python - ImportError：无法从“userUpdate.models”导入名称“passUser”

问题描述

大家好，我正在尝试使用 django 构建一个网站，该网站从表单中获取信息并使用这些参数进行 api 调用。我是 django 的新手，我为此建立了一个模型，但我无法导入它说的这个模型

在 Windows cmd 上。我在没有制作模型的情况下尝试了这个，但如果我不使用模型，我就无法将表单呈现给模板。

这是我的 home.html

<div class="u-form u-form-1">
    <form action="{% url 'userPassreset' %}" method="post" class="u-clearfix u-form-spacing-15 u-form-vertical u-inner-form" style="padding: 15px;" source="custom" name="send">
    {% csrf_token %}
        <div class="u-form-group u-form-name u-form-group-1">
            {{form.as_p}}
            {{form.username}}
        </div> 
        <div class="u-align-right u-form-group u-form-submit u-form-group-6">
            <input type="submit" value="Sadece Mesaj Gönder" class="u-active-white u-border-0 u-border-radius-10 u-btn u-btn-round u-btn-submit u-button-style u-palette-2-base u-btn-1" name="sendmessage">

解决方案

它是通过从模型中删除“从。导入视图”来解决的。感谢评论中的@blondelg
