我正在使用 cms Plone 构建一个包含其他两个模式的表单。

使用Group Forms，我已经能够包含两个模式的两个字段。但是，它们会丢失所有属性，例如隐藏或当我使用 datagridfield 构建表时。我想要做的是让这两个表单都带有它们的字段，并且在保存时能够将它们保存在单击链接的对象中作为父对象->对象1 [表单顶部]->对象2 [表格底部]

这是我的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()

此代码显示 IQuestion、IQuestionPart 的两个字段，而不考虑以下内容：form.mode(contype='hidden') 或 DataGridField 小部件。我找到了一种显示带有字段提示的正确表单的方法。

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。我现在正在尝试使用单独的表单和视图。

到目前为止，我的代码在这一点上：

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)

我正在为表单的呈现而苦苦挣扎，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中：

alsoProvides(self.form, IWrappedForm)

在视图的更新方法中，我需要在表单显示之前调用它。我还可以删除数据提取并将其移至表单。

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.AutoExtensibleFormmixin 的表单类才会关注模式表单提示。尝试将其用作 Group 表单类的 mixin（并提供schema此 mixin 查找的属性，而不是fields）：

from plone.autoform.base import AutoExtensibleForm

class QuestionPart(AutoExtensibleForm, group.Group):
    label = u'Question Part'
    schema = IQuestionPart
    template = ViewPageTemplateFile('questionpart_templates/view.pt')

这是我的最终代码，上面进行了更改。对象的索引存在问题。我需要创建一个简单的自定义视图。我忘记了表单上的模式属性。我还需要更改视图的更新方法。

class QuestionSinglePartForm(AutoExtensibleForm, form.Form):

    ignoreContext = True

    autoGroups = False

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

    @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

    @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

    @button.buttonAndHandler(u'Cancel')
    def handleCancel(self, action):
        print 'cancel'



class QuestionSinglePartView(object):

    schema = IQuestion
    additional = (IQuestionPart,)
    index = ViewPageTemplateFile('questionsinglepart_templates/questionsinglepart.pt')

        self.request = request
        self.form = QuestionSinglePartForm(context, request, self.schema, self.additional)
        alsoProvides(self.form, IWrappedForm)

    def magic(self, data, errors):
        pass
        """

        questionPart.hints = data['IQuestionPart.hints']
        questionPart.table = data['IQuestionPart.table']
        questionPart.contype = data['IQuestionPart.contype']
        questionPart.content = data['IQuestionPart.content']
        """
