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| -%\>

Replace Photo:  
\<%= image\_tag @image.public\_filename(:thumb) %\>  
with \<%= f.file\_field :uploaded\_data %\>

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

\<% 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
