Django模板中的嵌套块 [英] Nested blocks in Django templates

问题描述

我的Django应用程序中的master模板如下所示:

The master template in my Django app looks like this:

{% block parent %}
    Some text...
    {% block child %}
        Default content here...
    {% endblock child %}
    ...some more text
{% endblock parent %}

现在，应该以更改child块的方式覆盖此模板:

Now, this template should be overwritten in a way that the child block is changed:

{% extends "master.html" %}

{% block child %}
    New content here...
{% endblock child%}

但是，渲染保持不变(在此处打​​印默认内容...").我是否错过了明显的东西或嵌套块是不可能的? (或者违反DRY原理，我是否要重新定义parent块?)

However, the rendering stays the same (printing "default content here..."). Have I missed something obvious or are nested blocks not possible? (Or, violating the DRY principle, have I to re-define the parent block?)

编辑:如果需要的话，我正在使用Django 1.1.

I'm working with Django 1.1, if that matters.

推荐答案

好的，这是Django模板系统中的错误.对于大多数其他情况，本·詹姆斯是对的(请参阅上面对我的问题的评论).

OK, it's a bug in Django's template system. For most other cases, Ben James is right (see his comment to my question above).

在我的情况下，child块位于{% ifnotequal a b %}块内部，而 that 破坏了该块的继承.我认为这是一个错误，因为有数十种此类操作的自然用例.

In my case, the child block was inside a {% ifnotequal a b %} block, and that breaks the block inheritance. I consider that to be a bug, since there are dozens of natural use cases for such operations.
