问题描述
我继承了大量包含如下属性的.yaml文件：
I have inherited a large number of .yaml files that contain an attribute like this:
our_price: Our price is just <sup>$</sup><span class="amount">99.95</span> this month
现在，客户希望能够获取my_price，增加一些税费，以及在jinja模板中显示总价格。
Now, the client wants to be able to take our_price, add some taxes and fees, and display a total price in the jinja templates.
我想要做的是添加一个新属性，所以它看起来像这样：
What I'd like to do is add a new attribute, so it looks like this:
simple_price: 99.95
our_price: Our price is just <sup>$</sup><span class="amount">simple_price</span> this month
我尝试过使用别名，但似乎它们只能作为整个值使用节点。
I've tried using aliases, but it seems they only work as the entire value of the node.
有没有办法在YAML中设置它，或者从jinja2中的our_price字符串中提取浮点数？
Is there a way to set this up in YAML, or a way to pull out just the float from the our_price string in jinja2?
推荐答案
虽然我对jinja一无所知，但我认为你的问题在概念上类似于。
Although I don't know anything about jinja, I think your question is conceptually similar to this StackOverflow question.
简短的回答是，你不能像你/你的客户那样在YAML中进行字符串插值想要。我相信你必须将 simple_price 值传递给视图文件中的 our_price 值（或等效的jinja） ），并将YAML条目更改为：
The short answer is, you can't do string interpolation in YAML the way you/your client wants to. I believe you'll have to pass in the simple_price value to the our_price value from the view file (or jinja equivalent), and change the YAML entry to something like:
simple_price: 99.95
our_price: Our price is just <sup>$</sup><span class="amount">%{simple_price}</span>
或者，使用别名和锚点，您可以将价格和字符串作为数组带回到视图中，然后将它们连接成一个字符串：
Or, using aliases and anchors, you can bring back the price and string as an array to the view, and then join them into a single string there:
simple_price: &simple_price <sup>$</sup><span class="amount">99.95</span>
our_price:
- Our price is just
- *simple_price
