Question

我发现这比我想象的要复杂得多。我有Django 1.4.5并且使用模型原型和模板想要创建具有多个复选框的选项。我很想使用模型，表单和视图方法，因为我以后会使用数据库。现在，我只是无法找到如何显示多个可以允许多个选择的复选框。

Models.py

GENDER_CHOICES = (
    ('M', 'Male'),
    ('F', 'Female'),
    ('O', 'Other'),
)

class Gender(models.Model):
    MALE = 1
    FEMALE = 2
    OTHER = 3
    gender = models.CharField(('Gender'), max_length=512, choices=GENDER_CHOICES,blank=True)

class MyPreferences(models.Model):
    MyGenderPref = models.ManyToManyField(Gender, blank=True, null=True)

Forms.py

class MyPreferencesForm(forms.Form):
        MyGenderPref = forms.MultipleChoiceField(choices=GENDER_CHOICES,widget=forms.CheckboxSelectMultiple())

Views.py

from django.forms import ModelForm
from django.forms import forms
from TestForm.models import MyPreferences


def GoPreferences(request):
    if request.method == "POST":
        form = MyPreferencesForm(request.POST)
        if form.is_valid():

            commit=False means the form doesn't save at this time.
            commit defaults to True which means it normally saves.
            model_instance = form.save(commit=False)
            model_instance.timestamp = timezone.now()
            model_instance.save()
            return redirect('victory')
    else:
        form = MyPreferencesForm()

    return render(request, "aboutme.html", {'form': form})

然而，当我尝试这个时，我得到：

GET
Request URL:    http://127.0.0.1:8080/myprefs
Django Version: 1.4.5
Exception Type: NameError
Exception Value:    
name 'MultipleChoiceField' is not defined
Exception Location: /home/brett/TestForm/TestForm/forms.py in MyPreferencesForm, line 17
Python Executable:  /usr/bin/python
Python Version: 2.7.4

这样做的最佳方法是什么，以便我以后可以轻松使用数据库。但与此同时，我无法实现这一目标。

在导入部分，您有

from django.forms import forms

也许应该是

from django import forms
