Python 使用Django获取要在HTML中显示的表单

所以我以前已经正确地显示了表单，我只是有点不明白为什么我在这样做的时候会使用某些单词，我想知道为什么我会使用不同的单词来显示不同的表单

{% extends "base.html" %}

{% block content %}

<div class="form-base">
    {% if registered %}
        <h1>Thank you for registering!</h1>
    {% else %}
        <h2>Register</h2>
        <form method="POST">
            {% csrf_token %}
            {{ user_form }}
            <input type="submit" value="Register" />
        </form>
    {% endif %}
</div>

{% endblock %}

在第一个示例（colorist_form.html）中，我使用的是

{{form}

，它确实可以显示表单

{% extends "base.html" %}

{% block content %}
    <div class="colorset-base">
        <h2>Create new post</h2>
        <p class="hint">Add hex codes for each color you would like to include.</p>
        <form id="postForm" action="{% url 'colorsets:new_color' %}" method="POST">
            {% csrf_token %}
            {{ form }}
            <button type="submit" class="submit btn btn-primary btn-large">Add Color Set</button>
        </form>
    </div>
{% endblock %}

同样在我的register.html中，我正在使用

{{user\u form}}

来显示表单

{% extends "base.html" %}

{% block content %}

<div class="form-base">
    {% if registered %}
        <h1>Thank you for registering!</h1>
    {% else %}
        <h2>Register</h2>
        <form method="POST">
            {% csrf_token %}
            {{ user_form }}
            <input type="submit" value="Register" />
        </form>
    {% endif %}
</div>

{% endblock %}

不确定这个问题是否需要所有这些代码，但我认为这不会有什么坏处

我有点不知所措（尽管我以前已经让它工作过），因此非常感谢您的帮助。

如果您使用“创建视图”，则不必编写表单，自动Django生成模型表单，因此应该如下所示：

class CreateWidgetView(LoginRequiredMixin,CreateView):
    login_url = '/login/'
    redirect_field_name = 'index.html'
    model = Widget
    fields = ['field', 'field2']

    def form_valid(self,form): #I Think this part is not neccesary
        self.object = form.save(commit=False)
        self.object.save()
        return super().form_valid(form)

单词“form”、“user\u form”或“widget\u form”没有什么特别之处，它们只是传递给模板的上下文中的键。例如，在继承FormMixin的视图中，@PauloAlmeida在我的例子中，为什么表单没有显示在页面上？为什么它只显示一个指向表单的按钮？

class Meta:

表单中的类不应该有paren。除此之外，我没有发现任何错误。@PauloAlmeida这没有影响任何事情，但谢谢你。相关的models.py和url.py可能对诊断问题也很有用。也许从帖子中删除所有不相关的东西，这只会增加噪音。一个URL.py、views.py、forms.py、models.py和template的链，只针对不起作用的表单，将有助于解决这个问题。虽然在html中，我只是将

{{form}}

？是的，就像在这个例子中一样，是的，我读到了，但我不明白为什么他们不谈论“form”这个词来自哪里，但那是因为FormView是为您设置的？不，一个不同于另一个，CreateView在模板小部件_form.html中创建表单作为表单。单词form是默认名称
