Rails - Dec 2007 - how do i update an image with Attachment_Fu ?

Hi, making the switchover from the file_upload plugin to the pretty
awesome Attachment_Fu plugin to handle all my image uploads,

so far going good, but stuck on two things?

Any ideas how i can basically update an image & delete an image ?

can''t seem to find any good examples anywhere,

appreciate it,



John.

it should support User.update_attributes(params[:user])

where user.rb has the has_attachment in the model and inside params[:user]
is an "uploaded_data" file field.

Thanks for that,

here''s my working [delete] button on the show page

<%= button_to "Delete Photo", :action => "destroy",
:id => @image %>

and my destroy method...

  def destroy
    Image.find(params[:id]).destroy
    redirect_to :action => ''list''
  end


and here''s the [edit] page...

<% form_for(:image, :url => {:id => @image, :action =>
"update" }, :html
=> { :multipart => true }) do |f| -%>

<p>Replace Photo:<br/>
<%= image_tag @image.public_filename(:thumb) %>
<br/>
with <%= f.file_field :uploaded_data %>
</p>

<p>
<%= f.submit ''Save Changes'' %>
 or
<%= button_to_function "Go Back", 
"window.location=''/image/show/#{@image.id}''" %>
</p>

<% end -%>

and the method...

  def edit
    @image = Image.find(params[:id])
  end

  def update
    @image = Image.find(params[:id])
    if @image.update_attributes(params[:image])
      flash[:notice] = ''Photo was successfully updated.''
      redirect_to :action => ''show'', :id => @image
    else
      flash[:notice] = ''Something awful just happend!''
      render :action => ''edit''
    end
  end


all work, just thought i should post them, so glad i got that out of the 
way, thanks AD
