[Renand]

Hi Chris, I made this change an test it in CF9 only.

[chrisdpeters]

Thank you very much for submitting this code. I am reviewing it right now and will get back to you as soon as I can.

There are some issues in this pull request that keep me from being able to pull it in.

Basically, I cannot accept this with these commits:

• cd0ea55 - Add a :controller placeholder to hasAttachment() method
• dffbc00 - Add a imageTagUrl attribute to store a path without /images at start.

Can you correct and send me a pull request with the other 3 commits?

• 53cd026 - Fixe issue validatesAttachmentPresenceOf should call this.addError on error #4
• 91b6d35 - Add the renaming attribute to hasAttachment() method
• 0184c05 - Only try to save file if form is not empty

Hi Chris, sorry, but I I do not understand exactly, because my english is not perfect :)

For the controller attributes, is based on pluralize the model name, do you think is a mistake ?
do I have to understand that you need only one commit for all ?

Sorry, but i'm new as developer and with git... :(

Because you call hasAttachment() in a model, you should not have a :controller option. The model is not supposed to know anything about the controller.

If you'd rather the model be pluralized, then pass the url and path arguments each time you call hasAttachment() with the pluralized model name included.

<cfset hasAttachment(property="avatar", path="/files/attachments/users/:property/:id/:style/:filename", url="/files/attachments/users/:property/:id/:style/:filename")>

I'm tempted to add an argument named pluralizeModelName, but I'd rather keep it simple.

Can you just send pull requests with each feature committed separately? You're trying to solve Issue 4 and add a bunch of other stuff in one go, and I'd like to comment on each addition separately (as I've already done in your separate commits).

By the way, thank you for all of your help! I appreciate it!
