Question

嗨，我对Django比较新。我有一个时间表供用户输入详细信息，当选择提交按钮时，这些填充字段中的数据将保存到数据库中。但我不知道为什么我的工作不起作用。随着值的保存，它将被检索并显示在另一个html文件的表格中。

timesheet.html

{% extends 'hrfinance/base.html' %}
{% block title %} Timesheet {% endblock %}
{% block link %}
{% load staticfiles %}
<link rel="stylesheet" href="{% static 'hrfinance/css/timesheet.css' %}"/>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
    /*to ensure that all the textbox and checkbox have been filled before users can submit*/
    function validation() {
        /*ensure start date has been entered*/
        if (!$('#studentid').val().trim()) {
            alert('Please fill in student ID field');
        }
        /*ensure start date has been entered*/
        if (!$('#studentname').val().trim()) {
            alert('Please fill in student name field');
        }
        /*ensure start date has been entered*/
        if (!$('#sdate').val().trim()) {
            alert('Please fill in start date field');
        }
        /*ensure end date has been entered*/
        if (!$('#edate').val().trim()) {
            alert('Please fill in end date field');
        }
        /*ensure checkbox has been ticked*/
        if (!$('#agree').is(':checked')) {
            alert('Please indicate that you have satisfied all the requirements');
        }
        else{
            console.log('ok')
      }
    }

models.py

#consists of all the details in the timesheet
class Timesheet(models.Model):
studentID = models.CharField("Student ID", max_length=8, primary_key=True, default="")
studentName = models.CharField("Student Name", max_length=500, default="")

endDate = models.DateField("End Date", max_length=8)

def __str__(self):
    return self.studentID

正如Fazil已经说过的那样，请查看文档。但是为了开始给你一点帮助：您缺少的是views.py中的表单验证，如：

def timesheet(request):
    user = request.user 
    form = yourform(request.POST or None)
    if form.is_valid():
        ....
        form.save()
    context = {
     'form':form,
     }
  return render(request, 'hrfinance/timesheet.html',context)

form.save命令将表单保存到数据库中。

您的<form>标记缺少该方法！（它应该是POST）。

我建议遵循一个教程（来自django docs或任何其他教程的教程），这样你就可以了解事情是如何运作的。

在一般情况下： 您的问题（特别是代码）越短，有人愿意阅读它的可能性就越大。应该删除"<br>"之类的内容。没有人关心你的形式。你的JS部分也应该被删除，因为它与问题无关。
