Re: Dealing with Image Uploads

One approach is to add foreign_key and model columns to your images
table so you can create associations between Image and other models
like this:

public $belongsTo = array(
'Publication' => array(
'className' => 'Publication',
'foreignKey' => 'foreign_key',
'conditions' => array(
'Image.model' => 'Publication'
),
'dependent' => true
),
'Author' => array(
'className' => 'Author',
'foreignKey' => 'foreign_key',
'conditions' => array(
'Image.model' => 'Author'
),
'dependent' => true
)
);

You can then store settings for the various models within the Image class:

public $settings = array(
'Publication' => array(
'directory' => 'img/publications',
'width' => 220,
'height' => 288,
'wp' => 220,
'hp' => 288,
'wl' => 220,
'hl' => 288
),
...
);

Then create an ImageComponent to handle the upload and resize,
accessing the required settings much the same way that a behavior
reads its own settings for a given model. That is,
$this->__Controller->{$model}->Image->settings[$model]['width'], or
something similar. Of course, you'll need to pass the desired model
somehow, either in the upload form or as a parameter passed from the
controller to the component.

For Thumbnails, create a separate table and associate them by
image_id. The class itself can also have a $settings array similar to
that in Image, so that you can have various sizes of thumb.
