Re: Media PLugin

Gosh my reply sounded harsh on you Jeremy - that wasn't my intention. We've commented out the line that unsets the data and it *all seems fine*, which also feels dirty. The user records are saving correctly, we can subsequently add images to user records and all other dedicated image tables that use the coupler are functioning too. I did reach out to David yesterday, hoping to learn more from him so that we can implement this properly and will report back.

I didn't say I agreed with how it worked, I was just explaining what I think the author's intended use case was. The question was if you were missing a setting or doing anything wrong. You weren't, so I just threw out some ideas based on how the Coupler works. Feel free to take it up with the author or create a Coupler that works for you.

I'm glad that an empty image doesn't create garbage data, that thought was based off of what the Coupler does down the road (check the file and populate dirname and basename).

I understand what you are saying but I don't think it's the full answer. It's a perfectly valid use case to have a table that has an optional image in it without the need to have a separate join table. The absence of the image doesn't create any garbage data; the user row is still valid. A bio snap for a user is good example. For the plugin to simply clear the whole data array because the optional image fields aren't populated is nuts. If the fields are empty simply return true and let the main model get on with its work.

It should only unset the data if you are creating the User and it's missing the 'file' key. If you are updating, you shouldn't *need* the 'file' key.

That said, you can probably get away with passing an empty (or a path to a default image) file key when you are creating the User using a hidden field. This should allow the coupler to continue with the save. This may save some empty garbage data that is probably unwanted.

The other solution would be to detach the Coupler behavior at runtime when you don't want it to "force" you to have an image.

The whole point of the Coupler is to tightly couple the physical image to the record, so if the image doesn't exist neither should the record. I tend to create a separate table for attachments for this very reason. A user should be allowed to exist without an image.

when the user does not have an image because of the beforeSave in
coupler.php:

        function beforeSave(&$Model) {
                if (!$Model->exists()) {
                        if (!isset($Model->data[$Model->alias]['file'])) {
                                 unset($Model->data[$Model->alias]);  <<<--- clears down my User
data
                                return true;
                        }
                } else {

This is unsetting the User data because the file key is missing. If I
comment out the unset my User->save is successful. The Media.Coupler
is working perfectly well for another table that hasMany images in an
associated table.

Is there a setting I need to configure or am I doing something else
wrong?
