[英]passing an object to nunjucks template in node express
I am passing an object in Express to a Nunjucks template 我将Express中的对象传递给Nunjucks模板
app.get('/purchase', function (req, res) {
purchase_data = JSON.stringify(req.query);
res.render('purchase', {"purchase": purchase_data});
})
------------------------
<ul>
{% for key,value in purchase %}
<li>{{key}} | {{value}}</li>
{% endfor %}
</ul>
The output is literally each and every letter of the value property. 输出实际上是value属性的每个字母。 For example: {"quantity": "1"} becomes 0 |
例如:{“quantity”:“1”}变为0 | { 1 |
{1 | " 2 | q 3 | u 4 | a 5 | n 6 | t 7 | i 8 | t 9 | y 10 | " 11 |
“2 | q 3 | u 4 | a 5 | n 6 | t 7 | i 8 | t 9 | y 10 |”11 | : 12 |
:12 | " 13 | 1 14 | "
“13 | 1 14 |”
Not that experiences with nunjucks, and for that matter express, but this is a common enough task. 不是那种与nunjucks的经历,并且就此而言,但这是一项非常普遍的任务。 In nudge in the right direction would be very much appreciated.
在正确的方向推动将非常感激。

No, you're not. 不你不是。 You're passing a string:
你传递一个字符串:
purchase_data = JSON.stringify(req.query); // make a string
res.render('purchase', {"purchase": purchase_data}); // pass the string to the template
Instead, just pass the object as-is: 相反,只需按原样传递对象:
res.render('purchase', { purchase : req.query });
