Django 复选框字段

Question

我正在尝试添加一个复选框，如果勾选将使我的模型中的属性为 false。

我的模型是:

 class Topic(models.Model):
        """A topic the user is learning about"""
        text = models.CharField(max_length=200)
        date_added = models.DateTimeField(auto_now_add=True)
        owner = models.ForeignKey(User)
        public = False

My forms.py (where the checkbox should go) is:

class TopicForm(forms.ModelForm):
    class Meta:
        model = Topic
        fields = ['text']
        labels = {'text': ''}

我的功能:

def topics(request):
    """Show all topics."""
    topics = Topic.objects.filter(owner=request.user).order_by('date_added')
    context = {'topics': topics}
    return render(request, 'learning_logs/topics.html', context)

您能否告诉我我需要更改什么，以便在选中表单中的复选框时，公共(public)变量变为 True，然后函数 Topics 显示公共(public)主题以及所有者。

谢谢

Answer 1

models.BooleanField 呈现自己 as a checkbox .是 True或 False .所以:

# models.py

class Topic(models.Model):
    # ...
    public = models.BooleanField(default=True)


# forms.py

class TopicForm(forms.ModelForm):
    class Meta:
        model = Topic
        fields = ["text", "public"]
        labels = {"text": "", "public": "label for public"}

如果你也想接受 null值，那么你应该使用 models.NullBooleanField .
