Question

我尝试在我的表单中创建单选按钮和复选框，并尝试分别使用模型字段ChoiceField和MultipleChoiceField。

forms.py

from django import forms
from rango.models import Evangelized

class EvangelizedForm(forms.ModelForm):
    gender = forms.ChoiceField(widget=forms.RadioSelect(
                 choices=Evangelized.GENDER_CHOICES), help_text="Gender")
    area_of_interest = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(
                                                    choices=Evangelized.AREA_CHOICES), help_text="Areas of interest(Upto 3)")

models.py

from django.db import models

class Evangelized(models.Model):
    GENDER_CHOICES = (('M', 'Male'), ('F', 'Female'), ('U', 'Unisex/Parody'))
    gender = models.ChoiceField(choices=GENDER_CHOICES)
    AREA_CHOICES = (('Govt', 'Govt'), ('Entertainment', 'Entertainment'), ('Automobile', 'Automobile'),
                        ('Careers', 'Careers'), ('Books', 'Books'), ('Family', 'Family'), ('Food', 'Food'),
                            ('Gaming', 'Gaming'), ('Beauty', 'Beauty'), ('Sports', 'Sports'), ('Events', 'Events'),
                                ('Business', 'Business'), ('Travel', 'Travel'), ('Health', 'Health'), ('Technology','Technology'))
    area_of_interest = models.MultipleChoiceField(choices=AREA_CHOICES)

但是，在分别处理每种类型的模型字段时，我遇到以下错误：

 'module' object has no attribute 'ChoiceField'



'module' object has no attribute 'MultipleChoiceField'

我的代码似乎有什么问题？

Answer 1

模型定义数据库级别类型。

您必须指定模型的数据类型，并且可以使用“choices”kwarg指定选项。

所以，你的模型应该是这样的：

from django.db import models

class Evangelized(models.Model):
    GENDER_CHOICES = (('M', 'Male'), ('F', 'Female'), ('U', 'Unisex/Parody'))
    gender = models.CharField(max_length=1, choices=GENDER_CHOICES)

对于多选字段，您可以使用CommaSeparatedIntegerField。

我建议您查看docs有选择的模型

Answer 2

您应该使用 models.CharField :-) see documentation

gender = models.CharField(max_length=1, choices=GENDER_CHOICES)

Django：＆＃39;模块＆＃39;对象没有属性＆＃39; ChoiceField＆＃39;，＆＃39; MultipleChoiceField＆＃39;
