如何访问 Django 表单中的复选框数据

Question

我的 Django 表单中有几个复选框。在用户 select 选择了一个特定的复选框后，我想知道用户 select 编辑了哪些所有复选框。我可以在 Django 管理员中看到用户在填写表单时提供的名字、姓氏、用户名和电子邮件，但我看不到用户选择了哪些复选框 select。

如何访问复选框的数据？我知道我需要为此对我的代码进行一些修改，所以请建议我对我的代码进行修改。我正在使用 Django 1。9.I 浏览了一些在线资料和文档，但不太了解。

forms.py

from django import forms
from django.contrib.auth.models import User
from volunteer.models import UserProfileInfo

NGO_CHOICES = (
('one', 'ONE'),
('two', 'TWO'),
('three', 'THREE'),)

class UserForm(forms.ModelForm):
ngo = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, 
choices=NGO_CHOICES)

class Meta():
    model = User
    fields = ('ngo','email','first_name','last_name','username')

views.py

from django.shortcuts import render
from volunteer.forms import UserForm



def register(request):

registered = False

if request.method =="POST" :
    user_form = UserForm(data=request.POST)

    if user_form.is_valid():
        ngo = user_form.cleaned_data['ngo'] #getting the list of the ngos. 

        user = user_form.save()

        user.save()

        registered = True

    else:
        print(user_form.errors)

else:
    user_form = UserForm()

return render(request, 'volunteer/volunteer.html',
                         {'user_form':user_form,
                          'registered':registered})

models.py

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

class UserProfileInfo(models.Model):

    user=models.OneToOneField(User)

    def __str__(self):
            return self.user.first_name
            return self.user.last_name
            return self.user.email
            return self.user.ngo

admin.py

from django.contrib import admin
from volunteer.models import UserProfileInfo

# Register your models here.
admin.site.register(UserProfileInfo)

urls.py

from django.conf.urls import url

from . import views

app_name = 'volunteer'

urlpatterns = [

 url(r'^', views.register, name='register'),
 ]

volunteer.html（形式为）

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">


<meta name="viewport" content = "width=device-width, initial-scale=1.0">




</head>      

<body>   

 <div class="jumbotron">
    {% if registered %}
       <p>Thank you.<p>

    {% else %}
      <h1>Register yourself for Volunteering</h1>




 <form method="post">
    {% csrf_token %}
    {{ user_form.as_p }}
 <input type="submit" name="" value="Register as a Volunteer">

 {% endif %}

 </div> 


 </form>

</body>
</html>

注意 - 由于格式问题，我没有在上面的 HTML 代码中包含 bootstrap、ajax 和 jquery 库，我不认为它们有什么关系的问题，所以。

您可以在视图中访问表单中的所有数据。只需打印 request.POST 即可查看选中了哪个复选框。
