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ModelFormclass 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',)
然后是我的观点:
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))
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 %}
{% for recado in lista_recados %}
<p>{{ recado.nome }}</p>
<p>{{ recado.data }}</p>
<p>{{ recado.recado }}</p>
<br />
{% endfor %}
{% else %}
<p>Ainda não existem recados. Deixe o seu :)</p>
{% endif %}
</div>
这会在页面上正确生成表单,但是当我单击提交按钮时,它不会将数据保存在数据库中,现在我无法弄清楚要做什么。用观点尝试了一些事情,但没有任何效果。
有人可以帮帮我吗?非常感谢你。

您需要在视图中添加POST条件,验证表单然后保存: https://docs.djangoproject.com/en/dev/topics/forms/#using-a-form-in-a-view

如果您正在使用Django 1.5,请尝试THIS
也许您的观点可能是:
class RecadoFormView(FormView):
model_class = RecadoForm
template_name = 'recados/index.html'
def valid_form(self, form):
form.instance.save() # Or form.save()
return super(RecadoFormView, self).valid_form(form)
