如何为组内的字段自定义 z3c.form 小部件(字段集)

How to customize z3c.form widget for fields inside groups (fieldsets)

我有一个 Plone 自定义控制面板注册表,我正在尝试使用众所周知的方法为 zope.schema.Textzope.schema.TextField 自定义一些小部件属性。

我通常以这种方式自定义 updateWidgets

def updateWidgets(self):
    super(MyEditForm, self).updateWidgets()
    self.widgets['my_text_area'].style = 'width: 100%'
    self.widgets['my_text_area'].rows = 7

但现在我正在处理一个字段被分成两个字段集的表单:

class MySettingsEditForm(controlpanel.RegistryEditForm):
    schema = IMySettingsSchema
    groups = (Form1, Form2)
    # fields = nothing

如果我尝试访问 self.widgets['my_text_area'],我会得到 KeyError。似乎因为我没有定义 fields 属性,所以我无法直接访问小部件。

我发现我有 groups,所以我可以调用类似 self.groups[0].fields['my_text_area'] 的东西,但我仍然找不到访问组内字段的小部件的方法。

如何在使用组时自定义小部件属性?

我想你需要的是玩小部件子表单,看这段代码:

def fix_table_widget(self, name, widgets):
    sub_widgets = widgets[name].widgets
    for widget in sub_widgets:
        new_label = widget.subform.widgets['weekday'].value
        widget.subform.widgets['selected'].items[0]['label'] = new_label
        widget.subform.widgets['weekday'].mode = 'hidden'

def schoolrequest_customizations(self):
    ''' Customizations for the schoolrequest base views
    '''
    for group in self.groups:
        widgets = group.widgets
        if 'table_bus_to_school' in widgets:
            self.block_widget_table('table_bus_to_school', widgets)
            self.fix_table_widget('table_bus_to_school', widgets)

        if 'table_bus_to_home' in widgets:
            self.block_widget_table('table_bus_to_home', widgets)
            self.fix_table_widget('table_bus_to_home', widgets)

def update(self):
    super(MyForm, self).update()
    self.schoolrequest_customizations()
