Django子模板可以将新块创建为钩子吗

问题描述：

我有以下情况：

base.html：

base.html:

{% block content %}{% endblock %}

child.html：

child.html:

{% extends 'base.html' %}
{% block content %}
   <p>Overriding content</p>
{% endblock %}
{% block child_block %}{% endblock %}

child_of_child.html：

child_of_child.html:

{% extends 'child.html' %}
{% block child_block %}
   <p>Overriding child</p>
{% endblock %}

在child.html中创建一个新的块child_block并拥有child_of_child .html扩展child.html并覆盖此块将不起作用，直到我还将base_html中的child_block也包含为一个钩子为止。

Creating a new block child_block in child.html and having child_of_child.html extending child.html and overriding this block does not work until I also include child_block in base.html as a hook.

不可能创建新的模板块/与根模板分开？如果是这样，是否有办法解决而不必在base.html中包含所有可能的钩子？

Is it not possible to create new template blocks / hooks apart from within the root template? If so, is there a way around it without having to include every possible hook inside base.html?

答

问题是您的 child_block 块不在 base.html 中的任何地方，因为它在现有块之外。呈现模板时它将出现在哪里？

The problem is that your child_block block doesn't live anywhere in base.html, because it's outside of existing blocks. Where would it appear when the template is rendered? There's simply no place defined for it.

完全可以使用子模板在其他块中定义块，然后再由其他子填充。因此，例如：

It's perfectly OK for child templates to define blocks inside other blocks, which are then populated by further children. So, for example:

{% extends 'base.html' %}
{% block content %}
   <p>Overriding content</p>
   {% block child_block %}{% endblock %}
{% endblock %}

绝对可以，并且您的结果将是：

works absolutely fine, and your result will be:

<p>Overriding content</p>
<p>Overriding child</p>
