我试图整合一个名为的应用程序, https://github.com/saebyn/django-credits" rel=“不跟随 noreferrer” >Django-Classififics , 但是在如何操控某些元素方面有困难 。

应用程序允许您通过管理部分创建一个类别和子字段, 该字段将被显示, 并允许用户在上述类别中创建一个职位 。 虽然 Django 管理允许您创建字段 :

“https://i.sstatic.net/5ozFt.png' alt=“DJango行政官”/>

并写到数据库:

""https://i.sstatic.net/siZ0b.png" alt="此处输入图像描述"/"

我无法找到如何调用这些字段并将其显示给用户。 目前, 只有标题字段被显示 。 我理解使用模型格式会允许我访问这些元素, 但我不确定如何将其与 BaseForm 整合起来( 在下面的应用程序中使用 ) :

class AdForm(BaseForm):
  def __init__(self, instance, data=None, files=None, auto_id= id_%s , prefix=None,
                         initial=None, error_class=ErrorList, label_suffix= : ,
                         empty_permitted=False):

    self.instance = instance
    object_data = ad_to_dict(self.instance)
    self.declared_fields = SortedDict()
    self.base_fields = fields_for_ad(self.instance)

    # if initial was provided, it should override the values from instance
    if initial is not None:
        object_data.update(initial)

    BaseForm.__init__(self, data, files, auto_id, prefix, object_data,
                      error_class, label_suffix, empty_permitted)

  def save(self, commit=True):
    if not commit:
        raise NotImplementedError("AdForm.save must commit it s changes.")

    if self.errors:
        raise ValueError("The ad could not be updated because the data didn t validate.")

    cleaned_data = self.cleaned_data

    # save fieldvalues for self.instance
    fields = field_list(self.instance)

    for field in fields:
        if field.enable_wysiwyg:
            value = unicode(stripHTML(cleaned_data[field.name]))
        else:
            value = unicode(cleaned_data[field.name])

        # strip words in settings.FORBIDDEN_WORDS
        for word in settings.FORBIDDEN_WORDS:
            value = value.replace(word,   )

        # title is stored directly in the ad, unlike all other editable fields
        if field.name ==  title :
            self.instance.title = value
            self.instance.save()
        else:
            # check to see if field.fieldvalue_set has a value with ad=self.instance
            try:
                # if it does, update
                fv = field.fieldvalue_set.get(ad=self.instance)
            except FieldValue.DoesNotExist:
                # otherwise, create a new one
                fv = field.fieldvalue_set.create(ad=self.instance)

            # XXX some ugly price fixing
            if field.name.endswith( price ):
                m = re.match( ^$?(d{1,3},?(d{3},?)*d{3}(.d{0,2})?|d{1,3}(.d{0,2})?|.d{1,2}?)$ , value)
                value = m.group(1)
                value.replace( , ,   )
                value =  %.2f  % float(value)

            fv.value = value
            fv.save()

    return self.instance

如何在以上 < code> AdForm 中显示所有创建的字段?

任何赞赏的例子。谢谢。
