Question

我已经阅读了有关https://github.com/Atrox/sweetify-django的文档，但我不太明白，我已经在 Django 中下载并导入了 sweetify 的要求。我只是希望如果记录被更新，就会出现弹出消息（sweetify） 。

\n\n

def studentrecords(request):\n   if request.method == \'POST\':\n      id = request.POST.get("id")\n      update = StudentsEnrollmentRecord.objects.get(id=id)\n      update.Section = s\n      update.save()\n      sweetify.success(request, \'You did it\', text=\'Your Form has been Updated\',persistent=\'Hell yeah\')\n      return render(request, \'Homepage/selectrecord.html\')\n

\n\n

这是我的html

\n\n

{% load sweetify %}\n{% sweetify %}\n <form  method="post" action="/studentrecords/" enctype="multipart/form-data">{% csrf_token %}\n<table>\n    {% for student in myrecord %}\n    <tr>\n        <td>Control #</td>\n        <td><input type="text" name="id" value="{{student.id}}"></td>\n        <td><input type="submit"></td>\n    </tr>\n    <tr>\n        <td>Name: </td>\n        <td><input type="text" value="{{student.Student_Users.Firstname}} {{student.Student_Users.Lastname}} {{student.Student_Users.Middle_Initial}}"></td>\n        <td>Course/Track</td>\n        <td><input type="text" value="{{student.Courses}}"></td>\n    </tr>\n    <tr>\n        <td>Education Level: </td>\n        <td><input type="text" value="{{student.Education_Levels}}"></td>\n        <td>Strand: </td>\n        <td><input type="text" value="{{student.strands}}"></td>\n    </tr>\n    <tr>\n        <td>Section: </td>\n        <td>\n            <select name="section">\n                <option value="{{student.Section.id}}">{{student.Section}}</option>\n                {% for sections in section %}\n                <option value="{{sections.id}}">{{sections.Description}}</option>\n                {% endfor %}\n            </select>\n        </td>\n        <td>Payment Type: </td>\n        <td><input type="text" value="{{student.Payment_Type}}" class="myform"></td>\n    </tr>\n    {% endfor %}\n</table>\n </form>\n<script src="https://cdn.jsdelivr.net/npm/sweetalert2@9"></script>\n<script>\n    Swal.fire(\n  \'Good job!\',\n   \'Data Updated!\',\n  \'success\'\n)\n</script>\n

\n\n

我的设置.py

\n\n

INSTALLED_APPS = [\n    #my apps\n    \xe2\x80\xa6.\n    \'sweetify\'\n]\nSWEETIFY_SWEETALERT_LIBRARY = \'sweetalert2\'\n

\n\n

我没有收到任何错误，但没有出现弹出消息 （sweetify）

Answer 1

首先，如果您想收到有关任何记录更新的通知，我建议使用信号而不是检测请求方法。这是一种更集中、更强大的解决方案。只需将其添加到您的models.py：

from django.db.models.signals import post_save

@receiver(models.signals.post_save, sender=StudentsEnrollmentRecord)
def update_enrollment_record_handler(sender, updated_instance, **kwargs):
    """This method is called after every call of StudentsEnrollmentRecord.save"""
    sweetify.success(request, 'You did it', text='Your Form has been Updated',persistent='Hell yeah')

其次 - POST 旨在通过 RestAPI 创建对象，您应该切换到 UPDATE（包括所有对象字段）或 PUT（更新一些对象字段）。

第三 - 当您在 sweetify 行上方添加 print 语句时会发生什么？该打印运行吗？如果没有，那么您的整个设置甚至不会调用该studentrecords方法，您需要共享更多信息，以便我们可以复制情况和/或进一步提供建议。
