如何为ManyToManyField关系获得文本输入而非<select>？

Question

这是模型之间的关系：

class Tag(models.Model):
    name = models.CharField(max_length=100)
    description = models.CharField(max_length=500, null=True, blank=True)
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now_add=True)

class Post(models.Model):
    user = models.ForeignKey(User)
    tagfield = models.ManyToManyField(Tag)
    title = models.CharField(max_length=100)
    content = models.TextField()
    created = models.DateTimeField(default=datetime.datetime.now)
    modified = models.DateTimeField(default=datetime.datetime.now)

    def __unicode__(self):
        return '%s,%s' % (self.title,self.content)


class PostModelForm(forms.ModelForm):
    class Meta:
        model = Post


class PostModelFormNormalUser(forms.ModelForm):
    class Meta:
        model = Post
        exclude = ('user', 'created', 'modified')

在 views.py 文件中：

        form = PostModelFormNormalUser()
        context = {'form':form}
        return render_to_response('addpost.html', context, context_instance=RequestContext(request))

在 add.html 文件中：`{{ form.as_p }}`

网页上显示了标题、内容和选择输入框。

<p><label for="id_tagfield">Tagfield:</label> <select multiple="multiple" name="tagfield" id="id_tagfield">
</select> <span class="helptext"> Hold down "Control", or "Command" on a Mac, to select more than one.</span></p>

我该如何让 name = models.CharField(max_length=100) 显示为文本框，而不是输入框呢？

Tag.name 是用空格分开的字符串。我需要在网页上显示 '标题、内容、标签名'。

请查看这个链接：https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#overriding-the-default-field-types-or-widgets

你可能需要类似这样的东西：

class PostModelFormNormalUser(forms.ModelForm):
    class Meta:
        model = Post
        exclude = ('user', 'created', 'modified')
        widgets = {
            'tagfield': Textinput(),
        }

然后你需要在视图中自己处理POST数据。
