Django:如何使用自定义模板制作表单？

Question

我有一个模特:

class Setting(models.Model):

    class Meta:
        abstract = True

    name = models.CharField(max_length=120, primary_key=True)
    description = models.CharField(max_length=300, blank=True)

class IntegerSetting(Setting):
    value = models.IntegerField()

我想创建一个看起来像这样的表单:

<form method="POST" action="">
     {% for model in models %}
     <label>{{model.name}}</label> <input value='{{model.value}}' />
     <p>{{model.description}}</p>
     {% endfor %}
</form>

我不太清楚如何去做这件事.也许我需要使用一个formset？

from django.forms.models import modelformset_factory
from apps.about.models import Setting, IntegerSetting

def site_settings(request):
    formset = modelformset_factory(IntegerSetting)()

    return render_to_response("about/admin/site-settings.html", {'formset': formset}, RequestContext(request, {}))

然后在模板中,我想要以不同于默认值的方式呈现表单.但是,我不太确定如何访问模型属性.这是正确的方法,还是我应该采取另一种方式来做这件事？

更新:这就是我目前正在做的事情.除了样式之外,它完全按照我的喜好呈现.但是,我觉得它非常hacky:

class SettingsForm(ModelForm):
    class Meta:
        model = IntegerSetting

    def as_table(self):
        bound_field = BoundField(self, self.fields['value'], 'value')
        return mark_safe("<tr><td><label>%s</label></td><td>%s\n<p class='help'>%s</p></td></tr>" % (self.instance.name,
                                                                       self.instance.description, 
                                                                       bound_field.__unicode__())) 

def edit_settings(request):
    forms = [SettingsForm(instance=intSetting) for intSetting in IntegerSetting.objects.all()]

    return render_to_response("admin/edit-settings.html", {'forms': forms}, RequestContext(request, {}))

edit-settings.html:

{% extends "admin/base_site.html" %}
{% block title %}System Settings{% endblock %}

{% block content %}
    <form method="post" action="">
        <table>
        {% for form in forms %}
        {{form}}
        {% endfor %}
        </table>
    </form>
{% endblock %}

有更好的方法吗？

此外,我不确定在提交表单时是否会遇到问题.

Answer 1

<form action="/contact/" method="post">
    {% for field in form %}
        <div class="fieldWrapper">
            {{ field.errors }}
            {{ field.label_tag }}: {{ field }}
        </div>
    {% endfor %}
    <p><input type="submit" value="Send message" /></p>
</form>

我认为你不需要这里的表格.如果您想要一个视图的自定义模板,请查看此处.如果你想创建自己的{{form.as_foobar}},只需子类forms.Form,如下所示:

class MyForm(forms.Form):
  def as_foobar(self):
    return self._html_output(
      normal_row = u'%(label)s %(field)s%(help_text)s',
      error_row = u'%s',
      row_ender = '',
      help_text_html = u' %s',
      errors_on_separate_row = False)

并在forms.py中使用它:

class ContactForm(MyForm):
  # ..
