Python 如何创建具有多个模式的z3c.form？

我正在使用cms Plone构建一个包含两个其他模式的表单

使用，我已经能够包含两个模式的两个字段。但是，当我使用datagridfield构建表时，它们会丢失所有属性，例如hidden或。我想做的是让这两个表单都有它们的字段，并且在保存时能够将它们保存在链接作为父对象单击的对象->对象1[表单顶部]->对象2[表单底部]

以下是我的python代码：

class QuestionPart(group.Group):
    label = u'Question Part'
    fields = field.Fields(IQuestionPart)
    template = ViewPageTemplateFile('questionpart_templates/view.pt')

 class Question(group.Group):
     label = u'Question'
     fields = field.Fields(IQuestion)
     template = ViewPageTemplateFile('question_templates/view.pt')

class QuestionSinglePart(group.GroupForm, form.AddForm):
    grok.name('register')
    grok.require('zope2.View')
    grok.context(ISiteRoot)
    label = u"Question with Single Part"

    ignoreContext = True
    enable_form_tabbing  = False

    groups = (Question,QuestionPart)

def update(self):
    super(QuestionSinglePart, self).update()

这段代码显示IQuestion和IQuestionPart的两个字段，而不考虑form.mode（contype='hidden'）或DataGridField小部件。 我找到了一种用字段提示显示正确表单的方法

class QuestionSinglePart(AutoExtensibleForm, form.AddForm):
    grok.require('zope2.View')
    grok.context(ISiteRoot)

    label = u"Question"
    schema = IQuestion
    additionalSchemata = (IQuestionPart,)                             

我觉得我还有很长的路要走。我和一些人谈过。我现在尝试使用一个单独的窗体和视图

到目前为止，我的代码是：

class QuestionSinglePartForm(AutoExtensibleForm, form.Form):

    ignoreContext = True

    autoGroups = True
    template = ViewPageTemplateFile('questionsinglepart_templates/questionsinglepartform.pt')

    @property
    def additionalSchemata(self):
        return self._additionalSchemata

    def __init__(self, context, request, schema, additional=()):
        self.context = context
        self.request = request
        if not IInterface.providedBy(schema):
            raise ValueError('Schema is not interface object')
        self._schema = schema
        if not all(IInterface.providedBy(s) for s in additional):
            raise ValueError('Additional schema is not interface')
        self._additionalSchemata = additional

class QuestionSinglePartView(object):

    schema = IQuestion
    additional = (IQuestionPart,)

    def __init__(self, context, request):
        self.context = context
        self.request = request
        self.form = QuestionSinglePartForm(context, request, self.schema, self.additional)

    def magic(self, data, errors):
        pass
        """
        question = Question()
        question.number = data['number']
        question.questionContent = data['questionContent']

        questionPart = QuestionPart()
        questionPart.typeOfQuestion = data['IQuestionPart.typeOfQuestion']
        questionPart.explanation = data['IQuestionPart.explanation'] 
        questionPart.fileSize = data['IQuestionPart.fileSize']
        questionPart.fileType = data['IQuestionPart.fileType']
        questionPart.hints = data['IQuestionPart.hints']
        questionPart.table = data['IQuestionPart.table']
        questionPart.contype = data['IQuestionPart.contype']
        questionPart.content = data['IQuestionPart.content']
        """

    def update(self, *args, **kwargs):
        if self.request.get('REQUEST_METHOD') == 'POST':
            data, errors = self.form.extractData()
            self.magic(data, errors)
        self.formdisplay = self.form.render()

    def __call__(self, *args, **kwargs):
        self.update(*args, **kwargs)
        return self.index(*args, **kwargs)

我正在努力呈现表单，并且QuestionSinglePart对象没有索引属性

在与一些plone开发人员一起工作了几个小时后，我们已经弄清楚了到底发生了什么

我遗漏了：

    @property
    def schema(self):
        return self._schema

我需要在视图中定义一个索引，如下所示：

index = ViewPageTemplateFile('questionsinglepart_templates/questionsinglepart.pt')

我需要将此添加到视图init：

alsoProvides(self.form, IWrappedForm)

在视图的update方法中，我需要在formdisplay之前调用它。我还可以删除数据提取并将其移动到表单中

def update(self, *args, **kwargs):
    self.form.update(*args, **kwargs)
    self.formdisplay = self.form.render()

---

我目前仍在努力将数据保存到对象中

只有包含

plone.autoform.base.AutoExtensibleForm

mixin的表单类才会注意模式表单提示。尝试将其用作组表单类的mixin（并提供此mixin查找的

架构

属性，而不是

字段

）：

这是我的最后一段代码，上面做了一些更改。对象的索引存在问题。我需要创建一个简单的自定义视图。我忘记了表单上架构的属性。我还需要更改视图的更新方法

class QuestionSinglePartForm(AutoExtensibleForm, form.Form):

    ignoreContext = True

    autoGroups = False

    def schema(self):
        return self._schema

            raise ValueError('Schema is not interface object')
        self._schema = schema
        if not all(IInterface.providedBy(s) for s in additional):
            raise ValueError('Additional schema is not interface')
        self._additionalSchemata = additional

    @button.buttonAndHandler(u'Save')
    def handleSave(self, action):
        data, errors = self.extractData()
        if errors:
            return False
        obj = self.createAndAdd(data)
        if obj is not None:
            # mark only as finished if we get the new object
            self._finishedAdd = True
            IStatusMessage(self.request).addStatusMessage(_(u"Changes saved"), "info")
        print data

谢谢你，大卫。从plone.autoform.base导入时，我会收到一个导入错误“ImportError:无法导入名称AutoExtensibleForm”。然而，当我改变基地，形成它的工作。除此之外，我收到一条错误消息，说Question没有updateActions属性。
