Question

我正在尝试将参数传递给结构块，该结构块也有子结构块以通过选择块动态加载选项。用 init 方法尝试了这个概念，但还没有成功。下面是我的实现代码-

class DefaultThemeTemplate(blocks.StructBlock):
    template = blocks.ChoiceBlock(choices=[], label=_('Select a template'), required=False)

    def __init__(self, folder=None, **kwargs):
        self.template = blocks.ChoiceBlock(choices=get_designs(folder), label=_('Select a template'),
                                           required=False)
        super(DefaultThemeTemplate, self).__init__(**kwargs)

    class Meta:
        label = _('Default Theme')
        
        
class ThemeOneTemplate(blocks.StructBlock):
    template = blocks.ChoiceBlock(choices=[], label=_('Select a template'), required=False)

    def __init__(self, folder=None, **kwargs):
        self.template = blocks.ChoiceBlock(choices=get_designs(folder), label=_('Select a template'),
                                           required=False)
        super(ThemeOneTemplate, self).__init__(**kwargs)

    class Meta:
        label = _('Theme One')
        
        
class ThemeTwoTemplate(blocks.StructBlock):
    template = blocks.ChoiceBlock(choices=[], label=_('Select a template'), required=False)

    def __init__(self, folder=None, **kwargs):
        self.template = blocks.ChoiceBlock(choices=get_designs(folder), label=_('Select a template'),
                                           required=False)
        super(ThemeTwoTemplate, self).__init__(**kwargs)

    class Meta:
        label = _('Theme Two')


class Templates(blocks.StructBlock):
    default_theme = DefaultThemeTemplate(folder='', required=False)
    theme_one = ThemeOneTemplate(folder='', required=False)
    theme_two = ThemeTwoTemplate(folder='', required=False)

    def __init__(self, folder=None, **kwargs):
        self.default_theme = DefaultThemeTemplate(folder=folder, required=False)
        self.theme_one = ThemeOneTemplate(folder=folder, required=False)
        self.theme_two = ThemeTwoTemplate(folder=folder, required=False)
        super(Templates, self).__init__(**kwargs)

    class Meta:
        label = _('Template')
        
        
class StaticPage(Page):
    template = StreamField([
        ('template', Templates(required=False, folder='pages'))
    ], null=True, blank=True, verbose_name=_('Template'))

这是带有空白选择字段的屏幕截图 -

请帮我找出我做错了什么。提前致谢。

如果您在 __init__ 方法中修改子块，您需要先调用 super() ，然后在 self.child_blocks 字典中设置条目。设置 self.template 将不起作用，因为在 class 定义时，处理所有命名属性并将它们转换为子块列表的代码已经运行。

此外，您可能需要在您创建的区块上调用 set_name('template')。所以，像这样：

def __init__(self, folder=None, **kwargs):
    super().__init__(**kwargs)
    template_block = blocks.ChoiceBlock(choices=get_designs(folder), label=_('Select a template'), required=False)
    template_block.set_name('template')
    self.child_blocks['template'] = template_block
