Django - 根据用户在表

Question

我有以下情况：在网站的用户区域，他可以在表格中看到他所有的房地产帖子。每个帖子都有一个“垃圾按钮”。当他按下我想要的按钮时，从DB中删除他选择的确切实例。

这是我的HTML。请注意，我使用了一个视图来访问数据库，然后从数据库中删除。但我不知道如何发送确切的参数来在DB上找到它。

<div class="container">
    <div class="col-xs-12">
        <h1>Olá, {{ request.user.first_name }}</h1>
    </div>
    <div class="row col-md-12 col-md-offset-0 custyle">
    <table class="table table-striped custab">
    <thead>
        <tr>
            <th>Imagem Principal</th>
            <th>Data Criação</th>

            <th>Tipo do Imóvel</th>

我正在实践我在书中学到的东西，所以我不想去参加AJAX。

Answer 1

将<form> POST内的按钮设置为视图，然后删除该实例。例如：

<强> HTML

<form action="{% url 'delete_estate %}" method="POST">
{% csrf_token %}
<input type="hidden" name="estate_id" value="{{ estate.id }}">
</form>

查看

def delete_estate(request):
    if request.method == "POST":
        estate_id = request.POST['estate_id']
        estate = Estate.objects.get(id=estate_id)
        estate.delete()

        messages.success(request, "Estate deleted successfully!")
        return redirect("/")

<强>网址

...
url(r'^delete-estate/$', views.delete_estate.as_view(), name='delete_estate'),
....

将模态放在for循环中，以便每个属性都有一个独特的模态。请记住将模态的ID更改为id="delete_{{ anuncio.id }}"，并使用删除按钮使用data-target="delete_{{ anuncio.id }}"激活相同的模态。在该模式中，您应该能够执行Hybrid对表单所说的内容并访问{{anuncio.id}}变量。

如果您还不知道，默认情况下已创建了ID。
