Re: Django table with checkboxes

Hi,

I am actually looking for a quick help on the same issue. Trying to learn and create a delete button with checkbox's, 

Models:

class Customer(TimeStamp):

    name = models.CharField(max_length=30, unique=True)

    description = models.CharField(max_length=100, blank=True, help_text="Long-form name (optional)")

    comments = models.TextField(blank=True)

    class Meta:

        # ordering = ['name']

        ordering = ['-id']

    def __str__(self):

        return self.name

    def get_absolute_url(self):

        return reverse('App_CUS:customer_list')

Views.py:

class CustomerListView(ListView):

    queryset = Customer.objects.order_by('id')

    model = Customer

    paginate_by = 10

    context_object_name = 'customers'

    template_name = 'App_CUS/customer_list.html'

customer_list.html:

{% extends 'index.html' %}

{% load buttons %}

{% block content %}

<div class="pull-right">

    {% if perms.App_CUS.customer_add %}

        {% add_button 'App_CUS:customer_add' %}

        {% delete_button 'App_CUS:customer_delete' %}

    {% endif %}

</div>

<h1>{% block title %}Customers{% endblock %}</h1>

<div class="col-md-9">

<div class="table-responsive">

  <table class="table table-hover table-headings table-bordered">

    <thead>

      <tr>

        <th class="pk">

            <input class="toggle" title="Toggle all" type="checkbox">

        </th>

        <th>ID</th>

        <th>Customer Name</th>

        <th>Description</th>

       </tr>

    </thead>

    <tbody>

      {% for customer in customers %}

        <tr>

        <th class="pk">

            <input class="toggle" title="Toggle all" type="checkbox">

        </th>

          <td>{{ customer.pk }}</td>

          <td>{{ customer.name }}</td>

          <td>{{ customer.description }}</td>

        </tr>

      {% endfor %}

    </tbody>

  </table>

</div>

</div>

 

  {% if is_paginated %}

    <ul class="pagination">

      {% if page_obj.has_previous %}

        <li><a href="?page={{ page_obj.previous_page_number }}">&laquo;</a></li>

      {% else %}

        <li class="disabled"><span>&laquo;</span></li>

      {% endif %}

      {% for i in paginator.page_range %}

        {% if page_obj.number == i %}

          <li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li>

        {% else %}

          <li><a href="?page={{ i }}">{{ i }}</a></li>

        {% endif %}

      {% endfor %}

      {% if page_obj.has_next %}

        <li><a href="?page={{ page_obj.next_page_number }}">&raquo;</a></li>

      {% else %}

        <li class="disabled"><span>&raquo;</span></li>

      {% endif %}

    </ul>

  {% endif %}

{% endblock %}

Thanks,

Sorry for my late response.
I found a way how to do it.
My fist mistake was that I creat a view fo deleting books.
And my form action is pointing this url.
Afrer I changed it to point to "."
But I search for more pythonic way.
This is how i get checked checkboxes;
try:
    ch = []
    if request.method == 'POST':
      ch = request.POST.getlist('checkbox')
        #assert False

This is part of  my template.
<form name="bookform" action="." method="POST">
<td>
                <input type="checkbox" name="checkbox" id="checkbox[]"
value={{ book.id }}   />
                </td>
input type="submit" value="Send me">
But I read that I can generate form from model and add checkbox.
https://docs.djangoproject.com/en/dev/topics/forms/modelforms/
But at the moment I don't know how to implement it .
