问题与Django模板'ifequal' [英] Issue with Django template 'ifequal'

问题描述

以下代码：

{% ifequal username AnonymousUser %}
    <p>Welcome</p>
{% else %} 
    <p> Welcome {{ username }}. Thanks for logging in.</p>     
{% endifequal %}

显示此：

Welcome AnonymousUser. Thanks for logging in.

什么？我不止一点我很确定我不需要提供额外的代码来了解我的问题。

What the? I'm more than a little miffed. I'm pretty sure i don't need to supply extra code for you to understand my problem.

我不认为这是一个不平等的问题。我有一个很好的处理方式。

I dont think it's an ifequal problem. I have a pretty good handle on that.

用户名来自：

username = request.user

这是否意味着此代码中的用户名不是字符串。我必须把它转换成一个字符串。

Does this mean username at this point in the code is not a string. Do i have to convert it to a string.

推荐答案

你需要比较一个字符串。使用这个：

You need to compare to a string. Use this:

{% ifequal smart_str(username).strip() "AnonymousUser" %}

这里是 Django文档检查与 ifequal 的相等性

Here's the Django documentation on checking equality with ifequal.

确保您的变量是一个字符串，还有一个被修剪的前导和尾随空格。

Ensure your variable is a string, and one that's trimmed of leading and trailing whitespaces as well.
