将JavaScript添加到扩展的Django模板中以进行Google Analytics（分析） [英] Adding javascript to an extended django template for google analytics
问题描述
我有一个不错的index.html小文件，它是扩展模板，其父文件是base.html文件（在我的情况下为base2.html）。我试图在网站上的某些文件中添加Google Analytics（分析）代码片段，事实证明，如果我在扩展模板的标记中添加了任何内容，就好像脚本代码会被忽略。我做错什么了吗？我知道我可以将它添加到base2.html中，但是那样就可以跟踪单次点击，因为那是我网站上很多页面的父级。
I have a nice little index.html file, it is an extended template and its parent is a base.html file (well in my case base2.html). I was trying to add a google analytics code snippet to some files on my site and it turns out, if I add anything in the tag on my extended templates, it is like the script code is ignored. Is there something I am doing wrong? I know I can add it just fine to base2.html, but then that would track for ever single hit since that is the parent for a lot of my pages on the site.
推荐答案
没有看到 base2.html 和 index.html ，很难回答，但最可能的罪魁祸首是您忘记了放置< script>< / script> 在父模板中存在的 {％block％} 中。请记住，对于 Django中的模板继承，父级定义了所有块的骨架，子级必须覆盖这些块-您可以使用 {{block.super}} 来继承所有父级该块的模板内容，然后添加任何其他内容。子模板中扩展的父骨架模板中不在块中的任何内容都不会呈现。
Without seeing the base2.html and index.html, it's pretty tough to answer, but the most likely culprit is that you forgot to put the <script></script> inside of a {% block %} that exists in the parent template. Remember that for template inheritance in Django, the parent defines a "skeleton" of all the blocks, and children must override those blocks— you can use {{ block.super }} to inherit all of the parent template's content for that block, then add any additional content. Any content in the child template that is not in a block in the parent "skeleton" template that it's extending doesn't get rendered.
# base2.html
<body>
{% block content %}
{% endblock content %}
{% block footer_scripts %}
<script src="foobar"> ...</script>
{% endblock footer_scripts %}
</body>
如果仅添加此内容，将无法正常工作：
If you were to just add this, it wouldn't work:
# index.html - DOES NOT WORK
{% extends 'base2.html' %}
<script>
// GA javascript
</script>
您需要将其包括在块中：
You need to include it in a block:
# index.html - DOES WORK
{% extends 'base2.html' %}
{% block footer_scripts %}
{{ block.super }}
<script>
// GA javascript
</script>
{% endblock %}
