Question

到目前为止我的代码是：

            <div class="icon-and-title-flex">
                <img src="static/img/profile.png" class="appicon"></img>
                <div class="title-container">
                    <!-- REPLACE WITH YOUR APP NAME -->
                    <span class="text-title">Dashboard</span>
                    <br><div class="intertext-padding"></div>
                    <!-- REPLACE WITH YOUR DEV NAME -->
                    <span class="text-subtitle">by Student Accounts</span>
                    <br><div class="intertext-padding"></div>
                    <!-- REPLACE WITH YOUR APP PRICE -->
                    <span class="text-subtitle">{{ user.first_name }}</span>
                </div>

我有{{user.first_name}}，我想从models.py调用一个变量并在那里显示它。这是什么正确的语法？（这似乎不起作用。）

这是我的view.py，我不知道问题所在。

您的模板正在使用+----+----+----+ | | | | | | | | +----+----+----+ | | | | | | | | +----+----+----+ | | | | | | | | +----+----+----+，但您在views.py中的{{ user.first_name }}方法未将任何dashboard对象传递给模板，因此您的模板不会显示任何用户。听起来你想获得当前用户的信息，所以你的观点应该是：

user

您需要了解为什么需要从view方法传递变量才能使用它，doc就在这里。
