Here is a solution that expands upon Remo's answer and this so answer. It allows for different field_args for edit and create forms.

Custom Field Rule Class

from flask_admin.form.rules import Field

class CustomizableField(Field):
    def __init__(self, field_name, render_field='lib.render_field', field_args={}):
        super(CustomizableField, self).__init__(field_name, render_field)
        self.extra_field_args = field_args

    def __call__(self, form, form_opts=None, field_args={}):
        field_args.update(self.extra_field_args)
        return super(CustomizableField, self).__call__(form, form_opts, field_args)

UserView Class

class UserView(ModelView):

    column_list = ('first_name', 'last_name', 'username', 'email')
    searchable_columns = ('username', 'email')

    # this is to exclude the password field from list_view:
    excluded_list_columns = ['password']
    can_create = True
    can_delete = False

    # If you want to make them not editable in form view: use this piece:
    form_edit_rules = [
        CustomizableField('name', field_args={
            'readonly': True
        }),
        # ... place other rules here
    ]
