如何从 Django 页面的文本字段中获取输入，然后使用响应更新 SQL 表？

Question

我正在开发一个用于清理非活动 Tableau 工作簿的网站。登录此站点将允许我的用户查看他们的旧工作簿并决定保留哪些工作簿。

这将通过从 HTML 页面获取一些简单的文本输入来完成，K 表示保留 | D 删除。

然后，用户的响应将存储为 Python 变量，该变量将进入 if then 语句。 if then 语句基本上会更新 SQL 中的每一行，将 K 或 D 添加到名为“Marked_for_Deletion”的列中。

从那里，存储过程将运行，检查该列，并删除所有标有 D 的内容。

这可行吗？如果是这样，我将如何提取该输入并确保将其添加到正确的列/行？如果没有，您能否就我可以使用的替代方法提供任何建议？

谢谢！

编辑：这是我的表格的代码。

 <table class="blueTable">
        <thead>
            <tr>
                <th>Workbook Name</th>
                <th>Deletion Deadline</th>
                <th>Keep or Delete?</th>
            </tr>
        </thead>
        <tbody>
            {% for book in Workbooks %}
            <tr>
                <td>{{ book.name }}</td>
                <td>{{ book.owner_name }}</td>
                <td>
                    <label class="container" style="margin-bottom: 25px">
                        <input type="text" placeholder="(Enter K for Keep, D for Delete)">
                    </label>
                </td>
            </tr>
            {% endfor %}
        </tbody>
    </table>
    <form method="post">
        {% csrf_token %}
        <button type="submit" name="run_script">Submit</button>
    </form>
</body>

</html>

我希望能够从最后一个 td 标记中提取输入并将其存储在下面的提交按钮中。

我有点晚了，但我希望它可以帮助你。

urls.py

from django.urls import path

from workbook_app import views

app_name = 'workbook_app'

urlpatterns = [
    path('books/', views.BookListView.as_view(), name='books'),
    path('keep_or_delete/<int:pk>/', views.KeepOrDeleteView.as_view(), name='keep_or_delete'),
]

models.py

from django.db import models


class Book(models.Model):
    name = models.CharField(max_length=250)
    owner_name = models.CharField(max_length=250)
    marked_for_deletion = models.BooleanField(default=False)

views.py

from django.views.generic import ListView
from workbook_app.models import Book
from django.http import HttpResponse, HttpResponseRedirect
from django.views import View
from django.urls import reverse



class BookListView(ListView):
    template_name = 'workbook_app/books.html'

    def get_queryset(self):
        return Book.objects.all()


class KeepOrDeleteView(View):

    def post(self, request, pk):
        book = Book.objects.get(pk=pk)
        print(book, book.marked_for_deletion, not book.marked_for_deletion)
        book.marked_for_deletion = not book.marked_for_deletion
        book.save()

        url = reverse('workbook_app:books')
        return HttpResponseRedirect(url)

books.html

<div class="container">
<h2>Books</h2>
<table class="table">
  <tr>
    <th>Workbook Name</th>
    <th>Deletion Deadline</th>
    <th>Keep or Delete?</th>
  </tr>
  {% for book in object_list %}
  <tr>
    <td>{{book.name}}</td>
    <td>{{book.owner_name}}</td>
    <td>
      <form action="{% url 'workbook_app:keep_or_delete' pk=book.pk %}" method="POST">
        {% csrf_token %}
        <button type="submit" class="btn btn-{%if book.marked_for_deletion %}primary{% else%}danger{% endif %}">{%if book.marked_for_deletion %}Keep{% else%}Delete{% endif %}</button>
      </form>
    </td>
  </tr>
  {%endfor%}
</table>
