \< ActiveRecord::Base  
belongs\_to :profile  
end

And here is my login and logout procedure in my controller:

class UserController \< ApplicationController  
def login  
if request.post?  
if session[:user] = User.authenticate(params[:user][:login],  
params[:user][:password])  
flash[:message] = “Login Successful”  
redirect\_to\_stored  
else  
flash[:warn] = “Login Error”  
end  
end  
end

def logout  
session[:user] = nil  
flash[:message] = ‘Logged out’  
redirect\_to :action =\> ‘login’  
end  
end

Any ideas?

Thanks,  
Javier G.

Have you tried restarting your server? By the looks of things, it’s not  
getting that has\_many definition in Profile.

Ryan,

Well, if I restart the server it works until I logout and login with  
the same or another user.  
I was wondering if anyone has seen behavior like this before.  
I can code around this with something like  
Comment.find\_all\_by\_profile\_id(@user.profile.id) but I want rails to  
make this relationship transparent.

Thanks,  
Javier

How are you calling comments at the moment?

OK, I think I figured it out, it seems to me that requiring a model  
(ActiveRecord::Base) in a controller throws many things off in rails.  
Has anyone experienced this before? Things such as what I describe  
below don’t seem to work right. What I was doing is something like:  
require ‘user’ at the top of some controller.

Thanks for your help…  
Javier G.

I am calling it like this:  
@profile.comments where @profile = @user.profile  
here is the subroutine:

def show  
if params[:id]  
@user = User.find\_by\_login(params[:id])  
else  
@user = User.find(current\_user.id)  
end

```
@profile = @user.profile
@photos = Photo.find_all_by_profile_id(@user.profile.id,

```

:conditions =\> [“removed = 0”])  
@photo = Photo.find\_by\_profile\_id(@user.profile.id, :conditions =\>  
[“removed = 0 AND main = 1”])  
if @photo.nil?  
@photo = Photo.find(1)  
end

```
@spot_pages, @spots = paginate_collection(
  @user.spots.find(:all, :order => 'created_at DESC'),
  :page => params[:page])

@buddies = User.find_by_sql(
  ["SELECT u.* FROM buddies_users b, buddies_users c, users u " +
    "WHERE b.buddy_id = ? " +
      "AND u.id = b.user_id " +
      "AND b.user_id = c.buddy_id " +
      "AND b.buddy_id = c.user_id", @user])

@comment_pages, @comments =

```

paginate\_collection(@profile.comments.find(:all,  
:order =\> ‘created\_at DESC’), :page =\> params[:page])  
end

Well, I’ve been working on this for a while, learning as I go and I  
believe that was something I did erroneously.

Thanks.

Why are you requring a model in a controller? All models are included  
automatically.
