best way customize field_error in symfony 3 - symfony

Question

i have a entity with path field
/**
* #var string
* #Assert\NotBlank(message="Please, upload scontrino/fattura della stufa acquistata.")
* #Assert\File(mimeTypes={ "application/pdf","image/png" ,"image/jpg","image/jpeg" })
* #ORM\Column(name="path_file", type="string", length=255)
*/
private $path;
i have this field in a form
->add('path', FileType::class, array('data_class' => null))
;
and in the twig file
<div class="row">
<div class="input-field col s12 ">
{{ form_errors(form.path) }}
{{ form_widget(form.path) }}
</div>
</div>
when i press submit button and i put i not allowed file now my message is
Il mime type del file non è valido ("application/zip"). I tipi permessi sono "application/pdf", "image/png", "image/jpg", "image/jpeg".
I want to change that message but i don't understand the best way to do that.
If i must do it in entity file or in form file or in twig file

Answer 1

You have to add:
mimeTypesMessage = "with the text you want", in the #Assert\File
in your #Assert\File of your entity
/**
* #var string
* #Assert\NotBlank(message="Please, upload scontrino/fattura della stufa acquistata.")
* #Assert\File(mimeTypes={ "application/pdf","image/png" ,"image/jpg","image/jpeg" }, mimeTypesMessage = "with the text you want")
* #ORM\Column(name="path_file", type="string", length=255)
*/
