Django 表单不是 sh

Question

由于某种原因，我的 forms.py 没有查看任何字段，而是只显示“添加”按钮，我不知道该怎么办了。如果知道自己在做什么的人能告诉我我做了什么或没做什么，我将不胜感激。

请注意，我是 Django 新手，谢谢。

这是我的观点.py：

from django.shortcuts import render
from django.utils import timezone
from .models import Measurement
from .forms import MeasurementForm
from django.views import generic


class IndexView(generic.ListView):
    model = Measurement
    context_object_name = 'measurement_list'
    template_name = 'index.html'
    queryset = Measurement.objects.all()


def new_measurement(request):
    if request.method == "POST":
        form = MeasurementForm(request.POST)
        if form.is_valid():
            measurement = form.save(commit=False)
            measurement.measurement_date = timezone.now()
            measurement.save()
    else:
        form = MeasurementForm()

    return render(request, 'index.html', {'form': form})

urls.py:

from django.urls import path
from . import views


urlpatterns = [
    path('', views.IndexView.as_view(), name='index'),
]

forms.py: 从 django 导入表格 从 .models 导入测量

class MeasurementForm(forms.ModelForm):
    class Meta:
        model = Measurement
        fields = ('measurement_value', 'measurement_unit')

index.html:

{% extends "base.html" %}

{% block content %}
    <h1>Climate Measurement Tool</h1>

    <h2>Add a new measurement</h2>
    <form method="POST" class="post-form">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit" class="save">Add</button>
    </form>

    <h2>Measurements</h2>
    {% if measurement_list %}
    <ul>
        {% for measurement in measurement_list %}
        <li>
            <p>{{ measurement }}</p>
        </li>
        {% endfor %}
    </ul>
    {% else %}
        <p>No measurements yet</p>
    {% endif %}    
{% endblock %}

new_measurement() 视图正确初始化表单实例并将其传递给模板。

不幸的是，该视图从未被调用。

urls.py 只定义了一个 url，由IndexView.as_view() 处理，它不会将表单实例传递给模板。
