我想在其模板中访问结构块默认ID

我想将流字段ID保存到模板中。

简而言之,在text_question.html中,我给出id = {{self.id}},但返回Nothing。

我想要这个,因为在question.html文件中,我希望它与{{ field.id}},返回流字段ID

换句话说,我想将{{field.id}}的值存储在text_question.html的ID字段中

models.py

class TextQuestionBlock(blocks.StructBlock):
    """Text Question"""

    question = blocks.CharBlock(required=True, help_text="Add your Question")
    is_save = blocks.BooleanBlock(label="Want to save this field ?", required=False)
    is_email = blocks.BooleanBlock(label="Want to get this field as an email ?", required=False)

    class Meta:  # noqa
        template = "question/question_field/text_question.html"
        icon = "edit"
        label = "Text Question"


@register_setting(icon='fa-commenting')
class QuestionSettings(BaseSetting):
    body = StreamField([
        ("text_question", TextQuestionBlock()),
    ], verbose_name='Question', blank=True)

    panels = [
        StreamFieldPanel('body')
    ]

    class Meta:
        verbose_name_plural = 'Question'
        verbose_name = 'Questions'

text_question.html

{% load tag_library %}
<input issave="{{self.is_save}}" isemail="{{ self.is_email }}" class="text_question" type="text" name="{{ self.question|to_name }}" id="{{ self.id }}" data-conv-question="{{ self.question }}"

question.html

<form name="question_form" action="" method="post" class="hidden">
            <div id="unique_id"></div>
                {% for field in question.body %}
                    {{ field.id }}
                {% endfor %}
            <input type="text" data-conv-question="test">
        </form>

谢谢!

ID不是块值的内置属性-而是StreamField容器用来跟踪其内容的一种机制。块值具有ID属性并不总是有意义的:例如,CharBlock的值是字符串,并且字符串上实际上不能具有.id属性。同样,StructBlock的子块也不会被赋予一个。

因此,该ID不会自动在块的模板上提供-如果需要,您需要通过{% include_block %} template标签从调用模板中显式传递它。例如:

{% for field in question.body %}
    {% if field.block_type == 'text_question' %}
        {% include_block field with block_id=field.id %}
    {% endif %}
{% endfor %}

这将使ID在text_question.html上作为变量block_id可用。
