django 多模板继承 - 这是正确的风格吗? [英] django multiple template inheritance - is this the right style?
问题描述
哟
所以我有一个 base.html:
so i have a base.html:
<html>
<body>
<div id="header"> ... </div>
{% block main %}{% endblock %}
<div id="footer"> ... </div>
</body>
</html>
而且我还有一个页面显示用户的帖子:
and i also have a page that shows user's posts:
{% extends base.html %|
{% block main%}
<h1>welcome to yours posts hangout!</h1>
... snazzy code here that shows all the posts ...
{% endblock%}
现在，问题是，也许我还有一个这样的页面:
now, the problem is, maybe i have another page like this:
{% extends base.html %|
{% block main%}
<h1>look at all posts by all users!</h1>
... snazzy code here that shows all the posts by all the users ...
{% endblock%}
因为我们都属于mensa，我们可以看到我拥有的时髦代码正在重复 - 两次(为了同义反复！)
because we all belong to mensa, we can see that the snazzy code i have is being repeated - twice (for tautological fun!)
我不想重复这段代码 - 我的意思是，如果它会成为一个主要的麻烦，我会，但否则我想要一个定义了时髦代码的页面，然后滑动小改动上面和(可能)下面.
i don't want to repeat this code - i mean, if it is going to be a major hassle i will, but otherwise i'd like the one page that has the snazzy code defined, and then slip the small changes above and (possibly) below it in.
我对模板的理解是不稳定的 - 我认为这是去做的方式，有没有更好/标准化的方法?
my understanding of templates is shaky though - i think this is the way to go about doing it, is there a better/standardised way?
snazzy.html:
snazzy.html:
{% extends base.html %|
{% block aboveSnazzy%}
{% endblock %}
... snazzy code here that shows all the posts by all the users ...
{% block belowSnazzy%}
{% endblock %}
{% endblock%}
然后对于每个不同的部分，我可以有:
and then for each of the different pieces, i can have:
usersArea.html:
usersArea.html:
{% extends snazzy.html %|
{% block aboveSnazzy%}
<h1>welcome to yours posts hangout!</h1>
{% endblock %}
{% block belowSnazzy%}
<h1>i didn't think this far ahead in the example</h1>
{% endblock %}
{% endblock%}
其他部分的等等等等！
好的，所以我知道我可以只发送一个带有不同标题的参数或者你有什么 - 让我们假设上面的时髦的东西是，我不知道，展示一些我想要的其他模板或做一些非-不重要的.我在上面详述的方法"是做什么的?
ok, so i know i can just send in a parameter with a different header or what have you - let's pretend that the aboveSnazzy stuff is, i don't know, showing some other template i'd like or doing something non-trivial. Is what i've detailed above the "way" to do it?
干杯！
推荐答案
哟.:-)
答案取决于您的模板有多少共同点.
The answer depends on how much your templates have in common.
如果您的模板确实有很多共同点，即它们是您网站某个部分的页面，或者只是具有非常通用的结构，那么您的做法就是正确的.我只是认为您应该为块使用更具描述性的名称.
If your templates do have much in common, i.e. they are pages of some section of your site, or just have a very common structure, then your way of doing it would be correct. I just think that you should use more descriptive names for the blocks.
{% extends base.html %}
{% block page_heading %}{% endblock %}
... snazzy code here that shows all the posts by all the users ...
{% block extra_content %}{% endblock %}
如果您的模板没有太多共同点，但共享一些特定的内容块，那么情况就不同了，因为很难制作适当的继承结构.您应该使用 {% include %} 标签这个案例.例如，制作另一个显示帖子的模板，比如 _list_posts.html，然后在子模板中使用它.
If your templates don't have much in common, but share some specific block of content, then it's a different situation since it's difficult to make a properly inherited structure. You should use the {% include %} tag in this case. For example, make another template that shows posts, say _list_posts.html, then use it in the children templates.
{% extends base.html %}
{% block main %}
<h1>Welcome to your posts hangout!</h1>
{% include '_list_posts.html' %}
{% endblock %}
您也可以使用包含标签 为此.
那么，您应该选择哪个选项?试着回答这个问题:这两个模板应该有一个共同的父级吗?如果是，请选择第一个选项.否则，请选择第二个选项.
So, which option should you choose? Try to answer the question: should these two templates have a common parent? If yes, go for the first option. Otherwise, go for the second option.
