我正在学习一些Django,现在我在使用Forms时遇到了困难.我想要做的是创建一个表单,让人们在页面上留下消息,这些消息将显示在同一页面中(就像博客评论系统一样).我按照文档创建了一个类和ModelForm

class Recado(models.Model):
    recado = models.TextField()
    data = models.DateTimeField(auto_now_add=True)
    nome = models.CharField(max_length=100)
    email = models.EmailField(max_length=100)

    def __unicode__(self):
        return self.recado

class RecadoForm(ModelForm):
    class Meta:
        model = Recado
        exclude = ('data',)

那么这是我的看法:

def index(request):
    RecadoForm = modelform_factory(Recado, exclude=('data'))
    form = RecadoForm()
    lista_recados = Recado.objects.order_by('-data')
    template = loader.get_template('recados/index.html')
    context = Context({'lista_recados': lista_recados,})
    return render_to_response("recados/index.html", { "form": form,}, context_instance=RequestContext(request))

和模板:

<div class="conteudo-site conteudo-recados">
    <form method="post" action="salvar_recado">
        {% csrf_token %}            
        {{ form.as_p }}
        <br /><input class="button" type="submit" value="Deixar Recado" />
    </form>
    {% if lista_recados %} …
