Rails: undefined method '(MODELNAME)'? - ruby-on-rails

Question

Hi I'm currently making a web app for uploading pics. There are users, albums, and photos. I'm having trouble trying to figure out what's going on when I try to edit a user's profile information. It is telling me that there is an undefined method 'album' NoMethodError in UsersController#update , but I don't even call album in my #update action.
def update
respond_to do |format|
if current_user.update_attributes(params[:user])
format.html { redirect_to current_user, notice: 'User successfully updated.'}
format.json { render json: current_user, status: :created, location: current_user }
else
format.html { render action: 'edit' }
format.json { render json: current_user.errors, status: :unprocessable_entity }
end
end
end
the error is specifically on the 2nd and 3rd lines of my update action. Here's the error:
app/controllers/users_controller.rb:45:in 'block in update'
app/controllers/users_controller.rb:44:inupdate'`
anyone know what the heck is going on?
edit form for users
<%= form_for(#user) do |f| %>
<div class="formhold">
<div class="field">
<% if #user.profilepic? %>
<%= image_tag #user.profilepic.url %>
<% end %>
<%= f.label :profilepic, "Profile Picture" %>
<%= f.file_field :profilepic %>
</div>
<div class="field">
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :email %>
<%= f.text_field :email %>
</div>
<div>
<%= f.submit 'Submit', :class => 'submitbutton' %>
</div>
<% if #user.errors.any? %>
<div id="error_exp">

<ul>
<% #user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
</div>
<% end %>

Try commenting out:
validates :album, :uniqueness => true
It is assuming that :album is an attribute/method of user and failing. You should handle your unique validations for albums in albums model, depending on your business logic. You can validate them based on user_id or some other attribute with :scope => [:user_id]
