Laravel Backpack not uploading image - laravel-5

Question

I am attempting to upload a file (country flag) to a simple table countries which should be saved in a "flags" folder of public.
In my add field declaration I have
$this->crud->addField([ // image
'label' => "flag",
'name' => "flag",
'type' => 'image',
'upload' => true,
'disk' => 'flags', // in case you need to show images from a different disk
'prefix' => 'flags/'
and in the filesystems file I have:
'flags' => [
'driver' => 'local',
'root' => public_path('flags'),
'url' => '/flags',
'visibility' => 'public',
],
When I upload it tells me that the field is too short (it is varchar 255) as it seems to want to store the file as data image.

You should take another look at all the instructions for the image field type, in the documentation. Backpack does not take care of the uploading for you - you need an accessor on your Model, so you can choose where it's uploaded and how. If you don't do that, Backpack will try to store it as Base64 in your database - which isn't a good idea in most cases.
Example accessor for flag:
public function setFlagAttribute($value)
{
$attribute_name = "flag";
$disk = "public_folder";
$destination_path = "uploads/folder_1/subfolder_3";
// if the image was erased
if ($value==null) {
// delete the image from disk
\Storage::disk($disk)->delete($this->{$attribute_name});
// set null in the database column
$this->attributes[$attribute_name] = null;
}
// if a base64 was sent, store it in the db
if (starts_with($value, 'data:image'))
{
// 0. Make the image
$image = \Image::make($value)->encode('jpg', 90);
// 1. Generate a filename.
$filename = md5($value.time()).'.jpg';
// 2. Store the image on disk.
\Storage::disk($disk)->put($destination_path.'/'.$filename, $image->stream());
// 3. Save the path to the database
$this->attributes[$attribute_name] = $destination_path.'/'.$filename;
}
}
