问题描述
我尝试了json过滤器,但出现找不到json"过滤器的错误.我在做什么错了?
I tried json filter, but I get "json" filter not found error. What I'm I doing wrong?
Error: Filter "json" not found at Object.exports.wrapFilter (......./node_modules/swig/lib/helpers.js:310:11)
<script type="text/javascript">
{{ places|json }}
</script>
对象是从mongodb传递的
object is passed from mongodb
this.displayMainPage = function(req, res, next) {
"use strict";
places.getPlaces(10, function(err, results) {
"use strict";
if (err) return next(err);
return res.render('places_template', {
places: results
});
});
}
我正在尝试输出json以传递到Google地图并在html中显示相同的数据
I'm trying to output json to pass to google maps and display the same data in html
推荐答案
对于1.0之前的Swig版本, json
过滤器改名为 json_encode
:
For versions of Swig prior to 1.0, the json
filter was instead named json_encode
:
{{ places|json_encode }}
出于兼容性考虑,1.0和更高版本将json_encode
保留为别名(json
.
And, for compatibility, 1.0 and later keep json_encode
as an alias of json
.
尽管如此,您还应该考虑升级Swig:
Though, you should also consider upgrading Swig:
$ npm install swig@0.14
npm WARN deprecated swig@0.14.0: v1.0.0 is a complete rewrite of Swig
from the ground up. Previous versions are no longer supported
