在Django模板中使用变量作为字典键 [英] Use variable as dictionary key in Django template

问题描述

我想在Django模板的字典中使用变量作为键。我不能为我的生活找出如何做到这一点。如果我有一个名称或ID字段的产品，以及带有产品编号索引的评分字典，我可以说：

I'd like to use a variable as an key in a dictionary in a Django template. I can't for the life of me figure out how to do it. If I have a product with a name or ID field, and ratings dictionary with indices of the product IDs, I'd like to be able to say:

{% for product in product_list %}
     <h1>{{ ratings.product.id }}</h1>
{% endfor %}

在python中，这将通过一个简单的

In python this would be accomplished with a simple

ratings[product.id]

但我不能使它在模板中工作。我试过使用...没有骰子。想法？

But I can't make it work in the templates. I've tried using with... no dice. Ideas?

推荐答案

您需要事先准备好您的数据，在这种情况下，您应该将两个元组的列表传递给您的模板：

You need to prepare your data beforehand, in this case you should pass list of two-tuples to your template:

{% for product, rating in product_list %}
    <h1>{{ product.name }}</h1><p>{{ rating }}</p>
{% endfor %}
