Django/Python - 使用表单按钮删除 sqlite3 数据库中的行
我想要一个删除按钮来删除 sqlite3 数据库中的一行。我已经快到了，但我不确定应该添加什么来将行的 html 中的 ID 发送到我的 views.py。这就是我所拥有的：
mailindex.html
<form action="" method="POST" enctype="multipart/form-data">
{% csrf_token %}
<div class="form-group">
<a href="{% url 'core:mail' mail.id %}" class="btn btn-secondary btn-sm">Manage</a>
<button type="submit" name="deletemail" value="deletemail" class="btn btn-secondary btn-sm">Delete</button>
</div>
</form>
views.py
class MailboxView(generic.ListView):
extra_context = {"mailbox_page": "active"}
model = MailMessage
context_object_name = 'mails'
template_name = 'core/mailbox/mailindex.html'
def post(self, request):
# if 'deletemail' in self.request.POST:
if request.POST.get('deletemail'):
mail = MailMessage.objects.get(pk=13)
mail.delete()
return HttpResponseRedirect(self.request.path_info)
它有效，从某种意义上说，当我按下删除按钮时，它会删除 ID = 13 的电子邮件。这是合乎逻辑的正如我所说的那样。那里有 13 个。我想用 mail.id 替换“13”，但我不知道该怎么做。我希望这是可能的：我希望它尽可能简单，这样就不会创建额外的网址，但同样不知道这是否可能......
I want to have a delete button to delete a row in my sqlite3 database. I'm almost there but I'm not sure what I should add to send the ID from my html of the row to my views.py. This is what I have:
mailindex.html
<form action="" method="POST" enctype="multipart/form-data">
{% csrf_token %}
<div class="form-group">
<a href="{% url 'core:mail' mail.id %}" class="btn btn-secondary btn-sm">Manage</a>
<button type="submit" name="deletemail" value="deletemail" class="btn btn-secondary btn-sm">Delete</button>
</div>
</form>
views.py
class MailboxView(generic.ListView):
extra_context = {"mailbox_page": "active"}
model = MailMessage
context_object_name = 'mails'
template_name = 'core/mailbox/mailindex.html'
def post(self, request):
# if 'deletemail' in self.request.POST:
if request.POST.get('deletemail'):
mail = MailMessage.objects.get(pk=13)
mail.delete()
return HttpResponseRedirect(self.request.path_info)
It works, in a sense that when I push the delete button it deletes email with ID = 13. Which is logical as I put no. 13 there. I would like to replace '13' with the mail.id, but I'm not sure how to do this. I hope it is possible: I would prefer it to be as simple as possible, so to not create an extra url, but again don't know if this is possible...

在类型中使用deletemail标签：隐藏另一个输入而不是按钮。
Use deletemail tag in type:hidden another input not button.
