脆皮表格-RadioSelect / RequiredField

Question

我想从radioselect中删除破折号/必填字段。我不知道他们来自哪里？？？据我了解，它与requiredField类有关。请帮助：）

forms.py

from django import forms
from voyelo.models import User
from crispy_forms.helper import FormHelper
from crispy_forms.bootstrap import InlineRadios

class NewUserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = "__all__"
        widgets = {
          'comments': forms.Textarea(attrs={'rows':8, 'cols':38}),
          'iletisim': forms.RadioSelect,
        }
        labels = {
        "first_name": "İsim",
        "last_name": "Soyisim",
        "customer_quantity": "Kişi Sayısı",
        "reservation_date": "Tarih",
        "phone": "Telefon",
        "email":"Email",
        "iletisim":"Size Nasıl Ulaşalım?",
        "comments":"Yorumlarınız",
        }

models.py

from django.db import models

# Create your models here.


class User(models.Model):

    ILETISIM = [
    ('email', 'Email'),
    ('arama', 'Arama'),
    ('whatsapp', 'Whatsapp'),
    ]

    first_name = models.CharField(max_length=128)
    last_name = models.CharField(max_length=128)
    customer_quantity = models.CharField(max_length=3, null=True)
    reservation_date = models.DateField(blank=True, null=True)
    phone = models.CharField(max_length = 20, null=True)
    email = models.EmailField(max_length=264, unique=True)
    iletisim = models.CharField(max_length=8, choices=ILETISIM)
    comments = models.CharField(max_length=600, null=True)
