Hi Andy,
Ok, i missed all that from my quick scan of the code. Sounds
excellent. What i'll do first is use your version as a base and then
fix some of the things i found like the resizing and not being able
to update 'extra' fields you might have used without uploading a new
image.
I guess the second step would indeed be to generalize everything a
bit more for file uploads of different types. I could take a look at
the cheesecake method for 'outsourcing' image handling to a vendor.
Some way to configure actions based on mimetype arrays would be
nice... The filename array could serve as a base for that, i do like
that you can set that up in the single model and don't need much
logic in the controller at all. Something like this might work:
var $actsAs = array('Upload' => array(
'filename' => array(
'Image'=> array( // <-- file subtypes (may or
may not refer to
model)
'dir' => 'files/images',
'overwrite_existing' => false,
'create_directory' => false,
'allowed_mime' => array('image/jpeg',
'image/pjpeg', 'image/
gif', 'image/png'),
'allowed_ext' => array('.jpg', '.jpeg',
'.png', '.gif'),
'thumbsizes' => array(
'small'
=> array('width'=>100, 'height'=>100),
'medium'=> array('width'=>220, 'height'=>220),
'large'
=> array('width'=>800, 'height'=>600)
)
)
'Document'=> array(
'dir' => 'files/docs',
'overwrite_existing' => false,
'create_directory' => false,
'allowed_mime' => array('text/plain',
'application/msword',
'application/pdf'),
'allowed_ext' => array('.txt', '.pdf',
'.doc'),
'parse_text' => array(true,
'db_field'=>'text'), // parse text
and store in db field for searches/extract
)
)
)
)
);
If you keep the handlers reasonably generic you could switch out
vendors for each task with relative ease. This could get out of hand
easily too though ;) You think each fieldtype should be handled by
it's own model or should they just be methods of the File/Upload model?
