You should be using a function to explicitly convert it to JSON, because of a few subtle differences between JSON and the default Python stringification:

您应该使用函数将其显式转换为JSON，因为JSON和默认Python字符串化之间存在一些细微差别：

• A string in JSON technically must be delimited with " rather than ', though parsers tend to accept the latter too (see the string rule on json.org)

  在技​​术上，JSON中的字符串必须用“而不是”分隔，尽管解析器也倾向于接受后者（请参阅json.org上的字符串规则）

• Bool literals are lowercase

  Bool文字是小写的

• If your data contains things other than numbers, strings, lists and dicts, using str on them will probably silently produce invalid JSON

  如果您的数据包含数字，字符串，列表和dicts以外的内容，那么使用str可能会无声地生成无效的JSON

Use a template filter such as django-jsonify:

使用模板过滤器，如django-jsonify：

{% load jsonify %}
...
{{ foo|jsonify }}

The reason I was experiencing this problem was because my dictionary actually included a unicode value. The toy example above was a simplification. when i ran str(val) before inserting val into the dict, the rendering occurred as expected.

我遇到这个问题的原因是因为我的字典实际上包含了一个unicode值。上面的玩具示例是简化。当我在将val插入dict之前运行str（val）时，渲染按预期发生。
