Incompatibility problem with wtforms 3.0.0a1

FileUploadField seems to be incompatible with wtforms >= 3.0.0a1 The problem is: TypeError: process() got an unexpected keyword argument 'extra_filters' The process function overridden in the FileUploadFile class does not specify ‘extra_filters’ as a keyword argument.

wtforms==2.3.3 works, at least for this issue.

Looks like the fix has been merged in Oct 2021, but the last release is from Apr 2021. Any chance we can get another release?

form_extra_fields = { “file_upload”: self.form.FileUploadField() }

при добавлении в class StorageAdminModel(ModelView):

возникает эта ошибка. Как добавить поле file_upload в админку?

Model:

class StorageModel(db.Model): tablename = ‘storage’

id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.Unicode(64))
path = db.Column(db.Unicode(128))
type = db.Column(db.Unicode(3))
create_date = db.Column(db.DateTime, default=datetime.now)

class StorageAdminModel(ModelView): form_extra_fields = { “file_upload”: form.FileUploadField() }

# form_columns = ('create_date', 'path', 'type', 'file_upload')
def _list_thumbnail(self, context, model, name, form_extra_fields):

    column_formatters = {
        'path': self.list_thumbnail
    }
    if not model.path:
        return ''

    url = url_for('static', filename=os.path.join('storage/', model.path))

    if model.type in ['jpg', 'jpeg', 'png', 'svg', 'gif']:
        return Markup('' % url)

    if model.type in ['mp3']:
        return Markup('' % url)
