Thanx for jumping in Degee -
Hi Tony,
The problem is you're using the user's form and including attributes
of another model in it. I guess your params look like 'user' =>
{ 'name' => 'something', ..., 'filename' => 'image.jpg'}, but filename
is not an attribute of User model but of Image model.
Jodi's tip of creating a separate model has more implications than
just setting up the relationship: You should create a separate
controller for creating the image: In your user's form, surely when he
wants to add an image, he gets to an image upload view. This would
call a create action in the ImageController:
def create # in ImageController, not UserController
@user = current_user # or User.find(params[:user_id]) if you post
the user_id in the form for the image.
@image = Image.new(params[:image]) #this is where the filename
attribute gets set
if @image.save
@user.image << @image #associate image to the user
...
else
...
end
end
If you prefer to do the association only when the user saves his
profile, you could just pass the image_id back to the form for the
user's profile and then add the association with the UserController
update action. As image_id is an attribute of user, you can just mass-
assign it like you show in @user.update_attributes(params[:user]).

installed everything and setup a test scaffold following the
uploading the image at the time of registration. I've been trying to
just editing a user. I'm sure I'm just overlooking something, any help
is appreciated!!
Let me know if there is something else you need to know. Thank you for
your time!
best to place your images in a separate model.
has_many :images
but best if images has a polymorphic relationship - that way you can
add images to other models
Class User < ActiveRecord::Base
has_many :images, :as => :attacheable, :dependent => :destroy
end
Class Image < ActiveRecord::Base
belongs_to :attacheable, :polymorphic => true
has_attachment :storage => :file_system, ...
end

Hi Jodi,
Thanks for the reply. I tried adding the additional table relationships
as you suggested but I'm getting an error on the user update action:
undefined local variable or method `filename' for #<User:0x2564508>
I have the standard update code in my controller:
def update
@user = User.find(params[:id])
respond_to do |format|
if @user.update_attributes(params[:user])
flash[:notice] = 'User was successfully updated.'
format.html { redirect_to(@user) }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @user.errors, :status =>
:unprocessable_entity }
end
end
end
and the view code for the upload is:
<%= file_field_tag :uploaded_data %>
Any help is appreciated! Thanks.

I prefer to create images within the (in this case) the UserController.
ripped out of a project
View - <multipart form tag here>
<%= file_field_tag "photo", :id => "photo_image", :class => "attach_photo" %>
<%= text_field_tag "caption", nil, {:id => "photo_title", :class => "attach_photo"} %>
User controller - after @user object is valid + saved
#attached uploaded pics - an array of photos + captions
if params[:photo]
params[:photo].each_with_index do |image, caption_index|
caption = ''
caption = params[:caption][caption_index] if params[:caption] && params[:caption][caption_index]
@user.images.create!(:uploaded_data => image, :caption => caption) if image.size != 0
end
end
