Django - ListView - 循环模板不显示任何项目

这就是我想要实现的目标：

well_list.html

<thead>
  <tr>
    {% for item in well_info %}
    <th>item</th>
    {% endfor %}
  </tr>
</thead>

项目/urls.py

from django.conf.urls import url, include
from django.contrib import admin
from django.views.generic import TemplateView
from django.urls import path, re_path, include
from eric_base import views

urlpatterns = [
    path('contextual/', include('eric_base.urls')),
    path('well_list/', views.well_list)
]

views.py

from django.shortcuts import render
from django.views.generic import View, TemplateView, ListView, DetailView, CreateView, UpdateView, DeleteView

from . import models

class WellInfoListView(ListView):
    template_name = 'well_list.html'
    context_object_name = 'well_info'
    model = models.WellInfo

模型.py

from django.db import models
from django.urls import reverse


# Create your models here.
class WellInfo(models.Model):
    api = models.CharField(max_length=100, primary_key=True)
    name = models.CharField(max_length=100)
    region_location = models.CharField(max_length=100)
    spud_date = models.CharField(max_length=100)
    well_bore = models.CharField(max_length=100)
    rig_name = models.CharField(max_length=100)
    status = models.CharField(max_length=100)

    def get_absolute_url(self):
        return reverse("")

由于我正确定义了context_object_name = 'well_info' in views.py，我用过{% for item in well_info %}在 html 中，我期望至少能从模型属性中得到一些东西。但是当我运行这段代码时，我什么也没有得到。标题行就消失了，如下图所示：

我希望表头具有 models.py 中定义的属性名称，但显然它没有从中获取任何内容。为什么它没有从中获取任何属性models.py，以及如何仅将属性名称显示为列标题？

所以我希望表头是：

Api | Name | Region Location | Spud Date | Well Bore | Rig Name | Status

没有每个键的值。

您可以尝试使用 Model _meta API。在您的视图中，您可以将字段放入列表中，例如：

from django.shortcuts import render
from django.views.generic import View, TemplateView, ListView, DetailView, CreateView, UpdateView, DeleteView

from .models import WellInfo

class WellInfoListView(ListView):
    template_name = 'well_list.html'
    context_object_name = 'well_info'
    model = WellInfo

    def get_context_data(self, **kwargs):
        ctx = super(WellInfoListView, self).get_context_data(**kwargs)
        ctx['fields'] = [field.name for field in WellInfo._meta.get_fields()]
        return ctx

然后在你的模板中你可以有

<thead>
    {% for field in fields %}
    <th>{{ field }}</th>
    {% endfor %}
</thead>
