python - Django如何在一个url地址调用多个 View ？

Question

我试图在 index.html 上显示由 new_measurement 定义的表单，但我只能设法让 IndexView() 工作。我尝试了 IndexView() 和 new_measurement() 之间的各种组合，但这些都没有奏效。我知道 IndexView() 不会传递与 new_measurement() 相关的任何内容，并且不会调用 new_measurement()，这是我的问题的核心。如果对 Django 有更多经验的人能告诉我我能做什么或应该做什么，我将不胜感激。谢谢。

这是我的 views.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'),
]

表单.py:

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 %}

您不能在一个 url 中映射多个 View ，但可以在一个 View 中执行多项工作。更新您的 views.py，因为您可以看到我正在该 View 中发送(查询列表和表单)

View .py

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()

    qs = Measurement.objects.all()
    context = {'form': form, 'measurement_list': qs}
    return render(request, 'index.html', context)

更新 urls.py

from django.urls import path
from . import views


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