Hi Everyone!
I'm trying to add the avatar upload functionality in Ruby on rails
following the railsspace book.
Before I got the code and re-wrote it for my own needs, I wanted to
make sure everything worked anyway, so I added the code from the book
to the avatar controller etc..
When I attempted an upload, I got an error: NoMethodError in
AvatarController#upload
So, when I look at the upload function, all seems OK to me. I'm
running rails 2.3.3 and have managed to get past every issue so far
without reverting back to an earlier version.
def upload
@title = "Upload Your Avatar"
@user = User.find(session[:user_id])
if param_posted?(:avatar)
image = params[:avatar][:image]
@avatar = Avatar.new(@user, image)
if @avatar.save
flash[:notice] = "Your avatar has been uploaded."
redirect_to hub_url
end
end
end
Originally it had a problem because of this:
def index
# redirect_to hub_url
end
The error with this code in place reads: undefined local variable or
method `hub_url. This is displayed upon accessing url :
http://localhost:3000/avatar
Can anyone help?
I might look for another tutorial to upload avatars, but was hoping
there would be a simple solution..
Cheers!
