为什么request.user的值看起来不一致

Question

我希望应用程序能够检查当前登录的用户是否是"；test2"；。我正在使用Django并运行以下代码：

<script>
console.log('{{ request.user }}')
{% if request.user == "test2" %}
console.log('The user that is currently logged in is test2.')
{% else %}
console.log('There was an error.')
{% endif %}
</script>

我的控制台正在记录以下内容：

test2
There was an error.

为什么会这样？我如何让应用程序识别"；test2"；是否已登录？

Answer 1

request.user.username

<script>
console.log('{{ request.user.username }}')
{% if request.user.username == "test2" %}
console.log('The user that is currently logged in is test2.')
{% else %}
console.log('There was an error.')
{% endif %}
</scrip

Answer 2

这可能是因为request.user实际上是对象，但__str__赋予了User的username属性。因此：

{% if request.user.username == "test2" %}
console.log('The user that is currently logged in is test2.')
{% else %}
console.log('There was an error.')
{% endif %}

*注意：-我假设test2是用户名，并且它是unique。

Answer 3

由于逻辑在模板中，因此在服务器端进行评估。这意味着request.user不是字符串，而是user实例。

console.log('{{ request.user }}')打印用户名的原因是在打印时，会调用__str__，返回username。

因此，您需要使用正确的字段进行检查，即user.username。

<script>
console.log('{{ request.user }}')
{% if request.user.username == "test2" %}
console.log('The user that is currently logged in is test2.')
{% else %}
console.log('There was an error.')
{% endif %}
</script>
