django - 删除django中的多行

问题描述

我试图在 django 中同时删除几行。

如何通过单击复选框来简单地更改布尔字段“to_delete”的状态？

我正在使用数据表。The way how I am doing it is to create a boolean to_delete in my model, when the checkbox is selected, I am calling the function delete_multiple_company in my view. 但是，这不起作用。任何想法，请我做错了什么。非常感谢，

我已经创建了我的视图：

视图.py

def delete_multiple_company(request, company_id):
    company = get_object_or_404(Company, pk=company_id)
    company = Company.objects.get(pk=company_id)
    company.objects.filter(to_delete=True).delete()    
    return HttpResponseRedirect(reverse("company:index_company"))

网址.py

 url(r'^(?P<company_id>[0-9]+)/delete_multiple_company/$', views.delete_multiple_company, name='delete_multiple_company'),

模型.py

class Company(models.Model):
    to_delete = models.BooleanField(default=False)

索引.html

<a href="{% url 'company:delete_multiple_company' company.id %}" id="table" class="btn btn-default btn-sm active float: right" style="float: right;"><span class="fa fa-plus"></span>Delete Companies</a>

<table id="dtBasicExample" class="table table-striped table-hover">
     <thead>
        <tr>
           <th>Select</th>
           <th>#</th>
           <th>Checked ?</th> 
        </tr>
     </thead>
        <tbody>
           {% for company in companys.all %}
        <tr>
           <td id="{{ company.id }}"><input type="checkbox" class="companyCheckbox" name="checkedbox" id="{{ company.id }}" value="{{ company.id }}"></td>                              
           <td>{{ company.id }}</td>
           <td>{{ company.to_delete }}</td>
       </tr>
           {% endfor %}
                                 
        </tbody>
</table>

解决方案

我遇到了和你类似的问题，我所做的就是放在一个表格中。

索引.py

<form method="POST" class="post-form">{% csrf_token %} 
    <button type="submit" class="save btn btn-default">Delete</button>
<span class="fa fa-plus"></span>Delete Companies</a>

<table id="dtBasicExample" class="table table-striped table-hover">
     <thead>
        <tr>
           <th>Select</th>
           <th>#</th>
           <th>Checked ?</th> 
        </tr>
     </thead>
        <tbody>
           {% for company in companys.all %}
        <tr>
           <td id="{{ company.id }}"><input type="checkbox" class="companyCheckbox" name="checkedbox" id="{{ company.id }}" value="{{ company.id }}"></td>                              
           <td>{{ company.id }}</td>
           <td>{{ company.to_delete }}</td>
       </tr>
           {% endfor %}
                                 
        </tbody>
</table>
<button type="submit" class="save btn btn-default">Delete</button>
</form>

在我看来，单击按钮然后触发 POST 方法。

视图.py

def index(request):
    if request.method == 'POST':
        print('I made it here')
        # Put your code here, note you will return a dict, so some trial and error should be expected
