我如何获取文本字段而不是 ManyToManyField 关系的输入？

Question

这是模型关系：

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中：

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

在add.html中： `{{ form.as_p }}

标题、内容和选择输入显示在网页中。

<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>

我如何获取文本框而不是 name = models.CharField(max_length=100) 的输入。

Tag.name 是由空格分隔的字符串。我需要“标题、内容、标记名”才能在网页上显示。

请参阅 https:// /docs.djangoproject.com/en/dev/topics/forms/modelforms/#overriding-the-default-field-types-or-widgets

你会想要这样的东西：

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

然后您需要自己在视图中处理 POST 数据。
