django redux形式的復選框。 我正在使用django-redux

Question

我在Django redux注冊表格中添加了兩個復選框。 現在，我可以選中這兩個選項，但是我希望用戶一次選擇任何一個。 如何實現呢？ 下面是我的代碼

models.py

from django.db import models
from django.contrib.auth.models import User

# Create your models here.
class UserSelection(models.Model):
    employer = models.BooleanField()
    candidate = models.BooleanField()
    user = models.OneToOneField(User)

表格

from django import forms
from registration.forms import RegistrationFormUniqueEmail

class MyRegForm(RegistrationFormUniqueEmail):
    employer = forms.BooleanField()
    candidate = forms.BooleanField()

regbackend.py

from registration.backends.default.views import RegistrationView
from .forms import MyRegForm
from .models import UserSelection

class MyRegistrationView(RegistrationView):
    form_class = MyRegForm

    def register(self, form_class):
        new_user = super(MyRegistrationView, self).register(form_class)
        p = form_class.cleaned_data['employer']
        q = form_class.cleaned_data['candidate']
        new_profile = UserSelection.objects.create(user=new_user, employer=p, candidate=q)
        new_profile.save()
        return new_user

Answer 1

您確定要兩個布爾字段嗎？ 如果您有一個帶有選擇項的char字段，則該表格僅允許您選擇一個選擇項。

USER_TYPE_CHOICES = [
    ('employer', 'Employer'),
    ('candidate', 'Candidate'),
]

class UserSelection(models.Model):
    user = models.OneToOneField(User)
    user_type = models.CharField(max_length=10, choices=USER_TYPE_CHOICES)

如果您確實需要兩個布爾字段，則可以為模型編寫一個干凈的方法。

from django.core.exceptions import ValidationError

class UserSelection(models.Model):
    employer = models.BooleanField(blank=True)
    candidate = models.BooleanField(blank=True)
    user = models.OneToOneField(User)

    def clean(self):
        if self.employer and self.candidate:
            raise ValidationError("You cannot select employer and candidate")
        if not (self.employer or self.candidate):
            raise ValidationError("You must select employer or candidate")

請注意，您需要在布爾字段上輸入blank=True ，以允許用戶取消選中它們。
