How to replace the entity photo?

Question

symfony

When I add a company, I need to upload its logo:
I upload it like this:
AddCompanyType:

$builder->add('image', new FileType(), array('label' => 'Логотип'));

filetype:

$builder->add('file', 'file', array('label' => false));

The download is working fine. But I can't figure out how to edit a picture when I edit a company.
We need the same form, with a clean logo upload field. When saving - if the logo field is empty, then the logo is not updated; if a new logo is given, then update it.

Well, in the controller, you can describe the logic for updating the entity, and not just automatically fill it with new data from the form.
