The UploadableBehavior helps you handle uploaded files with Propel.

Installation

Add it-blaster/uploadable-behavior to your composer.json file and run composer

...
"require": {
    "it-blaster/uploadable-behavior": "1.0.*"
}
...

...
propel:
    behaviors:
        uploadable: Fenrizbes\UploadableBehavior\Behavior\UploadableBehavior
...

Add the behavior to your table:

...
    <behavior name="uploadable" />
</table>
...

By default it finds or creates a varchar column named file, but you can configure your own columns:

...
    <behavior name="uploadable">
        <parameter name="columns" value="image, document" />
    </behavior>
</table>
...

The behavior adds a few methods to the base class that help it, and you can override and extend any of them.

getUploadRoot returns an absolute path to the web directory of your project. By default it returns the most common path, but the best way is setting this path to a model in your controller.
getUploadDir returns a relative path from the root dir to the file's folder. By default it's /uploads/<model_name>/<year>/<month>/<day>.
makeFileName generates the name for the file randomly.
moveUploadedFile moves the file and sets new value to its column. If you're overriding this method, remember that it has to return a web path to the uploaded file (of course if you don't want to change its behavior).

Remember that this behavior handles uploaded files (moves them and sets columns' values) and does nothing more. So:

if you don't have a view transformer or overridden getters that convert string file paths to File objects, set null to the data_class option of form fields;
if you send an empty value for file field and don't want to erase column's value, handle it yourself;
if you want to have a way to delete uploaded files, do it yourself;
if you need anything else... well, you know.
