Django CheckboxSelectMultiple 不显示在 ModelForm 中

Django CheckboxSelectMultiple not displaying in ModelForm

我正在尝试在表单中使用 CheckboxSelectMultiple,而不是默认的 SelectMultiple。我尝试了两种不同的方法让它显示为复选框,但它们都在我的本地网页上显示默认的 SelectMultiple。其他一切都正确呈现({{ form.as_table }})。有人会指出我正确的方向吗?谢谢,

Django 版本 3.0.2

Python 3.6.9

models.py

class MyModel(models.Model):
    m2m = models.ManyToManyField('OtherModel', blank=True)

    [...]

forms.py

from django.forms import ModelForm
from myapp.models import MyModel

class MyModelModelForm(ModelForm):
    [...]
    # I tried this...
    m2m = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple)

    class Meta:
        model = MyModel
        fields = '__all__'
    
        # or this...
        widgets = {
            'm2m': forms.CheckboxSelectMultiple,
        }

views.py

from django.views.generic.edit import CreateView
from myapp.models import MyModel

class MyModelCreate(CreateView):
    model = MyModel
    fields = '__all__'
    template_name = 'MyApp/mymodel_form.html'

您没有使用您构建的表格。您只是构造一个 ModelForm,然后让 CreateView 创建另一个 ModelForm,因为您没有指定 form_class [Django-doc]

因此您可以更新 CreateView,并使用:

from django.views.generic.edit import CreateView
from myapp.models import MyModel
from myapp.forms import <b>MyModelModelForm</b>

class MyModelCreate(CreateView):
    model = MyModel
    <b>form_class = MyModelModelForm</b>
    template_name = 'MyApp/mymodel_form.html'
